12.1 House exterior
12.1.1 Access to the main entrance
Up to the main entrance, be it from a sidewalk, driveway, or garage, it shall:
be served with:
a path of travel in accordance with CSA/ASC B652 clause 4.3.2 and 5.2.1; or
a lift in accordance with CSA/ASC B652 clause 5.8.2.2.(a) and (c); or
Design for accessible-ready: have designed exterior paths conforming to sentence a). The path shall require no destructive modifications to the structural, electrical, plumbing, or HVAC systems (see Annex B).
Note: Housing constructed at ground level with a low threshold is most desirable from an accessibility standpoint. However, this can present challenges in certain situations. Some situations are sloped lots, when an occupied basement is desired, when there are below-grade units, or when protection from the weather is not possible resulting in building envelope issues. Nevertheless, at-ground level construction should be considered, when possible, as it provides reasonable means to achieve multiple requirements within this Standard and CSA/ASC B652. Additionally, as with most designs for accessible-ready, it is preferrable to meet this requirement through a method other than the accessible-ready design approach (i.e., by constructing a path of travel that conforms to the requirements of CSA/ASC B652). However, even when a path of travel that conforms with CSA/ASC B652 is installed, considering potential future installation of a different path of travel is recommended to accommodate changing needs and requirements. When the design for accessible-ready is used, the intent is to allow homeowners to meet their current needs, while considering their future needs or the needs of future occupants. This can also be leveraged when the design for accessible-ready is not used.
12.1.1.1 Entrance doors
Doors serving accessible-ready houses shall comply with CSA/ASC B652 clause 5.7, and Clauses 12.3.2.7 and 12.3.2.8 of this Standard.
Note: With the other accessible-ready features in this Standard, achieving the wider doorways in compliance with CSA/ASC B652 clause 5.7.1 is easier and more economical. With the complexity involved in enlarging doorways, even if framed in an accessible-ready manner (including accounting for light switches), it is most economical to achieve the doorway dimensions from the initial construction.
12.1.2 Access to balconies and exterior amenities
12.1.2.1 Balconies
Where an accessible-ready house is provided with a balcony, backyard, or access to an outdoor amenity space on the ground level, such space shall:
be served with a path of travel in accordance with CSA/ASC B652 clause 4.3.2 and 5.2.1;
be served by a minimum clear floor space in accordance with CSA/ASC B652 clause 4.4.2 b); or
Design for accessible-ready (DAR): have designed exterior paths conforming to sentences (a)(i) and (a)(ii). The path shall require no destructive modifications to the structural, electrical, plumbing, or HVAC systems (see Annex B).
Where interior and exterior access is available to a balcony, backyard, or access to an outdoor amenity space on the first storey, both interior and exterior access shall:
be served by a path of travel in accordance with sentence (a); or
Design for accessible-ready (DAR): have designed interior and exterior paths conforming to sentence (a). The path shall require no destructive modifications to the structural, electrical, plumbing, or HVAC systems (see Annex B).
12.1.2.2 Exterior amenities
Exterior amenities shall:
be served with a path of travel in accordance with CSA/ASC B652 clause 4.3.2 and 5.2.1;
be served with a ramp conforming to CSA/ASC B652 clause 5.5; or
Design for accessible-ready (DAR): have designed exterior paths conforming to Clause 12.1.2.1 and 12.1.3. The path shall require no destructive modifications to the structural, electrical, plumbing, or HVAC systems (see Annex B).
Note: This Clause is intended to ensure that large trees, retaining walls, and similar structures do not encroach into an area designated for a future feature (e.g., ramp), as this could make the future installation of the feature significantly more costly or challenging.
12.1.3 Exterior paths of travel
12.1.3.1 Landscaping
Where design for accessible-ready (DAR) indicates the presence of an exterior path of travel as per this Standard or CSA/ASC B652 (i.e., an accessible ready exterior path of travel), landscaping that may obstruct, overflow, or fall onto the accessible-ready feature shall:
form part of the future accessible feature; or
where the landscaping must be removed, it shall:
be removable using standard hand tools (e.g. gardening tools, shovels, picks, crowbars, etc.); and
not require a permit for removal or demolition of the landscaping (e.g. trees).
Note 1: For a discussion of landscaping for accessible houses, see CSA/ASC B652 clause 5.2.2.
Note 2: This clause is intended to ensure that large trees, retaining walls, and similar structures do not encroach into an area designated for a future feature (e.g., ramp), as this could make the future installation of the feature significantly more costly or challenging.
Note 3: The mature sizes of trees, plants, and shrubs, along with maintenance concerns for paths, are considered.
12.1.3.2 Exterior stairs
Exterior stairs shall be designed and constructed in compliance with clause 5.6 of CSA B652.
Note: This requirement is included in this Standard because exterior steps can significantly affect safety and functionality of the exterior space. The CSA/ASC B652 standard has special requirements for exterior stairs that should be considered during the design and construction. In particular, controlling surface water drainage on stair steps and landings. Practical considerations for the movement and constructability of stairs, particularly for concrete and lumber (wood) stairs is important. Addressing movement due to weather and settlement is important in achieving stairs that function as designed over their service life. Good design of the stair treads, handrails, risers, etc. can have a significant impact on the stairs and should be thoroughly considered in the design.
,
12.2 Parking and garages
12.2.1 Access to the main entrance
Where there is a driveway and garage, access shall be provided into the home from the main entrance and garage entrance (as per Clause 12.1) by:
a path of travel in accordance with clause 12.3.3.
Design for accessible-ready (DAR): have a ramp designed in accordance with CSA/ASC B652 clause 5.5. The construction of the ramp shall require no destructive modifications to the structural, electrical, plumbing, or HVAC systems (see Annex B), or
Design for accessible-ready (DAR): have provisions for a lift complying with CSA/ASC B652 clause 5.8.2.2 designed. The installation of the lift shall require no destructive modifications to the structural, electrical, plumbing, or HVAC systems.
Note: This Clause is intended for private garages and driveways assigned to a single housing unit, whether it is a detached house, semi-detached house, or town house. The ideal situation would be to have the path of travel from the driveway or garage comply with sentence a). However, if complying with this statement eliminates the possibility of a garage or constrains a homeowner from better utilizing the space, then the design for accessible-ready in sentence b) or c) should be considered. It should be noted that this applies to both entrances.
12.2.2 Shared parking amenities serving houses
For shared parking amenities serving houses, assigned accessible parking in accordance with CSA/ASC B652 clause 5.3.2, or garages designed in accordance with CSA/ASC B652 clause 5.3.3 must be provided.
Note: This Clause is intended for parking spaces that are within a parking lot serving multiple housing units, even where individual parking spots are assigned to specific units. If the parking spots can be assigned to more than one unit, then This clause is applicable.
12.2.3 Parking spaces serving only an accessible-ready house
Design for accessible-ready (DAR): parking spaces serving only an accessible-ready house shall be designed in accordance with CSA/ASC B652 clause 5.3.1 and clause 5.3.2. The design shall allow the area allowances to be achieved without destructive modifications to the structural, electrical, plumbing, or HVAC systems.
Note 1: This requirement is specifically for parking spaces, and not for parking garages, driveways, or carports. This only applies to a parking space that is assigned to be serving only an accessible-ready house. Since this parking space will only be serving that accessible-ready house, expanding that space to allow the required areas specified by CSA/ASC B652 needs to be relatively easy (i.e., no destructive modifications to the structural, electrical, plumbing, or HVAC systems).
Note 2: In most cases, it would be more effective to build the space in accordance with CSA/ASC B652 from the onset.
12.2.4 Parking garages or carports only serving an accessible-ready house
Where parking garages or carports serving only an accessible-ready house, the parking garage shall:
have a parking space (i.e., driveway) leading up to the parking garage or carport that is a minimum of 4600 mm wide by 8600 mm long; or
be designed in accordance with CSA/ASC B652 clause 5.3.3 and clause 5.3.4.
Note: In garages and carports, it is important to plan for convenient charging of mobility devices by considering the placement and number of electrical outlets. While current electrical and building codes ensure a basic number and distribution of receptacles, it is advisable to thoughtfully assess whether additional outlets are necessary to meet those charging needs.
,
12.3 Interior
12.3.1 Rooms and spaces
Accessible-ready houses shall be designed such that they have at least:
one bathroom in accordance with Clause 12.3.10; that bathroom is referred to as the “accessible-ready bathroom”;
one kitchen in accordance with clause 12.3.11;
one bedroom in accordance with clause 12.3.12;
one laundry room in accordance with clause 12.3.13; and
if present, one entryway, dining room, living room be served with a path of travel in accordance with clause 12.3.3.
Note 1: This Clause acknowledges that bathrooms, kitchens, and laundry rooms, due to their mechanical and electrical systems, pose unique challenges. It also recognizes that many occupants may need or want a small powder room, kitchenette, or similar space to enhance their home's functionality. Therefore, despite the complexity of integrating MEP systems within walls, it is worth ensuring that at least one of each room type is accessible-ready. This approach increases the probability that the house can be readily adapted to meet the needs of various occupants over time. While it is preferred that all rooms be accessible-ready, only one of each is required.
Note 2: It is recommended to consult CSA B652 clause 4.9 for window design which requires operating controls to be at an accessible height if present, and the lower edge (sill) not be higher than 750 mm. It is recommended to comply wherever possible with that clause to improve accessibility.
12.3.2 Doors
12.3.2.1 Doors and doorways openings
The clear opening width of a doorway shall be in compliance with CSA/ASC B652 clause 5.7.1.
Note: With the accessibility features outlined in this Standard, achieving wider doorways in compliance with CSA/ASC B652, clause 5.7.1 becomes more straightforward and cost-effective than retrofitting them. Given the complexities of enlarging doorways, even when framed in an accessibility-ready manner (such as accounting for light switches), it is most economical to ensure the correct doorway dimensions during the initial construction.
12.3.2.2 Maneuvering area at doors
Doorways shall:
have a level, clear, and unobstructed maneuvering area that extends for the full height of the door and is not less than:
600 mm beyond the latch-side on the pull side;
300 mm beyond the latch-side on the push side;
300 mm on each side of a sliding door;
the width of the path of travel serving the door, but not less than 1200 mm for interior spaces and not less than 1500 mm for exterior spaces; and
perpendicular to the door, a depth (or width) not less than the width of the path of travel.
Design for accessible-ready: the maneuvering area at doors shall be designed such that the maneuvering area can be constructed meeting the requirements of sentence a) without significant modifications to the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note 1: The option stated in sentence b) would only be used if the maneuvering area specified in sentence a) would lead to a loss of a living room, bedroom, or bathroom.
12.3.2.3 Two doors in series
Where there are two doors in a series, they shall:
be designed and constructed as per CSA/ASC B652 clause 5.7.3;
Design for accessible-ready (DAR): be designed such that one of the doors can be removed without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C); or
Design for accessible-ready (DAR): they shall be designed such that the required distance as per CSA/ASC B652 clause 5.7.3 can be achieved without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note 1: The option stated in sentence b) would only be used if the maneuvering area specified in sentence a) would affect a living room, bedroom, or bathroom.
Note 2: This requirement may have space limitations and therefore an accessible-ready option is considered. However, since this option may only be preferred when it affects other space, rooms, or functions, it is recommended that the maneuvering areas at the doors be attempted to be achieved as per sentence a). Therefore, the commentary follows the same logic as that given in Clause 12.3.3.
12.3.2.4 Doors and doorways thresholds
Thresholds shall be as required by CSA/ASC B652 clause 5.7.4.
12.3.2.5 Door hardware
Doors shall be designed and constructed to accept door hardware that complies with CSA/ASC B652 clause 5.7.5.
Note: Since door hardware is typically a matter of taste and is sometimes not regulated by authorities having jurisdiction for homes, the objective is to merely ensure that it can be easily replaced with compliant hardware.
12.3.2.6 Door-opening force
The design and the construction of door openings shall accept doors that comply with CSA/ASC B652 clause 5.7.6.
Note: Since doors are typically a matter of taste and is sometimes not regulated by authorities having jurisdiction for homes, the objective is to merely ensure that they can be easily replaced with compliant doors.
12.3.2.7 Power-assisted doors
Roughed-in electrical shall be provided for the future installation of a power-assisted door at the accessible-ready bathroom referred to in Clauses 12.3.1 and 12.3.10.1, main entrance, and garage entrance.
Note: See CSA/ASC B652 clause 5.7.7 for the requirements for power assisted doors, their operation, and their control.
Other than the cost of the power-assisted door motion unit, the highest cost is the cost of the electrical connection. The cost of the motion unit itself is not significantly affected if it is installed during original construction, or during a retrofit, if and when required. However, the cost of the electrical installation is lower during original construction than it is as part of a retrofit. As a result, the electrical rough-in is made as part of the wiring of the housing during original construction, thus providing maximum flexibility. Furthermore, this rough-in, while not in use for the motion unit, could be used as a receptacle on a dedicated circuit that could provide additional benefit to the occupant prior to the installation of the power-assisted doors.
12.3.2.8 Door viewers
Where the main entrance door is not served by a vision panel either in the door or off to the side, the main entrance door shall be equipped with a single door viewer installed at 1500 mm to 1700 mm above the finished floor with the ability to install a second door viewer at 1000 to 1200 mm above the finished floor.
Note: The cost of installing a door viewer is typically not considered prohibitive. However, if the door is not compatible with installing a door viewer at the required height, then the cost of installation of the viewer may be prohibitive. Therefore, this requirement is put in place to ensure that is not the case.
12.3.2.9 Door vision panel and side lights
Where provided, the door opening shall be compatible to receive a door where the vision panel in the door or the sidelight comply with CSA/ASC B652 clause 5.7.9.
Note: Since exterior doors are features that homeowners have specific preference for, it is important to provide flexibility while still allowing future users to efficiently modify them according to their own preferences. This clause aims at allowing users to choose their own door and set the vision panel as they desire, while still ensuring that the framing is built in a manner that can accept or receive a door complying with CSA/ASC B652.
12.3.3 Area allowances for paths of travel
Paths of travel shall:
have a width of at least 1200 mm for interior environments, and 1500 mm for exterior environment, except
for short indentations up to 600 mm in length, the width shall be at least 860 mm; and
for doorways, the width shall be at least 860 mm with a maneuvering area in accordance with clause 12.3.2.2.
Design for accessible-ready (DAR): The path of travel shall be designed such that a path of travel can be constructed meeting the requirements of sentence a) without significant modifications to the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note 1: It is recommended that this option only be used if the clear floor space specified in sentence a) would affect a living room, bedroom, or bathroom.
Note 2: The requirements for area allowances stipulated in CSA/ASC B652:23 provide a usable space for the highest possible percentage of people. Therefore, area allowances and space requirements are recommended to be achieved whenever possible. Within the concept of accessible-ready housing, area allowances and space requirements may affect layout options. This is because adapting space requirements may involve moving walls. At the same time, these space requirements, particularly for smaller houses, may affect the functionality and use of the space for various users, such as a bedroom, an office space, a closet, or a bathroom, all of which may benefit some occupants more than the space requirement. As a result, despite the need to relocate walls, this standard is aimed at providing provision to allow for the accessible-ready approach while making removing walls easier. This is achieved by requiring walls that may need to be moved to achieve the space requirement to: 1) be non-loadbearing walls (i.e. non-structural walls), 2) have electrical systems that can be terminated at a nearby junction box as opposed to having to be removed from the panel completely, 3) have no plumbing in them, and 4) have no HVAC in them. It is also recommended that the ceiling on both sides of the wall be at the same height and have the ceiling finishes go above the top plate, so that when the wall is removed, only minor finishing is required (e.g. applying drywall compound and paint), and the floor finishing can be easily repaired.
Note 3: It is recommended to consider acoustic measures along paths of travel to improve accessibility for individuals with hearing impairments, cognitive disabilities, or sensory sensitivities. As an example, this can be achieved by installing acoustic tiling, sound baffles, and noise-reducing materials to reduce sound reverberation and minimize echo. If possible, these considerations should be made at the design stage.
12.3.4 Area allowances for clear floor spaces
Clear floor or ground spaces to accommodate a person who uses a wheeled mobility device shall:
be constructed to:
be at least 820 mm by 1390 mm for a stationary position;
have a minimum 1800 mm turning diameter; and
be at least 1800 mm by 1200 mm by 1200 mm for a T-turn; or
Design for accessible-ready (DAR): the clear floor space shall be designed such that the clear floor space can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C). This option shall only be used if the clear floor space specified in sentence a) would lead to a loss of a living room, bedroom, or bathroom.
Note 1: It is recommended that this option only be used if the clear floor space specified in sentence a) would affect a living room, bedroom, or bathroom.
Note 2: The requirements for area allowances stipulated in CSA/ASC B652:23 provide a usable space for the highest possible percentage of people. Therefore, area allowances and space requirements are recommended to be achieved whenever possible. Within the concept of accessible-ready housing, area allowances and space requirements may affect layout options. This is because adapting space requirements may involve moving walls. At the same time, these space requirements, particularly for smaller houses, may affect the functionality and use of the space for various users, such as a bedroom, an office space, a closet, or a bathroom, all of which may benefit some occupants more than the space requirement. As a result, despite the need to relocate walls, this standard is aimed at providing provision to allow for the accessible-ready approach while making removing walls easier. This is achieved by requiring walls that may need to be moved to achieve the space requirement to: 1) be non-loadbearing walls (i.e. non-structural walls), 2) have electrical systems that can be terminated at a nearby junction box as opposed to having to be removed from the panel completely, 3) have no plumbing in them, and 4) have no HVAC in them. It is also recommended that the ceiling on both sides of the wall be at the same height and have the ceiling finishes go above the top plate, so that when the wall is removed, only minor finishing is required (e.g. applying drywall compound and paint), and the floor finishing can be easily repaired.
Note 3: The turning diameter for various equipment may exceed the requirements stipulated in this standard and in CSA/ASC B652. Power assisted wheelchairs may have a minimum turning diameter of 2100 mm, and power assisted scooters may have a minimum turning diameter of 3150 mm.
12.3.5 Area allowances for knee and toe clearances
Counters and work surfaces shall:
be installed in a manner that their removal and replacement with items meeting CSA/ASC B652 clause 4.3.3 can be conducted without any modifications to the structural, electrical, plumbing, or HVAC systems;
have the finished flooring extend to the wall behind the cabinets as to permit removal of the cabinet without having to do repairs to the finished flooring; and
where present, have the backsplash start from a height of 730 mm above the finished floor.
Note 1: For example, tile backsplash is installed such that the bottom edge is a full tile where new tiles can be added without having to replace all the backsplash. Flooring is to be installed in a manner where if the flooring is to be continued underneath the counter or work surface, a clean and smooth transition is possible.
Note 2: Cabinets, which are typically in kitchens, bathrooms, and laundry rooms have a significant impact on the functionality of the most important rooms in a house. Accessible-ready housing is intended to be more functional for more people and some effort is required to modify the features of the home. Therefore, cabinets are one area where investing design effort and foresight is worthwhile to achieve this goal. This is what this requirement is intended to achieve.
12.3.6 Headroom
Headroom clearances along a path of travel shall be as per CSA/ASC B652 clause 4.7.1, except in basements. Basements shall have a headroom clearance along a path of travel at a minimum of 2030 mm.
Note: In new construction, which is the subject of this Standard, it is desired that basement ceilings, including structural beams, HVAC ductwork, and plumbing systems are installed above the 2100 mm (and 2030 mm for doorways) level as required by the CSA/ASC B652 clause 4.7.1, and therefore complying with the requirement of this section. However, it is also understood that that is challenging for basements built with a typical 2440 mm height.
12.3.7 Protruding objects
All protrusions shall:
comply with the limitations and requirements of CSA/ASC B652 clause 4.7.2; or
be removable without affecting the integral buildings systems, i.e., structural, electrical, or mechanical systems. Minor cosmetic repairs are permitted to be required for the removal of protrusions.
Note: Protruding objects are typically either furniture, structural systems, or mechanical systems. Since furniture is already removable, this Clause is to make sure no mechanical systems or structural members are placed in a manner to cause a protrusion. Non-loadbearing elements that can be removed while causing minor cosmetic damage may be allowed (e.g., partition walls). This is intended to make sure that an occupant who is tolerant of a protrusion may require such geometry to install a linen closet (for example).
12.3.8 Floor and ground surfaces finishes
Floor and ground surfaces covering shall:
be installed in accordance with CSA/ASC B652 clause 4.6; or
be installed:
in a manner that allows their replacement to flooring complying with CSA/ASC B652 clause 4.6 without the need to repair or replace any items other than baseboards, kick plates, and the flooring itself; and
Design for accessible-ready (DAR): On the accessibility form or plans, the type of assumed floor replacement complying with CSA/ASC B652 clause 4.6 for sentence i) shall be identified.
Note: Floor and ground surface covering is typically not addressed by building codes, and their replacement typically does not require a permit from the authority having jurisdiction. These items are also a matter of taste and significantly impact the aesthetics of a home. In addition to preference, the durability of flooring type for the type of mobility aid used could be considered too. As a result, this Clause provides flexibility for the occupant to choose the floor coverings they need or desire, while providing some forethought to ensure that future occupants or their future selves, have the ability to replace the floor and ground surface coverings to comply with CSA/ASC B652 if the need arises.
12.3.9 Wall finishes
Wall finishes, surfaces, and coverings shall:
be installed in accordance with CSA/ASC B652 clause 4.6; or
be installed:
in a manner that allows their replacement to wall finishes complying with CSA/ASC B652 clause 4.6 without the need to repair or replace any items other than baseboards, kick plates, and the flooring itself; and
Design for accessible-ready (DAR): On the accessibility form or plans, the type of assumed wall finishing replacement complying with CSA/ASC B652 4.6 for sentence i) shall be identified.
Note: Wall finishes are typically not addressed by building codes, and their replacement typically does not require a permit from the authority having jurisdiction. These items are also a matter of taste and significantly impact the aesthetics of a home. As a result, this Clause provides flexibility for the occupant to choose the finishes they need or desire, while providing some forethought to ensure that future occupants or their future selves, have the ability to replace the finishes to comply with CSA/ASC B652 if the need arises.
12.3.10 Bathrooms
12.3.10.1 Bathroom(s) – general
At least one bathroom in an accessible-ready house shall be designed as an accessible-ready bathroom.
Note: As a general principle, considering that bathrooms are on average retrofitted every 15 years in Canada, having bathrooms accessible-ready seems to be an efficient and productive plan. However, this standard suggests at least one bathroom be accessible-ready. The other bathrooms are also recommended to be accessible-ready where possible.
12.3.10.2 Bathroom turning space
The turning space within the accessible-ready bathroom in an accessible-ready house shall:
comply with the requirements of clause 12.3.4; or
Design for accessible-ready (DAR): The turning space shall be designed such that it can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note 1: It is recommended that this option only be used if the turning space specified in sentence a) would affect a living room, bedroom, or bathroom.
Note 2: The requirements for area allowances stipulated in CSA/ASC B652 provide a usable space for the highest possible percentage of people. Therefore, area allowances and space requirements are recommended to be achieved whenever possible. Within the concept of accessible ready housing, area allowances and space requirements may affect layout options. This is because adapting space requirements may involve moving walls. At the same time, these space requirements, particularly for smaller houses, may affect the functionality and use of the space for various users, such as a bedroom, an office space, a closet, or a bathroom, all of which may benefit some occupants more than the space requirement. As a result, despite the need to relocate walls, this standard is aimed at providing provision to allow for the accessible ready approach while making removing walls easier. This is achieved by requiring walls that may need to be moved to achieve the space requirement to: 1) be non-loadbearing walls (i.e., non-structural walls), 2) have electrical systems that can be terminated at a nearby junction box as opposed to having to be removed from the panel completely, 3) have no plumbing in them, and 4) have no HVAC in them. It is also recommended that the ceiling on both sides of the wall be at the same height and have the ceiling finishes go above the top plate, so that when the wall is removed, only minor finishing is required (e.g., applying drywall compound and paint), and the floor finishing can be easily repaired.
12.3.10.3 Bathroom doors
The accessible-ready bathroom doors shall comply with Clauses 12.3.2.1 to 12.3.2.7.
Note: Refer to the note under Clauses 12.3.2.1 to 12.3.2.7.
12.3.10.4 Bathroom floors
The accessible-ready bathroom floors shall comply with clause 12.3.8.
Note: Floor and ground surface covering is typically not addressed by building codes, and their replacement typically does not require a permit from the authority having jurisdiction. These items are also a matter of taste and significantly impact the aesthetics of a home. As a result, this Clause provides flexibility for the occupant to choose the floor coverings they need or desire, while providing some forethought to ensure that future occupants or their future selves, have the ability to replace the floor and ground surface coverings to comply with CSA/ASC B652 if the need arises.
12.3.10.5 Bathroom wall reinforcing
The accessible-ready bathroom walls shall comply with CSA/ASC B652 clause 5.9.5.
Note 1: Wood stud wall reinforcement is typically in the form of blocking, which allows for the easier installation of grab bars, and the ability to move vanities and other bathroom fixtures to other locations to help future users optimize their preferences.
Note 2: Additional reinforcement of structural members for the installation of lifts may be considered if the location and lift specifications are known.
12.3.10.6 Bathroom lighting
The accessible-ready bathroom lighting shall be compatible with lighting fixtures that comply with the requirements of CSA/ASC B652 clause 5.9.6.
Note: Lighting solutions are personal. While some need or prefer higher lighting levels, others need or prefer much lower levels. As a result, this Clause is intended to ensure that whatever electrical lighting system is installed, it is compatible with any lighting level that the occupant desires. The lighting level required by CSA/ASC B652 clause 4.8.1 are much higher than those typically installed in homes.
12.3.10.7 Bathroom electrical
The accessible-ready bathroom electrical shall:
comply with the requirements of CSA/ASC B652 clause 5.9.8; or
have electrical conduits between a power source and the locations where GFCI receptacles need to be located to comply with sentence a) such that the installation of GFCI receptacles will not require repainting or removing of bathroom fixtures.
Note: CSA/ASC B652 clause 5.9.8 may not be compatible with some local electrical codes, and the requirements may not suit some occupants’ taste or needs. Sentence b) above is provided to ensure that future occupants who may need to make the change, can do so with minimal costs.
12.3.10.8 Bathroom luminance (colour) contrast
The accessible-ready bathroom fixtures shall be compatible to be replaced with fixtures complying with the CSA/ASC B652 clause 5.9.9.
Note: This requirement is intended to recognize that people may have individual preferences to the type of operating controls they install within their own home. These are typically easy to replace, and therefore can be replaced later.
12.3.10.9 Bathroom toilet and accessories
The accessible-ready bathroom toilet and accessories shall:
comply with the requirements of CSA/ASC B652 clause 5.9.10; or
Design for accessible-ready (DAR): The bathroom shall be designed such that it can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note: This note is the same for all aesthetic components that are typically selected by a homeowner to suit their needs and taste and are rarely regulated by the authorities having jurisdiction. Therefore, an accessible-ready option is considered appropriate with the caveat that they must not preclude a future occupant from retrofitting the item with a CSA/ASC B652-compliant clause, without significant renovation.
12.3.10.10 Bathroom grab bars
Where installed, bathroom grab bars shall meet the requirements of CSA/ASC B652 clause 5.9.11.
12.3.10.11 Bathroom sink and vanity
The accessible-ready bathroom sink and vanity shall:
comply with the requirements of CSA/ASC B652 clause 5.9.12; or
Design for accessible-ready (DAR): The bathroom, including the sink and vanity, shall be designed such that it can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note: This note is the same for all aesthetic components that are typically selected by a homeowner to suit their needs and taste and are rarely regulated by the authorities having jurisdiction. Therefore, an accessible-ready option is considered appropriate with the caveat that they must not preclude a future occupant from retrofitting the item with a CSA/ASC B652-compliant clause, without significant renovation.
12.3.10.12 Bathroom showers
The accessible-ready bathroom shower shall:
comply with the requirements of CSA/ASC B652 clause 5.9.13; or
Design for accessible-ready (DAR): The bathroom, including the shower, shall be designed such that it can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note: This note is a combination of the notes for clauses that significantly impact the space and area requirements (note under Clause 12.3.3), and those for clauses that impact the occupants’ selections based on personal preference (note under Clause 12.3.10.9). Accessible-ready is important in such situations, since without it, it may impact important and personal spaces such as a shower, loss of bathroom, or loss of another room which may not be universally preferred for various users. It should be noted that for some individuals, where space is limited, a shower may often be preferred over a bathtub.
12.3.10.13 Bathroom bathtubs
Where provided, the accessible-ready bathroom bathtub shall:
comply with the requirements of CSA/ASC B652 clause 5.9.14; or
Design for accessible-ready (DAR): The bathroom, including the bathtub, shall be designed such that it can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note 1: It should be noted that it is desirable to design and install a bathtub while keeping in mind a possible future conversion to a shower utilizing the same footprint and plumbing.
Note 2: This note is a combination of the notes for clauses that impact the space and area requirements (note under Clause 12.3.3), and those for clauses that impact the occupants’ selections based on personal preference (note under Clause 12.3.10.9). Accessible-ready is important in such situations, since without it, it may affect a shower, loss of bathroom, or loss of another room which may not be universally preferred for various users. It should be noted that for some individuals, where space is limited, a shower may often be preferred over a bathtub.
12.3.10.14 Bathroom medicine cabinets
Where provided, the accessible-ready bathroom medicine cabinets shall:
comply with the requirements of CSA/ASC B652 clause 5.9.15; or
Design for accessible-ready: The bathroom, including the medicine cabinet, shall be designed such that it can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note: This note is a combination of the notes for clauses that significantly impact the space and area requirements (note under Clause 12.3.3), and those for clauses that impact the occupants’ selections based on personal preference (note under Clause 12.3.10.9). Accessible-ready is important in such situations, since without it, it may lead to a loss of a shower, loss of bathroom, or loss of another room which may not be universally preferred for various users. It should be noted that for some individuals, where space is limited, a shower may often be preferred over a bathtub.
12.3.10.15 Bathroom storage
Where provided, bathroom storage shall:
comply with CSA/ASC B652 clauses 4.4 and 4.5; or
be removable without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note: This note is a combination of the notes for clauses that significantly impact the space and area requirements (note under Clause 12.3.3), and those for clauses that impact the occupants’ selections based on personal preference (note under Clause 12.3.10.9). Accessible-ready is important in such situations, since without it, it may lead to a loss of a shower, loss of bathroom, or loss of another room which may not be universally preferred for various users. It should be noted that for some individuals, where space is limited, a shower may often be preferred over a bathtub.
12.3.11 Kitchens
Kitchens, including floor areas, doors, floors, walls, lighting, electrical, counters, sink, storage, and appliances, shall:
comply with CSA/ASC B652 clause 5.10; or
Design for accessible-ready (DAR): The kitchen shall be designed such that it can be constructed meeting the requirements of sentence (a) without significant modifications for the structural, plumbing, or HVAC systems (see Annex C).
Note 1: As part of the development of this Standard, it is deemed accessible-ready that kitchen cabinets, counters, and fixtures may have to be replaced to meet the various differing needs of the various occupants. The goal of this Clause is to have accessible-ready kitchens designed to be flexible to allow for more cost-effective renovations, to cater to more users than a standard kitchen or accessible kitchen (i.e., compliant with CSA/ASC B652 clause 5.10).
Note 2: Kitchens are arguably one of the most important rooms in homes. Homeowners typically place a very high importance on the functionality and aesthetics of a kitchen. To avoid the prescriptive requirements of CSA/ASC B652 for kitchens, which may not be universally desirable, it is essential to incorporate accessible-ready and flexibility into the design and construction, despite the high cost of kitchen renovations. The overarching principle is that a homeowner can have a kitchen as they prefer, however forethought must be given for future users or their own future needs. Specifically, counters, which are typically in kitchens, bathrooms, and laundry rooms have a significant impact on the functionality of the most important rooms in a house. Furthermore, different counter heights (even what may be considered small differences) have a noticeable impact for different users. As a result, in keeping with the concept that accessible ready housing is intended to be more functional for more people, where some effort is required to modify the features of the home, counters are one area where it is worth investing in design effort and foresight to achieve this goal. This is what this requirement is intended to achieve.
Note 3: The design of kitchens should consider safety and convenience. Some ideas include providing counters beside appliances, placing the microwave on the counter or at counter height, the refrigerator should open away from the counter, under counter lighting, electrical outlets that are reachable, dishwasher drawers and continuous flooring and ceiling treatments.
12.3.12 Bedrooms area requirements
Bedroom floor area, floors, and lighting shall:
comply with CSA/ASC B652 clauses 5.11.1, 5.11.2 and 5.11.3; or
Design for accessible-ready (DAR): The bedroom shall be designed such that it can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note 1: Like the note under Clause 12.3.10.12, this is a combination of the notes for clauses that impact the space and area requirements (note under Clause 12.3.3), and those for clauses that impact the occupants’ selections based on taste and personal preference (note under Clause 12.3.10.9). Accessible-ready is important in such situations, since without it, it may impact important and personal spaces such as a bedroom, an office space, a bathroom, or another room which may not be universally preferred for various users.
Note 2: Reinforcement of structural members for the installation of lifts may be considered in bedrooms if the location and lift specifications are known.
12.3.13 Laundry
Laundry room area, features and appliances, doors, floor, lighting, sink, washer and dryer, folding surface, storage, and ironing board shall:
comply with CSA/ASC B652 clause 5.12; or
Design for accessible-ready (DAR): The laundry room shall be designed such that it can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note 1: Like the note under Clause 12.3.10.12, this is a combination of the notes for clauses that significantly impact the space and area requirements (note under Clause 12.3.3), and those for clauses that impact the occupants’ selections based on taste and personal preference (note under Clause 12.3.10.9). Accessible-ready is important in such situations, since without it, it may impact important and personal spaces such as a bedroom, an office space, a bathroom, or another room which may not be universally preferred for various users.
Note 2: Smart-home technology excels at helping all people live a more independent lifestyle. Automation, scheduling, and voice control enable users to easily control a host of devices—from lights and switches to climate-control systems to kitchen appliances, smart Wi-Fi video doorbell, two outdoor Wi-Fi security cameras, and a smart garage-door opener, even real-time viewing inside fridges. While it is not expected that accessible-ready housing will come with these devices, it is important to have the electrical capacity and Wi-Fi to support them.
12.3.14 Closets
Where provided, closets (including within bedrooms), shall:
comply with CSA/ASC B652 clause 5.13;
be removable without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C); or
Design for accessible-ready (DAR): The closet shall be designed such that it can be constructed meeting the requirements of sentence a) without significant modifications for the structural, electrical, plumbing, or HVAC systems (see Annex C).
Note: Like the note under Clause 12.3.10.12, this is a combination of the notes for clauses that significantly impact the space and area requirements (note under Clause 12.3.3), and those for clauses that impact the occupants’ selections based on taste and personal preference (note under Clause 12.3.10.9). Accessible-ready is important in such situations, since without it, it may affect a bedroom, an office space, a bathroom, or another room which may not be universally preferred for various users.
12.3.15 Service rooms and spaces
Where provided, a service room (i.e., a room dedicated to garbage disposal, mailboxes, or mechanical or electrical equipment) shall:
be served by a path of travel in accordance with Clause 12.3.3;
be served by a clear floor space in accordance with CSA/ASC B652 clause 4.4.2; and
have equipment controls located in accordance with Clause 10, except for items that require servicing by professionals.
Note: The requirements in CSA/ASC B652 refer to the need for a path of travel, clear floor space, and equipment control locations in accordance with the other sections of the Standard. However, since this Standard focuses on accessible-ready, all these requirements have an accessible ready equivalent, which are applicable to the service rooms and spaces. Having said that, complying with the requirements of CSA/ASC B652 for service rooms and spaces is much preferred not only from an accessibility point of view, but also to service equipment, upgrade to new technologies, or add additional technologies (e.g. solar panels inverters and batteries, backup emergency generator batteries and other equipment, etc.).
