Alberta's building code doesn't require an accessible kitchen in a house. Its kitchen rules apply only to adaptable units, which province-funded projects of 10 or more homes must provide at 1 in 10, and there the sink or cooktop counter adjusts down to 710 mm (2 ft 4 in) over an 800 mm (2 ft 7 in) wide knee space (NBC(AE) 2023, 3.8.1.1 and 3.8.4.4). For everyone else, the free CMHC Universal Design guide (2022) recommends "at least 1,800 mm of unobstructed floor space between opposing counters". Here are both sets of numbers, as of October 2026.

Key takeaways

  • Section 3.8 of the code doesn't apply to detached or semi-detached houses, houses with a secondary suite, duplexes, triplexes, townhouses or row houses, as of October 2026 (NBC(AE) 2023, 3.8.2.1).
  • In an adaptable unit, the sink or cooktop counter adjusts so its surface is at least 710 mm (2 ft 4 in) high, over a clearance 800 mm (2 ft 7 in) wide and 685 mm (2 ft 3 in) high near the front (NBC(AE) 2023, 3.8.4.4).
  • An adaptable unit's kitchen needs a 1 700 mm (5 ft 7 in) turning diameter, and its overhead cabinets must adjust down by at least 500 mm (1 ft 8 in) (NBC(AE) 2023, 3.8.4.2 and 3.8.4.4).
  • CMHC recommends at least 1 800 mm (5 ft 11 in) of clear floor between opposing counters, cabinets and appliances, measured past any protruding handles (CMHC, 2022).
  • CMHC suggests at least 610 mm (2 ft) of counter on one side of the sink and 450 mm (1 ft 6 in) on the other, with the sink not against a wall or in a corner (CMHC, 2022).
  • Calgary's secondary suite incentive set a 1.5 m (4 ft 11 in) turning diameter in the kitchen for its $7,500 accessibility top-up, but it isn't taking new applications (The City of Calgary, 2026).

Does Alberta's building code require an accessible kitchen?

Not in a house. Section 3.8, the code's barrier-free section, applies to all buildings except a short list that starts with "detached houses, semi-detached houses, houses with a secondary suite" (NBC(AE) 2023, 3.8.2.1). Even in apartment buildings, where Section 3.8 applies to common areas, the suites themselves don't need accessible kitchens.

The one exception is Alberta's own. Residential projects of 10 or more dwelling units "funded in whole or in part by the Government of Alberta" must make 1 unit in 10 adaptable (3.8.1.1.(3)). Alberta's Accessibility design guide 2024 (October 2024) adds that the count is based on all the units in the project, not just the ones the funding covers.

Who has to build what, as of October 2026:

ProjectAccessible kitchen required?Rule
Detached or semi-detached house, house with a suite, duplex, townhouseNo3.8.2.1
Apartment or condo suite, privately fundedNo3.8.2.1, 3.8.1.1
Province-funded project of 10 or more unitsYes, in 1 unit per 10 (adaptable)3.8.1.1.(3), 3.8.4.4
Any house kitchenNo accessibility rule, but cooktop clearances apply9.10.22

Note: A summary of the code's application rules, not a ruling on your project. In Calgary, the City applies the code at permit.

The cooktop rules do apply in every house. Cabinets directly above a cooktop must be at least 750 mm (2 ft 6 in) above the burners, or 600 mm (2 ft) if they're noncombustible or protected by a metal hood projecting 125 mm (4.9 in) beyond them (NBC(AE) 2023, 9.10.22.2). Lowering upper cabinets for a seated cook can't cut into that.

What does an adaptable kitchen need?

Where the code does apply, it sets these numbers for the kitchen of an adaptable unit (NBC(AE) 2023, 3.8.4.2, 3.8.4.4 and 3.8.3.20):

ElementCode minimum or rangeClause
Turning space in the kitchen1 700 mm (5 ft 7 in) diameter, unobstructed3.8.4.2.(4)
Counter section at every kitchen counterAt least 800 mm (2 ft 7 in) long, surface no higher than 865 mm (2 ft 10 in)3.8.4.4.(1), 3.8.3.20
Sink or cooktop counterAdjustable, to no lower than 710 mm (2 ft 4 in) and no higher than the counter beside it3.8.4.4.(2)
Clearance under the sink or cooktop800 mm wide; 685 mm (2 ft 3 in) high at 205 mm (8.1 in) back from the front edge; 230 mm (9.1 in) high from 280 mm (11 in) to 430 mm (1 ft 5 in) back3.8.4.4.(3)
Overhead cabinetsAdjustable in height by at least 500 mm (1 ft 8 in)3.8.4.4.(4)
Electrical receptacles400 mm to 1 200 mm (1 ft 4 in to 3 ft 11 in) above the floor3.8.4.2.(7)
Doorways in the unit850 mm (2 ft 9 in) clear3.8.4.2.(8)

Note: Code minimums for adaptable units as of October 2026, not recommendations for a house. The clearance profile leaves room for knees at the front and toes lower down.

The province's design guide reads the adjustable section as separate from the fixed counter, and says that if it's adjustable but not powered "there should be at least three (3) evenly spaced optional heights". As best practice it also suggests more than one outlet above the counter for appliances used every day, such as a microwave, air fryer or coffee pot.

How much floor space does an accessible kitchen need?

CMHC's guide puts the main number at 1 800 mm (5 ft 11 in) of unobstructed floor between opposing counters, cabinets and appliances, wherever possible (CMHC, 2022, Part Five). For a galley, it measures that 1 800 mm "in addition to any protruding handles" from appliances and base cabinets. That's wider than the code's 1 700 mm turning diameter, so a kitchen built to CMHC's aisle also holds the code's circle.

The widths that matter in a kitchen, at the same scale:

Accessible kitchen widths at the same scaleKnee space: 800 mm (2 ft 7 in); Calgary incentive: 1 500 mm (4 ft 11 in); Code circle: 1 700 mm (5 ft 7 in); CMHC aisle: 1 800 mm (5 ft 11 in)800 mm2 ft 7 inKnee space1 500 mm4 ft 11 inCalgary incentive1 700 mm5 ft 7 inCode circle1 800 mm5 ft 11 inCMHC aisle

And the code's 1 700 mm circle inside an example galley 4 m (13 ft 1 in) long, with counters 1 800 mm apart:

1 700 mm turning circle in a galley with counters 1 800 mm apart CMHC's 1 800 mm between counters holds the code's 1 700 mm adaptable-unit turning diameter with 50 mm to spare on each side. Drawn to scale.

CMHC prefers U-shaped, L-shaped and galley layouts with the sink near the stovetop, so pans slide from one to the other instead of being lifted. An island with knee room under it can be approached from all four sides. Beyond the kitchen, CMHC suggests a 1 800 mm turning circle in living spaces, a path at least 1 200 mm (3 ft 11 in) wide through them, and doorways of at least 860 mm (2 ft 10 in), ideally 920 mm (3 ft); the hallway width guide covers paths.

Where do the sink, cooktop and oven go?

CMHC's guidance for each appliance is specific, and most of it changes the plan rather than the finishes. The recommendations, with the code value where one exists:

ItemCMHC 2022 recommendationCode value for adaptable units
Counter beside the sinkAt least 610 mm (2 ft) on one side and 450 mm (1 ft 6 in) on the otherNone
Sink positionNot directly next to a wall; not in a cornerNone
Under the sinkOpen legroom, with a sloped panel hiding the plumbing800 mm wide clearance (3.8.4.4.(3))
FaucetSingle lever or hands-free, with anti-scald featuresNone
CooktopSeparate from the oven, open underneath, controls at the front so no one reaches across burnersSame clearance as the sink if it's the adjustable counter
OvenWall-mounted at a height everyone can reach, with heat-resistant landing space nearby, such as a pull-out shelf belowNone
MicrowaveOn the counter or built in like the wall ovenNone

Note: CMHC recommendations are best practice, not code requirements. The code values apply only to adaptable units in funded projects.

Separating the cooktop from the oven is the biggest layout change. A range puts the oven under the burners, which blocks the legroom a seated cook needs. A wall oven needs its own cabinet run and a landing surface beside it.

What about storage, outlets and lighting?

CMHC's guide favours drawers and pull-out shelves over deep base cabinets, continuous countertops so heavy pots slide rather than lift, and D-type pull handles in a contrasting colour. It recommends dimmable task lighting and colour or tone contrast between counters and walls, and light switches usable from a seated position.

If an adjustable-height counter is beyond the budget, CMHC suggests pre-installing the wiring and junction boxes behind the wall so an electrically adjustable counter can go in later. In an adaptable unit, outlets sit 400 mm to 1 200 mm above the floor, and controls such as switches and thermostats sit 900 mm to 1 200 mm (2 ft 11 in to 3 ft 11 in) high beside a clear floor space of 1 350 mm by 800 mm (3.8.4.2.(6) and 3.8.3.8). Those are good targets in any house, though nothing requires them there.

Does Calgary fund accessible kitchens?

Calgary's Secondary Suite Incentive Program offered up to an additional $7,500 for suites accessible to people with common mobility issues (The City of Calgary, 2026). Its accessibility standard asked for a minimum 1.5 m (4 ft 11 in) turning diameter in the living area, kitchen and bedroom, a 920 mm (3 ft) path of travel throughout, and 850 mm (2 ft 9 in) doorways fully open. As of October 2026 the City's page says applications made after 23 June 2026 went on a waitlist and it's no longer accepting new ones.

See the kitchen at full size before the cabinets are ordered

A 1 800 mm aisle and a 1 700 mm circle are hard to judge from a drawing. At 1to1 Plans Calgary, your plan is lit at full size on a walkable LED floor with room names and dimension lines, and kitchen elevations go up on a wall-size screen behind it, so you can check counter heights and the knee space under the sink against the plan.

If your designer draws the turning circle on the plan, it shows on the floor at full size. Changes go onto the floor on the spot, and you keep the session recording. Send plans as a PDF or DWG at least three days ahead. Sessions are quoted for the plan by its size, the quote is free, and there's nothing to pay at booking (pricing). Book a session, see how the studio helps homeowners, or read the other room size guides.

Questions

How wide should an accessible kitchen be?

An accessible kitchen should have at least 1 800 mm (5 ft 11 in) of clear floor between opposing counters, cabinets and appliances, CMHC's Universal Design guide recommends. Alberta's code asks for a 1 700 mm (5 ft 7 in) turning diameter in the kitchen of an adaptable unit.

What height is an accessible kitchen counter in Alberta?

An accessible kitchen counter in an Alberta adaptable unit has a section no higher than 865 mm (2 ft 10 in), and the sink or cooktop counter adjusts down to no lower than 710 mm (2 ft 4 in), under 3.8.3.20 and 3.8.4.4 of the National Building Code, 2023 Alberta Edition.

Does a new house in Alberta need a wheelchair accessible kitchen?

A new house in Alberta doesn't need a wheelchair accessible kitchen, as of October 2026. Section 3.8 of the code exempts detached and semi-detached houses, houses with a secondary suite, duplexes, triplexes, townhouses and row houses.

How much knee space goes under an accessible sink?

An accessible sink in an Alberta adaptable unit needs a clearance under it at least 800 mm (2 ft 7 in) wide and 685 mm (2 ft 3 in) high at 205 mm back from the front edge, stepping down to 230 mm (9.1 in) high from 280 mm to 430 mm back.

How much counter should be beside an accessible sink?

CMHC's Universal Design guide suggests at least 610 mm (2 ft) of counter on one side of an accessible sink and 450 mm (1 ft 6 in) on the other. It also advises against placing the sink right next to a wall or in a corner.
