A medical clinic layout in Alberta has to fit the building code's own rules for physician clinics. As of September 2026, doorways on the barrier-free path to the clinic must be at least 915 mm (3 ft) clear, with power door operators, and the main waiting area needs a 1 700 mm (5 ft 7 in) turning space (NBC(AE) 2023, 3.8.5). One exam room in five needs both the wider door and the turning space; the code sets no minimum exam room size.
Key takeaways
- Every doorway on the barrier-free path to a physician clinic needs at least 915 mm (3 ft) of clear width, and every door on that path needs a power door operator (NBC(AE) 2023, 3.8.5.2).
- The main waiting area needs an open space at least 1 700 mm (5 ft 7 in) across for a wheelchair user to turn (NBC(AE) 2023, 3.8.5.2).
- One exam room in five, or part of five, needs a 915 mm door and a 1 700 mm turning space, so a clinic with six exam rooms needs two (NBC(AE) 2023, 3.8.5.3).
- A clinic that reprocesses instruments needs clean and dirty areas physically separated and two adjacent sinks big enough to submerge the largest item (College of Physicians & Surgeons of Alberta, 2022, 2.2.1 and 2.2.2).
- In a medical office, one water closet can serve both sexes when the occupant load is 10 or fewer, and up to 25 people of each sex need one for each sex (NBC(AE) 2023, 3.7.2.2).
- Calgary's 85 Medical Misc. permits in 2025 declared a median of $132,500, which sets the permit fee and understates the real cost (The City of Calgary, open data).
What does Alberta's building code require in a physician clinic?
Subsection 3.8.5 of the National Building Code, 2023 Alberta Edition (second printing, in force since 17 August 2026) adds five rules to the barrier-free rules every commercial building gets. It covers physician clinics and offices whose services come from physicians registered with the College of Physicians & Surgeons of Alberta (NBC(AE) 2023, Division A, 1.4.1.2).
The subsection as a checklist:
| Where | What the code asks | Clause |
|---|---|---|
| Doorways on the barrier-free path to the clinic | At least 915 mm (3 ft) clear with the door open | 3.8.5.2.(1) |
| Doors on that path | A power door operator that opens the door in the direction of travel | 3.8.5.2.(2) |
| Main waiting area | An open turning space at least 1 700 mm (5 ft 7 in) across | 3.8.5.2.(3) |
| Main reception area and at least one exam or treatment room | An assistive listening system | 3.8.5.2.(4) |
| One exam room in five, or part of five | A 915 mm doorway and a 1 700 mm turning space | 3.8.5.3.(1) |
| One treatment room in five, or part of five | The same doorway and turning space | 3.8.5.3.(2) |
| Those accessible rooms, if they have a sink | One accessible lavatory | 3.8.5.3 |
Note: Code minimums as of September 2026, not recommended sizes. The City of Calgary reviews your drawings against them.
Three differences matter before you sign a lease. Other barrier-free doorways need only 850 mm (2 ft 9 in) (NBC(AE) 2023, 3.8.3.6). The general power door rule skips a tenant's own suite door (Note A-3.8.2.7.(1)(b)), while the clinic rule covers every door on the path. And in a building of two storeys or fewer, a clinic above or below the entrance floor needs a barrier-free path where other tenants often don't (NBC(AE) 2023, 3.8.2.3).
The general rules still apply. The barrier-free path is at least 1 000 mm (3 ft 3 in) wide (3.8.3.2; see hallway widths), and a waiting room with 2 to 99 fixed seats needs 2 wheelchair spaces (Table 3.8.2.3). Unless those doors open automatically, their controls go clear of the door swing and within 1 500 mm (4 ft 11 in) of it (3.8.3.6), so leave wall space beside each door.
How big should an exam room be?
Alberta sets no minimum size for a medical exam room. The code fixes only what one room in five must hold: a 915 mm (3 ft) doorway and a 1 700 mm (5 ft 7 in) open turning space. Sizes quoted elsewhere are design choices, not Alberta rules.
The circle has to stay open, so furniture goes around it:
If that room has a sink, it must be an accessible lavatory: a rim no higher than 865 mm (2 ft 10 in), a clear floor space 800 mm (2 ft 7 in) by 1 350 mm (4 ft 5 in) in front, and its centre line at least 460 mm (1 ft 6 in) from a side wall (NBC(AE) 2023, 3.8.3.16). In a walk-in clinic, lay the waiting room chairs out around the 1 700 mm circle, not through it.
How should a clinic plan its reprocessing area?
If you sterilize reusable instruments on site, the reprocessing area shapes the whole plan. The College of Physicians & Surgeons of Alberta (CPSA) requires physicians in independently operated clinics to follow its device requirements, in effect since January 2022 (CPSA device requirements, 2022). Services that need CPSA accreditation follow separate rules. Their section 2 matches Alberta Health's 2019 standards, which bind Alberta Health Services and its contractors and which Alberta Health recommends for private clinics (Alberta Health device standards, 2019).
The layout rules in section 2, as of September 2026:
| Requirement | What it means for the plan | Clause |
|---|---|---|
| A designated reprocessing area | Apart from patient care and used only for reprocessing | 2.1 |
| Clean and dirty areas physically separated | Walls or partitions; spatial separation with one-way flow only in existing clinics that can't build them | 2.2.1 |
| Two adjacent sinks | Big enough to submerge the largest item; existing smaller clinics may use one sink and a rinsing basin | 2.2.2 |
| Hand hygiene stations | At every entrance and exit, and within the area | 2.2.3 |
| Cleanable surfaces | Intact, cut-resistant, non-porous and without seams | 2.2.4 |
| Restricted access | Limit who can enter the area | 2.2.5 |
| One-way workflow | Laid out so instruments move from dirty to clean | 2.2.6 |
Note: CPSA clause numbers, shared with Alberta Health's standards. Planning requirements, not a design; the CPSA's infection control program takes questions.
Two rules reach beyond the room. Used instruments travel in covered, leak-proof containers, apart from clean ones (CPSA 5.4 and 5.5), and reprocessed instruments can't be stored in open corridors, in patient rooms, on the floor or under sinks (9.1.4). Put the route from each exam room to the dirty side, and the clean shelf, on the first sketch.
Alberta Health also allows a way out: send reprocessing out or use single-use devices (Alberta Health, 2019). Dental offices answer to a different college; see the dental office layout guide.
How many washrooms does a medical clinic need?
The code counts water closets from the occupant load, and it gives medical offices as an example of a business and personal services occupancy, Group D (NBC(AE) 2023, Note A-3.1.2.1.(1)).
The occupant load is the number of people the clinic is designed for, but not less than Table 3.1.17.1 gives unless you can show fewer will use it (NBC(AE) 2023, 3.1.17.1). The table has no row for clinics or waiting rooms. It lists offices at 9.30 m² (100 sq ft) per person and personal services shops at 4.60 m² (50 sq ft), and your designer picks the rate and shows it to the City.
Water closets then follow Table 3.7.2.2.-B, with the load split evenly between men and women unless you can show otherwise (NBC(AE) 2023, 3.7.2.2):
| Occupant load | Water closets |
|---|---|
| 10 or fewer people in total | 1, shared by both sexes |
| 1 to 25 people of each sex | 1 for each sex |
| 26 to 50 people of each sex | 2 for each sex |
| Over 50 people of each sex | 3 for each sex, plus 1 for each further 50 |
Note: Code minimums as of September 2026. Your designer's occupant load decides which row applies.
Where washrooms are provided on a storey that needs a barrier-free path, one must be a universal washroom (NBC(AE) 2023, 3.8.2.8) with its own 1 700 mm turning space (3.8.3.13). A room with one water closet needs a full-height door that locks from inside (3.7.2.2). The barrier-free bathroom guide covers the universal washroom in detail.
What permits does a clinic fit-out need in Calgary?
Most clinic fit-outs need a building permit. As of September 2026, the City of Calgary asks for one when you alter walls, structural or not, or are the first tenant in a new building (The City of Calgary, 2026). A change of business that changes the code classification or occupant load can need one even without construction. Painting and furniture alone need none. Each trade contractor pulls separate permits for electrical, plumbing, gas and HVAC.
A development permit comes first if you change how the space is used, and the building permit waits for it. Medical offices appear on the City's permit form under personal service, office and business, and an architect or engineer may need to design and inspect the work. Alberta Health Services must review some businesses, and the City's examples, such as restaurants and daycares, don't include clinics.
Fees and timelines, as the City publishes them:
| Approval | Fee | Typical time |
|---|---|---|
| Development permit, permitted change of use | $190 | 5 business days |
| Development permit, discretionary use or with a relaxation | $594 plus $30 advertising ($624) | 10 to 12 weeks |
| Building permit, interior renovation | Set by construction value | 21 to 49 days |
Note: The City's figures as of September 2026, not quotes; timelines depend on how complete the application is. If the building makes barrier-free access hard, the City points you to Alberta Municipal Affairs for a relaxation.
What did medical fit-outs in Calgary declare in 2025?
Here's what the three medical permit classes declared in 2025:
| Permit type | Permits | Median declared value |
|---|---|---|
| Medical, miscellaneous | 85 | $132,500 |
| Medical office | 33 | $80,000 |
| Clinic | 14 | $72,000 |
Source: City of Calgary building permits open data, permits issued in 2025 excluding cancelled ones, retrieved 2026-09-25. The median is of the construction value declared on the permit application. It isn't a quote and usually runs below what the work really costs. New homes and commercial work pay permit fees on this value; most home alterations pay a flat fee.
Medical Misc. is the busiest class: 85 permits at a median of $132,500, against $80,000 for medical offices and $72,000 for clinics. A declared value is the applicant's own figure: it sets the permit fee and usually runs below what the work costs, so read these medians as a floor. Dental offices file under the same classes.
Walk the patient path at full size before you build
At the studio, your plan is lit at full size on a walkable LED floor with room names and dimension lines. If your designer draws the turning circles, you can stand in the waiting room and see what they leave for chairs.
Walk the patient's route: entrance, reception, waiting area, accessible exam room. Then walk a used tray from an exam room to the dirty side and on to clean storage, and check it never doubles back. Freestanding walls and chairs stand in for partitions and seating, changes go onto the floor on the spot, and you keep the session recording for staff who couldn't come.
Send plans as a PDF or DWG at least three days ahead; a clinic too big for the floor is walked a wing at a time. Commercial sessions are quoted by the size of the space (get a quote). Book a session, or see how architects and designers use the studio. More commercial layout guides cover other businesses.
Questions
What is the minimum exam room size in Alberta?
Alberta sets no minimum floor area for a medical exam room, as of September 2026. The building code's only exam room rule covers one room in every five, or part of five. That room needs a doorway at least 915 mm (3 ft) clear and an open 1 700 mm (5 ft 7 in) circle for a wheelchair to turn in (NBC(AE) 2023, 3.8.5.3).
Do Alberta's physician clinic rules apply to a walk-in clinic?
A walk-in clinic where physicians registered with the College of Physicians & Surgeons of Alberta see patients falls within the wording of Subsection 3.8.5, which covers physician clinics and offices. The City of Calgary applies the code at permit review, so raise it early if your space mixes physicians with other providers.
Does a medical clinic on the second floor need an elevator?
A physician clinic on a floor above or below the entrance needs a barrier-free path of travel in Alberta, even in a building of two storeys or fewer, where other tenants are often exempt (NBC(AE) 2023, 3.8.2.3). Before you lease upstairs, check for an elevator or room for a lift.
Do I need a separate reprocessing room in a medical clinic?
A physician clinic in Alberta that reprocesses reusable devices needs a designated reprocessing area, apart from patient care and used for nothing else, with clean and dirty areas physically separated (CPSA, 2022, 2.1 and 2.2.1). Only existing clinics that can't build walls may use spatial separation instead.
Alberta Health's standards name two alternatives: sending reprocessing out, or using single-use devices.
