As of October 2026, the Town of Canmore charges $10.00 per $1,000 of construction cost for a residential building permit, plus a 4% Safety Codes Council fee and a review fee of $46 to $135 (Town of Canmore, 2026 Master Fee Schedule). The bigger difference is the order: the Town won't accept a building permit until any development permit is approved, and its Land Use Bylaw requires one for every new house that doesn't include a suite.
Key takeaways
- As of October 2026, a Canmore residential building permit costs $10.00 per $1,000 of construction cost, with a $100 minimum, plus the 4% levy and a review fee (Town of Canmore, 2026 Master Fee Schedule).
- Canmore's Land Use Bylaw requires a development permit for "All proposed Detached Dwellings which do not include an Accessory Dwelling Unit" (Town of Canmore, Land Use Bylaw 2018-22, section 1.8.0.3).
- An attached suite in Canmore can't exceed 40% of the building's floor area or 80 m² (861 sq ft), whichever is less, and a detached suite tops out at 60 m² (646 sq ft) (Land Use Bylaw, section 8.4).
- From March to August 2026, Canmore's development permits for new houses and suites averaged 48 days to a decision against a 42-day target (Town of Canmore, permit review times).
- In the R1 district, a house on a lot under 930 m² can't exceed 325 m² (3,498 sq ft) of floor area, though an attached suite doesn't count (Land Use Bylaw, section 3.1.3.11).
Why does Canmore put the development permit first?
Because a new house without a suite is a discretionary use in Canmore's main detached-house districts. In R1 and R1A, "Detached Dwelling (with an Accessory Dwelling Unit)" is a permitted use, while a plain "Detached Dwelling" is discretionary (Land Use Bylaw, sections 3.1 and 3.2). Section 1.8.0.3 then requires a development permit for every detached house without a suite.
The building permit page is firm about the sequence: the Town "will not accept Building Permit applications" for projects missing a needed development permit (Town of Canmore, building permits). Here's what needs what, as of October 2026:
| Project | Development permit | Building permit |
|---|---|---|
| New house with a suite, under 500 m² of floor area | Not if it's a permitted use, fully compliant and outside the Steep Creek Hazard overlay | Yes |
| New house without a suite | Yes, always | Yes |
| Attached or detached suite | Not if it meets every rule; otherwise yes ($178) | Yes |
| Accessory building in a residential district | Not if it meets the bylaw | Yes |
| Addition | Not for an addition to a permitted, compliant house under 500 m² | Yes |
| Deck or balcony | Not on the exempt list; the fee is $178 | Yes |
Note: From Land Use Bylaw 2018-22, sections 1.8 and 1.9, office consolidation with amendments in force to 30 June 2026. A house or addition in the Steep Creek Hazard Development Overlay always needs one.
Calgary, by contrast, needs a development permit for a backyard suite every time (The City of Calgary, backyard suites). Canmore exempts a compliant one.
What does a building permit cost in Canmore in 2026?
Construction cost sets the fee, counting labour, fixtures and materials. These are the 2026 residential lines:
| Item | 2026 fee |
|---|---|
| Building permit, residential | $10.00 per $1,000 of construction cost, $100 minimum |
| Safety Codes Council fee | 4% of the building permit, $4.50 minimum, $560 maximum |
| Review fee, short (interior renovations, windows, demolition) | $46 |
| Review fee, standard (where a development permit was issued) | $98 |
| Review fee, top tier (house or duplex with no development permit, or over 499 m²) | $135 |
| Development permit, house or duplex | $358 plus $167 per unit |
| Development permit, accessory dwelling unit or building | $178 |
| Development permit, addition | $237 plus $1.45 per m² |
| Animal-proof waste container cash-in-lieu | $2,598 per new or additional dwelling unit |
Note: From the 2026 Master Fee Schedule. Building or developing before a permit is issued doubles the fee. Ask whether the waste container charge applies to your project.
That last line is unusual. The fee schedule files it under cash-in-lieu, next to parking cash-in-lieu.
How do Canmore's fees compare with Calgary's?
Close on houses, far higher on additions. Calgary charges $112 plus $10.14 per $1,000 for a new house and flat fees for alterations. Here's each with the levy, before Canmore's review fee:
| Project | Canmore | Calgary |
|---|---|---|
| Deck valued at $20,000 | $208.00 | $205.92 |
| Basement development valued at $40,000 | $416.00 | $333.84 |
| Addition valued at $480,000 | $4,992.00 | $1,302.08 |
| New house valued at $2,000,000 | $20,560.00 | $20,952.00 |
Note: From Canmore's fee schedule and Calgary's 2026 schedule. Both cap the levy at $560.
The $480,000 and $2,000,000 values are close to the 2026 averages declared on Canmore's addition and house permits, shown further down. For how Calgary's fees and timelines work, see the Calgary building permit guide.
What are the rules for suites in Canmore?
Canmore calls a suite an accessory dwelling unit, attached or detached, and allows one per house. Section 8.4 of the Land Use Bylaw sets the limits:
| Rule | Attached suite | Detached suite |
|---|---|---|
| Maximum size | 40% of the building's floor area or 80 m² (861 sq ft), whichever is less | 60 m² (646 sq ft) |
| Basement exception | Up to 50% of a one-storey house's floor area | Not applicable |
| Height | 0.3 m (1 ft) extra possible for a new house with a basement suite | 5.5 m (18 ft) one storey, 6.0 m (19 ft 8 in) with a loft, at roof slopes of 2:12 or more |
| Setbacks | The house's | 1.5 m (4 ft 11 in) rear, 1.0 m (3 ft 3 in) side, never in the front yard |
| Loft | Not applicable | Up to 40 m² (431 sq ft) and 80% of the floor below, only on lots with a lane and a street or two streets |
Note: From Land Use Bylaw 2018-22, sections 8.4.1 to 8.4.3. A detached suite with a flatter roof is capped at 4.0 m (13 ft 1 in) for one storey or 5.5 m with a loft.
A suite can't be used as a tourist home, a B&B or visitor accommodation (8.4.1.1). It runs off the house's water and sewer connection, can't have a rooftop terrace, and parking on a lot with a lane has to come off the lane. At least 40% of the front yard must be landscaped.
Canmore's detached cap of 60 m² is small next to Cochrane's 80.0 m². For layouts at that scale, see the backyard suite guide; for a basement suite, the legal basement suite guide.
What else does a new house in Canmore need?
Two rules shape the drawings early. First, a size cap: in R1, residential buildings can't exceed 325 m² (3,498 sq ft) of floor area on a lot under 930 m², or 0.35 times the lot area on a bigger one. An attached suite and basement space with a ceiling less than 1.2 m above grade don't count (Land Use Bylaw, section 3.1.3.11).
Second, the Green Building Regulations, which skip suites and accessory buildings. Every new house must engage a Certified Energy Advisor before the building permit is issued, and the Town's target is an EnerGuide result at least 10% better than the reference house (section 10.3.1). Miss the paperwork or the target before occupancy and you post a refundable security, set at $4.00 per $1,000 up to $20,000 in the fee schedule.
How long does a permit take in Canmore?
Canmore publishes review times every month. For decisions from March to August 2026, updated on 15 September 2026 (Town of Canmore, permit review times):
| Permit | Target | Within target | Files | Average days |
|---|---|---|---|---|
| Development permit, new house, duplex or suite | 42 days | 45% | 11 | 48 |
| Development permit, accessory work, renovation or addition | 35 days | 80% | 5 | 37 |
| Building permit, new house, duplex or suite | 35 days | 82% | 11 | 29 |
| Building permit, addition or alteration | 35 days | 91% | 23 | 22 |
| Building permit, accessory building or deck | 35 days | 100% | 32 | 14 |
Note: Calendar days, including time waiting on the applicant. Development permits count to a decision, building permits to issue. The 21-day appeal period isn't included.
The building permit page warns that review "can take up to six weeks". Inspections run on Tuesdays and Thursdays, with at least two business days' notice. A finished building also needs an Occupancy Certificate before anyone moves in. Development permits add a notice posted on site for 10 days during review (Town of Canmore, development permits).
How much building does Canmore permit?
The Town posts a monthly summary. The August 2026 report shows these residential permits for January to August (Town of Canmore, August 2026 building permit summary):
| Residential permit type | Jan to Aug 2026 | Average declared value |
|---|---|---|
| Detached dwelling or duplex | 14 | $2,033,771 |
| Accessory dwelling unit | 3 | $31,667 |
| Addition | 11 | $478,909 |
| Deck | 33 | $21,591 |
Note: Totals divided by permits. Values are the construction cost applicants declared, not sale prices.
Only three suite permits in eight months, at about $32,000 each.
Where does a full-size walkthrough fit?
Before the development permit, while the floor area is still flexible. Under a 325 m² cap, a 60 m² detached suite and a 40 m² loft, a plan that's slightly too big gets cut, and it's better that you choose what goes.
At the 1to1 Plans Calgary studio in northeast Calgary, plans are lit at full size inside an LED floor you walk across, with room names and dimension lines. Each storey, a loft included, is walked on its own. Movable walls and furniture show how a small kitchen and bedroom fit, and each change shows on the floor during the session, which is recorded for you.
Your plan gets its own quote, and quoting is free; see pricing. Book a session, or check room sizes for code minimums first. Closer to Calgary, see the Airdrie guide or, for acreages, the Rocky View County guide.
