Yes, you can build a secondary suite in Airdrie if your home meets the City's Land Use Bylaw rules. You need a $300 development permit first, then a basement building permit.
Airdrie also requires three on-site parking stalls: two for the house and one for the suite. However, neighbours receive formal notice only when the suite is a discretionary use.
Can I Build a Secondary Suite in Airdrie?
Yes, if the home is a single detached dwelling and the land use district allows suites. The district must list secondary suites as a permitted or discretionary use.
First, Titan Pro Developer checks these conditions before any design work starts:
- A single detached home (townhouses do not qualify; semi-detached suites are discretionary since 2024)
- A land use district that lists secondary suites as a permitted or discretionary use
- No other suite, bed and breakfast, child care facility or supportive housing on the lot
- Three on-site parking stalls, because on-street parking does not count toward a suite application
Do I Need a Development Permit for a Secondary Suite in Airdrie?
Yes, every Airdrie secondary suite needs a development permit before a basement building permit. The $300 permit takes about 2 to 4 weeks, according to City of Airdrie's secondary suites page (September 2026).
Then applicants file both permits online through myAIRDRIE, and Titan Pro's secondary suite development service manages both filings.
- Confirm zoning, use type and parking on your lot.
- Submit the accessory suites development permit through myAIRDRIE.
- Wait about 2 to 4 weeks for a decision on a complete application.
- Apply for the basement building permit once the development permit issues.
- Build to the National Building Code (Alberta Edition) and the Safety Codes Act.

How Many Parking Spaces Does an Airdrie Secondary Suite Need?
Airdrie requires three on-site stalls: two for the main house and one for the suite. On-street parking never counts toward that total.
Since the 2024 bylaw, suites need one stall regardless of bedrooms, according to Involve Airdrie's bylaw summary (December 2024). Previously, the rule scaled with bedroom count.
"Check parking before you pay for drawings. Every stall must sit on your lot, and the street never counts." — Jack Cabrera, Titan Pro Developer Limited
Can My Neighbour Object to a Secondary Suite in Airdrie?
It depends on the use type. For a permitted use, the City must approve a compliant application, so neighbours have little room to object.
However, anyone affected by a discretionary approval can appeal within 21 days. Alberta's Municipal Government Act sets that window, according to Rocky View County's appeal guide (February 2026).

Are Secondary Suites Allowed in All Airdrie Neighbourhoods?
No, because suite rights depend on each parcel's land use district. The City's address and land use map shows the district for any lot.
| Property situation | Use type | Neighbour notice |
|---|---|---|
| Single detached home in a permitted district | Permitted | None; City approves if compliant |
| Semi-detached home | Discretionary | Notice and 21-day appeal window |
| Cul-de-sac lot | Discretionary | Notice and 21-day appeal window |
However, zoning can change, so confirm the district before you buy plans. Titan Pro Developer holds an Airdrie licence and can check a parcel first.
What Changed in Airdrie's Suite Bylaw for 2026?
Bylaw B-30/2024, adopted December 17, 2024, set the current rules for suites in Airdrie:
- One parking stall per suite, regardless of suite type
- No minimum lot dimensions for secondary suites
- Front entries and shared indoor landings allowed
- Home businesses allowed on the same site when parking requirements are met
- Semi-detached and cul-de-sac suites classed as discretionary uses
Bylaw B-01/2026 proposes further changes to entries, walkways and cul-de-sac wording. A City committee recommended it on April 14, 2026.
| 📈 Trend Watch: The City reports a significant rise in accessory suite applications and projects further growth. |

Airdrie Secondary Suite FAQ
How much does a secondary suite permit cost in Airdrie?
The development permit costs $300. A variance request adds a fee but runs under the same application. Because the City lists building permit fees separately, confirm that amount before you budget.
What building code requirements apply to Airdrie secondary suites?
Suites must follow the National Building Code (Alberta Edition) and the Safety Codes Act. That applies to new construction and to conversions of existing developed basements into legal suites.
How long does the Airdrie secondary suite application take?
The development permit typically takes 2 to 4 weeks after a complete submission. However, incomplete applications restart that clock. The City's secondary suites dashboard also shows live permit status and processing times.
Where do I apply for a secondary suite permit?
Apply online through your myAIRDRIE account. File the accessory suites development permit first. Then submit the basement building permit application once the first approval is in hand.
Can I get a variance if my lot misses a standard?
Yes. The development authority may relax a standard in two cases. First, the variance must not harm neighbouring amenities. Second, it must be specific to your property.
Does an Airdrie secondary suite need a separate entrance?
Yes. The City lists a separate entrance as one of five required elements. The other four are living, cooking, sleeping and sanitation facilities inside the suite.
