Legal Basement Suites in Airdrie
A legal secondary suite can help pay your mortgage, house family, or add lasting value to your home. We build them properly — fully permitted, code-compliant, and inspection-ready — so your suite is an asset, not a liability
Why suites?
Why Airdrie homeowners are building basement suites
Secondary suites are one of the fastest-growing home investments in Airdrie. The City's own numbers tell the story: applications have climbed steeply year over year, and hundreds of suites are now built across town with many more under construction. The reasons are simple — rental income to offset a mortgage, a private space for aging parents or adult kids, and a meaningful boost to property value.
But a legal suite is very different from a standard basement finish, and the difference matters.
Legal vs illegal
What makes a basement suite legal in Airdrie?
An unpermitted suite can be ordered shut down, fined, and flagged at resale. To be a recognized legal secondary suite in Airdrie, your project must meet specific requirements. A secondary suite must include five distinct elements: a separate entrance, and its own cooking, living, sleeping, and bathroom facilities. On top of that:
- It must be in a single detached home (suites aren't permitted in duplexes or townhouses).
Your property's land use district must allow a secondary suite as a permitted or discretionary use. - Parking must be provided — two spaces for the main home plus additional spaces for the suite.
- The build must meet National Building Code (Alberta Edition) requirements for egress, fire separation, ceiling height, smoke/CO alarms, and ventilation.
We know these rules — and we design your suite to satisfy them from day one.
What's involved in the build
Building a suite to code
A compliant suite involves details a standard finish doesn't:
- Egress & window wells — bedrooms need proper egress windows and window-well depths (many existing wells need modification).
- Fire separation — rated separations and self-closing solid-core doors between the suite and the main dwelling.
- Interconnected smoke & CO alarms — hardwired, battery-backed, and interconnected across both dwellings.
- Independent heating & ventilation — typically a separate furnace or an alternate heat source with proper ventilation, backed by heat-loss calculations.
- Licensed electrical & plumbing — these trades must be done by qualified contractors (homeowners can't legally DIY them in a suite). Our trades are fully qualified.
The Permit Path
The Airdrie suite permit process — handled for you
Building a legal suite in Airdrie is a two-permit process, and we manage both:
- Accessory-suite development permit — submitted first, through the City's planning process. This confirms your property is allowed to have a suite.
- Basement building permit — once the development permit is approved, we apply for the building permit to construct it to code.
We prepare the drawings, submit the applications, and coordinate the inspections — so you're not deciphering bylaws or standing at the permit counter.
Basement suite FAQs
Is a basement suite worth it?
Is a basement suite worth it?
For many Airdrie homeowners, a legal suite pays for itself over time through rental income and adds resale value as a recognized, permitted living space. We'll give you a clear, itemized quote so you can weigh the investment against the return.
Do I need a permit for a basement suite in Airdrie?
Yes — both a development permit (for the accessory suite) and a building permit. We handle the entire process.
How long does suite approval take?
The development permit typically takes a few weeks to process once a complete application is submitted; construction time is on top of that. We'll map out the full timeline for you.
Can any house in Airdrie have a suite?
No — it must be a single detached home in a land-use district that allows secondary suites, with adequate parking. We confirm your eligibility before you commit.
What if I already have an unpermitted suite?
We can assess what's there and bring it up to code so it can be properly permitted.
