Calgary has 26,000+ registered legal secondary suites. Here's how to check any basement suite against the City's registry — and why it matters for your safety and your lease.
Calgary is one of the few cities in Canada where you can actually look up whether a basement suite is legal. The City of Calgary's public Secondary Suite Registry lists more than 26,000 registered suites across 195 communities — over 5,500 of them completed in just the last year.
And yet thousands of Calgary renters are living in suites that were never permitted, never inspected, and never registered. Most of them have no idea.
Here's how to check any suite in about thirty seconds, what "legal" actually means, and what it means for you if the suite you're looking at isn't on the list.
What makes a basement suite "legal" in Calgary?
A legal secondary suite isn't just a basement with a bed in it. To be registered, a suite has to go through the City's permit process and pass safety inspections. The requirements exist for one reason: a below-grade home has different fire and safety risks than the floors above it.
At a high level, a registered suite has been checked for things like:
- A safe second way out — properly sized egress windows or exits
- Working, interconnected smoke and carbon monoxide alarms — if an alarm triggers upstairs, it sounds in the suite too
- Proper ceiling heights, heating, and ventilation for a living space
- A permitted kitchen and bathroom — built with inspections, not around them
Suites that pass get a registration number and a numbered registry sticker, usually displayed near the suite's entrance. The City's current requirements are on calgary.ca's secondary suites page.
Why it matters — for renters
An unpermitted suite isn't automatically a death trap, but you have no way of knowing what's behind the drywall. Renting one carries real risks:
- Safety. No inspection means no one has verified the escape routes, alarms, or wiring. In a basement fire, minutes matter.
- You can lose your home. If the City receives a complaint about an illegal suite, the owner can be ordered to stop renting it — and you're the one moving out mid-lease.
- Insurance headaches. Tenant insurance claims get complicated when the unit itself wasn't legal to rent.
- No leverage. Landlords running unpermitted suites are less likely to follow the rest of Alberta's tenancy rules, too.
A registered suite tells you the landlord did things properly when it counted.
How to check a suite in 30 seconds
Option 1 — the City's registry. Go to secondarysuites.calgary.ca and search the address. Every registered suite in Calgary is in there, with its community and registration details. It's free and public.
Option 2 — look for the Legal Suite badge on Rentably. We check every Calgary basement-suite listing against the City's registry automatically. When the address matches, the listing shows a green Legal Suite badge — the same house-and-checkmark icon the City uses — in search results and on the listing page, along with the permit number and completion date. Click it and it takes you straight to the City's registry to verify for yourself.
No badge? The address didn't match the registry. That's not automatic proof a suite is illegal — a brand-new suite or an address formatting quirk can miss a match — but it's your cue to ask the landlord directly: "Is the suite registered with the City? What's the registration number?" A landlord who did it right will love that question.
You can browse basement suites for rent in Calgary — listings that match the registry show the badge front and centre.
Renting the suite: what to look for in person
Even with a registered suite, do a quick check at the viewing:
- Find the registry sticker — typically near the suite entrance.
- Check the egress window in the bedroom — could you actually climb out of it?
- Test a smoke alarm — and ask whether the alarms are interconnected with upstairs.
- Ask who lives up there — in most cases the owner lives in the other unit, which usually means faster repairs and a quieter arrangement.
For landlords: registration is the selling point
If you own a suite in Calgary, registration isn't just about avoiding bylaw complaints — it's marketing. Renters are getting smarter about this, and a registered suite:
- Stands out in search. On Rentably your listing gets the Legal Suite badge automatically once your address matches the registry — no setup, no fee.
- Justifies your rent. "Registered legal suite" is one of the few claims in a rental ad a renter can independently verify in seconds.
- Protects you. One complaint about an unregistered suite can end your rental income overnight.
If your suite isn't registered yet, start at the City's secondary suites page — it walks through permits, inspections, and current programs. Once you're in the registry, list your suite on Rentably and the verification shows up on its own.
The bottom line
Calgary gave renters a rare gift: a public, searchable answer to "is this suite legal?" Use it. Check the registry, look for the badge, and ask the question at the viewing.
