Basement & Backyard Suites in Cochrane, Alberta
Suites already carry Cochrane's rental market — 1,738 of them against 212 purpose-built units. But every suite here is discretionary, and the Town can refuse one for clustering. The real rules.
Cochrane has the clearest demand case in the region — private suites already make up the bulk of its rental supply — but a suite here is always a discretionary approval, and the Town can turn one down if a block already has too many. There’s no grant.
HouseLyft helps homeowners in Cochrane, Alberta work out what their lot legally permits, what a suite will cost to build, what it should earn, and which programmes actually apply — then connects them with a vetted builder.
Cochrane makes an unusually strong case for a suite on the demand side — and an unusually careful one on the approval side. Both are worth understanding before you build.
The demand case is structural
Two numbers tell it. First, Cochrane’s rental market already runs on suites: about 1,738 secondary rental units against just 212 purpose-built ones. Private suites aren’t a niche here — they are the rental supply. Second, the housing stock and the households don’t match: 81% of Cochrane homes have three or more bedrooms, while 58% of households are just one or two people. That gap — big houses, small households — is the plainest structural argument for a suite in the whole region, and it’s reflected in the permits: 2023–2025 were the busiest suite-permit years since 2010.

But every suite is discretionary
Here’s the balancing reality. Under Land Use Bylaw 01/2022, a secondary or backyard suite is a discretionary use in every district that allows it (R-LL, R-LD and R-MX) — and not permitted at all in the medium- and high-density districts. There’s no as-of-right path.
Two limits matter most:
- One accessory suite per lot — you can’t have both a basement suite and a backyard suite.
- The Town can weigh how many suites already exist on the block and refuse one on those grounds. On a street that already has several, that’s a real risk, not a formality — and a reason to check before you design.
A backyard suite can be up to 80 m² at grade (one storey, 4.6 m), with an unusually generous 60% combined lot coverage. Parking is one extra stall for a studio or one-bedroom, two for larger — and no tandem stalls above a garage.
What it costs
Cochrane’s development permit is $500, and the building permit runs $0.50 per square foot (minimum $90), plus $100 each for electrical and plumbing and a 4% Safety Codes levy. (A separate discretionary-use fee may apply on top; because that isn’t settled in the published schedule, we’d price it out for your specific case rather than quote a single total.) There’s no grant — the Town’s own housing consultant states plainly that Cochrane offers no policy-based incentives.
What a Cochrane suite earns
CMHC suppresses Cochrane’s bedroom-level rents because its purpose-built market is too small to report — which is itself the demand story. The Town’s own early-2026 listings scan showed roughly $1,100 for a studio, $1,300 for a one-bedroom and $1,625 for a two-bedroom — useful as a guide, but a listings scan rather than a CMHC survey, so we confirm the real figure for your unit.
What we do — and what we don’t
HouseLyft establishes whether a project stands up before anyone spends money on drawings: whether a discretionary suite is likely to be approved on your block, what a suite costs to build, and what it should earn. Where it works, we hand you to a vetted builder and stay involved. Where it doesn’t, we say so.
We are not a lender and we do not sell mortgages.
One correction worth carrying, because it is still advertised widely: the federal $80,000 Secondary Suite Loan was cancelled in Budget 2025 and never launched. Our financing guide sets out what is actually live.

Common questions about Cochrane suites
No. Every suite in Cochrane is a discretionary use, so meeting the standards doesn’t guarantee approval — and the Town can refuse a suite if the block already has several. It’s worth checking before designing.
No. Cochrane permits one accessory suite per lot, so it’s one or the other.
Up to 80 m² at grade, one storey and 4.6 m, with up to 60% combined lot coverage — more generous coverage than the base district allows.
The demand is strong: private suites make up the vast majority of Cochrane’s rental supply, and most homes are large while most households are small. We’d still confirm the current rent for your unit.
No. The Town offers no housing incentives, and the cancelled federal $80,000 loan never launched.
