Calgary runs two different suite grants, and they are easy to mix up — which leads homeowners to plan around the wrong number. The short answer: a suite inside your home (basement or main floor) may qualify for the $10,000 SSIP; a detached suite in your back yard may qualify for the up to $35,000 Backyard Suite Incentive. A given project qualifies for one program, not both. Here’s how to tell which one is yours.
Airdrie homeowners should read this with one big caution: these are Calgary programs. If the property is in Airdrie, do not build the budget around Calgary SSIP or Calgary’s Backyard Suite Incentive until the local incentive and permit path has been confirmed for that address.
At a glance
| SSIP — Secondary Suite Incentive | Backyard Suite Incentive | |
|---|---|---|
| Covers | A suite within the main dwelling (basement or main-floor secondary suite) | A single, detached backyard suite (laneway home, garden suite, detached garage suite) |
| Maximum | $10,000, plus up to $1,900 energy + $7,500 accessibility | Up to ~$35,000 (see breakdown below) |
| Attached suites? | Yes — that’s the point | Not eligible (attached-to-main excluded) |
| How the amount is set | By which required safety elements are missing at application | By construction + infrastructure + accessibility + no-relaxation components |
| Short-term rental restriction | 2 years | 1 year per $10,000 received (max 3.5 years) |
| Apply before work? | Yes — only work after you apply counts | Yes — seek conditional approval before permits |
| Funding status | Ongoing; funding limited | Launched March 2, 2026; City cautions funds may be gone for applications after April 14, 2026 |
The $10,000 SSIP — for suites inside your home
SSIP supports legal secondary suites built within your main dwelling. The grant is up to $10,000, but the amount isn’t a flat figure — it’s based on which required safety elements are missing when you apply:
| Safety element | Eligible amount |
|---|---|
| Egress window(s) | $1,500 |
| Hardwired, interconnected smoke & CO alarms | $1,000 |
| Protected exiting | $1,000 |
| Smoke-tight barrier | $4,000 |
| Split heat / separate air | $6,000 |
| Maximum | $10,000 |
You can also earn up to $1,900 in energy-efficiency bonuses and up to $7,500 for accessibility features.
Key rules: apply before you do the qualifying safety work (only work dated on/after your application counts); the homeowner applies, not the contractor; a mandatory eLearning course is required; and an incentivized suite can’t be a short-term rental for two years. Importantly, existing and previously unpermitted suites qualify — any homeowner with a secondary-suite building permit is eligible regardless of when it was obtained.

The up-to-$35,000 Backyard Suite Incentive — for detached suites
This newer program (launched March 2, 2026) supports detached suites only. The “$35,000” is a ceiling that combines:
- Up to $15,000 general construction support
- Up to $20,000 infrastructure — 40% of underground infrastructure cost, max $20,000, only when both onsite + offsite servicing are required
- $7,500 accessibility (mobility-supportive design)
- $2,500 for designs needing no Land Use Bylaw relaxations
Because the $20,000 infrastructure piece applies only to projects needing full servicing, most projects qualify for well under $35,000. Eligibility is limited to single, detached suites on privately owned property, one award per applicant/suite.
Funding caution: the program draws on a fixed $10 million federal allocation, and the City has stated funds may not be available for applications received after April 14, 2026. Treat it as possibly fully committed and confirm before relying on it.

Which one is mine? A quick decision guide
- Finishing or legalizing a basement / main-floor suite inside your house? → SSIP ($10,000).
- Building a standalone unit in the back yard (laneway/garden/detached garage suite)? → Backyard Suite Incentive (up to $35,000, if funds remain).
- An above-garage suite attached to your house, or an attached ADU? → Neither program’s grant applies (SSIP is for in-dwelling secondary suites; the Backyard program excludes attached units). You can still build it — just don’t budget a grant.
- Have both a basement and a buildable back yard? Under the 2024 rules some lots could do both; after August 4, 2026 most districts allow one suite or the other. Check your address before planning two units.
Airdrie homeowners: don’t borrow Calgary grant math
The project math can look similar in Airdrie — construction cost, rental income, egress, mechanical, and finish level still drive the decision — but the grant line is not portable. Calgary SSIP is tied to Calgary’s secondary-suite program. Calgary’s Backyard Suite Incentive is also a Calgary program with its own funding limits.
For an Airdrie property, the better sequence is: confirm local permit feasibility, price the basement or renovation scope, then treat any available incentive as upside rather than a guaranteed budget line. If the address is in Airdrie, start with Airdrie basement development or Airdrie basement renovation and keep this article as a Calgary comparison.
A note on timing
All of this intersects with Calgary’s zoning change. Blanket rezoning was repealed effective August 4, 2026, and application cut-offs are already in effect (standalone secondary suites: June 6, 2026). If a suite is in your plans, the grant question and the zoning-deadline question should be answered together. See Calgary’s suite rules change August 4, 2026.
Frequently Asked Questions
Can I get both grants on the same property? Not on the same structure, and a single project qualifies for only one program. If your lot can support both an in-home suite and a detached backyard suite as separate projects, each could be assessed under its own program — but note the post–August 4 “one suite or the other” rule in many districts.
Is the $35,000 guaranteed? No. It’s a maximum combining several components, most projects qualify for less, and program funding is limited and may already be committed.
Does SSIP only cover brand-new suites? No. Existing and previously unpermitted suites with a building permit are eligible; the payout depends on which safety elements are still missing.
Who applies — me or my builder? For SSIP, the homeowner must apply. For both programs, apply before doing the qualifying work. OAF prepares and submits the documentation, but the application is in your name.
