If you’re thinking about adding a legal secondary suite in Calgary, the City offers financial support to help offset upgrade costs. The Calgary Secondary Suite Incentive Program was created to encourage safe, code-compliant basement suites and increase affordable rental housing across the city.
Here’s what Calgary homeowners need to know before applying.
How Much Funding Can You Get?
Eligible homeowners can receive up to $10,000 to help cover the cost of required safety upgrades when developing or legalizing a secondary suite.
The funding is designed to support:
Fire safety improvements
Egress (escape) windows
Smoke and carbon monoxide alarms
Proper fire separation
Code-compliant exits
Ventilation and heating upgrades (if required)
In some cases, additional support may apply for energy-efficiency or accessibility upgrades.
Important: This incentive helps offset costs — it does not fully pay for building the suite.
Who Qualifies for the Calgary Secondary Suite Grant?
To be eligible:
You must own and live in the home (owner-occupied).
The suite must be located within the main house (typically a basement suite).
You must have an approved building permit before applying.
Work completed before application is generally not eligible.
Detached backyard suites are not included in this program.
Only one application per homeowner is typically allowed.
What the Incentive Actually Covers
The program focuses on making suites legal and safe under Calgary building code requirements.
Common upgrades that qualify include:
Enlarging basement windows for emergency exit
Installing interconnected smoke alarms
Improving fire-rated drywall or ceilings
Adding protected exit pathways
Upgrading mechanical systems if required by inspection
Funding is based on missing safety items identified during the review process.
⚠ Important Conditions to Consider
Before moving forward, homeowners should know:
You must apply before construction begins.
The suite must meet City of Calgary regulations.
There may be restrictions related to short-term rental licensing.
Funding is limited and subject to program availability.
