Calgary Secondary Suite Incentive Program

Calgary's housing demand has been climbing steadily, and homeowners are increasingly looking for ways to benefit financially while contributing to the solution. The Calgary Secondary Suite Incentive Program, launched by the City of Calgary, gives qualifying homeowners up to $10,000 to build and register a legal basement suite Calgary homeowners can qualify for within their home.

It is a real opportunity to generate rental income, increase your property value, and help ease the city's housing pressure at the same time. This page covers who qualifies, how much funding is available, what the process looks like, and how to avoid common mistakes, including important note considerations.

What Is the Calgary Secondary Suite Incentive Program?

The Calgary Secondary Suite Incentive Program is a City of Calgary initiative designed to increase the supply of safe, affordable rental housing by encouraging homeowners to build and register legal secondary suites through the Calgary Secondary Suite Grant. The program was launched in 2023 to help homeowners build a safe secondary suite, and is funded through both the municipal budget and the federal Housing Accelerator Fund through Canada Mortgage and Housing Corporation (CMHC).

A secondary suite is a self-contained living space within a home, such as a basement suite or a main-floor suite. Detached backyard suites remain outside this program's scope, including those under the backyard suite incentive program, as does any detached structure in the rear yard. The program covers suites built within the main dwelling only.

Participating in the suite incentive program also contributes to positive urban transformation by expanding housing options and improving affordability across the city.

Who Qualifies for the Incentive?

Before applying, homeowners need to confirm they meet the eligibility criteria. Here is what you need in place:

• Your property must be within Calgary city limits and zoned to allow secondary suites.
• You must be the registered owner and retain ownership throughout the entire process.
• You must have an active building permit number before applying to the program.
• The suite must be located within the main dwelling, not a detached structure.
• Any work completed before your application date will not qualify for funding.
• The incentive is limited to one application per homeowner.
• You must complete a mandatory online eLearning course covering safety elements and regulations before applying.
• The suite must meet all current building codes and safety standards under the Alberta Building Code.

Applications are submitted through apply.calgary.ca, and application review is conducted on a first-come, first-served basis. Funding is limited, so applying early matters.

How Much Funding Can Homeowners Receive?

The maximum grant for building a legal secondary suite within the main dwelling is $10,000. The program reimburses specific required safety elements that are absent from the space at the time of application, not general construction costs.

Here is what the secondary suite funding Calgary program covers:

• Egress windows: Up to $1,500 for bedroom windows large enough to serve as an emergency escape route.
• Smoke and carbon monoxide alarms: Up to $1,000 for interconnected smoke and carbon monoxide alarms throughout the suite.
• Smoke-tight barriers: Up to $4,000 for barriers separating the suite from the main dwelling.
• Energy efficiency bonus: Up to $1,250 for ENERGY STAR certified egress windows and split heating or air conditioning units.
• Accessibility improvements: Up to $5,000 in additional funding for suites designed to meet common mobility challenges, including accessible entrances, units designed for accessibility, and a minimum turning diameter within the living area.

The rebate is issued after all required permits pass city inspections, the suite is registered, and the homeowner submits paid receipts and documentation, including offsite connections where applicable. There is no upfront payment. The Housing Accelerator Fund backing the program closes September 1, 2026, and since applications are processed in order of receipt, acting sooner puts you in a stronger position.

Why This Program Is a Major Opportunity for Homeowners

Generate Rental Income

Renting out a secondary suite can provide homeowners with a steady stream of income to help offset mortgage costs or contribute to savings through available basement suite incentives in Alberta programs. Calgary's rental market remains active, and a registered, legal basement suite gives tenants confidence that the unit is safe and compliant and gives homeowners added protection against liability. Homeowners who receive funding must agree not to license the suite as a short-term rental for at least two years, making this a long-term income strategy.

Increase Property Value

Developing a secondary suite can increase the value of a home by 2% to 5% or more, making it an attractive feature for potential buyers. A legal suite with registered status and documented rental income potential is a tangible selling point in Calgary's competitive housing market.

Multi-Generational Living

Not every homeowner builds a suite for a tenant, and housing needs vary from one family to the next. A separate living space within the same property works well for aging parents or adult children who need independence without being far from family. Secondary suites offer flexibility, whether the space is used for rental income, family members, or a home office, depending on what life calls for.

Steps to Build a Legal Secondary Suite in Calgary

Here is how to build a legal basement suite Calgary homeowners can complete from start to finish:

1. Check zoning: Confirm your property is in a zone that permits secondary suites through the City of Calgary's planning tools.
2. Secure your building permit: You must have a building permit number before applying for the incentive. Depending on your project scope, a development permit may also be required. Both are submitted through apply.calgary.ca.
3. Complete the eLearning course: This mandatory step covers safety requirements and suite regulations. It must be done before submitting your application.
4. Apply to the program: Submit your application with your building permit number. Only work completed after this date qualifies for funding.
5. Design and construction: Once you receive approval from the city, proceed with construction, ensuring all safety requirements are met.
6. Pass all inspections: The suite must pass building, mechanical, and electrical permit inspections with no outstanding deficiencies, then be registered with the city.
7. Claim your rebate: Submit paid receipts and required documentation after successful completion and photo verification.

Common Mistakes to Avoid When Applying

Starting work before approval: Any work completed before your application date is not eligible for reimbursement. This is the most common and costly mistake homeowners make.

Not meeting Calgary basement suite requirements: Your suite must meet current building codes in full. A failed inspection means delays, added costs, and a potential loss of funding.

Underestimating costs: The program covers specific safety elements, not total construction, including underground infrastructure costs. Total costs vary depending on the size, layout, and condition of your space, and will typically exceed the $10,000 grant significantly, so budget accordingly before you begin.

Missing documentation: All eligible work requires paid receipts and photo verification. Poor recordkeeping will hold up or invalidate your rebate claim.

Skipping the eLearning course: This is a required step. Not completing it before applying will block your application from moving forward.

Why Working With a Professional Matters

The application process for Calgary's secondary suite incentive program involves permits, inspections, code compliance, and strict sequencing. Getting any step out of order can cost you your eligibility or result in legal complications later.

A professional contractor ensures your suite is designed to meet all safety requirements from the start, including egress windows, interconnected smoke and carbon monoxide alarms, and smoke-tight barriers. They also help you sequence the work correctly so that eligible safety elements are not completed before your application is submitted, which would disqualify them from funding.

When funding is limited, and applications are reviewed in order of receipt, working with an experienced team means faster, more accurate permit submissions and fewer delays. The difference between a smooth approval and a costly setback often comes down to who is managing your project, for example, experienced contractors who can provide full support.

Is the Calgary Secondary Suite Incentive Program Worth It?

The Calgary Secondary Suite Incentive Program is a real financial opportunity for Calgary homeowners. With up to $10,000 in secondary suite funding Calgary homeowners can access, long-term rental income potential and the ability to increase their property's value, the case for building a legal suite is strong. Since funding is limited and tied to a federal program closing in September 2026, the time to act is now.

The rules are clear but firm: do not start any construction before you apply, keep all documentation, and make sure every safety element is completed in the right order. The fastest path to a smooth, compliant build is working with a team that already knows this process inside and out.
