When is the Calgary secondary suite amnesty deadline?

Quick Answer

December 31, 2026. The City of Calgary's Secondary Suites Amnesty Program waives development permit and registration fees for existing unpermitted or non-conforming secondary suites (built before March 12, 2018) until midnight December 31, 2026. The complementary $10,000 Secondary Suite Incentive Program (SSIP) is funded through the federal Housing Accelerator Fund and may exhaust before December 31, so apply early to secure both the fee waiver and the grant.

Legalising an existing basement suite in Calgary in 2026 is meaningfully cheaper than at almost any point before, thanks to two overlapping City of Calgary programs. The amnesty waives permit and registration fees. The incentive grants up to $10,000 toward the safety work required to legalise the suite. Both are time-limited.

Key Facts

  • Amnesty deadline: December 31, 2026 (hard cutoff).
  • Suite must have been built before March 12, 2018 to qualify.
  • Incentive grant amount: up to $10,000 per qualifying homeowner (SSIP).
  • SSIP funding source: federal Housing Accelerator Fund (may reach capacity before December 31, 2026).
  • Typical rent uplift from legalising a Calgary basement suite: $900 to $1,400 per month.

What the amnesty program actually covers

The amnesty waives development permit fees and registration fees that would normally apply when bringing an existing unpermitted suite into compliance. The homeowner is still responsible for any required safety upgrade work (typically $5,000 to $25,000 depending on the suite's starting condition). The SSIP grant covers up to $10,000 of that safety work.

What safety upgrades are typically required?

  • Drywall barriers in furnace and mechanical rooms.
  • Smoke-tight barriers in shared stairways.
  • Egress windows in basement bedrooms.
  • Hardwired, interconnected smoke and carbon monoxide detectors.
  • Fire-rated doors between the suite and shared spaces.
  • Updated electrical panel capacity where required.

What happens if I miss the December 31, 2026 deadline?

The fee waivers expire. Future legalisation is still possible but subject to full development permit fees, registration fees, and any applicable retroactive enforcement costs. The SSIP grant is separately tied to federal HAF funding availability and may not be available at all after the program funding is exhausted.

Is the ROI worth the safety work?

For most Calgary detached homes with an existing basement suite, yes. A legal suite typically adds $900 to $1,400 per month of rental income, produces a 5 to 10 percent property value uplift, and protects the owner from insurance-void risk that comes with an unpermitted suite. Payback is typically 1 to 5 years depending on the specific math.
