Home Additions in Calgary
When the house is right but the space isn't, an addition gives you room without the cost and upheaval of moving.
What home additions involves
A home addition extends your house outward or upward: a rear extension, a second storey, a sunroom or a garage. It ties new foundations, framing and roofing into the existing structure, so it needs a building permit, and sometimes a development permit, from the City of Calgary.
Who it’s for
- Growing families who need more bedrooms or living space
- Owners who like their neighbourhood and want to stay
- Homes that need a garage, mudroom or main-floor suite
What the work usually includes
- Measurements, planning and drawings coordination
- Foundations and framing tied into the existing house
- Roofing, windows and exterior finishes
- Insulation, drywall and interior finishing
- Permits, inspections and licensed trades where required
Permits for additions

Addition questions
Does a home addition need a permit in Calgary?
Yes. An addition changes the structure and footprint of your home, so it needs a building permit from the City of Calgary, and depending on its size and position it may also need a development permit. Your written contract should say who applies for permits and books inspections.

Is it safe to pay a contractor a deposit in Alberta?
Only pay a deposit to a contractor licensed by Service Alberta as a prepaid contractor. Alberta requires that licence before a contractor can take money before the work is finished, and licensed contractors post security with the province. Bedrock Contracting holds a prepaid contractor licence, and you can check it on Service Alberta's licensed business search.
