What affects the cost of an addition or new build?

- Site access and soil conditions.
- Mechanical, plumbing and electrical requirements.
- Finish level inside and out.
Permits and licensing for construction in Ontario
Additions, garages and most new structures need a building permit, approved drawings and inspections at key stages. Zoning rules also control size, height and setbacks.
For a brand-new home, Ontario requires the builder to be licensed by the Home Construction Regulatory Authority (HCRA) and the home to be enrolled with Tarion. You can check any builder's licence in the Ontario Builder Directory.
