A Building Permit legally authorizes you to start construction of a building project in accordance with approved drawings and specifications.
Building Permits are reviewed for compliance with:
- Ontario Building Code
- Hamilton's Zoning By-law
- regulations of the Niagara Escarpment Commission and Conservation Authorities
- other applicable provincial and municipal regulations
The purpose of a Building Permit is to ensure that zoning requirements, fire and structural safety standards and other building standards are met.
When do you need a Building Permit
You need a Building Permit to erect, install, extend, alter or repair a building. If you are demolishing all or part of a building, you will need a Building Permit to Demolish.
