Real municipal rules. Plain-language decisions.

Can I build this?

A quick, source-linked starting point for deck and shed projects. Pick the municipality and the work; answer the actual questions that can change a building-permit requirement.

A general permit exemption does not approve the project's location, setbacks, zoning or final design. The municipality decides the actual application.

01 / Choose your pre-check

Start with the project, then the city.

Only combinations with an existing, reviewed decision model are interactive. Other project types are linked to their detailed city guides instead.

Secondary suites / A different kind of decision

Thinking about a basement apartment or second unit?

Secondary-suite requirements involve zoning, exits, fire and construction conditions, and sometimes other reviews. BuildRules does not currently offer a reliable yes/no interactive pre-check for these projects. Start with the municipality's sourced guide, then verify the address and proposed work.
