Data worth citing.
Sources worth checking.

For Canadian journalists, trade associations, researchers and local publishers who need to compare permit guidance without presenting an unverified rule as fact.

Editorial resources, not a badge exchange.

Use the facts you can verify. Cite the relevant page when it helps readers follow the evidence. No reciprocal link, directory account or payment is required.

What the data can prove.

BuildRules summarizes publicly available guidance. Its comparisons are not a municipal portal, legal opinion, professional certification or project approval.

Trace the answer. Each citable row or guide should be checked against its linked municipal authority and last published source review.

Quote its limits. A shed rule from one municipality does not establish what is permitted at a specific address, or in another city.

Link to the exact source. A contextual editorial link helps readers inspect the latest evidence. A badge installation is never required to access or cite the research.
