Markham building permits: FAQ

How do I search Markham building permits?

Use the search box on this page: type an address, permit number, or contractor and it queries every Markham permit BuildData holds. Records come from Markham's own open data, geocoded and normalized.

How do I check the status of a building permit in Markham?

Search the address above. Each result shows the permit's status, type, issue date, and description as published by Markham. For an application still in progress, the city's own portal remains the authority.

Are Markham building permits public record?

Yes. Markham publishes building permit records as open data, so anyone can look them up. BuildData aggregates, geocodes, and normalizes them so they are searchable in one place instead of one city portal at a time.
