A building permit is a document issued by a municipality authorizing construction, renovation or demolition. Because permits are filed before work begins, they are one of the earliest signals of development activity and neighbourhood change.
Every municipality publishes permits in its own format. Neighbourly normalizes permit data across 20 Canadian cities into a single schema, so renovation history, growth signals and investment patterns can be searched the same way everywhere.
Building Permit is part of the Neighbourly data platform. Explore the API or browse the data layers.
