Townline

Permit and license data, by industry

Building permits, home projects and new restaurants across New York, New Jersey, Connecticut and Philadelphia, delivered by API: 1,036,840 permits on file, updated every day. Each page below shows what one kind of team gets: the records and fields it uses, examples, and what teams like it do with them.

The datasets

Three datasets, one API.

Every page above draws on the same API. Building permits and home projects come in the permit feed, new restaurants in a feed of their own; one key can carry both, limited to the counties you work in.

Building permits

New buildings, renovations, changes of use and demolitions on every kind of property, tagged by trade, with the job value and contractor when the town records them.
