Townline

Solar permit data for New York, New Jersey and Connecticut

Every solar permit we collect, with the address, town and date, the installer when the permit names one, the system size when it gives one, and the job value when the town records it. Plus roofing and electrical permits on single-family homes, which show the homes that just put on a new roof or upgraded their electrical service.

Delivery

Pull what changed, not the whole file.

Every dataset is a feed with a cursor, delivered by API. Run it hourly, daily or weekly, and never re-download yesterday’s records.

01
Changes, not dumps — Your first pull returns the backlog. After that, each pull returns only what's new or changed since the last one: new records, status changes, and new filings on a place you already have.
02
Search when you need it — Look up permits by county, town, trade, property type, status, date or keyword, sorted by date or valuation.
03
One key for your team — JSON over HTTPS, up to 1,000 records a call, limited to the areas you license.
