What is being built, right now.

Building permits are public the moment a city issues them. This reads four official open-data portals live and tells you how many were issued in the last 30 days — by city and by keyword. No login, nothing stored.

Look it up

Queries go from your browser straight to the city portal — we never see them.

When the free count is not enough

This page answers "how much is happening". If you need the records themselves — address, work type, declared cost and the owner and contractor contacts — the same city feeds are available through our pay-per-use tool, filtered and delivered on a schedule.
