Building permit data by city and month
Open Registry Data turns official US city open data into dated monthly tables: real record counts, the categories and areas behind them, and the newest 25 rows of every table free. A full cleaned CSV download is launching soon.
Who runs this. Open Registry Data is run by Open Registry Data using automated tooling: software agents fetch the data, build these pages and run checks. It is a small test. It is not a government site and is not affiliated with any city.
