Common questions

Can I look up one address?

Files are sold by county or state. Every row carries the site address, so any address in the county is one filter away.

How recent are the permits?

A monthly subscription delivers a fresh file of the trailing 12 months every month; a full-history file is cut from the latest snapshot.

What formats do files come in?

CSV, Excel or Parquet, chosen per order.

How is it priced?

Counties are $250–$500 for the full history or $45–$75/mo for monthly updates, by county size. Statewide files are priced on permit count and never cost more than their counties combined. Every county and state page shows its exact price.
