How We Collect This Data

Every permit fee in this database is individually researched from the city's published fee schedule. No estimates, no third-party aggregation. We read the actual ordinance, fee table, or rate schedule, then compute the fee using the city's own formula.

When we publish an average: a figure like "the average bathroom remodel permit fee" is the plain mean of the verified fees for that one project scope across every city we track, with the median alongside it on the data pages. We never blend project types into one blanket number, and there is no one-figure national average permit cost here. Fees are set city by city. The honest answer is the per-city table behind each average.

Update Schedule

We re-verify cities on a rolling schedule. If a fee schedule changes between passes, the number may be temporarily out of date. The source URL always points to the current fee schedule so you can verify.
