How this data is built

Most "average permit cost" numbers online are guesses, national rules of thumb, or lead-generation filler. These datasets are different. Every figure is the actual permit fee a city charges for a defined project scope, read directly from that jurisdiction's published fee schedule, ordinance, or rate table and computed with the city's own formula. We do not average across cities to invent a single national number and present it as fact. Instead, each project page shows the real fee in every tracked city, then derives the average, median, and range from those verified data points so you can see exactly where the number comes from.

One important distinction: these are government permit fees only, not total project cost. A bathroom remodel permit fee is the amount the building department charges to pull the permit, separate from labor, materials, and contractor markup. Permit fees are set by local government and change periodically, so each dataset is dated and re-verified on a regular cadence. When a city exempts a scope from permitting, we record that as a true zero rather than a missing value.
