Permitting guides for every US state
We score every jurisdiction on the factors that drive permit cost and timeline — seismic and coastal zones, wildfire overlays, historic districts and drawing depth. Pick a state to read its full permitting guide, or start an estimate to see your exact address scored.
How the score is built
Each jurisdiction is scored 0–100 by weighting the factors that add permit cost, review time, and drawing scope. Higher score means more complexity — and a higher pricing multiplier applied automatically at estimate time. Open any state guide for the full breakdown, timeline and FAQ.
Ground-motion risk requiring lateral and foundation detailing — highest across the West Coast.
Flood-plain, coastal-construction and drainage rules that add scope and review steps.
Wildland-urban interface ignition-resistant construction requirements.
Landmark and historic-district design review that lengthens approval.
Structural sizing for snow, wind and hurricane loads by climate zone.
How extensive a permit set the jurisdiction requires at submission.
