Code library
Which building code applies where.
The adopted code edition for every U.S. state and territory, broken out by discipline (building, residential, fire, electrical, plumbing, mechanical, energy, and accessibility), plus the local amendments for 78 cities and counties. This is the same adoption map Architechtura's plan review resolves against, so what you read here is what a review would actually apply.

Check a plan set against your jurisdiction’s code
Knowing the adopted edition is the easy half. Architechtura reads your drawings, resolves which of these provisions actually apply to the project, and returns the corrections a plan checker would write up, each one cited to the section it came from.
Your first check is free, no card required.
Compiled from published state and municipal adoption ordinances. Local governments amend their codes on their own schedule, and a pending ordinance can change what applies to your permit. Confirm the governing edition with the building department before you submit. This page is reference information, not a code determination.
