How this works & a note on accuracy. Each state links to the official, free full text — we link the source, we don't reproduce copyrighted code text. Editions are current as of October 31, 2026 and shown at the code-family level; local jurisdictions amend and can be ahead of or behind the state. Anything marked "confirm", "varies", or shown in amber must be verified with the Authority Having Jurisdiction (AHJ). General information, not legal or code advice.
