Building codes by US state — the IBC, IRC and more as adopted into law in each state.

Direct answer and reference scope

US States is presented here as a reference within the the listed code collection collection for Index.Mdx. Building codes by US state — the IBC, IRC and more as adopted into law in each state.

The ICC code library is the model-code publication path. This Harth page is a searchable reference transcription, not an official code publication, legal opinion or confirmation that this edition controls a particular address. Record the project jurisdiction, application date, occupancy, construction type and amendment set before relying on a section. Where this page conflicts with an official publication or the authority having jurisdiction, the official source controls.

It is not legal advice and may not reflect local amendments or the most recently adopted edition. Always verify requirements with the authority having jurisdiction.
