State building codes

Each tile shows the code editions that state has adopted and the date BuildSpec last checked that adoption record against its published source. Where no verified record exists we say so rather than showing a date. How this is checked.

These are the state’s adopted editions, not the edition BuildSpec serves.The code text in the viewer is 2021 model text and carries no jurisdiction-adoption record — where the two differ, and where your jurisdiction has published amendments, the jurisdiction’s own adopted text governs.
