What is in this library?
The library combines collected code text, selected statutory provisions, regulations, official guidance and procedure documents. A topic is a route through these sources, not a complete statement of the law for a property.
- Check what the document covers
- Some sources are full codebooks; others are selected sections or snapshots. Topic pages identify collected groups and subjects without a dedicated listing.
- Read the edition and official source
- Open the document to check its source and edition. Regulations, agency guidance and dated notices are identified separately.
- Connect state, federal and local sources
- Related federal material appears on topic pages. City and county codes have their own location directory, including local amendments.
GoCodebook provides public access, search, citation, multilingual explanation, and practical interpretation of legally adopted building regulations. It is not a substitute for the official ICC or California code publications.
