Tools
| Tool | Description | Behaviour |
|---|---|---|
| list_california_code_documents | List the California codes and local ordinances available for lookup, and what is not covered. Useful before concluding that a code is unavailable, and for finding the exact document or jurisdiction slug that a lookup takes. | Read-only |
| lookup_california_code_section | Look up the VERBATIM text of a California building, residential, fire, plumbing, mechanical, green (CALGreen), energy or existing-building code section, or a section of a California city or county zoning/municipal ordinance, by its section number. Use this whenever the user cites a section number ("CRC R602.10.2.3", "CBC 1004", "§ 17.60.090") or asks what a specific section says. Returns the official text with its citation, edition and a link to the full section. It returns code text only and does not determine whether a specific project complies. | Read-only |
| search_california_codes | Search California building codes (Title 24), state housing law and California city and county zoning/municipal codes by TOPIC, when the user does not already have a section number — e.g. "minimum attic access opening", "ADU setbacks in San Jose". Requires the user's GoCodebook account and uses 1 credit per search (also when nothing is found). If the user already cites a section number, use lookup_california_code_section instead — it is free. Returns ranked excerpts with citations and links. It does NOT decide whether a project complies. | Changes data |
