A city or county may require that the seller provide specific information about the neighborhood or community: The Civil Code requires that such local disclosure statements be in the following format:

NOTE: On and after January 1, 2006, should a city or county not adopt a different or additional local disclosure form, then the required "airport influence area," disclosure shall be made consistent with a current airport influence map. If there is not an available current airport influence map, a written disclosure of an airport located within two statute miles of the subject property shall satisfy this disclosure requirement.
When providing the above disclosure, the seller, the seller’s agent(s), or the expert retained for such purpose shall determine whether the property is within the jurisdiction of the San Francisco Bay Conservancy and Development Commission, as defined in Section 66620 of the Government Code. If the property is within the Commission’s jurisdiction, the report shall contain the following notice:
NOTICE OF SAN FRANCISCO BAY CONSERVATION
AND DEVELOPMENT COMMISSION JURISDICTION
This property is located within the jurisdiction of the San Francisco Bay Conservation and Development Commission. Use and development of the property within the commission’s jurisdiction may be subject to special regulations, restrictions, and permit requirements. You may wish to investigate and determine whether they are acceptable to you and your intended use of the property before you complete your transaction.
