Cal. CIV § 1102.6a

(a) On and after July 1, 1990, any city or county may elect to require disclosures on the form set forth in subdivision (b) in addition to those disclosures required by Section 1102.6.

An ordinance like this adopted prior to July 1, 1990, may be amended thereafter to revise the disclosure requirements of the ordinance, in the discretion of the city council or county board of supervisors.

(b) Disclosures required pursuant to this section pertaining to the property proposed to be sold, shall be set forth in, and shall be made on a copy of, the following disclosure form:

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

(c) This section does not preclude the use of addenda to the form specified in subdivision (b) to facilitate the required disclosures. This section does not preclude a city or county from using the disclosure form specified in subdivision (b) for a purpose other than that specified in this section.

(d) (1) On and after January 1, 2005, if a city or county adopts a different or additional disclosure form pursuant to this section regarding the proximity or effects of an airport, the statement in that form shall contain, at a minimum, the information in the statement “Notice of Airport in Vicinity” found in Section 11010 of the Business and Professions Code, or Section 1103.4 or 4255.

(2) On and after January 1, 2006, if a city or county does not adopt a different or additional disclosure form pursuant to this section, then the provision of an “airport influence area” disclosure pursuant to Section 11010 of the Business and Professions Code, or Section 1103.4 or 4255, or if there is not a current airport influence map, a written disclosure of an airport within two statute miles, shall be deemed to satisfy any city or county requirements for the disclosure of airports in connection with sales of real property.
