What is CA SB 1090 about?
Under the Planning and Zoning Law, the legislative body of a county or city may adopt ordinances that, among other things, regulate the use of buildings, structures, and land, as provided. The Subdivision Map Act vests the authority to regulate and control the design and improvement of subdivisions in the legislative body of a local agency and sets forth procedures governing the local agency's processing, approval, conditional approval or disapproval, and filing of tentative, final, and parcel maps. Existing law authorizes a development proponent to submit an application for a housing development project on a subdivided lot, as specified, that meets specified requirements, and requires a local agency to ministerially consider that application, as specified. Existing law requires a local agency to ministerially consider, without discretionary review or a hearing, a parcel map or a tentative and final map for a housing development project that meets specified requirements. This bill would, until January 1, 2030, provide that the above-described ministerial approval requirements do not apply to an application for a proposed housing development or map located in ZIP Code 91001 or 91003 and submitted on or after October 1, 2026, except as specified. This bill would make legislative findings and declarations as to the necessity of a special statute for the unincorporated area known as Altadena in the County of Los Angeles. This bill would incorporate additional changes to Section 65852.28 of the Government Code proposed by AB 2601 and SB 1116 to be operative only if this bill and either or both AB 2601 and SB 1116 are enacted and this bill is enacted last. This bill would incorporate additional changes to Section 66499.41 of the Government Code proposed by AB 2601 and SB 1116 to be operative only if this bill and either or both AB 2601 and SB 1116 are enacted and this bill is enacted last. This bill would declare that it is to take effect immediately as an urgency statute.
