Summary
Official abstract published by the California legislature· summary
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 requires a local agency to consider ministerially a specified proposed housing development or to ministerially approve a parcel map for an urban lot split if the development or parcel meets specified requirements, including, that the development or parcel is not located within a historic district or property included on the State Historic Resources Inventory or within a site that is designated or listed as a city or county landmark or historic property or district pursuant to city or county ordinance, as specified. Existing law authorizes a local agency to impose specified objective standards on the development or parcel created by an urban lot split, except as specified.
With respect to ministerial review of a proposed housing development under the above-described provisions, this bill would, if the other specified requirements are met, instead require a local agency to consider ministerially the development that is not located in either a contributing structure within a historic district included on the State Historical Resources Inventory or within a historic property or district pursuant to city or county ordinance or in a parcel individually listed as a historical resource included in the State Historical Resources Inventory or within a property individually designated or listed as a city or county landmark under a city or county ordinance. The bill would also authorize a local agency to adopt objective standards for the purposes of maintaining the historical value of a historic district listed in the California Register of Historical Resources, as specified.
With respect to an urban lot split under the above-described provisions, this bill would, if the other specified requirements are met, instead require a local agency to ministerially approve the urban lot split if the parcel is not located within a historic landmark property included on the State Historical Resources Inventory or within a site that is designated or listed as a city or county landmark pursuant to a city or county ordinance. The bill would additionally require that the proposed urban lot split not require demolition or alteration of specified structures.
By imposing additional duties on local agencies, this bill would impose a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required by this act for a specified reason.
