Cal. Gov't Code § 65863.2

(a) A public agency shall not impose or enforce any minimum automobile parking requirement on a residential, commercial, or other development project if the project is located within one-half mile of public transit.
(b) Notwithstanding subdivision (a), a city, county, or city and county may impose or enforce minimum automobile parking requirements on a project that is located within one-half mile of public transit if the public agency makes written findings, within 30 days of the receipt of a completed application, that not imposing or enforcing minimum automobile parking requirements on the development would have a substantially negative impact, supported by a preponderance of the evidence in the record, on any of the following:
1. (1) The city’s, county’s, or city and county’s ability to meet its share of the regional housing need in accordance with Section 65584 for low- and very low income households.
2. (2) The city’s, county’s, or city and county’s ability to meet any special housing needs for the elderly or persons with disabilities identified in the analysis required pursuant to paragraph (7) of subdivision (a) of Section 65583.
3. (3) Existing residential or commercial parking within one-half mile of the housing development project.
(c) For a housing development project, subdivision (b) shall not apply if the housing development project satisfies any of the following:
1. (1) The development dedicates a minimum of 20 percent of the total number of housing units to very low, low-, or moderate-income households, students, the elderly, or persons with disabilities.
2. (2) The development contains fewer than 20 housing units.
3. (3) The development is subject to parking reductions based on the provisions of any other applicable law.
(d) Notwithstanding subdivision (a), an event center shall provide parking, as required by local ordinance, for employees and other workers.
(e) For purposes of this section:
1. (1) “Housing development project” means a housing development project as defined in paragraph (2) of subdivision (h) of Section 65589.5.
2. (2) “Low- and very low income households” means the same as “lower income households” as defined in Section 50079.5 of the Health and Safety Code.
3. (3) “Moderate-income households” means the same as “persons and families of moderate income,” as defined in Section 50093 of the Health and Safety Code.
4. (4) “Public agency” means the state or any state agency, board, or commission, any city, county, city and county, including charter cities, or special district, or any agency, board, or commission of the city, county, city and county, special district, joint powers authority, or other political subdivision.
5. (5) “Public transit” means a major transit stop as defined in Section 21155 of the Public Resources Code.
6. (6) “Project” does not include a project where any portion is designated for use as a hotel, motel, bed and breakfast inn, or other transient lodging, except where a portion of a housing development project is designated for use as a residential hotel, as defined in Section 50519 of the Health and Safety Code.
(f) This section shall not reduce, eliminate, or preclude the enforcement of any requirement imposed on a new multifamily residential or nonresidential development that is located within one-half mile of public transit to provide electric vehicle supply equipment installed parking spaces or parking spaces that are accessible to persons with disabilities that would have otherwise applied to the development if this section did not apply.
(g) When a project provides parking voluntarily, a public agency may impose requirements on that voluntary parking to require spaces for car share vehicles, require spaces to be shared with the public, or require parking owners to charge for parking. A public agency may not require that voluntarily provided parking is provided to residents free of charge.
(h)
1. (1) Subdivision (a) shall not apply to commercial parking requirements if it conflicts with an existing contractual agreement of the public agency that was executed before January 1, 2023, provided that all of the required commercial parking is shared with the public. This subdivision shall apply to an existing contractual agreement that is amended after January 1, 2023, provided that the amendments do not increase commercial parking requirements.
2. (2) A project may voluntarily build additional parking that is not shared with the public.
(i) The Legislature finds and declares that the imposition of mandatory parking minimums can increase the cost of housing, limit the number of available units, lead to an oversupply of parking spaces, and increased greenhouse gas emissions. Therefore, this section shall be interpreted in favor of the prohibition of the imposition of mandatory parking minimums as outlined in this section.
