No More Owner-Occupancy Requirements.

This bill would delete the provision authorizing the imposition of standards on lot coverage and would prohibit an ordinance from imposing requirements on minimum lot size. The bill would revise the requirements for an accessory dwelling unit by providing that the accessory dwelling unit may be attached to, or located within, an attached garage, storage area, or an accessory structure, as defined.

(3) Existing law prohibits a local agency from requiring a setback for an existing garage that is converted to an accessory dwelling unit or to a portion of an accessory dwelling unit. Existing law requires that an accessory dwelling unit that is constructed above a garage have a setback of no more than 5 feet.

This bill would instead prohibit a setback requirement for an existing living area or accessory structure or a structure constructed in the same location and to the same dimensions as an existing structure that is converted to an accessory dwelling unit or to a portion of an accessory dwelling unit. The bill would also instead require a setback of no more than 4 feet for an accessory dwelling unit that is not converted from an existing structure or a new structure constructed in the same location and to the same dimensions as an existing structure.

(4) Existing law provides that replacement offstreet parking spaces, required by a local agency when a garage, carport, or covered parking structure is demolished in conjunction with the construction of an accessory dwelling unit or converted to an accessory dwelling unit, may be located in any configuration on the same lot as the accessory dwelling unit, except as provided.

This bill would instead prohibit a local agency from requiring the replacement of offstreet parking spaces when a garage, carport, or covered parking structure is demolished or converted, as described above.

(5) Existing law requires a local agency to ministerially approve or deny a permit application for the creation of an accessory dwelling unit or a junior accessory dwelling unit within 120 days of receiving the application.

This bill would instead require a local agency to ministerially approve or deny a permit application for the creation of an accessory dwelling unit or junior accessory dwelling unit within 60 days from the date the local agency receives a completed application if there is an existing single-family or multifamily dwelling on the lot. The bill would authorize the permitting agency to delay acting on the permit application if the permit application is submitted with a permit application to create a new single-family or multifamily dwelling on the lot, as specified.

(6) Existing law prohibits a local agency from utilizing standards to evaluate a proposed accessory dwelling unit on a lot that is zoned for residential use that includes a proposed or existing single-family dwelling other than the criteria described above, except, among one other exception, a local agency may require an applicant for a permit to be an owner-occupant of either the primary or accessory dwelling unit as a condition of issuing a permit.

This bill, until January 1, 2025, would prohibit a local agency from imposing an owner-occupant requirement, as described above.

(7) Existing law authorizes a local agency to establish minimum and maximum unit size limitations on accessory dwelling units, provided that the ordinance permits an efficiency unit to be constructed in compliance with local development standards.

This bill would prohibit a local agency from establishing a minimum square footage requirement for either an attached or detached accessory dwelling unit that prohibits an efficiency unit, as defined. The bill would also prohibit a local agency from establishing a maximum square footage requirement for either an attached or detached accessory dwelling unit that is less than 850 square feet, and 1,000 square feet if the accessory dwelling unit contains more than one bedroom. The bill would also instead prohibit a local agency from establishing any other minimum or maximum size for an accessory dwelling unit, size based upon a percentage of the proposed or existing primary dwelling, or limits on lot coverage, floor area ratio, open space, and minimum lot size for either attached or detached dwelling units that prohibits at least an 800 square foot accessory dwelling unit that is at least 16 feet in height and with a 4-foot side and rear yard setbacks.

(8) Existing law prohibits a local agency from imposing parking standards for an accessory dwelling unit if, among other conditions, the accessory dwelling unit is located within 1 / 2 mile of public transit.

This bill would make that prohibition applicable if the accessory dwelling unit is located within 1 / 2 mile walking distance of public transit, and would define public transit for those purposes.

(9) Existing law requires a local agency to ministerially approve an application for a building permit to create within a zone for single-family use one accessory dwelling unit per single family lot of the unit that is contained within the existing space of a single-family residence or accessory structure when specified conditions are met, including that the side and rear setbacks are sufficient for fire safety.

This bill would instead require ministerial approval of an application for a building permit within a residential or mixed-use zone to create the following: (1) one accessory dwelling unit and one junior accessory dwelling unit per lot with a proposed or existing single-family dwelling if certain requirements are met; (2) a detached, new construction accessory dwelling unit that meets certain requirements and would authorize a local agency to impose specified conditions relating to floor area and height on that unit; (3) multiple accessory dwelling units within the portions of an existing multifamily dwelling structure provided those units meet certain requirements; or (4) not more than 2 accessory dwelling units that are located on a lot that has an existing multifamily dwelling, but are detached from that multifamily dwelling and are subject to certain height and rear yard and side setback requirements.

(10) Existing law prohibits a local agency, special district, or water corporation from considering an accessory dwelling unit to be a new residential use for purposes of calculating fees or capacity charges.

This bill would establish an exception from the above-described prohibition in the case of an accessory dwelling unit that was constructed with a new single-family home.

(11) Existing law requires a local agency to submit a copy of the adopted ordinance to the Department of Housing and Community Development and authorizes the department to review and comment on the ordinance.

This bill would instead authorize the department to submit written findings to the local agency as to whether the ordinance complies with the statute authorizing the creation of an accessory dwelling unit, and, if the department finds that the local agency’s ordinance does not comply with those provisions, would require the department to notify the local agency within a reasonable time. The bill would require the local agency to consider the department’s findings and either amend its ordinance to comply with those provisions or adopt it without changes and include specified findings. If the local agency does not amend it ordinance or does not adopt those findings, the bill would require the department to notify the local agency and authorize it to notify the Attorney General that the local agency is in violation of state law, as provided. The bill would authorize the department to adopt guidelines to implement uniform standards or criteria to supplement or clarify the provisions authorizing accessory dwelling units.

(12) Existing law defines the term “accessory dwelling unit” for these purposes to mean an attached or a detached residential dwelling unit which provides complete independent living facilities for one or more persons.

This bill would revise the definition to additionally require an accessory dwelling unit be located on a lot with a proposed or existing primary residence in order for the provisions described above to apply.

(13) This bill would incorporate additional changes to Section 65852.2 of the Government Code proposed by SB 13 to be operative only if this bill and SB 13 are enacted and this bill is enacted last.

(14) By increasing the duties of local agencies with respect to land use regulations, this bill would impose a state-mandated local program.

(15) 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.

(16) This bill would include findings that the changes proposed by this bill address a matter of statewide concern rather than a municipal affair and, therefore, apply to all cities, including charter cities.
