LEGISLATIVE COUNSEL'S DIGEST
The Planning and Zoning Law also authorizes a local agency, by ordinance or ministerial approval, to provide for the creation of accessory dwelling units in areas zoned for residential use, as specified. Existing law provides that an accessory dwelling unit may either be an attached or detached residential dwelling unit, and prescribes the minimum and maximum unit size requirements and height limitations a local agency may
establish, including a 16-feet height limitation. Existing law provides that a local agency shall ministerially approve an application for a building permit within a residential or mixed-use zone to create 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 a height limitation of 16 feet, among other requirements.
This bill would instead authorize a local agency to establish a height limitation of lower than 18 feet, as specified, for those accessory dwelling units. The bill would create an exception from that limitation to permit a local agency to impose a height limitation of not less than 25 feet if the accessory dwelling unit is within
