The parking requirements for ADU
What is the parking requirement for an ADU in Manhattan Beach?
In Manhattan Beach, each ADU should have one off-street parking space, except under certain circumstances: if it's within half a mile of public transit, located in a historically significant district, part of the primary dwelling or an existing accessory structure, in an area without on-street parking permits for ADU occupants, or within one block of a city-approved parking space for a car-share vehicle.
Where can I have a parking space on my property?

If an ADU is created by converting or removing a garage or carport, there's no requirement to replace those parking spaces, as long as the ADU complies with regulations. Driveways that served parking spaces converted to ADUs can still be used for parking.
How to get permits for your ADU
How long does it take to get an ADU permit in Manhattan Beach?
In Manhattan Beach, obtaining an ADU permit usually takes 3.5 to 4 months. After finalizing the permit plans, submit them for a Plan Check. It's recommended to schedule a pre-plan check meeting with a planner to ensure everything is accurate before submitting.
Once the application is submitted and fees are paid, the city has 60 days to determine if it's complete. If there's no response during this period, the permit is automatically approved. If revisions are required, your designer will need to update and resubmit the plans. The application should meet all ADU requirements, and missing details won't result in a denial. The Plan Check fee is about $4,283.

Are ADUs rent-controlled in Manhattan Beach?
In Manhattan Beach, ADUs are not subject to rent control laws. This exemption is due to their classification as new constructions, which exempts them from regulations like AB 1482, allowing landlords to annually increase rents. However, this exemption only applies to structures that are at least 15 years old.
How do I get money to build an ADU in Manhattan Beach?
To secure funding for constructing an ADU in Manhattan Beach, homeowners can consider applying for the CalHFA's ADU grant program, administered by the California Community Economic Development Association (CCEDA).
