Los Angeles Preapproved ADU Plan

Choosing an Ideal Preapproved ADU Plan

If you are considering a preapproved plan to set out your ADU project, our experts recommend you consider various factors as described below;

Zoning

ADUs are allowed on most residential lots as long as they meet specific zoning requirements, local zoning ordinances may restrict the number of ADUs permitted on a lot, as well as their size and location.

For ADU to be permitted on your property, either junior ADU or detached ADU, it must be zoned for single or multi-family use. In some cases, both detached ADU and junior ADU may be allowed on one lot.

Size and height

ADUs come in various sizes and configurations, from tiny home studios to two-bedroom units; therefore, your ADU’s objective should be considered before making a final decision. For instance;

In Los Angeles, ADUs can be up to 1200 sq. ft. for detached units and up to 50% of the existing living area for attached units.

ADUs within 200 ft. of the highway cannot exceed a height of 18 ft., while 25 ft. is the standard height allowance.

Additional parking

One parking space on site is required for the Los Angeles ADU, unless the ADU is within half a mile of public transportation or if the ADU is part of the primary dwelling.

Your lot size

The size of your property can impact your ability to build an ADU. Local zoning ordinances may restrict the maximum number of units permitted on a lot and their size. For example, some cities within the Bay Area may limit the total square footage of all structures on a lot, impacting your ability to build a detached ADU.

Expense

The ADU preapproved plan is ready for building, lowering the cost of the design process and approval.

Preapproved ADU Plan Set

A preapproved ADU plan set typically includes a comprehensive package of documents and drawings reviewed and approved by the Los Angeles Department of Building and Safety. Some of the elements in a preapproved ADU set plan are:

Site plan

The site plan illustrates the location of the ADU on the property, setbacks, parking area, access points, and any other site-specific details.
