ADU – Accessory Dwelling Unit


The Los Angeles Department of Building and Safety (LADBS) implemented the Standard Plan Program to provide LADBS customers with a simplified permitting process for the design and construction of ADUs that are built repeatedly. The use of standard plans reduces the time required for plan checks resulting in faster permit issuance.

Under the Standard Plan Program, plans are designed by private licensed architects, and engineers to accommodate various site conditions. Plans are then reviewed and pre-approved by LADBS for compliance with the Building, Residential, and Green Codes. When the applicant selects an approved Standard Plan, LADBS staff will review site-specific factors for your property, including compliance with the Zoning Code and foundation requirements.
