Accessory Dwelling Unit (ADU)
The ADU Ordinance
On December 11, 2019, the City of Los Angeles adopted the Accessory Dwelling Unit Ordinance (Ordinance 186,481) which went into effect on December 19, 2019. This ordinance added a new section, Los Angeles Municipal Code (LAMC) Section 12.22A.33, which includes local development standards and requirements for Accessory Dwelling Units (ADUs), Junior Accessory Dwelling Units (JADUs), and Movable Tiny Houses (MTHs).

Standard Plans
Program
The Standard Plan Program makes it easier for LADBS customers to get permits for building Accessory Dwelling Units (ADUs) built repeatedly. Using standard plans shortens the time needed to review the plans through plan check, and corresponding permits are issued more quickly.
Under The Standard Plan Program private licensed architects and engineers create plans suitable for different types of sites. LADBS pre-approves these plans to make sure they meet building, residential, and green codes. If you choose an approved plan, LADBS will review it to make sure it fits your property, following zoning codes and foundation needs.

While the Pre-Approved Standard Plan Program streamlines the building and safety review process, other agency/departmental reviews and clearances may still be required depending on your specific site conditions and type of rebuild. Homeowners should be prepared to obtain additional approvals as part of the permitting process.
