• To obtain a building permit, you will need to provide a completed Building Permit Application, a copy of the LA City approved stamped ADU Standard Plan, and plans indicating how the Standard Plan will be adapted to a specific site. This should include the necessary details indicating how and where the structure will be built in a specific location (i.e. plot plan showing setbacks, etc.).
• All applications and plans must then be submitted at one of our offices or uploaded/submitted via Eplan. No structural calculations are required. The Department will review all of the plans and issue a building permit once it is verified site-specific factors for the property, including compliance with the Zoning Code and foundation requirements.

Most of the ADU Standard Plans have been pre-approved with various options. Some customization is possible, such as changes to window and door types and sizes, colors, etc. Approved standard plan floor plans can also be rotated.

When submitting your Building Permit application, please indicate the ADU Standard Plan number you are using in the work description.
