• 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.
