The Pre-Approved ADU Plans Program encourages the construction of new, detached ADUs by offering property owners a selection of Pre-Approved ADU building plans. While some site-specific design work is required, these pre-approved plans aim to help property owners reduce pre-construction costs and improve permit approval efficiency.

Applicants that use a Pre-Approved ADU plan set must submit a complete package through the City's online portal for review and approval. 

A complete package must include: 

• The selected pre-approved ADU plan, with completed title sheet.
• Scaled Site Plan that shows property lines, parcel dimensions, dimensions of your home and all structures on site (e.g., detached garage, storage, pool) and the location of the proposed pre-approved ADU footprint.
• Updated Title 24 energy calculation report with correct name, address, and exact orientation for site specific conditions. Owner may contact the entity who prepared the original report (shown on T24.1) to obtain updates to the report.
• Hold Harmless Agreement
• OCFA Residential Plan Submittal Criteria Form
• City of Laguna Hills ADU Questionnaire
• Soils Report
