Pre-Approved ADU Plans Program

The ADU Standard Plan Program offers pre-approved architectural and structural plans designed by licensed professionals. These plans are reviewed and approved by the City of Irvine to ensure compliance with building codes. 

Key Features of the Standard Plan Program:

  • Variety of Plans: The program offers a range of pre-approved plans to accommodate different site conditions.
  • Pre-Approved: Plans have already been reviewed and approved by the City, streamlining the approval process.
  • Site-Specific Review: The pre-approved standard plan must be submitted along with a building permit application to the City of Irvine. The City will then conduct a thorough review of the site-specific factors to ensure compliance with zoning codes and foundation requirements.

Benefits of Using Standard Plans:

  • Faster Approval: Pre-approved plans can expedite the approval process.
  • Cost-Effective: Reduces permit application costs.
  • Quality Assurance: Plans are designed and reviewed by professionals, ensuring quality and compliance.

Process for Using Standard Plans:

  1. Select a Plan: Choose a pre-approved plan that meets your needs and site conditions.
  2. Submit Application: Submit the necessary permit application and construction documentation to the City, as outlined on the Accessory Dwelling Unit information page.
  3. Site-Specific Review: The City will review your documentation to ensure compliance with applicable site-specific zoning and building code requirements.
  4. Approval: If everything is in order, the City will approve your plans and issue a building permit.

Additional Considerations:

  • Customization: While standard plans are pre-approved, you may still need to make minor modifications to accommodate your specific site or preferences.
  • Local Regulations: Always consult with the City of Irvine to ensure compliance with all local regulations and zoning requirements.

Overall, the Standard Plan Program offers a convenient and efficient way to obtain building permits for residential projects in Irvine. By using pre-approved plans, you can potentially save time and money while ensuring compliance with building codes.
