Building an ADU requires thoroughly understanding the La Jolla permit process and the regulations involved. ADUs can provide a great source of extra income, offer flexible living arrangements, and add value to your property. So the effort won’t be in vain.

La Jolla ADU Permit Regulations

Before you start building your ADU, it’s important to understand the zoning requirements and restrictions in La Jolla. Different ADUs are allowed in La Jolla, including attached ADUs, detached ADUs, and garage conversions.

Each type has different zoning requirements and restrictions, so choosing the right type of ADU for your property is important.

  • Applying for a La Jolla ADU Permit

To apply for a La Jolla ADU permit, you must submit a set of plans showing the design and construction of your ADU. A licensed architect or engineer must prepare these plans. You will also need to pay the permit fee, which varies depending on the size and complexity of your ADU.

After you have submitted your permit application, the city of La Jolla will review your plans and determine if they comply with the local building codes and regulations. This review process can take several weeks to several months, depending on the complexity of your project.

  • Construction and Inspection

During the construction process, several inspections will need to be carried out to ensure that your ADU is built to code and is safe for occupancy.

The first inspection is the foundation inspection, carried out after the foundation has been installed. There will also be plumbing, electrical, and mechanical systems inspections.

City officials will conduct the occupancy inspection after the construction of your ADU is complete. Once you pass this inspection, you will receive a Certificate of Occupancy, allowing you to rent out your ADU.
