BUILDING PERMITS A permit is required to construct, enlarge, alter, convert (including change of occupancy, use, or character), repair, move, or demolish a structure. Permits are also required for grading, plumbing, electrical, and mechanical work. Permits must be obtained prior to construction.
The City of San Diego issues Certificates of Occupancy for the following: New non-residential buildings. New multiple dwelling unit buildings. Tenant improvements (TIs) to occupy a shell building or involving a change of occupancy classification.
A Coastal Development Permit (CDP) is required for the creation of all ADUs and JADUs that are not completely contained in the existing primary structure or include increases in habitable area, or include conversion of non-habitable space within the Coastal Overlay Zone.
What are the new ADU regulations in San Diego? The 2025 regulations expand opportunities for ADU development. Multifamily properties can now have up to eight detached ADUs, unpermitted ADUs built before 2020 have a streamlined path to legalization, and coastal properties benefit from faster permitting processes.
Before you can start building your ADU, you will need permission from your local planning department. These permissions are called permits, and their costs vary depending on your location. Building permits range from $2,000 to $10,000, whereas city fees can range from $3,000 to $11,000.
A TCO allows occupancy of a structure prior to final approval by all developmental related Departments. Traditionally, a TCO has been approved for a Tenant/Owner to gain access to a commercial occupancy for stocking of inventory, staff training, installing, and testing of computer systems etc.
A Certificate of occupancy (COO) is necessary for people to occupy the property. without a COO, you ca not legally collect rents as you are renting space that no one should live in. The COO is issued when the building permit is final.
In California, most construction work is required to be performed by a licensed contractor. In certain instances, the owner of the property may secure a permit as an owner-builder, but there are strict limitations on when this may occur.
How do I obtain a Certificate of Occupancy? A completed permit application. Complete construction documents, if applicable. The services of a professional designer may be required to prepare plans for the space. Payment of plan review and permit fees.
Owner-as-Contractor is a type of Owner-Builder where you personally act as your own General Contractor, the permit is taken out in your name and you hire California licensed sub-contractors to perform portions of the construction work.
