Pool Permit in San Diego County, California
It depends
Sometimes, depending on the project
Before constructing or installing a residential swimming pool or spa in unincorporated San Diego County, and before modifying an existing one
By Mario Bailey, verified against official sources
Quick answer
San Diego County requires a building permit for a residential swimming pool or spa in every case but one narrow exemption. The adopted ordinance exempts a prefabricated pool accessory to a one- or two-family dwelling only when it is less than 18 inches deep, holds no more than 5,000 gallons, and is installed entirely above ground. Everything else needs a permit, including any in-ground pool, any spa, and any above-ground pool that is 18 inches deep or more or that holds more than 5,000 gallons; failing any one of the three conditions is enough to require the permit. The county has also amended the California Building Code to require four separate drowning-prevention measures on any new or modified pool or spa in the unincorporated area serving a one- or two-family dwelling: an enclosure, at least one safety feature accepted by the County of San Diego, at least one nonredundant safety feature accepted by the State of California, and entrapment avoidance. All four must be installed, inspected and approved before the pool is plastered or filled. This covers unincorporated San Diego County only; the 18 incorporated cities, San Diego, Chula Vista, Oceanside and Escondido among them, run their own building departments.
Typical threshold: The only exempt pool is a prefabricated pool accessory to a one- or two-family dwelling that is less than 18 inches deep, holds no more than 5,000 gallons, and sits entirely above ground; everything else needs a permit.

How to apply in San Diego County
A residential pool permit application covers both construction and safety: a scaled site plan, structural plans for the pool, a barrier plan showing how the pool will be enclosed, and an electrical plan covering bonding and the equipment disconnect.
What most pool permit applications include:
- Pool and spa design and construction fall under the residential code chapter that folds in the swimming pool and spa code, and permit review checks plans against that chapter (IRC R326).
- The site plan must show pool equipment such as pumps, filters, and heaters set back at least 36 inches from the outside of the required barrier (ISPSC 305.2.9).
- For an in-ground pool, engineered structural plans covering the shell and reinforcing steel, with the responsible structural engineer's license information, are a standard part of the submittal (per official pool submittal checklists).
- A barrier plan identifying the fence, pool structure, or dwelling wall that will enclose the pool must be submitted and must comply with the code's barrier chapter (ISPSC 305).
- Electrical plans must show the pool's equipotential bonding design, since the shell, perimeter surfaces, and metal fittings within 5 feet of the water must all tie into a common bonding grid (NEC 680.26).
- The electrical plan must also show a disconnecting means for the pool equipment that is readily accessible and within sight of the equipment (NEC 680.13).

Inspections and closing out your permit
Pool inspections track the concrete pour: the steel and bonding grid are checked before gunite or shotcrete goes in, bonding is checked again before decking is poured, and the permanent barrier and remaining electrical work are checked at final before the pool can be filled and used.
- Before gunite or shotcrete is sprayed, the inspector checks the rebar against the engineered plans and confirms the equipotential bonding wire is stubbed out and tied into the steel, since it will be buried in concrete afterward (NEC 680.26).
- A bonding inspection separately confirms coping, decking, ladders, handrail cups, and any other metal within 5 feet of the water are tied to the bonding grid, and it must pass before coping is installed (NEC 680.26).
- A temporary barrier at least 4 feet high must enclose the site from the moment excavation starts until the permanent barrier is finished, and inspectors check for it throughout construction (ISPSC 305.1.1).
- A pre-plaster inspection confirms the circulation equipment's electrical work is installed and all bonding is complete before the pool's interior finish goes on (NEC 680.26).
- At final inspection the permanent barrier is checked against the code's requirements and the equipment and cover-mechanism bonding must be complete before the pool can be filled and used (ISPSC 305, NEC 680.26).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the San Diego County permit portal or by phone at 858-565-5920.

- Where do you apply for a pool permit in San Diego County?
- You can apply through the San Diego County permit portal or contact the Planning & Development Services (PDS), Building Services Division directly. The links are listed on this page.
- Can a homeowner pull a pool permit themselves in San Diego County?
- Under California law (Business & Professions Code 7044(a)-(b); Business & Professions Code 7031.5): California exempts an owner-builder from contractor licensing when the owner personally performs the work, or uses only wage employees, on their own property and does not intend the improvements for sale. A homeowner may also directly hire licensed trade contractors for up to four single-family residences a year, or improve their own principal residence without a general contractor's license, as long as they have actually lived there for the 12 months before the work is finished. Selling a self-built structure within one year of completion creates a rebuttable presumption that it was built for sale, which defeats the exemption, and selling five or more structures within a year makes that presumption conclusive. Separately, every city or county that requires a building permit must also require the applicant to file a signed statement giving their contractor license number or the basis of their claimed exemption; a false or missing statement carries a $500 civil penalty. Confirm how San Diego County applies this before you apply.
