Quick answer
The county's adopted California Residential Code Section R105.2 list exempts only prefabricated swimming pools that are less than 24 inches deep, so any deeper or in-ground residential pool needs a building permit. The same 24-inch line runs through the county's swimming pool ordinance: Ordinance Code Section B18-1 defines a private swimming pool as an artificial body of water at a residence with any depth in excess of 24 inches, above or below grade and temporary or permanent, and Section B18-2 requires that pool to be completely enclosed by a fence, wall or other structure at least 5 feet high with no opening, hole or gap wider than 4 inches. Section B18-5 makes the enclosure a structure under the county building code and withholds final inspection until the enclosure and gate requirements are met. Zoning Ordinance Section 4.20.020.J requires the pool and its filters, pumps and appurtenant machinery to sit at least 5 feet from any property line or right-of-way.
Typical threshold: depth of a prefabricated swimming pool.

How to apply in Santa Clara County
In Santa Clara 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).
- For Santa Clara County, 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).
- For Santa Clara County, 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).
- For Santa Clara County, 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
In Santa Clara County, 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.
- In Santa Clara County: 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).
- In Santa Clara County: 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).
- In Santa Clara County: 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).
- In Santa Clara County: 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).
- In Santa Clara County: 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 Santa Clara County permit portal or by phone at 408-299-5700.

- Can a homeowner pull a pool permit themselves in Santa Clara County?
- Under California law (Business & Professions Code 7044(a)-(b); Business & Professions Code 7031.5): California exempts an owner from contractor licensing under section 7044 when they personally perform all the work on their own property, or any work they do not perform themselves is done by their own employees paid only wages, and none of the improvements are intended or offered for sale. It also exempts an owner who directly contracts with licensed contractors for each trade, as long as no more than four of the single-family residential structures involved are intended or offered for sale in a calendar year; this route does not apply if the owner instead contracts with a general contractor for the construction. A homeowner may also improve their own principal residence without a license, as long as the work is done before any sale, they have actually resided there for the 12 months before completion, and they have not used this exemption on more than two structures more than once in any three-year period. 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 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 civil penalty of up to $500. Confirm how Santa Clara County applies this before you apply.
