What your pool permit must meet in Virginia
Virginia's 2021 Uniform Statewide Building Code makes the 2021 International Swimming Pool and Spa Code the governing construction standard for swimming pools statewide, and a companion Virginia Residential Code amendment adds its own glazing-safety rule for pools, spas, and hot tubs at one- and two-family homes.
- Virginia's building code incorporates the 2021 International Swimming Pool and Spa Code (ISPSC) by reference as an enforceable statewide standard (13VAC5-63, referenced standards).
- Swimming pools, swimming pool enclosures, and aquatic recreational facilities must comply with the applicable provisions of the ISPSC under Virginia's amendment to the model building code (13VAC5-63-336, Section 3109.1).
- A Virginia-specific residential amendment requires safety glazing within 60 inches of the water's edge of a hot tub, spa, or indoor or outdoor swimming pool, treating that zone as a hazardous glazing location (VRC R308.4.5, 13VAC5-63-210).
Based on 2021 Virginia Uniform Statewide Building Code, 13VAC5-63-336 (Section 3109.1) and 13VAC5-63-210 (VRC R308.4.5), incorporating the 2021 ISPSC. Read the code. Local amendments can be stricter; confirm the current requirement with your office before you build.

How to apply in Fairfax 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 Fairfax County permit portal or by phone at 703-222-0801.
