When a permit is usually needed
Before installing any swimming pool over 24 inches deep in Bellevue
What your pool permit must meet in Washington
Washington's 2021 Residential Code (WAC 51-51, effective statewide March 15, 2024) requires backyard swimming pools, spas, and hot tubs at single-family and duplex homes to be designed and built to the 2021 International Swimming Pool and Spa Code, incorporated by direct statewide reference rather than left to local option.
- The design and construction of swimming pools, spas, and other aquatic recreation facilities must comply with the 2021 International Swimming Pool and Spa Code whenever the facility falls into one of three defined residential categories (WAC 51-51-0327).
- That mandatory ISPSC standard covers pools for the sole use of a single-family dwelling's residents and guests, the sole use of a resident-owned duplex, or a facility used exclusively for medical physical therapy under a licensed practitioner's supervision (WAC 51-51-0327).
- Any other water recreation facility outside those residential categories is regulated under separate Washington Department of Health rules, not the Residential Code (WAC 246-260; WAC 51-50-3109).
Based on 2021 International Swimming Pool and Spa Code (ISPSC), incorporated by WAC 51-51-0327 into the 2021 Washington State Residential Code. Read the code. Local amendments can be stricter; confirm the current requirement with your office before you build.

How to apply in Bellevue
In Bellevue, 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 Bellevue, 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 Bellevue, 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 Bellevue, 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 Bellevue, 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 Bellevue: 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 Bellevue: 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 Bellevue: 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 Bellevue: 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 Bellevue: 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 Bellevue permit portal or by phone at (425) 452-4898.

- Can a homeowner pull a pool permit themselves in Bellevue?
- Under Washington law (RCW 18.27.090(11), (12); RCW 19.28.261(1); RCW 18.106.150(1)): Washington lets homeowners do their own construction work, including the licensed trades, on property they own. RCW 18.27.090(12) exempts any person working on his or her own property from contractor registration, but the exemption does not apply if you do contractor type work for the purpose of selling, demolishing, or leasing the property, and the separate owner exemption in RCW 18.27.090(11) is lost if you sell or lease improved property owned less than 12 months. For electrical work, RCW 19.28.261 lets you wire your own residence, farm, or place of business without an electrician license, unless the work is on construction of a new building intended for rent, sale, or lease, or on property offered for sale within 12 months after you obtained it. RCW 18.106.150(1) gives the same kind of exemption for plumbing work at your own residence, farm, or place of business. These exemptions waive the license, not the permit: an owner doing electrical work still buys an L&I electrical work permit and passes inspection (WAC 296-46B-901), and building and plumbing permits still come from your local building department. Confirm how Bellevue applies this before you apply.
