What your pool permit must meet in Maryland
Maryland regulates residential swimming pools and spas under a dedicated statewide code, the Maryland Swimming Pool and Spa Standards, rather than through the IRC used for the rest of the house. That chapter currently incorporates the 2024 International Swimming Pool and Spa Code.
- The state runs a dedicated pool and spa code: the 2024 International Swimming Pool and Spa Code (ISPSC) is incorporated by reference in the Maryland Swimming Pool and Spa Standards (COMAR 09.12.56.03).
- The Standards apply to every pool or spa whose building-permit application is received by a local jurisdiction on or after December 31, 2023 (COMAR 09.12.56.02).
- Residential (non-public) pools must be surrounded by a barrier that complies with the ISPSC barrier provisions, Sections 305.2.1 through 305.7 (COMAR 09.12.56.05).
Based on 2024 ISPSC, adopted via COMAR 09.12.56 Maryland Swimming Pool and Spa Standards. Read the code. Local amendments can be stricter; confirm the current requirement with your office before you build.

How to apply in Montgomery County
In Montgomery 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 Montgomery 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 Montgomery 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 Montgomery 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 Montgomery 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 Montgomery 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 Montgomery 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 Montgomery 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 Montgomery 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 Montgomery 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 Montgomery County permit portal or by phone at 240-777-0311.

- Can a homeowner pull a pool permit themselves in Montgomery County?
- Under Maryland law (Md. Code, Bus. Occ. and Prof. 12-301(b), 6-607(1); Public Safety 12-505): It depends on the trade and the county. Plumbing: state law exempts an individual who personally provides plumbing services in their own residence, but homeowners may not make final connections between the residence and public or private water supply or disposal systems, and Baltimore County plus the WSSC-area counties are largely carved out of the state plumbing title. Electrical: the Maryland Electricians Act prohibits providing electrical services for compensation without a license; it has no express homeowner exemption, so uncompensated work on one's own home falls outside the licensing prohibition, but each county decides whether it will issue an electrical permit to an unlicensed homeowner. Building permits are issued by local jurisdictions, which set their own owner-applicant rules. Confirm how Montgomery County applies this before you apply.
