When a permit is usually needed
Before installing any residential pool that can hold more than 24 inches of water
What pool permit costs in Boston
Pools need a Use of Premises Permit at a $50 primary fee per the ISD fee schedule effective 5/15/2023, with in-ground pools also needing Building and Electrical trade permits.
How to apply in Boston
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 Boston permit portal or by phone at (617) 635-5300.

- Can a homeowner pull a pool permit themselves in Boston?
- Under Massachusetts law (780 CMR R105.3; 780 CMR 110.R5.1.3.1 (10th ed.); M.G.L. c. 142, s. 3; M.G.L. c. 141, s. 1A): Yes for the building permit itself: 780 CMR R105.3 says 'the owner or authorized agent shall file a permit application.' The construction supervisor license (CSL) rules contain an explicit homeowner exemption at 780 CMR 110.R5.1.3.1: 'Any homeowner performing work for which a building permit is required shall be exempt from the licensing provisions of 780 CMR 110.R5, provided that if a homeowner engages a person(s) for hire to do such work, then such homeowner shall act as supervisor.' 'Homeowner' is defined as a person who owns a parcel on which he or she resides or intends to reside with a one- or two-family dwelling; a person who constructs more than one home in a two-year period does not qualify. The exemption does not extend to the trades: plumbing and gas work requires licensure under M.G.L. c. 142, s. 3, which contains no homeowner exemption, and the electrician licensing exemptions in M.G.L. c. 141, s. 1A likewise do not include homeowners. Confirm how Boston applies this before you apply.
