Swimming pool rules in Hingham, Massachusetts
Yes, but Hingham's Board of Health must approve any residential pool in writing before you build it and inspect it before use. Any pool 2 feet deep or more needs a durable fence at least 6 feet high with a self-latching gate. Zoning has no pool-specific setback, but treated as a structure a pool must meet the district yard setbacks (for example 15 ft side/rear in Residence A, 20 ft in Residence B, C and E).
| Board of Health approval | Written approval before construction; inspection before use [1] |
| What counts as a pool | Over 2,450 gallons or 2 ft deep or more, in-ground or above-ground [3] |
| Fence height | At least 6 feet, fully enclosing the pool, self-latching gate [4] |
| Above-ground pools | Pool walls may be extended with fencing to a total of 6 ft; ladder must be enclosed [5] |
| Distance from septic | 20 ft from cesspool or leaching field; 10 ft from septic tank and cellar wall [6] |
| Zoning side/rear setback | 15 ft (Residence A); 20 ft (Residence B, C, E) [8] |
Board of Health approval
Hingham's Board of Health regulation (in effect February 16, 2023) says no one may build or install a residential pool, or make structural or operational changes to one, until the Board has approved it in writing; you must submit plans and specifications with the request [1]. When work is done you must notify the Board, and the pool can't be used until it's inspected [2]. The regulation covers pools over 2,450 gallons or at least 2 feet deep, in-ground or above-ground, together with bathhouses and equipment [3]. Pools also need an approved filtration and recirculation system and an approved water source, and must still meet building, plumbing and electrical codes.
Fencing
Any private pool 2 feet deep or more must be completely enclosed by a durable fence at least 6 feet high with a self-latching gate [4]. For an above-ground pool, you can instead extend the pool walls with fencing to a total height of 6 feet, with the ladder enclosed and a self-latching gate [5]. That's taller than the 48-inch minimum in the state building code; the local rule is stricter.
Location
The pool must be at least 20 feet from a cesspool or leaching field and 10 feet from a septic tank or cellar wall [6]. Under zoning, a "structure" is anything built at a fixed location on the ground, and in residential districts that includes pool heaters and filter equipment unless enclosed in a permitted accessory building [7]. Structures must meet the district's yard setbacks: in Residence A, 25 ft front and 15 ft side and rear; in Residence B and E, 35 ft front and 20 ft side and rear; in Residence C, 50 ft front and 20 ft side and rear [8].
Pool houses and flood zones
A pool house next to an in-ground pool may include bathing facilities, an exception to the usual accessory-building rule [9]. In the Floodplain Protection Overlay District, excavations or changes in watercourses to create ponds or pools for swimming need a Special Permit A1 from the Zoning Board of Appeals.

Massachusetts building code rules for pools
Under the State Building Code (780 CMR, 10th edition), residential pools, spas and hot tubs must meet the 2021 International Swimming Pool and Spa Code (ISPSC) as adopted in Massachusetts.
Permits:
- A building permit is needed for any pool except prefabricated pools under 24 inches deep.
- Plans for in-ground pools must be prepared by a registered design professional (an engineer or architect).
- Wiring must meet the Massachusetts Electrical Code (527 CMR 12.00), and gas pool heaters must meet the state plumbing and gas code (248 CMR).
Barrier (fence) requirements (ISPSC §305):
- The barrier must be at least 48 inches high, measured on the side away from the pool.
- The gap under the barrier can be no more than 2 inches over grass or gravel, or 4 inches over concrete.
- Pedestrian gates must open outward away from the pool, be self-closing and self-latching, and be able to take a lock.
- If a house wall forms part of the barrier, doors and low windows opening to the pool need an audible alarm (or another listed option).
- In-ground pool construction sites need temporary fencing at least 4 feet high from excavation until the permanent barrier is up.
- Spas and hot tubs with a lockable safety cover meeting ASTM F1346, and pools with a powered safety cover meeting that standard, are exempt from the barrier rules.
Local zoning still controls pool setbacks, and wetlands rules may apply near water.
