Swimming pool rules in Swampscott, Massachusetts
Swampscott's zoning bylaw treats pools and self-contained spas like accessory structures for setbacks: at least 5 feet from side and rear lot lines (or half the district's required setback, if larger) and no closer to the street than the front setback. Unlike sheds, there's no minimum distance from the house. Building permits and the safety barrier rules come from the State Building Code.
| Setback rule | Same as accessory structures, except the distance-to-house requirement [1] |
| Side/rear setback | Greater of 5 ft or 50% of the district's required setback [2] |
| Front | No closer to the street than the district's front setback [2] |
| A-3/A-4 required side and rear yards | 7.5 ft side, 20 ft rear (so about 5 ft side and 10 ft rear for a pool) [3] |
| Hot tubs | Self-contained spas follow the same setbacks [1] |
These rules come from the zoning bylaw version updated through the May 19, 2025 Town Meeting and may have changed since.
Setbacks
The section on accessory buildings and structures says all pools and self-contained spas follow the setback limits for accessory structures, except the required distance from the main building [1]. The accessory-structure rule puts the structure in the rear yard, no closer to a side or rear lot line than the greater of 5 feet or 50% of the district's required setback, and no closer to the street than the district's front setback [2]. Because the 10-foot separation from the house doesn't apply, a pool or spa can sit right next to your house or deck.
Typical numbers
In the A-3 and A-4 residence districts (and smaller A-1/A-2 lots) the required side yard is 7.5 feet and the rear yard is 20 feet [3], so a pool needs at least 5 feet from the side line and 10 feet from the rear line. Larger A-1 and A-2 lots have larger required yards (10 ft side and 25 ft rear on lots of about 20,000 sq ft or more; 15 ft side and 35 ft rear on A-1 lots of 30,000 sq ft or more), so the pool setback grows to half of those figures.
Above-ground vs. in-ground; coverage
The bylaw doesn't distinguish above-ground from in-ground pools. It also says a detached accessory building can occupy no more than 25% of the required rear yard; whether that cap applies to pools isn't clear from the text. The overall lot coverage and open space limits in Appendix A still apply.
Barriers and permits
The zoning bylaw has no pool fence rule. Barrier, permit and design requirements come from the State Building Code (see the state section). Pools near wetlands or in the coastal flood overlay may also need Conservation Commission review.

Next steps
- Find your district's required side and rear yards in Appendix A and plan the pool at least 5 feet (or half the setback) from those lines.
- Apply for a building permit with the Building Department (781-596-8857), with a plot plan showing setbacks and the barrier.
- If the yard is within 100 feet of a wetland, coastal bank or beach, contact the Conservation Agent (781-596-8829 ext. 1241) before applying.

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.
