Swimming pool rules in Lincoln, Massachusetts
Lincoln has no pool-specific bylaw, but its zoning bylaw counts swimming pools as structures. A pool must be at least 50 feet from the street line and at least 20 feet from side and rear lot lines. Pools are barred from any vegetated wetland buffer strip the Conservation Commission requires. Permits and fence or barrier rules come from the state building code (shown separately).
| Pools are structures | Yes, "swimming pools" are listed in the definition of structure [1] |
| Setback from street line | 50 ft [2] |
| Setback from side and rear lot lines | 20 ft or the structure's height, whichever is greater [3] |
| Wetland buffer strip | Swimming pools prohibited [4] |
| Local pool fence rule | None in the bylaws; state barrier code applies [1] |
Zoning setbacks
Lincoln's zoning bylaw has no section devoted to pools. Its definition of a structure includes swimming pools, along with tennis courts and similar features [1]. That brings a pool under the Section 13.4 accessory-structure setbacks. A pool can be no closer than 50 feet to the street line [2]. It can be no closer to a side or rear lot line than 20 feet, or than its height above ground if that's greater [3]. In practice the 20-foot figure controls for an in-ground pool or a typical above-ground pool. The Board of Appeals can relax these setbacks by special permit.
Near wetlands
Many Lincoln lots are near wetlands, ponds or streams. If the Conservation Commission approves work within 100 feet of a wetland, or 200 feet of a river or perennial stream, it may require a continuous vegetated buffer strip at least 50 feet wide (100 feet for rivers and perennial streams). On lots created after March 29, 2003, the Commission won't permit permanent structures anywhere within 100 feet of a wetland (200 feet of a river or perennial stream). Swimming pools are specifically prohibited in that strip [4]. The Commission generally discourages any structures in the buffer zone. Contact it before designing a pool on a lot with wetlands.
Fences, permits and hot tubs
The zoning bylaw has no pool-barrier provision and doesn't mention hot tubs or spas. The state building code governs building permits, the 48-inch barrier, gate latches and safety covers; see the state rules on this page. A pool fence that runs within 20 feet of a lot line along a road or public trail also needs a Lincoln fence permit. If it's over 3½ feet tall there, it needs Planning Board approval as well. Pool equipment and electrical work need the usual trade permits.

Next steps
- Lay out the pool at least 50 ft from the street line and at least 20 ft from side and rear lot lines.
- If the pool is within 100 ft of a wetland or pond (200 ft of a river or perennial stream), contact the Conservation Commission before designing it.
- Apply to the Building Department (781-259-2613) for a building permit, with a plot plan showing setbacks and the barrier design.
- If the pool fence runs within 20 ft of a lot line bordering a road or public trail, get a fence permit as well (plus Planning Board approval if it's over 3½ ft).

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.
