Swimming pool rules in Andover, Massachusetts
Private pools are allowed in Andover in rear and side yards, but not front yards. They must be at least 10 feet from the rear property line and meet the district's side-yard setback (20, 25 or 30 feet in SRA, SRB and SRC). Near wetlands, pools and pool decks need at least 35 feet from the resource area. State code requires a building permit and a 48-inch barrier.
| Where on the lot | Rear or side yard; not the front yard [1] |
| Rear property line setback | 10 ft [1] |
| Side setback | District side-yard minimum: 20 ft (SRA), 25 ft (SRB), 30 ft (SRC) [2] |
| What counts as a pool | In-ground or above-ground; excludes portable pools under 8 ft across holding 1 ft of water or less [3] |
| Wetlands setback (pools and pool decks) | 35 ft (60 ft in Watershed Protection Overlay; 100 ft from vernal pools) [4] |
| Conservation Commission filing fee (NOI, single-family pool) | $110 per activity [5] |
The zoning rules here come from the 2022 recodified Zoning Bylaw (adopted 2023), the newest full text we have, and may have changed since.
Where a pool can go
Andover's Zoning Bylaw treats private pools, tennis and sports courts as accessory uses allowed in rear and side yards, but not front yards, in all districts [1]. A pool must be at least 10 feet from any rear property line, and it must meet the district's minimum side-yard setback. In the Table of Dimensional Requirements the side yard is 20 feet in Single Residence A, 25 feet in Single Residence B and 30 feet in Single Residence C [2]. Pools count as "structures" under the bylaw, so they also count toward any coverage and setback rules that apply to structures.
What counts as a pool
The bylaw covers all swimming and wading pools, in-ground or above-ground. Only small portable pools are excluded: less than 8 feet across and holding no more than 1 foot of water [3].
Near wetlands
The Conservation Commission's regulations set minimum distances for swimming pools and pool decks [4]:
- 35 feet from any bank, wetland, marsh, pond, river, stream or land under water
- 60 feet from resource areas in the Watershed Protection Overlay District
- 100 feet from a vernal pool
If the pool is within 100 feet of a resource area (200 feet of a river), you'll need to file with the Commission. A Notice of Intent for work on a single-family lot, such as a pool, has a local bylaw filing fee of $110 per activity [5] (fee schedule effective June 18, 2013; confirm the current amount).
Permits and fencing
The local bylaw text we reviewed doesn't set its own pool fence rule. The state building code requires a building permit for most pools and a barrier at least 48 inches high with self-closing, self-latching gates; see the state rules on this page. Hot tubs aren't addressed separately in the local text.

Next steps
- Site the pool in the rear or side yard, at least 10 feet from the rear lot line and outside the district's side-yard setback.
- If the pool or deck is within 100 feet of a wetland, pond or stream (200 feet of a river), contact the Andover Conservation Commission and file before building.
- Apply for a building permit from the Building Division (978-623-8620) with a plot plan; in-ground pools need plans from a registered design professional under state code.
- Plan a compliant 48-inch barrier with self-closing, self-latching gates, plus separate electrical permits.

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.
