Dock, pier and float rules in Andover, Massachusetts
A private dock on an Andover pond, lake or river needs a permit from the Andover Conservation Commission, because the town's Wetlands Protection Bylaw covers building on land under water and banks. Dock filings cost $4 per linear foot ($100 minimum). Boat docks aren't allowed on Haggett's Pond or Fish Brook, which are drinking-water sources.
| Town approval | Conservation Commission permit (building on banks or land under water is regulated) [1] |
| Filing fee for docks/piers | $4 per linear foot; $100 minimum, $2,000 maximum [2] |
| Haggett's Pond and Fish Brook | Boat docks and landings not permitted [3] |
| Permit term | Expires 3 years after issuance (renewable) [4] |
These rules come from the Wetlands Protection Bylaw (Aug 2021 printout), the Commission's regulations (revised through July 2026) and, for the overlay district, the 2022 recodified Zoning Bylaw, which may have changed since.
Conservation Commission permit
Andover's Wetlands Protection Bylaw bars anyone from filling, dredging, building on or altering any bank, pond, lake, river, stream or land under water, or land within 100 feet of one, without Conservation Commission approval [1]. A dock, pier or float sits on the bank and over land under water, so it needs a Commission permit. The Commission's fee schedule has a specific category for work on docks and piers, at $4 per linear foot, with a $100 minimum and $2,000 maximum [2] (the "17 & 18" in the quoted line are footnote markers).
You file a Notice of Intent with plans, notify abutters (certified mail, hand delivery or certificate of mailing), and attend a public hearing. The Commission can approve with conditions or deny. The permit must be recorded at the Registry of Deeds before work starts and expires after three years unless renewed [4]. The bylaw and regulations don't set size limits or seasonal-versus-permanent rules, so the Commission decides those case by case.
Watershed Protection Overlay
Zoning allows boat docks and landings in the Fish Brook/Haggett's Pond Watershed Protection Overlay District, except on Haggett's Pond and Fish Brook themselves [3]. Elsewhere in that overlay, zoning also restricts new structures within 50 feet of water bodies, so ask the Planning Division how that applies to a dock on another pond or stream in the district.
State and federal approvals
The local documents don't cover state or federal permits. A dock on a great pond or navigable river may also need a Chapter 91 license from MassDEP, and possibly U.S. Army Corps of Engineers approval (see the state rules on this page).

Massachusetts state rules for docks and piers
A private dock in Massachusetts usually needs several layers of approval beyond local zoning.
Chapter 91 waterways license (MassDEP): any structure, regardless of size, permanent or seasonal, in tidal waters, in a great pond (a pond over 10 acres in its natural state), or in certain navigable rivers needs Chapter 91 authorization (M.G.L. c. 91; 310 CMR 9.00). For small residential docks there are simpler routes:
- a General License certification for pile-supported residential docks, piers, ramps and floats with no fill or dredging, outside ACECs and Designated Port Areas (310 CMR 9.29)
- a Simplified License for residential docks up to 600 sq ft below the high-water line (310 CMR 9.10)
Licenses must be recorded at the Registry of Deeds, and Chapter 91 protects public rights to fish, fowl and navigate.
Conservation Commission: dock work in or near wetlands, banks or land under water needs an Order of Conditions under the Wetlands Protection Act (c. 131, §40).
Harbormaster: bottom-anchored moorings, floats and rafts (no pilings) can be authorized by an annual permit from the local harbormaster instead of a Chapter 91 license (c. 91, §10A). Mooring fees can't discriminate based on residence.
U.S. Army Corps of Engineers: work in navigable waters may also need federal approval. Small private piers and floats are often covered by the Corps' Massachusetts General Permits, which can involve self-verification or pre-construction notification.
