Dock, pier and float rules in Dover, Massachusetts
A dock, pier or float on a Dover pond or river needs a permit from the Conservation Commission, because any building on or within 100 feet of a pond or river requires one under the Wetlands Protection Bylaw. The Commission's filing fee for dock work is $4 per linear foot, with a $100 minimum and $2,000 maximum. Dover's rules set no dock size limits; the Commission sets conditions case by case.
| Town approval | Conservation Commission permit [1] |
| Jurisdiction | Within 100 ft of ponds/lakes; 200 ft of rivers and perennial streams [2] |
| Filing fee | $4 per linear foot ($100 min, $2,000 max) [3] |
| Work in the water | Only for a water-dependent use or permitted crossing [4] |
Town approval
Dover is an inland town with no separate dock bylaw. Docks are regulated under the Dover Wetlands Protection Bylaw (Chapter 181), which requires a Conservation Commission permit for any work that would "alter or build upon" a lake, river or pond, land under the water, or land within 100 feet of them [1]. For rivers and perennial streams, the permit requirement extends to 200 feet [2]. A dock, pier or float on any Dover water body falls within this rule.
Fees and review
The Commission's regulations (Chapter 263) list "work on docks, piers, revetments, dikes, etc. (coastal or inland)" as a Category 5 project. The filing fee is $4 per linear foot, with a $100 minimum and $2,000 maximum [3]. Work on land under a pond or river is allowed only if it is directly associated with a permitted crossing or a "water dependent use" as defined in the regulations, and it must not harm water quality, flow capacity, erosion control or wildlife habitat [4]. The definition covers facilities that need to be in or next to inland waters, including water-based recreational uses, so the Commission decides whether a given dock qualifies. Any approved permit must be recorded at the Registry of Deeds before it takes effect [5].
Size limits and seasonal docks
The bylaw and regulations we reviewed don't set dock dimensions or treat seasonal floats differently from permanent piers. The Commission sets conditions case by case. Building in the buffer zone (the access path, for example) is also subject to the Commission's structure and disturbance setbacks.
State and federal permits
A dock on a great pond (over 10 acres in its natural state) or a navigable river may also need a Chapter 91 waterways license from MassDEP and Army Corps of Engineers approval. Dover's documents don't address these permits, so check with the Commission.

Next steps
- Contact the Dover Conservation Commission to discuss the dock before you design it.
- File a permit application (Notice of Intent form) with plans showing the dock's length and construction, and pay the $4 per linear foot fee.
- Ask MassDEP whether the water body is a great pond or navigable river that requires a Chapter 91 license.
- Record the Commission's permit at the Registry of Deeds before installing.

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.
