Dock, pier and float rules in Lewiston, Maine

Lewiston, Androscoggin County · Ordinances checked 2026-10-16 · Reviewed · 11 cited sections

Allowed with a permit

Yes, within limits. Lewiston's shoreland rules allow one dock, pier or other structure extending into the water per lot; a temporary (seasonal, in the water under 7 months a year) non-commercial dock can be no wider than 6 feet. A new permanent dock is allowed only if a temporary one isn't feasible and you have a Maine DEP permit. Apply to Planning & Code Enforcement for a City shoreland permit; ask whether a seasonal dock alone needs one.

Number per lotOne (a second only with twice the minimum shore frontage) [1]
Max width, temporary non-commercial dock6 feet [2]
Seasonal (temporary) dockIn the water less than 7 months in any 12; still a 'structure' under the shoreland rules [8]
Permanent piers and docksOnly if temporary isn't feasible and a DEP permit is obtained [4]
Structures on docksNot allowed unless they need direct water access [3]
Water setbackDoesn't apply to docks and piers [6]

What the City allows

Docks, piers and wharves are regulated by Lewiston's shoreland area standards in Article XII, Sec. 2 of the zoning code. The shoreland zone expressly includes any structure built on, over or abutting a dock, wharf or pier extending beyond the normal high-water line [5]. Only one structure extending below the normal high-water line of a water body or into a wetland is allowed per lot, unless the lot has at least twice the minimum shore frontage, in which case a second may be allowed as long as the lot isn't further divided [1]. Docks are exempt from the shoreline setback that applies to buildings, because they need direct access to the water [6].

Size and design

A dock must be no larger than needed for its purpose and consistent with the surrounding area, and a temporary pier, dock or wharf for non-commercial use can be no wider than 6 feet [2].

Permanent docks and structures on docks

New permanent piers and docks aren't permitted unless you clearly show the reviewing authority that a temporary dock isn't feasible and you've obtained a permit from the Maine Department of Environmental Protection under the Natural Resources Protection Act [4]. No new structure may be built on, over or abutting a dock unless it requires direct water access as an operational necessity [3].

Seasonal docks

The shoreland rules call a dock "temporary" if it stays in or over the water for less than 7 months in any 12 consecutive months [8]; anything longer is permanent. The shoreland definition of "structure" covers temporary as well as permanent structures [9], so a seasonal dock still has to meet the size and placement rules above. The code doesn't say outright whether putting in a seasonal dock by itself needs a shoreland permit; our reading is that it does, since a permit is required for placing any structure, but confirm with Planning & Code Enforcement.

Who issues the permit

Any activity requiring a permit in the shoreland zone needs a City shoreland permit first [7]. The shoreland section refers only to "the appropriate reviewing authority"; Article V makes the code enforcement official (Planning & Code Enforcement) the administrator of the zoning code unless the code says otherwise [10], and the City's Shoreland Zone Permit Application is filed with the Planning & Code Enforcement Office. Ask staff whether your dock also needs Planning Board review. The Article XI Land Use Table lists "water dependent uses, e.g. docks and marinas" as a use in only three districts (Riverfront, Mill and, as a conditional use, Resource Conservation) [11]; it doesn't say how a private dock that goes with a house is treated.

Lewiston's shoreland zone covers the Androscoggin River, No Name Pond, the Resource Conservation District and certain wetlands and brooks. We found no separate harbor, mooring or dock-registration ordinance.

Next steps

  1. Confirm your lot is in the shoreland zone and check its shore frontage.
  2. Plan a seasonal (temporary) dock no wider than 6 ft if possible; a permanent dock requires showing a temporary one isn't feasible.
  3. For a permanent dock, apply to the Maine DEP for a Natural Resources Protection Act permit.
  4. Submit a Shoreland Zone Permit Application with a site plan to Planning & Code Enforcement, 27 Pine St. (PlanningCode@lewistonmaine.gov, 207-513-3125).

Common questions

Do I need a permit to build a dock in Lewiston, Maine?
Usually, yes. Docks are in Lewiston's shoreland zone, and you apply to Planning & Code Enforcement for a City shoreland permit. Whether a seasonal dock by itself needs one isn't stated outright, so ask. A new permanent dock also needs a Maine DEP permit.
How wide can a dock be in Lewiston, Maine?
A temporary, non-commercial dock can be no wider than 6 feet, and any dock must be no larger than needed for its purpose. Only one dock, pier or other structure extending into the water is allowed per lot, unless the lot has at least twice the minimum shore frontage.
Can I put in a seasonal dock in Lewiston, Maine?
Yes, within the shoreland rules. A dock counts as temporary if it stays in the water less than 7 months in any 12. It is still a structure, so it must meet the size and placement rules. Check with Planning & Code Enforcement whether it needs a shoreland permit.
Can I build a permanent dock in Lewiston, Maine?
Only if you clearly show that a temporary dock isn't feasible and you have a permit from the Maine Department of Environmental Protection under the Natural Resources Protection Act. New structures on a dock aren't allowed unless they need direct water access.

State and federal rules for docks and piers

DEP permit (Natural Resources Protection Act): Building, repairing or altering a permanent structure in, on or over a great pond, river, stream or coastal wetland needs a DEP permit. "Permanent" means the structure stays in place more than 7 months in any 12-month period. A seasonal dock that comes out each year generally isn't a permanent structure.

State shoreland minimums (your town's ordinance applies these):

  • Only one pier, dock or wharf per lot, unless the lot has at least twice the minimum shore frontage.
  • A temporary, non-commercial dock on fresh water can be no wider than 6 ft.
  • A new permanent dock on fresh water is allowed only if a temporary dock isn't feasible and DEP has issued a permit.
  • No living space on or attached to a dock.

State-owned bottom: Below the low-water mark in tidal waters and in great ponds, the bottom belongs to the state. Permanent structures of any size, and large temporary ones, need a lease or easement from the Bureau of Parks and Lands. Non-permanent structures under 500 sq ft don't need one.

Federal and harbor rules: In tidal waters, docks and floats also need U.S. Army Corps of Engineers approval. Moorings are handled by your town's harbormaster under local ordinance (38 M.R.S. §7).
