Rockport, Knox County · Ordinances checked 2026-10-01 · Reviewed · 12 cited sections

Allowed with a permit

Within Rockport's Shoreland Zoning Overlay (generally 250 feet from the ocean, coastal wetlands, great ponds, rivers and freshwater wetlands, and 75 feet from streams), new homes and accessory buildings must be set back at least 75 feet from the water (100 feet from GPA great ponds, 250 feet in Resource Protection) and need a permit, usually from the Code Enforcement Officer. Expanding an older building that's too close to the water is capped, and no part within 25 feet of the water may be expanded.

Where shoreland rules apply

Rockport's shoreland rules are Chapter 1400 of the Land Use Ordinance. They apply to land within 250 feet of a great pond, river, coastal wetland (including all tidal areas) or freshwater wetland, and within 75 feet of a stream [1]. The Official Shoreland Zoning Map divides this area into Resource Protection, Stream Protection and Other Shoreland Areas.

Setbacks and size limits

New principal and accessory structures must be at least 100 feet from GPA great ponds and rivers flowing to them, and 75 feet from other water bodies, tributary streams and wetlands; in Resource Protection the setback is 250 feet [2]. Piers, docks and other functionally water-dependent structures are exempt from the setback. Structures may be no taller than 35 feet [6], and non-vegetated surfaces (buildings, driveways, parking) may cover no more than 20% of the shoreland portion of the lot [7]. On a small nonconforming lot where a shed can't meet the setback, the CEO may allow one tool shed up to 80 square feet and 8 feet tall [5].

Expanding older buildings

No part of a structure within 25 feet of the water may be expanded, and an accessory structure closer to the water than the house can't be expanded [3]. For structures less than 75 feet from the water, the combined footprint is capped at 1,000 square feet or 30% more than on January 1, 1989, whichever is greater, and height at 20 feet or the existing height [4]. Stricter caps apply to homes entirely within 25 feet of the water, and different caps apply near GPA ponds and in Resource Protection.

Trees and vegetation

Within the 75-foot buffer (100 feet at GPA ponds), you may not create a cleared opening larger than 250 square feet, except one footpath up to 6 feet wide [8]. Selective cutting must leave a well-distributed stand of trees. Across the shoreland part of the lot, cleared openings for houses, driveways, lawns and septic may not exceed 25% of the area or 10,000 square feet, whichever is greater [9].

Permits

A permit is required before any regulated activity or before expanding, changing or replacing a structure [11]. A one- or two-family home needs a CEO permit in Stream Protection and Other Shoreland areas and, in Resource Protection, Planning Board approval as a conditional use, only if the strict conditions of §1416(5) are met [10][12].

Next steps

  1. Ask Rockport Planning & Codes (207-236-0989 ext. 2) to confirm your shoreland district on the Official Shoreland Zoning Map.
  2. Have a surveyor locate the normal high-water line or upland wetland edge and measure setbacks, plus your January 1, 1989 footprint if expanding.
  3. Submit a written application with a scaled site plan to the Code Enforcement Officer, or to the Planning Board in Resource Protection.
  4. Before cutting trees in the buffer, check the point-system and 250 sq ft opening limits with the CEO; work in or over the water may also need DEP and Army Corps permits.

Maine's shoreland zoning rules

Under the Mandatory Shoreland Zoning Act (38 M.R.S. §435–449), every town must enforce shoreland zoning at least as strict as the DEP's minimum guidelines (Chapter 1000).

What's in the shoreland zone: land within 250 ft of a great pond, river, tidal water, coastal wetland or most freshwater wetlands, and within 75 ft of a stream.

State minimum standards:

  • Setbacks for new buildings: 100 ft from great ponds classified GPA and from rivers that flow into them. 75 ft from other water bodies, tributary streams and wetlands.
  • Lot coverage: non-vegetated surfaces (buildings, driveways, etc.) are capped at 20% of the shoreland part of the lot in most districts.
  • Expanding an older building that sits too close to the water: no expansion of any part within 25 ft of the water. Within 75 ft, the total footprint is capped at 1,000 sq ft or 30% more than the footprint on Jan. 1, 1989, whichever is larger, and height at 20 ft or the existing height.
  • Vegetation buffer (within 100 ft of GPA ponds, 75 ft of other waters): no cleared opening over 250 sq ft, except one winding footpath up to 6 ft wide. Selective tree cutting only, with no more than 40% of tree volume removed in 10 years.
  • Total clearing: at most 25% of the shoreland lot area or 10,000 sq ft, whichever is larger, in most districts.

Work in or beside the water may also need a DEP permit.
