Building near the water in York, Maine (shoreland zoning)
York's Shoreland Overlay District covers land within 250 ft of tidal waters, coastal wetlands and certain ponds, and you need a Shoreland Permit for most work there. New houses and accessory structures must be set back 100 ft from the normal high-water mark in the Resource Protection, Limited Residential and Mixed-Use subdistricts. Older buildings closer to the water can expand only within strict footprint and height caps. A vegetated buffer of 75 to 100 ft limits tree cutting and clearing.
| Shoreland zone | Within 250 ft of tidal waters, coastal wetlands and contiguous wetlands (plus listed ponds) [1] |
| Structure setback (Limited Residential) | 100 ft from the normal high-water mark (75 ft from 4-10 acre inland wetlands) [2] |
| Expansion within 25 ft of water | The part of a principal structure within 25 ft can't be expanded [3] |
| Building entirely within 25 ft | May expand to 800 sq ft or 30% over the Jan. 1, 1989 footprint; height 15 ft or existing [10] |
| Expansion within 75 ft | Total footprint capped at 1,000 sq ft or 30% over the Jan. 1, 1989 footprint; height 20 ft or existing [4] |
| Lot coverage | 20% in most subdistricts; 70% Mixed Use; 30% on existing lots under 12,000 sq ft [5] |
| Vegetated buffer | 100 ft (great ponds; York River, Cape Neddick River, Brave Boat Harbor) or 75 ft (other waters) [6] |
| Clearing in buffer | No cleared opening over 250 sq ft; one footpath up to 6 ft wide [7] |
| Tree cutting | No more than 40% of tree volume (4 in.+) in any 10 years [8] |
| Permit | Shoreland Permit required before building, expanding or changing a use [9] |
Where the rules apply
The Shoreland Overlay District, shown on two Town maps, includes tidal waters, coastal wetlands and contiguous inland wetlands, plus land within 250 ft of their normal high-water mark [1]. It also covers land within 250 ft of listed ponds such as Chases Pond and York Pond. Some shoreland setbacks can reach beyond 250 ft.
Setbacks
In the Limited Residential subdistrict, all principal and accessory structures and expansions must be 100 ft from the normal high-water mark or from the upland edge of coastal wetlands and inland wetlands of 10+ acres. The setback is 75 ft from inland wetlands of 4 to 10 acres [2]. Resource Protection and Mixed Use also require 100 ft (35 ft on Harris Island). Piers, docks and other structures that need direct water access are exempt. Coastal bluffs add their own setbacks, and the height limit is 35 ft.
Expanding older buildings
The part of a principal structure within 25 ft of the water can't be expanded [3]. The exception is a building that sits entirely within 25 ft: it may grow to 800 sq ft or 30% over its January 1, 1989 footprint, whichever is greater, and 15 ft or its existing height [10]. For structures within 75 ft, the combined footprint can't exceed 1,000 sq ft or 30% more than it was on January 1, 1989, whichever is greater, and height is capped at 20 ft or the existing height [4]. Structures within the 100-ft setback get a 1,500 sq ft / 25 ft cap. Additions must go on the side away from the water, and the approved plan must be recorded at the Registry of Deeds.
Lot coverage
All structures and non-vegetated surfaces, including driveways and parking, can't exceed 20% of the shoreland part of the lot in most subdistricts, 70% in Mixed Use, or 30% on existing lots under 12,000 sq ft [5].
Trees and vegetation
A vegetated buffer must be kept within 100 ft of great ponds and of the tidal York River, Cape Neddick River and Brave Boat Harbor, and within 75 ft of other waters and wetlands [6]. In the buffer, no cleared opening can exceed 250 sq ft, and only one footpath up to 6 ft wide is allowed [7]. Selective cutting must leave a well-distributed stand, and no more than 40% of tree volume may be removed in 10 years [8]. You must submit before-and-after photos of shoreline vegetation.
Permits
You need a Shoreland Permit to build, expand, change or replace a use or structure [9]. Depending on the use, the CEO or the Planning Board issues it.

Next steps
- Check the Town's Shoreland Overlay District maps (Town Clerk) to see if your lot and which subdistrict it is in.
- Have a surveyor locate the normal high-water mark or wetland edge and measure setbacks, existing footprint and lot coverage.
- Take preconstruction photos of the shoreline vegetation and apply for a Shoreland Permit at the York Code Enforcement Office.
- For expansions of nonconforming buildings, have a Maine-licensed architect, engineer or surveyor prepare a sealed plan to record after approval.

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.
