Rockport, Knox County · Ordinances checked 2026-10-01 · Reviewed · 8 cited sections

Allowed with a permit

Yes, but Rockport requires a permit from the Code Enforcement Officer for any new structure, with no small-shed exemption in the Land Use Ordinance. One shed of up to 150 square feet and 12 feet tall may sit inside the side or rear setback if it stays at least 6 feet from the property line; larger accessory buildings must meet the district's full setbacks (for example 8 feet in the Village districts and 15 feet in the Residential District).

Do you need a permit?

Section 601 says no structure may be constructed, moved, added to or substantially renovated without a permit issued by the Code Enforcement Officer [1]. The Land Use Ordinance has no square-footage threshold below which a shed is exempt, so plan to apply even for a small prefab shed. Accessory structures are a permitted use in every zoning district [6].

Sheds inside the setback

Rockport has a special allowance for small accessory buildings. In all districts, woodsheds, garden sheds, tool houses and similar accessory buildings may be placed within the side and rear yard setbacks if total ground coverage is 150 square feet or less and building height is 12 feet or less [2]. The shed may not store more than 5 gallons of flammable liquids or gases, no part of it may be closer than 6 feet to the property line, and only one accessory structure per lot may use this allowance [3]. The allowance covers side and rear yards only, not the front yard.

Larger sheds, garages and barns

Anything bigger must meet the regular district setbacks in Section 918. Minimum side and rear setbacks are 8 feet in the Harbor Village (901) and Village (902) districts, 15 feet in the Residential Coastal (903), Residential (904) and most other districts, 0 in Downtown and 25 feet in Industrial [4]. Maximum building height is 34 feet in every district, and lot coverage caps (60% in most districts, 33% in Residential Coastal) apply [5]. Lot coverage counts all structures plus driveways, parking areas and patios, so a shed adds to it [8]. In the Traditional Village District, garages must be set back at least 10 feet farther from the front property line than the front of the house [7].

Shoreland zone

If your lot is within the Shoreland Zoning Overlay, accessory structures must also meet the Chapter 1400 water setbacks and need CEO or Planning Board approval depending on the shoreland district.

Next steps

  1. Measure your side and rear setbacks from a survey or plot plan and decide whether the shed fits the 150 sq ft / 12 ft / 6 ft-from-line allowance.
  2. Check whether your lot is in the Shoreland Zoning Overlay (ask Planning & Codes, 207-236-0989 ext. 2).
  3. Apply to the Code Enforcement Officer for a building permit with a sketch showing the shed's size, height and distances to property lines.
  4. Schedule the CEO's inspection; structures needing a building permit also need a Certificate of Occupancy.

Maine building code and shoreland rules for sheds

Building code (MUBEC): The Maine Uniform Building and Energy Code adopts the 2021 International Residential Code, effective April 7, 2025. It must be enforced in towns with more than 4,000 residents. Smaller towns may choose to enforce it, but they can't adopt any other building code.

  • Maine's version of the code says building permits are required "where required by municipal ordinance," and towns can exempt more work from permits.
  • The residential code exempts small one-story detached accessory buildings from a building permit. Under the IRC that means up to 200 sq ft.
  • Being exempt from a building permit doesn't exempt you from zoning. Setbacks, lot coverage and any land-use permit still apply. Check with your code officer.

Shoreland zone: A shed is a "structure" under the state shoreland rules, so it must meet the water setbacks: generally 100 ft from GPA great ponds and 75 ft from other waters and wetlands. It also counts toward the 20% lot-coverage cap. On a small nonconforming lot where a shed can't meet the setback, the code officer may allow one shed up to 80 sq ft and 8 ft tall, with no utilities. It has to be as far from the water as practical and never closer than the house.
