• Accessory Dwelling Units (ADUs)
  Yes. Rockport allows one accessory dwelling unit on any lot where a single-family home is the principal building, inside the house, attached, or as a new detached building, with a building permit from the Code Enforcement Officer. The ADU must be at least 190 square feet, a detached one can't be taller or larger than the main house, and the ordinance currently requires the owner to live in either the house or the ADU.Allowed with a permit
• Backyard Chickens
  Rockport's Land Use Ordinance lets you keep animals other than household pets, which would include chickens, only on lots of at least 40,000 square feet (about 0.92 acre), with the enclosure at least 25 feet from every property line. A 2025 state law bars towns from prohibiting hens on residential property, so ask the Code Enforcement Officer how Rockport applies the lot-size rule to smaller lots.Restricted
• Short-Term Rentals (Airbnb / VRBO)
  Rockport's Land Use Ordinance defines short-term rentals (stays of less than 30 consecutive days) but, in the documents we reviewed, sets no STR registration, license, fee, cap or owner-occupancy rule. Short-term rental units count as Rental Housing Units, which the Code Officer or Fire Chief inspects for habitability and life safety when the property is sold or a tenant complains.Allowed
• Fences
  Rockport's Land Use Ordinance sets no height limit or property-line setback for residential fences, because it expressly says a fence is not a "structure." That means the structure setbacks and the building-permit requirement, which apply to structures, don't cover an ordinary fence; confirm with the Code Enforcement Officer before building a very tall fence or one near a road.Allowed
• Sheds & Accessory Buildings
  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).Allowed with a permit
• Burn Permits & Backyard Fires
  Yes, with a permit. Rockport requires a burn permit to burn wood or leaves from your property, and the Fire Department issues permits only online through the free Maine Open Burn Permit service. Campfires for cooking or heat don't need a permit, but backyard fire pits may be used only on Class 1 and 2 fire-danger days.Allowed with a permit
• Home-Based Businesses
  Yes. Home occupations are a permitted use throughout Rockport's residential and village districts, but you need a use permit from the Code Enforcement Officer and must meet the Section 811 standards: the business must be inside the home or an accessory building, use no more than 50% of the floor area, and involve no more than six people, at most two from outside the family. Projects generating more than 20 business vehicle trips a day need Planning Board site plan review.Allowed with a permit
• Swimming Pools
  Rockport's Land Use Ordinance has no specific rules for residential swimming pools or hot tubs, including fence or barrier rules. A pool built in or on the ground fits the ordinance's broad definition of a "structure," so it likely needs a permit from the Code Enforcement Officer and must meet your district's setbacks, and Rockport enforces the state building code (MUBEC), which the CEO applies to pools.Not specifically regulated
• Building Near the Water (Shoreland Zoning)
  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.Allowed with a permit
• Docks, Piers & Floats
  Yes, but a pier, wharf or float in Rockport needs a permit from the Rockport Planning Office after review: the Harbor Committee and Harbormaster review pier applications and make recommendations to the Planning Board, which reviews them under the shoreland rules. Each lot is limited to one pier or wharf, a private residential pier can be no wider than 6 feet, and piers can't extend more than 150 feet beyond mean high water (or to mean low water, if shorter).Allowed with board review
