Shed Installation · Penobscot County, Maine
In Penobscot County, whether a Shed Installation needs a permit is set locally, and the county does not publish a single fixed threshold.
Bangor, the county seat, sets its own building-permit trigger at just 100 square feet, half the more common statewide 200-square-foot MUBEC exemption most Maine towns use. Penobscot County is unusual in having significant unorganized territory, land with no local government, where the state's Land Use Planning Commission rather than any town handles permitting; as of a rule that took effect at the end of January 2025, an accessory structure built without a permit in these unorganized areas must stay under 750 square feet, cannot expand by more than 750 square feet over any two-year period, and the owner must now file a notification form with the state confirming compliance with setback standards, which the commission sets at 100 feet from lakes or rivers and 75 feet from other water features or wetlands. The reliable answer comes from Brewer Code Enforcement. Zoning setbacks apply either way.
