Dixmont, ME Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 15(B)(4) of the Dixmont Shoreland Zoning Ordinance limits non-vegetated surfaces to twenty (20) percent of the portion of the lot located within the shoreland zone. The list of what counts is open: structures, driveways, parking areas, and other areas from which vegetation has been removed. Naturally occurring ledge and rock outcroppings are not counted for lots that were recorded on March 24, 1990, and have been in continuous existence since that date. The cap does not apply to public boat launching facilities.

Section 3 sets the reach of the ordinance: all land within 250 feet, horizontal distance, of the normal high-water line of great ponds, within 250 feet of the upland edge of a freshwater wetland, and within 75 feet of the normal high-water line of a stream. Land outside those bands has no shoreland coverage cap. Section 15 sits beside other dimensional rules. New principal and accessory structures must be set back at least one hundred (100) feet from the normal high-water line of great ponds and seventy-five (75) feet from other water bodies, tributary streams or wetland edges, and 250 feet in the Resource Protection District. Structures cannot exceed thirty-five (35) feet in height. A residential lot needs 40,000 square feet and 200 feet of shore frontage.

Mobile home parks carry a separate coverage rule. Section 4(E) of the Mobile Home Park Ordinance says all buildings on the lot, including accessory buildings and structures, open decks and parking spaces, shall not cover more than 50% of the lot area. Under Section 3(F)(1), the CEO can allow an increase of up to ten percent (10%) in existing parks for new decks and accessory structures, after findings that strict conformity would leave them substantially unusable or impractical. The Board of Appeals reviews a denial. Site Plan Review Section 9.5 also keeps parking spaces, access drives and impervious surfaces at least five (5) feet from side and rear lot lines.
