Cumberland County, ME Parking Rules: Driveway Rules (2026)

There is no Cumberland County code provision addressing residential driveway construction, parking on driveways, or driveway aprons. A new or modified driveway onto a state or state-aid highway in Cumberland County requires an entrance permit from the Maine Department of Transportation under Me. Rev. Stat. tit. 23 § 1851 et seq. and the MaineDOT Rule Chapter 299 (Driveway and Entrance Rules), which set minimum sight-distance, drainage, and spacing standards. On local town ways, driveway permits and design standards (typical minimum apron width 10–12 ft, maximum grade 10%, paved transition where the street is paved) are set by each municipality's public-works department or planning board. On-driveway parking of recreational vehicles, boats, and commercial vehicles is regulated only by municipal zoning — for example, Portland Code Ch. 14 limits commercial-vehicle storage in residential zones — and not by any county rule. The statewide ADU statute (Me. Rev. Stat. tit. 30-A § 4364-A, LD 2003) further caps off-street parking demand at no more than one additional space for an accessory dwelling unit attached to a single-family home, overriding stricter local driveway/parking minimums.
