Cumberland County, ME Parking Rules: RV & Boat Parking (2026)

Maine counties have no zoning or general police-power ordinance authority over organized municipalities (see 30-A MRS §3001 home-rule grant to municipalities; Maine LUPC, 12 MRS §685-A, handles only the Unorganized Territory). Cumberland County publishes no code of ordinances — only a Charter and Commissioner bylaws — and therefore imposes no county-wide rule on RV, camper, motorhome, boat, or trailer parking on private lots, in driveways, or on the street. The applicable rules come from each of Cumberland County's 28 municipalities (Portland, South Portland, Westbrook, Scarborough, Gorham, Brunswick, Falmouth, Windham, Cape Elizabeth, Freeport, Cumberland Town, Yarmouth, Standish, Bridgton, etc.), and from two state baselines: (1) 29-A MRS §1854 requires the property owner or storage facility holding an abandoned vehicle (including RVs and trailers) to notify the Maine Secretary of State within 14 days of the earliest unpaid-charge date for repair/storage situations; (2) the mandatory Shoreland Zoning Act, 38 MRS §435 et seq., applies a 250-foot shoreland district around great ponds, rivers, freshwater wetlands, and tidal waters — which covers the Atlantic coastline, Casco Bay islands, Sebago Lake, and the Presumpscot corridor — with a standard 75-foot setback for new structures and limits on impervious surface and vegetation removal that can restrict where a stored RV or boat trailer pad may be placed. Check the specific municipality's zoning ordinance (typically the residential-district 'accessory uses,' 'storage of recreational vehicles,' or 'commercial vehicles' section) and any shoreland overlay for setback rules before parking long-term.
