Portland, ME Parking Rules: Commercial & Oversized Vehicles (2026)

Section 28-58, "Parking of trucks and certain other vehicles prohibited," sets a seasonal length limit for residential streets. Subsection (a) prohibits stopping, standing, or parking "any motor vehicle which exceeds twenty (20) feet in length in any area zoned residential pursuant to the zoning ordinance on any public street, public way, or publicly owned property, during the months of November through March": the same window the city uses for its overnight snow-related parking restrictions. Subsection (b) exempts vehicles that are actually working: those making deliveries, picking up or dropping off passengers, loading or unloading cargo, or providing governmental, utility, emergency, or other services to abutting properties, plus vehicles engaged in the construction, repair, or maintenance of public streets and ways.

A related limit in the same section, subsection (c), caps how long recreational vehicles can sit on any street: no boat, camper, trailer, RV, or snowmobile may be parked on a street for more than 24 cumulative hours in any seven-calendar-day period, and that limit runs year-round, not just November through March. The city's posted parking fine schedule under Section 28-51 lists "Parking a Vehicle 20' or more in Residential Area November-March" and the camper/trailer/boat overstay as separate citable violations, each enforced by the Parking Division's parking control officers alongside the Traffic and Motor Vehicles chapter's general stopping-and-standing rules.
