Portland, ME Parking Rules: Commercial Vehicle Restrictions (2026)

Portland's Chapter 28 (Traffic and Motor Vehicles) does not impose a blanket overnight ban on commercial vehicles citywide, but several provisions tightly regulate where and how long commercial and oversized vehicles may park. Sec. 28-56(b) (Ord. No. 183-97, 1-22-97) governs truck-loading zones: 'No person shall stop, stand or park a commercial vehicle for any purpose or length of time other than for the expeditious unloading and delivery or pickup and loading of materials in any place marked as a truck loading zone during the hours from 6:00 a.m. to 6:00 p.m. Use of a truck loading zone shall be limited to vehicles with commercial or combination plates from any state and in no case shall the stop for loading or unloading of materials exceed thirty (30) minutes without a special street occupancy permit from the city.' Sec. 28-58(a) prohibits parking any motor vehicle exceeding 20 feet in length on any public street, public way, or publicly owned property in a residential-zoned area during November through March, with exceptions (Sec. 28-58(b)) for active deliveries, passenger pickup/discharge, utility/emergency/governmental service to abutting properties, and active street construction/repair. Sec. 28-57 forbids on-street parking for the principal purpose of (a) display for sale, (b) washing/greasing/repair (except emergency), (c) advertising, or (d) storage — with 'storage' defined as continuous parking in the same place for more than 10 consecutive days. The waiver-fee schedule kept under Sec. 28-51 includes 'Overtime Commercial Vehicle Zone' ($25.00) and 'No Parking / Dual Rear Wheels' fines. Chapter 28 does not adopt a separate definition of 'commercial vehicle' but defers under Sec. 28-1 to 29-A MRS § 101 (which uses registration plate classification). Maine state law 29-A MRS § 2068 establishes baseline parking rules statewide; Portland's home-rule ordinance imposes the more restrictive layered limits described above.
