Portland, ME Short-Term Rentals: Parking Rules (2026)

Portland Code of Ordinances Chapter 6, Article VI (§§ 6-150 et seq., STR registration) does not impose an STR-specific off-street parking mandate. Parking compliance is governed by (a) the off-street parking ratio for the unit's underlying zoning district in the Land Use Code (Chapter 14), which is generally one space per dwelling unit in most residential zones but is reduced or waived in the downtown / B-zones and in the India Street, Bayside, and other zero-minimum areas adopted as part of Portland's parking-minimum reforms, and (b) any condominium- or HOA-assigned parking. On the state side, the LD 2003 ADU statute (30-A MRS § 4364-A) caps additional ADU parking demand at one space per ADU. On-street parking is governed by Portland Code Chapter 28 (Traffic and Parking), including overnight winter parking bans (typically November 1–April 15, posted by the Department of Public Works), residential permit-parking zones, and standard alternate-side rules. STR operators are responsible for clearly disclosing to guests which spaces are available, the on-street rules, and any winter ban that may apply during the stay.
