Small landlord exemptions from just-cause eviction and rent control laws
Yes — Maine draws a real line for small landlords, but only if you live in the building. Since 2023, 14 MRS §6001-A (enacted as LD 1475) has required just cause before a Maine landlord can refuse to renew a tenancy that has lasted at least one year. The statute carves out one group: under 14 MRS §6001-A(1)(A), owner-occupied buildings with 3 or fewer units are exempt from the just-cause requirement entirely.
That makes Maine a partial-exempt state — the carve-out turns on where you sleep, not how many doors you own. An investor with a single off-site duplex gets no exemption; an owner-occupant of a triplex gets the full one. Portland layers on local rent control with its own, tighter owner-occupied exemption (2 units or fewer), and Rockland regulates rents locally too. The rest of this page maps exactly where those lines fall.
The term "mom-and-pop landlord" typically refers to an individual or family that owns a small number of residential rental units, often 1 to 4, and frequently lives in or near the property. In states with tenant-protection legislation, the legislature has carved out exemptions recognizing that small landlords operate differently from large institutional property managers.
Because Maine has active just-cause or rent-control legislation, small landlords must understand whether they qualify for an exemption, and structure their ownership accordingly to preserve that protection.
The exemption in 14 MRS §6001-A(1)(A) has two conditions, and both must be true: the building has 3 or fewer units, and you occupy one of them as the owner. Meet both and the just-cause requirement simply does not apply to you — you can decline to renew a lease after a year for your own reasons, the way every Maine landlord could before 2023.
What the exemption is not: a portfolio-size rule. Maine did not exempt "landlords with fewer than X units." A retiree who owns one duplex across town and lives elsewhere is fully covered by just-cause. A house-hacker renting out two units of the triplex they live in is fully exempt. If you own several small buildings, the exemption is evaluated building by building — only the one you actually live in qualifies.
LD 1475 made just-cause nonrenewal a statewide rule after one year of tenancy, but rent regulation in Maine remains purely local: only Portland and Rockland have ordinances. Portland's rent control exempts owner-occupied buildings with 2 or fewer units — a tighter cutoff than the state's 3-unit just-cause exemption.
That mismatch is the trap worth memorizing. An owner-occupied Portland triplex is exempt from state just-cause but still subject to Portland rent control. Live in a Portland two-family and you clear both. Everywhere else in Maine, no rent cap applies at all — the market, where average rent runs about $1,028, is the only ceiling. If you own in Rockland, read that city's ordinance directly; its terms are its own, and this page's Portland thresholds do not transfer.
Owner-occupancy buys you out of just-cause. It buys you out of nothing else. Four obligations apply to a Maine landlord with one unit exactly as they apply to one with a thousand:
First, classify each building honestly: do you live in it, and does it have 3 or fewer units? Only a yes to both puts you outside 14 MRS §6001-A. A 4-unit building fails the test even if you live there.
Second, if you are exempt, still paper every nonrenewal — dated notice, a file note of your business reason. Exemption status can be challenged, and a clean record ends the argument early.
Third, never skip the courthouse. Every Maine eviction, exempt or not, runs through the Forcible Entry and Detainer process under 14 M.R.S. § 6001 et seq. — changing locks or cutting heat converts a routine case into liability.
Fourth, Portland and Rockland owners: confirm your local rent-regulation status before quoting a renewal number, because the city thresholds are not the state's.
This page was researched and written by the Eviction Risk Map research team based on 14 MRS §6001-A (Maine's just-cause nonrenewal law enacted by LD 1475 in 2023), 14 M.R.S. § 6001 et seq. (Forcible Entry and Detainer), 14 M.R.S. § 6021 (warranty of habitability), and the local rent control ordinances of Portland and Rockland. Last reviewed July 2026. This is general information for small landlords, not legal advice — confirm how these rules apply to your specific building with a Maine landlord-tenant attorney before acting on a nonrenewal or rent increase.
Only if you live in the building. Maine's LD 1475 (2023), codified at 14 MRS §6001-A, requires just cause to non-renew a tenant after one year of tenancy — but owner-occupied buildings with 3 or fewer units are exempt under §6001-A(1)(A). A duplex or triplex you live in qualifies. A duplex you own but rent out entirely does not, no matter how small your portfolio is. The exemption follows the building and your residence in it, not your unit count as an owner.
In most of the state, yes — Maine has no statewide rent cap, and with average rent around $1,028 the market sets the ceiling. The exceptions are local: Portland and Rockland have their own rent regulation ordinances. Portland's rent control exempts owner-occupied buildings with 2 or fewer units — note that is a tighter threshold than the state's 3-unit just-cause carve-out, so an owner-occupied Portland triplex escapes just-cause but not rent control. Outside those two cities, no cap applies.
Four never scale away: the warranty of habitability under 14 M.R.S. § 6021, the anti-retaliation protections tied to 14 M.R.S. § 6001, the requirement to give 24 hours' notice before entering a tenant's unit, and fair housing law. You must also use the formal Forcible Entry and Detainer court process (14 M.R.S. § 6001 et seq.) for any eviction — self-help lockouts are off the table even for an owner-occupant with a single rental unit.
It is the hinge for both major carve-outs. Statewide, living in your ≤3-unit building exempts you from 14 MRS §6001-A's just-cause nonrenewal rule. In Portland, living in a ≤2-unit building exempts you from local rent control. But if you move out — even keeping the same building — both exemptions can fall away, because each is conditioned on the owner actually occupying the property. Owner-occupancy does not change your habitability, retaliation, entry-notice, or fair housing obligations at all.
