Does Maine cap how much lot rent can increase?

There is no flat dollar or percentage cap, but a 2025 law (10 M.R.S. §9093-B) created a market-based 'allowed lot rent increase' — the area average plus 1% above the Northeast Consumer Price Index — and the increase notice must disclose it. If the proposed increase is above that allowed amount, residents may request mediation.

Can residents challenge a large increase in Maine?

Yes, through mediation. Under §9093-B(3), if the proposed increase exceeds the allowed amount, owners 'representing 51% or more of the households in the community' may request mediation by certified mail within 90 days of the notice. The community owner pays the mediation costs, and bad faith can delay the increase for at least 6 months.

Mobile home lot rent rules in Maine

Q: How much advance notice does Maine require before a lot-rent increase?

At least 90 days. Under 10 M.R.S. §9093-B(1), an owner of a manufactured housing community 'shall provide notice of an increase in lot rent or fees no less than 90 days before the effective date of the increase to the owner of a manufactured home in the community.' This is general information, not advice about a specific increase — consider consulting a licensed attorney in Maine.

Maine has a dedicated mobile home park law — 10 M.R.S. Chapter 953, "Regulation of Mobile Home Parks; Landlord and Tenant" — and a 2025 amendment added detailed lot-rent-increase protections in §9093-B. The information below describes how the law generally works; anyone dealing with a specific increase should consider consulting a licensed attorney in Maine.

What the statute says

The controlling section for lot-rent increases is 10 M.R.S. §9093-B, "Manufactured housing community increase in lot rent and fees." On notice, subsection 1 provides:

An owner of a manufactured housing community shall provide notice of an increase in lot rent or fees no less than 90 days before the effective date of the increase to the owner of a manufactured home in the community.

That notice is not bare: subsection 2 requires it to state the owner's contact information, the dollar amount and type of the increase, the average lot rent and fees for a comparable community in the area, and "the average lot rent ... increased by 1% above the Consumer Price Index for the Northeast Region ... referred to in this section as 'the allowed lot rent increase.'" The notice must also explain the right to request mediation.

If the proposed increase is above the allowed amount, subsection 3 lets residents push back:

A number of owners representing 51% or more of the households in the community sign a written request for mediation

mailed by certified mail to the community owner within 90 days of the notice. Subsection 4 then requires the parties to select an independent mediator and meet, with "the owner of the manufactured housing community" paying all mediation costs; if the owner acts in bad faith, "the lot rent or fee increase may not take effect for at least 6 months."

How it works in general

A community owner who wants to raise lot rent gives each home owner at least 90 days' written notice that discloses the increase and how it compares to the statutory "allowed" amount (the local market average plus 1% above the Northeast CPI). The allowed amount is a benchmark, not a hard ceiling — an owner may propose more, but doing so triggers the residents' right to demand mediation if 51% of households sign on within the 90-day window. Mediation is paid for by the owner and aims to resolve the dispute; bad-faith conduct by the owner can postpone the increase for six months. General rule changes (other than rent or fees) require at least 30 days' written notice under §9093.

Common scenarios

General examples Maine park residents commonly encounter:

A rent-increase notice arrives. It must give at least 90 days and disclose the "allowed lot rent increase" so residents can see how the proposal compares.
The increase is well above the area average. If 51% of households sign a certified request within 90 days, the increase can be sent to mediation.
A park tries to change the rules. Rule changes (not rent) require at least 30 days' written notice under §9093.

Other authorities that may apply

Chapter 953 governs the tenancy, and §9093-B sets the increase process; the written rental agreement supplies any longer notice or additional terms. Rent and fee notice also ties to Title 14, section 6016 for residential estates. Local ordinances may add requirements, and federal law such as the Fair Housing Act can apply to how an increase is administered. A waiver of any right under Chapter 953 is unenforceable (§9097(7)).
