Massachusetts Mobile Home Park Rent Control: 2026 Guide

Is mobile home lot rent controlled in Massachusetts?

Mostly no — but with real exceptions you cannot ignore. Massachusetts banned general residential rent control by statewide ballot in 1994 (Question 9), codified as the Massachusetts Rent Control Prohibition Act, M.G.L. c. 40P. That ban, however, expressly carved manufactured (mobile) home communities out of the definition of 'rent control,' so lot rent is not swept into the statewide prohibition the way apartment rents are.

In most of the state there is no percentage cap on how much you can raise lot rent, as long as you follow the notice and fairness rules. But roughly two dozen Massachusetts cities and towns still run local mobile-home-park rent control boards that survived the 1994 ban. If your community sits in one of those towns, that board — not you — controls your increases. The statewide guardrails are the Attorney General's unfair-practice regulations (940 CMR 10.00) and M.G.L. c. 140 §32L, plus whatever local ordinance applies.

The 1994 ban and the mobile-home carve-out

M.G.L. c. 40P §4 is blunt: 'No city or town may enact, maintain or enforce rent control of any kind,' unless the municipality formally accepts the chapter and meets strict conditions (voluntary, uncoerced compliance; compensating owners from municipal funds; applying only to owners of ten or more units). For apartments, this ended local rent control statewide.

The carve-out is in §3, which defines 'rent control' and then says the definition 'does not include the regulation of, or agreements affecting, publicly owned housing, publicly subsidized housing, federally assisted housing, or mobile homes.' Because mobile-home communities are outside the statutory definition of 'rent control,' the c. 40P ban never reached them. That is why municipalities retained the power to regulate mobile-home lot rent even though they lost it for conventional rentals — the carve-out, not a loophole, is what keeps local mobile-home rent control legal.

Notice and unfair-practice rules under c. 140 and 940 CMR 10.00

Even where no local board exists, you are not free to raise rent however and whenever you like. The Attorney General's regulations (940 CMR 10.00) and M.G.L. c. 140 §32L govern the process. Under 940 CMR 10.03, you must give each resident at least 30 days' written notice before a rent increase takes effect, and you cannot recover any charge that is not separately listed in the occupancy agreement. Under §32L(2), a rent increase that does not apply uniformly to a similar class of residents is presumptively unfair.

Community rule changes have a stricter path: §32L(5) requires you to send the revised rules by certified mail to the Attorney General and the Secretary of Housing and Livable Communities at least 60 days before the effective date, and to furnish them to residents at least 30 days before. All of this has teeth — §32L(7) makes any violation of c. 140 §§32A-32S an unfair or deceptive act under Chapter 93A, which exposes you to damages, multiple damages, attorney's fees, and Attorney General enforcement.

Local mobile-home-park rent control boards

This is the part operators most often get wrong. Despite the 1994 ban, about two dozen of Massachusetts's 351 municipalities still maintain mobile-home-park rent control boards or ordinances — including North Adams (which has a dedicated Chapter 26, 'Mobile Home Park Rent Control'), Chicopee, Pittsfield, Dalton, Palmer, Belchertown, and Ludlow, among others. In those communities, you generally cannot raise lot rent unless the local rent control board approves it.

State law defers to those ordinances rather than overriding them. Section 32L(7) states that 'if there is a rent control ordinance in existence such increase shall be subject to the provisions of said ordinance,' and 940 CMR 10.02 makes it an unfair or deceptive practice, where a community is under a rent control law, to 'impose any rent increase or additional fee, or to attempt to evict any tenant, except as permitted pursuant to such rent control law.' Always confirm your specific municipality before setting an increase.

Rent-increase rules at a glance in Massachusetts

• No statewide cap on routine increases
  Massachusetts sets no statewide percentage limit on ordinary lot-rent increases. The only statutory cap — CPI for Urban Consumers plus documented real-estate-tax/fee increases, not to exceed 10% — applies solely during a park closure (notice of discontinuance / change of use) period. (M.G.L. c. 140 §32L(7))
• Minimum notice: 30 days
  Give each resident at least 30 days' written notice before a rent increase takes effect. (940 CMR 10.03)
• Rule changes: 60 days to the state, 30 to residents
  Community rule changes must be sent to the Attorney General and Secretary of Housing and Livable Communities at least 60 days ahead and given to residents at least 30 days before they take effect. (M.G.L. c. 140 §32L(5))
• Increases must be uniform
  A rent change not applied uniformly to a similar class of residents creates a rebuttable presumption that it is unfair. (M.G.L. c. 140 §32L(2))
• Local ordinance controls if one exists
  If your community is in a town with a mobile-home-park rent control ordinance, that board governs increases regardless of the statewide default. (M.G.L. c. 140 §32L(7); 940 CMR 10.02)
• Park-closure cap: CPI + taxes, max 10%
  After you serve a notice of discontinuance or change of use, rent may rise only by CPI plus documented tax/fee increases (capped at 10%), no more than once per year, and only if the notice is given in good faith. (M.G.L. c. 140 §32L(7))
• Chapter 93A exposure
  Violating c. 140 §§32A-32S is an unfair or deceptive act under Chapter 93A, exposing you to damages, multiple damages, and Attorney General enforcement. (M.G.L. c. 140 §32L(7))

Operator best practices in Massachusetts

• Confirm whether your town has a rent control board first
  Before setting any increase, check your specific municipality — roughly two dozen towns still run mobile-home-park rent control boards, and in those you generally need board approval before raising lot rent.
• Always give at least 30 days' written notice
  Document the notice date and delivery for every resident so you can prove compliance with 940 CMR 10.03 if challenged.
• Apply increases uniformly
  Raise rent evenly across each similar class of residents; a non-uniform increase is presumptively unfair under §32L(2) and hard to defend.
• Put every charge in the occupancy agreement
  You cannot recover fees that are not separately listed in the agreement, and you cannot add entrance/exit fees or new mid-term charges for services previously included (940 CMR 10.03).
• File rule changes with the AG and Secretary
  Send any community-rule changes to the Attorney General and Secretary of Housing and Livable Communities 60 days ahead and to residents 30 days ahead, by certified mail, as §32L(5) requires.
• Handle park-closure increases with extra care
  During any discontinuance or change-of-use notice period, keep increases within CPI + documented taxes (max 10%), no more than annually, and in good faith — this is the one context with a hard statutory cap.
• Build a relationship with a Massachusetts MHP attorney
  The interplay of c. 40P, c. 140 §§32A-32S, 940 CMR 10.00, and local ordinances is genuinely tricky and Chapter 93A penalties are steep — have Massachusetts manufactured-housing counsel review your rules, notices, and any planned closure.
