Connecticut Mobile Home Park Rent Control: 2026 Guide

Is mobile home lot rent controlled in Connecticut?

Yes and no. Connecticut does not impose a statewide cap or a fixed percentage limit on how much you can raise mobile manufactured home lot rent. But 'no cap' is not 'no rules.' Two layers of control apply: the notice and minimum-term rules in Chapter 412 (the Mobile Manufactured Homes act), and case-by-case review by a municipal fair rent commission that can strike down an increase it finds 'harsh and unconscionable.'

For operators, that means the number is not fixed by statute, but both how and how often you raise rent are regulated, and any increase you set can be challenged as excessive before a local commission. The practical takeaway: set increases you can defend with comparable-lot data, give proper written notice, and time changes to the lease cycle.

Connecticut has no statewide rent cap

There is no statewide rent-control statute in Connecticut and no numeric ceiling on annual rent increases. The state has never adopted a percentage cap for mobile home lot rent or for apartments.

The control mechanism is different. Instead of a hard cap, Connecticut relies on (1) mandatory notice and minimum-term rules for mobile home parks, and (2) a 'harsh and unconscionable' fairness review by local fair rent commissions under C.G.S. §7-148b to §7-148f. So your effective ceiling is 'what a commission would consider fair and equitable,' not a set number.

Mobile home park notice and term rules (Chapter 412)

Connecticut fixes the lease cycle before it touches the rent number. C.G.S. §21-70(b) provides that 'the term of each rental agreement and renewal shall not be less than one year unless the resident requests, in writing, a term for less than one year.' In practice that means lot rent generally changes only once a year, at renewal, and never mid-term.

When the agreement terminates, C.G.S. §21-80(b)(5) lets you raise the rent only if you (A) deliver written notice of the proposed increase at least thirty days before the start of the new rental agreement, (B) keep the new rent 'consistent with rents for comparable lots in the same park,' and (C) do not raise it 'in order to defeat the purpose' of the statute. Send the notice in writing, at least 30 days out, and keep your comparable-lot documentation on file.

Fair rent commissions can review your lot rent

Mobile home park lots are squarely within fair rent commission jurisdiction. C.G.S. §7-148b(a) states that a commission's authority over 'housing accommodations ... shall include mobile manufactured homes and mobile manufactured home park lots' (seasonal rentals excluded). Your residents can take a lot-rent increase to the town's commission for review.

Since Public Act 22-30, this is not a niche concern: §7-148b(b) requires every town, city or borough with a population of 25,000 or more to have adopted an ordinance creating a fair rent commission by July 1, 2023 — so most parks in mid-size and larger Connecticut towns now sit in a jurisdiction with an active commission.

The standard is that a commission may reduce a rent or proposed increase it finds 'so excessive ... as to be harsh and unconscionable' (§7-148d(a)), weighing the factors listed in §7-148c. And under the anti-retaliation rule in §21-80a, you cannot demand a rent increase within six months after a resident files a fair rent complaint or asserts protected rights.

Rent-increase rules at a glance in Connecticut

• No statewide cap
  Connecticut sets no percentage limit on lot-rent increases — there is no rent-control statute and no numeric ceiling.
• One-year minimum term
  C.G.S. §21-70(b): each rental agreement and renewal must be at least one year unless the resident asks in writing for less, so rent typically changes once a year.
• 30-day written notice
  C.G.S. §21-80(b)(5): deliver written notice of the increase at least thirty days before the new rental agreement starts.
• Comparable-lot standard
  The new rent must be 'consistent with rents for comparable lots in the same park' and must not be raised to defeat the statute's purpose (§21-80(b)(5)).
• No mid-term increases
  Rent may be raised only at the termination/renewal of the agreement, never during the term.
• Fair rent commission review
  C.G.S. §7-148b(a): commission jurisdiction expressly includes mobile manufactured home park lots, so residents can challenge an increase as excessive.
• Mandatory commissions in larger towns
  P.A. 22-30 (§7-148b(b)): every town of 25,000+ had to create a fair rent commission by July 1, 2023.
• 'Harsh and unconscionable' test
  §7-148d(a): a commission may reduce a rent or increase it finds 'so excessive ... as to be harsh and unconscionable,' using the factors in §7-148c.
• 6-month anti-retaliation window
  §21-80a bars demanding a rent increase within six months after a resident files a fair rent complaint or asserts protected rights.

Operator best practices in Connecticut

• Calendar increases to the one-year cycle
  Because §21-70(b) sets a one-year minimum term, plan lot-rent changes for renewal and never mid-term.
• Send written notice 30+ days out
  Meet §21-80(b)(5): put the new rent in writing and deliver it at least thirty days before the new term begins, and keep proof of delivery.
• Document comparable-lot data
  Maintain a rent roll and comps so you can show the increase is 'consistent with rents for comparable lots in the same park' if it is challenged.
• Check whether the town has a fair rent commission
  Any town of 25,000+ must have one (P.A. 22-30); confirm the local ordinance and its filing and hearing process before you raise rent.
• Be ready to defend 'not harsh and unconscionable'
  Tie increases to real cost drivers — taxes, utilities, capital improvements — that map to the §7-148c factors a commission weighs.
• Avoid anything that looks retaliatory
  Do not raise rent within six months of a resident's fair rent complaint or protected activity (§21-80a); it can be treated as illegal retaliation.
• Build a relationship with a Connecticut MHP attorney
  Chapter 412 and the fair rent commission process are technical and town-specific; a Connecticut mobile-home-park attorney can vet your notices, comps, and increase strategy before a dispute arises.
