Connecticut’s October 1 Rental Laws: No Utility Billing Without a Meter, Up to $100,000 Deposit Penalties, New Rules for Your Manager
Several new Connecticut laws take effect on October 1, 2026. The General Assembly’s research office summarized them in its 2026 Acts Affecting Housing and Real Estate report. Four matter most to an owner who lives elsewhere and relies on a manager. Here is what the public acts themselves say.
The facts: what changes
1. No utility billing without a separate meter. Public Act 26-113 adds an eleventh item to the list of lease terms banned by Conn. Gen. Stat. § 47a-4. A rental agreement may not provide that the tenant “agrees to pay for utilities billed to the tenant if no separate meter is used to measure utilities delivered exclusively to such tenant’s dwelling unit.” The act applies to rental agreements entered into or renewed on or after October 1, 2026.
It builds on Section 16-262e(c), which already makes the owner, agent or manager liable for electricity, gas, water or heating fuel supplied to a building, except service that is individually metered or billed for one unit’s exclusive use. The bill analysis also cites the 2024 Connecticut Supreme Court decision in Northland Investment Corp. v. PURA, 349 Conn. 35. A master-metered landlord could not bill tenants variable, landlord-allocated utility charges, but could estimate costs and “build in” that figure to the rent.
2. Security deposit violations can now draw a civil penalty of up to $100,000. Public Act 26-79, § 3 amends § 47a-21(j). The Banking Commissioner, who could already order a landlord to stop and comply, may now also order a civil penalty. The bill analysis puts the cap at $100,000, the commissioner’s general penalty limit. The commissioner’s jurisdiction covers four subsections of § 47a-21:
- (b) the deposit cap: two months’ rent, or one month for a tenant aged 62 or older;
- (d) the return deadline: 21 days after the tenancy ends, or 15 days after receiving the tenant’s forwarding address, whichever is later;
- (h) holding the full deposit in an escrow account “immediately”;
- (i) interest on deposits.
Two limits remain. The commissioner has no jurisdiction over a failure to pay annual interest. The commissioner also has none over deposits withheld because of a good-faith damage claim, even if the tenant disputes the amount. Private remedies remain: twice the deposit for a late return, twice the accrued interest (at least $10) for unpaid interest.
3. Your manager and screening vendor are bound by the fee rules. Public Act 26-68, § 59 (the budget act) rewrote § 47a-4d and took effect when it was signed on May 26, 2026. The ban on application-processing fees and the rules on screening reports now apply to “a third party acting on behalf of a landlord,” not only to the landlord. The only charges allowed before or at the start of a tenancy are a security deposit, the first month’s rent in advance, a key or special-equipment deposit, and a screening-report fee of up to $50 plus the housing commissioner’s annual CPI adjustment. Move-in and move-out fees are banned, and a screening fee requires giving the applicant the report (or how to request it) and the vendor’s receipt.
4. Listing agents must market 1-4 unit rentals publicly unless you opt out in writing. Public Act 26-23, § 32 covers brokers and agents who represent a landlord or seller of a one- to four-unit property, including a condo unit. Agents must treat prospective tenants on an “equal and nondiscriminatory basis” and put the unit on a publicly accessible platform (an MLS or open website) no later than its first “public marketing.” A landlord who wants a private listing signs a statutory Landlord Opt-Out of Real Estate Public Marketing form when the listing agreement is signed. Licensees who violate the rules face fines of up to $5,000 per violation (bill analysis).
What did not pass: SB 257, which would have expanded Connecticut’s for-cause eviction protections. Its status page shows committee approvals but no public act. Also note an existing rule many remote owners miss: under § 47a-21(f), a landlord who does not live in Connecticut must appoint the Secretary of the State in writing as its agent for service of process.
Interpretation, not fact: what this means for a remote owner
The common misconception is that a utility split is fine as long as the tenant signs a lease agreeing to it. For leases signed or renewed from October 1, that term is unenforceable if the unit has no separate meter measuring its own use. That hits older two- to four-family buildings with one water meter or one boiler, common in Connecticut.
Two questions are not settled by the text. First, the act says “separate meter,” not “utility-company meter.” Whether a landlord-installed submeter qualifies is an open question for a Connecticut attorney. The ratio billing that Northland rejected clearly does not. Second, month-to-month tenancies arguably “renew” each period. A cautious owner would treat them as covered from October 1. The approach the court described, estimating annual costs and pricing them into a flat rent, is the lower-risk route. Re-underwrite before your next renewal.
On deposits, the practical change is who can come after you. A Banking Department complaint can now end in a fine, not just an order to comply. The remote-owner exposure is the manager’s escrow setup and missed 21-day deadlines.
Checklist before your next Connecticut renewal
- List every unit without its own utility meter, and flag any lease that bills the tenant for a share of a utility.
- For leases starting or renewing on or after October 1, remove the utility charge or move to a flat, all-in rent. Get Connecticut counsel on any submeter setup.
- Ask your manager in writing where deposits are escrowed, how interest is calculated, and how the 21-day/15-day return clock is tracked.
- Check your manager’s and screening vendor’s application fees against § 47a-4d, including any “admin” or “processing” fee.
- If you list through a broker, decide on public versus private marketing before signing, and keep any opt-out form.
- Confirm your written appointment of the Secretary of the State is on file.
