✓ Law Verified September 2026
Connecticut late fee laws decide two things every renter eventually needs to know: how many days you have before a late fee can be charged, and how big that fee is allowed to be. This guide gives the Connecticut answer to both in plain English, plus what to do when a fee breaks the rules, verified against official Connecticut sources as of September 2026.
In This Connecticut Guide:
Connecticut Late Fee Laws at a Glance
| Grace period before a late fee | 9 days after rent is due for monthly tenancies (4 days for week-to-week tenancies). No late fee can be charged during this grace period (Conn. Gen. Stat. 47a-15a). |
| Cap on the late fee | The lesser of 5 per day up to a maximum of 50, or 5 percent of the late rent payment. If a government or charitable program pays part of the rent, the cap is 5 percent of the tenant’s share only (Conn. Gen. Stat. 47a-15a, as amended by Public Act 23-207, effective October 1, 2023). |
| Must be in the written lease | YES. The landlord can charge a late fee only if the tenant signed a valid written agreement to pay one, as required by 47a-15a and 47a-4(a). Without a written late-fee clause, many tenants can refuse to pay the fee. |
| Per-day late fees | YES, with limits. A per-day fee is allowed only up to 5 per day, capped at 50 total or 5 percent of the late rent, whichever is less. The landlord may charge only ONE late charge per late rent payment, no matter how long the rent stays unpaid. |
How Much A Connecticut Landlord Can Charge
The cap: The lesser of 5 per day up to a maximum of 50, or 5 percent of the late rent payment. If a government or charitable program pays part of the rent, the cap is 5 percent of the tenant’s share only (Conn. Gen. Stat. 47a-15a, as amended by Public Act 23-207, effective October 1, 2023).
Connecticut has a statutory cap, so courts measure a late fee against the limits in 47a-15a and 47a-4 rather than a general reasonableness test. A lease clause charging more than the cap, or charging during the grace period, is barred by Conn. Gen. Stat. 47a-4(a) and cannot be enforced against the tenant.
Under the Connecticut late fee laws, the number in the lease is the starting point, not the last word. A fee that is legal in size can still be illegal in timing (charged before the grace period runs), in form (never written into the lease), or in how it is collected.
The Grace Period: When the Clock Actually Starts
Statutory grace period in Connecticut: 9 days after rent is due for monthly tenancies (4 days for week-to-week tenancies). No late fee can be charged during this grace period (Conn. Gen. Stat. 47a-15a).
A lease can give you more time than the Connecticut late fee laws require, but never less. A fee charged inside the grace period is not owed.
Three Rules Landlords Get Wrong
Must the fee be in the lease? YES. The landlord can charge a late fee only if the tenant signed a valid written agreement to pay one, as required by 47a-15a and 47a-4(a). Without a written late-fee clause, many tenants can refuse to pay the fee.
Can it come out of your deposit? UNVERIFIED. Conn. Gen. Stat. 47a-21 lets a landlord deduct unpaid rent and damages caused by the tenant’s failure to meet lease obligations, but no statute or court ruling found says late fees specifically may be deducted. An illegal late fee (above the cap or charged during the grace period) should not be deductible. Check with CTLawHelp or your court.
Can a late fee alone get you evicted? Connecticut’s nonpayment eviction (summary process under 47a-23) is based on unpaid RENT. After the 9-day grace period, the landlord may serve a Notice to Quit for unpaid rent. The statute does not say whether late fees alone can support an eviction (UNVERIFIED). Many tenants can argue that late charges are not rent. Check with your housing court or legal aid.
What to Do About an Illegal Late Fee in Connecticut
Lease clauses that break 47a-4 or 47a-15a cannot be enforced, so you may be able to refuse to pay the illegal part of the fee. You can dispute the fee in writing, raise it as a defense in housing court, or sue to recover overcharges in Connecticut small claims court.
You may also be able to file a complaint with your town’s fair rent commission or with the Attorney General’s consumer assistance unit.
The statute found sets no specific penalty the landlord must pay for an illegal late fee (UNVERIFIED).
Whatever the remedy, keep paying the rent itself on time and in full. Dispute the fee separately, in writing, citing the Connecticut late fee laws rule it breaks, and keep a copy. Landlords rarely file a case over a disputed fee; they do file over unpaid rent, so never withhold rent to protest a fee.

Do the Math Before You Pay
Take the fee in your lease and compare it to the rent. A fee of a few percent of monthly rent is the range most Connecticut courts accept as reasonable; a fee that approaches a week of rent, or one that keeps growing by the day without limit, is the kind that gets thrown out.
Then check the date: count the days from the due date to the day the fee was charged, and set that against the grace period above.
Two numbers decide almost every late-fee dispute, the size of the fee and the day it was charged. Write both down before you call the landlord, because the Connecticut late fee laws are easiest to enforce when you can state exactly which rule was broken.
Paper Beats Memory: Protecting Yourself Going Forward
Pay rent in a way that leaves a dated record, a bank transfer, a portal receipt, a check image, so a “late” claim can be answered with a timestamp. If you know rent will be late, tell the landlord in writing before the due date; many will waive the fee once, and the message itself is evidence of good faith.
Keep every fee notice. A pattern of fees charged inside the grace period, or above the cap where Connecticut has one, is exactly the evidence a small-claims judge wants to see, and it is the evidence that turns one disputed fee into a refund of every fee you paid.
Recent changes in Connecticut: Public Act 23-207 (effective October 1, 2023) cut the late-fee cap to the lesser of 5 per day up to 50, or 5 percent of the late rent. It also limits landlords to one late charge per late payment and protects subsidized tenants by basing the fee only on their share of the rent. No 2024-2026 change to the late-fee cap was verified.
