How Connecticut Late Fees Work

Connecticut regulates late fees under § 47a-15a with a structure unlike most other states: a daily accrual system subject to a dual cap. After a 9-day grace period, the landlord may charge $5 per day for each day the rent remains unpaid, up to a maximum of $50 in daily accruals. However, the total fee is then compared against 5% of the delinquent rent, and the tenant pays whichever amount is less.

The 9-day grace period is one of the longest among the states we cover and provides substantial breathing room. It means that if your rent is due on the 1st, no late fee can accrue until the 10th. Rent paid at any point during the first 9 days is considered timely. Once the grace period expires, the $5/day clock starts — but only for days beyond the 9th day, not retroactively from the due date.

Connecticut also prohibits fee pyramiding: your landlord cannot carry forward unpaid late fees and charge additional penalties on top of them. The combination of the generous grace period, the daily accrual structure capped at $50, and the 5% comparison makes Connecticut one of the most tenant-protective states for late fee regulation. If you are overcharged, you have the right to recover the excess amount.

Example: CT Late Fee Calculation

Your monthly rent is $800 and you pay 16 days after the due date.

→ Grace period check: 16 days late > 9-day grace period → fee applies

→ Days past grace: 16 − 9 = 7 days of accrual

→ Daily accrual: 7 days × $5/day = $35 (under the $50 daily cap)

→ Compare to 5% of rent: $800 × 0.05 = $40

→ Fee is the lesser of the two: $35 (accrual) vs. $40 (5%) → $35

Your late fee is $35. Even though 5% of $800 would allow up to $40, the daily accrual only reached $35 over 7 days past grace, and Connecticut requires the lesser amount. Note: if you had paid on day 6 (within the 9-day grace period), the fee would have been $0.

Frequently Asked Questions

How long is the grace period for late rent in Connecticut? ▼

Connecticut provides a 9-day grace period under § 47a-15a — one of the longest in the country. No late fee can be charged until the 10th day after rent is due. If rent is due on the 1st, you have until the 9th to pay without any penalty. If your landlord charges a late fee before the 9-day grace period expires, that charge is illegal and you can recover the overcharge.

What is the maximum late fee in Connecticut? ▼

The maximum is the lesser of two calculations: (1) $5 per day for each day past the 9-day grace period, capped at $50 in daily accruals, or (2) 5% of the delinquent rent. You pay whichever is lower. For example, on $800 rent paid 16 days late: the daily accrual is $35 (7 days × $5) and 5% of rent is $40 — so the fee is $35. The absolute maximum possible under any scenario is $50.

Can late fees compound or pyramid in Connecticut? ▼

No. Connecticut prohibits fee pyramiding under § 47a-15a. Your landlord cannot add unpaid late fees from prior months to your current rent balance and then charge additional late fees on the combined total. Each month's late fee is calculated independently based solely on that month's delinquent rent.

How does the daily accrual work for Connecticut late fees? ▼

After the 9-day grace period expires, the late fee accrues at $5 per day for each additional day the rent remains unpaid, up to a maximum of $50 in daily accruals. Importantly, accrual does not start from the due date — it starts from day 10. So if rent is due on the 1st and you pay on the 16th, that is 7 days past the grace period: 7 × $5 = $35. The daily accrual total is then compared to 5% of the rent, and you owe the lesser amount.
