Statute

Conn. Gen. Stat. § 47a-15a(b)

Connecticut limits residential late fees under Conn. Gen. Stat. § 47a-15a(b): the fee may not exceed the lesser of $5 per day (up to $50 total) or 5% of the delinquent rent payment. A lease can agree to less, but a fee above the statutory limit is generally unenforceable.

Timing matters as much as the amount: rent must be at least 9 days past due before a late fee can be assessed. A fee charged inside that window isn't collectible in Connecticut, even when the lease provides for it.

Connecticut allows only one late charge per delinquent payment no matter how long it stays unpaid. The nine-day grace period applies to month-to-month and longer tenancies (week-to-week tenancies get four days), and for subsidized tenancies the 5% is measured against the tenant's share of rent only.
