Connecticut enforces specific statutory regulations regarding when and how much a residential landlord can charge for late rent. The state mandates specific grace periods that cannot be waived in a lease agreement, and laws implemented in 2023 establish strict limitations on the late fees landlords may charge.

Failing to adhere to the statutory grace period before issuing a Notice to Quit or charging an unauthorized late fee can lead to legal complications or the dismissal of an eviction case.

The Mandatory Statutory Grace Period

Connecticut law (C.G.S. § 47a-15a) establishes a mandatory grace period during which a landlord is prohibited from charging late fees or initiating eviction proceedings for nonpayment.

• Monthly Leases: The law mandates a nine (9) day grace period. While rent is typically due on the 1st, a tenant is protected from late fees and termination for nonpayment until the expiration of the 9th day.
• Weekly Leases: For tenants who pay rent on a week-to-week basis, the statutory grace period is four (4) days.

A landlord cannot charge a late fee, nor can they legally issue a 3-Day Notice to Quit for nonpayment, during these grace periods. Any lease provision attempting to establish a shorter grace period is void and unenforceable.

Caps on Late Fee Amounts

Under C.G.S. § 47a-15a(b), Connecticut significantly limits the amount a landlord can charge once the statutory grace period has expired. Late fees must be clearly outlined in a written lease agreement to be enforceable.

A Connecticut residential landlord may only charge a late fee equal to the lesser of the following two amounts:

1. $5.00 per day for each day the rent is late, up to a maximum cap of $50.00 per month.
2. 5% of the delinquent rent payment. (If the tenant receives a rental assistance subsidy, such as Section 8, the late fee cannot exceed 5% of the tenant's specific out-of-pocket rent portion).

Maximum Fee allowed: $45. | | Rent is $2,000/mo. Tenant pays 14 days late. | 5% of 2,000 = $100.
$5/day for 14 days = $70 (Capped at $50).

Maximum Fee allowed: $50. |

Regardless of the scenario, a Connecticut landlord is legally prohibited from assessing more than one late fee for a single delinquent monthly rent payment. A landlord cannot continuously stack consecutive late fees on top of a single missed payment month after month.

Serving a Notice to Quit

Once the statutory grace period expires—meaning the rent has not been received by the end of the 9th day (for monthly leases)—the landlord may initiate the eviction process.

The first step is serving the tenant with a 3-Day Notice to Quit Possession. It is standard practice to base this notice strictly on the unpaid rent amount. While late fees are legally owed under a valid lease, relying solely on unpaid late fees as the primary basis for an eviction for nonpayment can be legally precarious. Landlords often choose to recover unpaid late fees through security deposit deductions at the end of the tenancy, as permitted by C.G.S. § 47a-21.
