Grace period, late fee cap, and pay-or-quit notice rules — C.G.S. § 47a-15a
Under C.G.S. § 47a-15a, Connecticut gives tenants a 9-day grace period after rent is due. During this window, a landlord may not charge a late fee or serve a pay-or-quit notice. The grace period begins on the rent due date stated in the lease. Only after the grace period expires may the landlord impose a late charge and begin the eviction notice process.
9-day grace period from the due date. After day 9, landlord may charge $5/day in late fees and serve a 3-day notice.
Connecticut caps late fees at $5/day after grace expires under C.G.S. § 47a-15a(b). Any late fee above this statutory maximum is unenforceable, even if the tenant agreed to it in the lease. At the statewide median rent of $1,707/month, a 5% fee would equal approximately $85 — verify the exact percentage allowed under your state's statute.
Once rent is late and the 9-day grace period has expired, the landlord must serve a formal 3-day pay-or-quit notice (C.G.S. § 47a-23) before filing for eviction. This notice must state the total amount owed and give the tenant the option to either pay in full or vacate. If the tenant does neither, the landlord may file an unlawful detainer action in Connecticut court.

However, landlords must first wait out the 9-day grace period, then serve a 3-day pay-or-quit notice and wait for it to expire before filing. Most landlords prefer to work with tenants before filing, as eviction court costs and lost vacancy time often exceed one month's rent.
