Connecticut compliance obligations
Connecticut landlords commonly track 5 state and local compliance obligations, each listed below with its schedule, its sources, and the date we last verified it. Among them: file Connecticut LLC annual report by March 31, pay annual security deposit interest on tenancy anniversary, and pay first property tax installment, usually due July 1.
File Connecticut LLC annual report by March 31
If the property is held in an LLC formed in or registered with Connecticut, file the LLC's $80 annual report online with the Secretary of the State by March 31, because an overdue report blocks a certificate of legal existence and can lead to dissolution by forfeiture.

Pay annual security deposit interest on tenancy anniversary
Connecticut requires landlords to pay or credit interest on security deposits on each anniversary of the tenancy, at a rate tied to the state deposit index.

Pay first property tax installment, usually due July 1
Connecticut towns set their own property tax installments, typically with the first real estate installment due July 1 and a second on January 1 (some towns bill quarterly), and an installment unpaid by August 1 is charged interest of 1.5 percent a month back to the July 1 due date.

Return security deposit with itemized statement within 21 days of move-out
Connecticut landlords must deliver the full security deposit plus accrued interest, or the balance plus interest with a written statement itemizing each deduction, within 21 days after the tenancy ends or 15 days after receiving the tenant's written forwarding address, whichever is later, and missing the deadline can make the landlord liable for twice the full deposit, so send it by certified mail with a return receipt to prove timely delivery.

Verify smoke and CO alarms in all units
Connecticut fire and building codes require working smoke alarms in every rental unit and carbon monoxide alarms where the codes call for them, typically in units with fuel-burning appliances, a fireplace, or an attached garage, so an annual documented check that replaces weak batteries and any alarm past its replacement date keeps units safe and compliant.

Seasonal maintenance for Connecticut
Landlords in Connecticut plan upkeep around a cold climate: this guide lists 7 seasonal maintenance items for Connecticut in calendar order, each with its timing and the date we last verified it. Among them: check ice dams and roof snow load after major storms, smoke and CO detector seasonal test, and spring thaw inspection: roof and foundation.
Check ice dams and roof snow load after major storms
Connecticut's freeze-thaw winters and heavy nor'easter snow, deepest in January and February, build ice dams and heavy roof loads, so a midwinter check from the ground, repeated after big storms, catches backed-up meltwater and overloaded roofs before ceilings and walls are damaged.

Smoke and CO detector seasonal test
An annual full test of smoke and CO detectors (beyond battery swaps) confirms every alarm actually sounds.

Spring thaw inspection: roof and foundation
Freeze-thaw cycles crack roofs and foundations; a spring inspection catches winter damage early.

Complete a storm readiness check before peak hurricane season
Tropical storms can bring damaging wind, falling trees, and flooding well inland in Connecticut and storm surge along the Long Island Sound shoreline, so checking the roof, nearby trees, gutters, and drainage and reviewing insurance by early July leaves time for a new federal flood insurance policy, which takes 30 days to start, to be in force before the mid-August to mid-October peak.
