21 days after the tenancy ends

A security deposit generally may not exceed two months’ rent, or one month if the tenant is 62 or older (Conn. Gen. Stat. § 47a-21). Interest is due at the banking commissioner’s rate. Unused deposit is generally due within 21 days after the tenancy ends.

Notices and entry

A month-to-month tenancy generally takes notice equal to one rental period. A notice to quit is a separate eviction step (Conn. Gen. Stat. § 47a-23).

The landlord may enter at reasonable times. Except in an emergency, give reasonable notice; 24 hours is the usual writing (Conn. Gen. Stat. § 47a-16).

A Connecticut rent increase should be in writing. Many landlords use at least the same notice they would use to end a month-to-month tenancy. A month-to-month tenancy generally takes notice equal to one rental period. A notice to quit is a separate eviction step (Conn. Gen. Stat. § 47a-23). The lease may require more. Local rent-control rules can cap the amount even when the notice period is met.

Eviction notices

Connecticut eviction starts with a notice to quit. Many grounds need a cure notice first. Do not use this in place of the official notice-to-quit form if a court expects that form.

  • Connecticut uses a notice to quit, generally at least 3 days (Conn. Gen. Stat. § 47a-23), not a separate pay-or-quit cure in every case.
  • Pay-or-quit deadline: 3 days
  • A notice to quit must be served like a summary-process paper. Consider a process server.
