Connecticut Crime-Free Housing Addendum

This Crime-Free Housing Addendum is built with Connecticut as the governing state. These are the Connecticut landlord-tenant rules that most often bear on it, with the statute for each.

Connecticut rules at a glance

Connecticut rules for a Crime-Free Housing Addendum
NonpaymentOnce the 9-day grace period passes, the landlord may serve a notice to quit giving at least three days before filing an eviction (§§47a-15a, 47a-23).
Lease violationsFor a curable material breach the landlord must first give written notice and 15 days to fix it; the right to cure doesn’t apply to a repeat within six months or to serious nuisance (§47a-15).
Notice to quit (month-to-month)At least 3 days before a summary-process (eviction) caseC.G.S. §47a-23

Ending a Connecticut tenancy

Connecticut doesn’t use the familiar “30 days to end a month-to-month” rule. A month-to-month tenancy ends by its own terms at the close of each rental period; what the statute regulates is the notice to quit that must precede an eviction case. The eviction itself runs through the summary-process court procedure — a landlord can never lock a tenant out.

Key Connecticut notice periods
Notice to quit (before summary process)At least 3 full days§47a-23
Nonpayment grace period9 days (4 days week-to-week)§47a-15a
Lease violation — right to cure15 days§47a-15
Rent increase45 days (or one full term for a lease of one month or less)§47a-4e
Family violence / sexual assault termination30 days, with documentation§47a-11e
  • Nonpayment — Once the 9-day grace period passes, the landlord may serve a notice to quit giving at least three days before filing an eviction (§§47a-15a, 47a-23).
  • Lease violations — For a curable material breach the landlord must first give written notice and 15 days to fix it; the right to cure doesn’t apply to a repeat within six months or to serious nuisance (§47a-15).
  • Protected tenants — In buildings with five or more units, tenants who are 62+ or have a qualifying disability can be evicted only for good cause — not simply because the lease ended (§47a-23c).
  • Survivors — A victim of family violence or sexual assault may end the lease on 30 days’ written notice with a sworn statement and a police, court or victim-services record; unpaid rent before termination is still owed (§47a-11e).
