What a valid Connecticut rent increase notice includes

  • • Full names of all tenants and the rental property address
  • • The landlord’s name and mailing address
  • • The current rent, the new rent, and the exact date the increase takes effect
  • • Service at least 45 days before the effective date (Conn. Gen. Stat. § 47a-4e)
  • • A certificate of service recording how and when the notice was delivered — courts routinely ask for this

NoticeKit generates all of the above, computes your actual notice period, and warns you — citing Conn. Gen. Stat. § 47a-4e — if your dates fall short of the Connecticut minimum.
