Connecticut Rent increase notice
How much notice does a landlord need to give to raise the rent in Connecticut?
A rent increase takes effect only if the landlord gives at least 45 days' written notice, or for leases of one month or less, notice equal to a full lease term. A tenant's silence is not agreement. This does not allow increases during a lease term. It applies to agreements entered, renewed or extended on or after Oct. 1, 2024.

Worked example for Connecticut
Example: A one-year lease is renewed on or after October 1, 2024, and you want a rent increase to take effect on August 1, 2026, when the new term begins. At least 45 days' written notice is due by June 17, 2026. The tenant's silence is not agreement. This rule does not allow an increase during a lease term. For a lease of one month or less, the notice is equal to a full lease term, not 45 days.
