What applies to your Connecticut tenancy?
Notice, timing and any cap depend on the kind of tenancy. The period on each card is Connecticut's minimum — your lease can require more, never less.

What a Connecticut rent increase notice must contain
✓Every adult tenant's name and the unit addressName each person on the lease so the notice binds all of them.
✓Current rent, new rent, and the differenceState both amounts and the increase as a dollar figure; a percentage on its own invites a dispute over the math.
✓An effective date that starts a rental periodAfter the full Per lease has run, on the first of a period — an increase mid-period is unenforceable in most states.C.G.S. § 47a-15a
✓Statement that all other lease terms continueUnless you are changing them too; then the notice is a change of terms and must list every change.
✓Notice date and delivery methodHand delivery or mail unless the lease agrees to electronic notices. Mailed notices add time in transit in most states.
✓Landlord signature and a copy on fileKeep the dated copy and the delivery record with the lease.auto-logged

2 · The renewal offer goes to the tenantDated, itemized and logged — that is the written notice. The tenant accepts on their phone.
3 · Rent and autopay update on the dateThe ledger, autopay and the lease record switch to the new amount on the effective date; nothing to re-enter.
Connecticut rent increase FAQ
How much notice does Connecticut require to raise rent?
Not set by statute — follow the lease (C.G.S. § 47a-15a). A fixed-term lease cannot be raised mid-term unless the lease says so.
Is there a limit on how much I can raise rent in Connecticut?
Fair rent commissions review increases (C.G.S. § 7-148b). See the Connecticut rent-control page for the current cap and which units are covered.
When does the increase take effect?
On the first day of a rental period after the notice period has fully run. Serve it a few days early so mail transit does not push it into the next month.
Can I raise rent by email?
Only if the lease agrees to electronic notices. The in-app renewal offer is emailed and logged; print it for hand delivery where the lease requires paper.
What if the tenant refuses?
On a month-to-month tenancy the tenant can give their own notice (Per lease in Connecticut) and leave; if they stay past the effective date, the new rent applies.
