Connecticut Rent Increase Rules During a Lease

If you’re renting a home or apartment in Connecticut, you might wonder what happens if your landlord tries to raise your rent before your lease ends. Understanding your rights can help protect you from sudden and unfair rent hikes. This article explains whether Connecticut landlords can legally raise your rent during a lease, and what steps renters can take if they face this situation.

Can a Landlord Raise Rent Mid-Lease in Connecticut?

In Connecticut, rental agreements are generally governed by the Connecticut General Statutes, Chapter 832: Landlord and Tenant Law.^[1]

• Fixed-term leases (e.g., 1-year lease): Landlords cannot raise the rent before the lease’s expiration date unless the lease agreement itself allows for an increase.
• Month-to-month (periodic) tenancy: Landlords may raise the rent by giving proper written notice, but not during the period already covered by rent payments.

If you have a written lease for a specific term, your landlord is legally required to honor the agreed-upon rent amount until the end of your lease, unless your contract says otherwise.

Notice Requirements for Rent Increases

For most monthly or periodic tenants in Connecticut, the landlord must provide at least 3 full days’ written notice before the start of a new rental period if they intend to raise your rent (General Statutes § 47a-23).^[2] However, during a fixed-term lease, they must wait until renewal.

Exceptions & Special Circumstances

• Check your lease: Some leases include clauses about rent increases for utilities or property tax changes. Read your agreement carefully.
• Subsidized housing or public assistance: Different rules may apply if your rent is subsidized. Contact your housing authority for more details.

If Your Landlord Raises Rent Illegally

If your landlord attempts to increase your rent during a fixed-term lease without proper cause or notice, Connecticut law considers this unenforceable.

What Forms or Steps Should Renters Know?

While there’s no specific Connecticut state form for disputing an illegal rent increase mid-lease, renters can:

• Use the Notice to Landlord (no standard form) — write a letter stating you believe the increase is illegal, referencing your lease and the applicable Connecticut law.
• If retaliation or attempted eviction occurs, you may respond with Appearance form JD-CV-126 if you receive eviction papers. This form lets you participate in eviction proceedings and assert your defenses.
  Example: After getting a "Notice to Quit" following a rent dispute, file the Appearance form within the stated deadline to ensure your side is heard in court.

Which Tribunal Handles Rental Disputes in Connecticut?

In Connecticut, residential tenancy disputes — including those about rent increases or lease violations — are handled by the Connecticut Superior Court - Housing Session.^[3] You may need to attend if a complaint or eviction is filed by your landlord or yourself.
