Connecticut Tenants’ Mold Rights and Landlord Duties

Mold can quickly turn a safe rental apartment into a health hazard. If you’re a renter in Connecticut, understanding how state laws protect you against mold, and what steps you can take, can help you maintain a safe living space while maintaining a good tenant-landlord relationship. This guide covers your rights, your landlord's obligations, and the steps to address mold issues in your rental home.

Your Rights as a Connecticut Renter Facing Mold Issues

In Connecticut, landlords must provide and maintain rental units that are safe and livable. This includes a duty to address serious issues like mold that could affect your health or safety. You have legal protections under Connecticut’s landlord-tenant laws if mold in your rental makes the apartment uninhabitable.

  • Landlords must keep your rental unit in good repair and address conditions that threaten health (Connecticut General Statutes § 47a-7).
  • You’re entitled to “the right to a habitable apartment,” which includes freedom from unsafe mold or water leaks.
  • You must notify your landlord about the problem in writing to trigger their repair obligations.

What Counts as an Unlivable or Unsafe Condition?

Mold can be considered an unlivable condition if it is extensive or results from leaks, poor ventilation, or other persistent water problems. If mold is found, especially in places where you did not cause the issue, it’s the landlord’s responsibility to fix the underlying cause and properly clean the mold.

How to Notify Your Landlord and Request Mold Repairs

When you spot mold, Connecticut law requires renters to inform landlords about problems that threaten health or safety. It’s best to use written notice so you have a record. Below is the official form:

  • Form Name: Connecticut Notice to Landlord of Violation of § 47a-7 (No official state form number)
  • When to Use: If your apartment has unsafe mold and needs urgent repairs.
  • How to Use: Write your name, address, a description of the mold issue, and request prompt repairs. Send it to your landlord and keep a copy for your records.
  • Connecticut Judicial Branch Housing Matters Forms (official site)

If the landlord does not address the mold problem after your written notice, you may have the right to withhold rent or ask a local housing code enforcement agency for help.

If Repairs Are Not Made: Legal Remedies and Escalation

If your landlord has not responded to a proper written notice about mold, Connecticut law gives renters next steps, including contacting the local housing code office or applying to the state’s housing court. You must continue to pay rent unless a court or official tells you otherwise.

Filing a Complaint or Taking Action

The court may order the landlord to fix the problem or allow rent payments to be placed in court (“rent escrow”) until repairs are made.

Summary of the Legal Process

Most mold disputes are resolved by notifying the landlord and requesting repairs. If that doesn't work, contacting the health department or housing court can lead to legally enforceable repairs or other remedies.

Always document mold problems with dated photos and written communication to your landlord. This will help protect your rights if you need to go to court.

Connecticut’s Landlord and Tenant Laws That Protect Renters

The primary law protecting renters’ rights and outlining landlord duties and tenant remedies is the Connecticut General Statutes Chapter 832 – Landlord and Tenant. This law spells out:

  • Your right to a habitable living space (Section 47a-7)
  • The landlord’s duty to repair unsafe conditions promptly
  • How renters can proceed if repairs are not made

The official tribunal handling rental disputes is the Connecticut Superior Court, Housing Session.
