How to Write a Demand Letter to Your Landlord in Connecticut

If you’re a renter in Connecticut facing unresolved issues with your landlord—such as overdue repairs, unreturned deposits, or violations of your lease—you may need to formally communicate your concerns. Writing a demand letter is a common and effective first step. In Connecticut, this process helps clarify your position, strengthens your case if legal action is needed, and often resolves disputes quickly without going to court. Below, we’ll break down what a demand letter is, what to include, and where to find official resources so you can take confident, informed action.

What Is a Demand Letter?

A demand letter is a written notice from a tenant to their landlord that details the problem, requests a solution, and gives a reasonable deadline to respond. This letter can be used for various issues, such as requesting repairs, disputing fees, asking for the return of a security deposit, or objecting to unlawful rent increases.

When Should You Send a Demand Letter?

Connecticut renters often use demand letters for matters like:

  • Maintenance not performed after a reasonable request period (like lack of heat or plumbing repairs)
  • Security deposit not returned within 30 days of moving out
  • Disputes over lease terms or charges
  • Requesting documentation or communications from the landlord

It’s usually best to try to resolve issues informally first, but a formal letter is an important record if you need to escalate.

What to Include in Your Demand Letter

  • Date and landlord’s name and address.
  • Your name, address, and contact information.
  • Clear description of the issue: Be specific (e.g., "The heater hasn’t worked since January 15, 2024").
  • Reference to previous conversations or written notices, if any.
  • The remedy you are requesting: What do you want to happen? (e.g., "Repair the heater" or "Return my $1,200 security deposit").
  • A reasonable deadline (usually 10–15 days).
  • Statement of possible next steps: For example, that you may contact a local housing authority, file a complaint, or pursue legal action if there’s no response.
  • Your signature.
For best results, mail your demand letter by certified mail and keep a copy for your records. This provides proof that you contacted your landlord and strengthens your position if escalation is needed.

Official Forms and Sample Letters

Connecticut does not require a specific statewide form for demand letters, but there are official sample templates that can help you get started. For security deposit disputes, see these official resources:

  • Security Deposit Dispute Resolution Form (DCP-LT-02) — This is used when your landlord fails to return your deposit within 30 days of lease termination. Fill out the form and submit it as directed, usually after sending your own written demand letter.
    • When to use: If your landlord has not returned your deposit and hasn't responded to your letter within 30 days after your lease ended.

The Connecticut Department of Consumer Protection (DCP) provides further sample letters and guidance. Always check the latest recommendations and requirements based on your particular issue.

Important Connecticut Legislation and Oversight Bodies

Connecticut’s primary rental housing law is the Connecticut General Statutes Chapter 832 – Landlord and Tenant Law. Many disputes are handled by the Housing Session of the Connecticut Superior Court, which acts as the official tribunal for residential tenancy matters. You can learn more or find court locations on the Connecticut Judicial Branch Housing Session site.
