Security deposits are one of the most regulated parts of being a landlord in Connecticut, and one of the most common sources of disputes. Getting the details right protects both your money and your reputation. Getting them wrong can expose you to penalties well beyond the deposit itself.
Here's an overview of the key rules Connecticut landlords should know. This is general information, not legal advice. Statutes change, so confirm current requirements with an attorney or a professional manager.
Key Takeaways
- Connecticut caps security deposits at two months' rent, or one month's rent for tenants aged 62 or older.
- Deposits must be held in an escrow account at a financial institution, and tenants earn interest on them.
- After move-out, landlords must return the deposit or send an itemized list of deductions within the statutory deadline.
- Good documentation through move-in and move-out inspections is your best defense in any dispute.
How Much Can You Collect?
In Connecticut, a security deposit generally can't exceed two months' rent. For tenants who are 62 or older, the limit is one month's rent. If a tenant turns 62 during the tenancy, they may be entitled to a refund of any amount above one month's rent.
Escrow and Interest
Connecticut requires landlords to hold security deposits in an escrow account at a financial institution, separate from their own funds. Tenants are entitled to interest on their deposit at a rate set annually by the state Banking Commissioner. Interest is typically credited or paid to the tenant each year on the anniversary of the tenancy. Missing the interest payments is one of the most common landlord mistakes.
Returning the Deposit
After a tenant moves out, Connecticut law requires the landlord to return the deposit plus accrued interest, or provide an itemized statement of damages and deductions along with any balance due, within a set number of days after the tenancy ends or after receiving the tenant's forwarding address in writing, whichever is later. The deadline was shortened in recent years, which surprised many landlords, so check the current statute. Failing to comply can expose landlords to a penalty of up to twice the deposit amount.
What Can Be Deducted?
Landlords may deduct unpaid rent and the cost of repairing damage beyond normal wear and tear. Normal wear and tear, such as minor scuffs, faded paint, or carpet wear from ordinary living, generally can't be charged to the tenant. The difference is often where disputes start.
Documentation Is Everything
- Move-in inspection: Detailed, date-stamped photos and a written checklist signed by the tenant
- Periodic inspections: Catch issues early and document conditions over time
- Move-out inspection: Compare against the move-in record room by room
- Receipts and invoices: Support every deduction with actual repair costs
Common Mistakes to Avoid
- Mixing deposits with operating funds
- Forgetting annual interest
- Missing the return deadline
- Deducting for normal wear and tear
- Collecting more than the legal maximum
- Failing to transfer deposits correctly when a property is sold

Can I use the security deposit for last month's rent?
The deposit is meant to secure performance of the lease. Discuss handling with your manager or attorney rather than agreeing informally.
