How Much Can a Landlord Charge for a Security Deposit in Connecticut?
Legal basis: Conn. Gen. Stat. Ann. § 47a-21(b) & (d).
How Connecticut Security Deposit Limits Work
Under Connecticut General Statutes § 47a-21, landlords may collect a maximum of two months' rent as a security deposit — but this cap drops to one month's rent if the tenant is 62 years of age or older. This age-based distinction is one of the most significant deposit protections in the northeastern United States and applies automatically based on the tenant's age at the time of the lease.
Connecticut imposes a 21-day return deadline after move-out, with an important nuance: if the tenant provides a forwarding address in writing, the deadline is 21 days or 15 days after the landlord receives that forwarding address, whichever is later. The deposit must be held in a separate escrow account at a Connecticut bank, and the landlord must provide the tenant with written notice of the bank name and address.
Interest on the security deposit accrues at a rate set annually by the Banking Commissioner (0.49% for 2026) and must be paid to the tenant annually or credited toward rent. Failure to comply with deposit requirements may expose the landlord to double (2×) damages under § 47a-21(d)(2).
Example: Is Your CT Deposit Legal?
Your monthly rent is $1,500 and your landlord collected $3,200 as a security deposit. You are 58 years old.
Your landlord collected $200 more than the 2-month cap allows. If you were 62 or older, the cap would be $1,500 (1 month) — making the overcharge $1,700.
Frequently Asked Questions
What is the maximum security deposit in Connecticut? ▼
For tenants under 62: the maximum is two months' rent. For tenants 62 or older: the maximum is one month's rent. This age-based distinction is set by § 47a-21(b) and cannot be overridden by the lease.
Does the Connecticut 62+ deposit limit apply to all rentals? ▼
Yes. The one-month cap for tenants 62 and older applies to all residential rentals in Connecticut — apartments, houses, condos, and any other dwelling. There are no exceptions for furnished units, luxury properties, or buildings of any particular size.
How long does a Connecticut landlord have to return my deposit? ▼
The landlord has 21 days after you move out to return your deposit, or 15 days after receiving your written forwarding address, whichever is later. The deposit must include any accrued interest. If the landlord makes deductions, they must provide an itemized list.
What happens if my Connecticut landlord doesn't return my deposit? ▼
If your landlord fails to return your deposit within the required timeframe or improperly withholds it, you may be entitled to double (2×) damages under § 47a-21(d)(2). This means the court can award you twice the amount wrongfully withheld, plus reasonable attorney's fees.
