Yes, it is legal to get the first month plus two month's security deposits in CT. I've had excellent results doing this for the past 10 years compared to when I first started out as a landlord and got 1st, last, plus security and had some of the problems you describe.
Here is what the CT Banking Commission website states:
What Is A Security Deposit?
A security deposit is any advance rental payment other than an advance for the first month's rent or a deposit for a key or any special equipment. A security deposit remains the tenant's property but the landlord holds a security interest in it. Security deposits must be kept in an escrow account in a Connecticut bank.
How Large A Security Deposit Can A Landlord Require?
Landlords can't require more than two months rent as a security deposit. This limit is reduced to one month's rent if a tenant is 62 years of age or older.
Do Landlords Pay Tenants Interest On Security Deposits?
Yes. Landlords must pay tenants interest on security deposits of at least the average commercial banks savings deposit rate as annually determined and published by the Banking Commissioner. Interest must be paid annually on the anniversary date of a tenancy either directly to tenants or as a credit towards the next month's rent. (2009 interest is 1.5%)
When Do Landlords Have To Return Security Deposits?
Landlords must return security deposits with interest or give tenants written notice of damages being claimed within thirty days of when tenants move. The only exception is if a tenant fails to provide a written forwarding address: landlords then need not return security deposits or provide a notice of damages until fifteen days after receipt of a forwarding address in writing.
If a landlord does not return a security deposit with interest or provide a written notice of damages within these statutory time limits, the landlord may have to pay the tenant twice the amount of the security deposit. Tenants may pursue this remedy in court. For further information, see the section on options for resolving disputes.
A landlord's written notice of damages must itemize the nature and amount of tenant damages, including any unpaid rent or utility payments, and must be accompanied by the balance, if any, of the tenant's security deposit not being claimed for damages plus interest.
