Frequently Asked Questions: Connecticut Landlord Security Deposit & Deduction Calculator
What is the maximum security deposit a landlord can charge in Connecticut?
In Connecticut (CT), the standard residential security deposit benchmark cap is 2 month(s) of rent (some municipalities or unfurnished/furnished units may have specific rules; always verify local county/city ordinances).
How many days does a landlord in Connecticut have to return a security deposit?
Landlords in Connecticut have a strict 21-day statutory window after lease termination and key surrender to return the security deposit and/or mail a written itemized statement of deductions.
How do you calculate prorated carpet or paint depreciation for security deposit deductions?
Courts disallow charging a tenant 100% of replacement cost for an aged item. Multiply the replacement cost by ((Useful Life − Current Age) ÷ Useful Life).
