3.3 Connecticut Landlord-Tenant & Common Interest Ownership

Key Takeaways

  • Connecticut's security deposit cap is 2 months' rent for most tenants and 1 month's rent for tenants age 62 and older (CGS Sec. 47a-21).
  • The landlord must hold deposits in an escrow account, pay annual interest at the deposit-index rate, and return the deposit within 30 days of termination or 15 days after receiving the tenant's forwarding address, whichever is later.
  • The Common Interest Ownership Act (CIOA, CGS Sec. 47-200 et seq.) governs condominiums, cooperatives, and planned communities in Connecticut.
  • A resale of a unit requires the seller to deliver a resale certificate (and a public offering statement for new units) disclosing budget, fees, liens, and restrictions (CGS Sec. 47-270).
  • Connecticut adverse possession and prescriptive easements require 15 years of continuous use under CGS Sec. 52-575.

Security Deposits (CGS Sec. 47a-21)

Leasing questions on the Connecticut state portion almost always hinge on the security-deposit statute, CGS Sec. 47a-21. Lock in the dollar limits, the interest rule, and the return clock.

Maximum Deposit

TenantMaximum security deposit
Most tenants2 months' rent
Tenants age 62 or older1 month's rent

Trap: If a landlord already holds a 2-month deposit and the tenant turns 62, the landlord must, on the tenant's written request, refund the amount exceeding one month's rent. The age-62 cap is the single most-tested deposit number in Connecticut.

Holding, Interest, and Return

RequirementRule
Where heldEscrow account in a Connecticut financial institution, separate from the landlord's funds
InterestLandlord pays annual interest at the rate set for deposit accounts (the statutory deposit-index rate), credited or paid each year
Return deadlineWithin 30 days of tenancy termination, or 15 days after the landlord receives the tenant's forwarding address — whichever is later
DeductionsOnly for unpaid rent and damage beyond ordinary wear and tear, with an itemized statement

Worked example: A tenant moves out March 31 and gives the landlord a forwarding address on April 20. The 30-day clock from March 31 ends April 30; the 15-day clock from April 20 ends May 5. Because the rule is "whichever is later," the landlord has until May 5 to return the deposit with interest and any itemized deductions. Miss it, and the tenant may recover double the deposit.

Other Leasing Points

  • No statutory grace period for rent by default, but a 9-day grace period applies before a late fee or eviction for nonpayment on most residential leases.
  • Eviction ("summary process") is a court action; Connecticut landlords may not use "self-help" (changing locks, removing belongings, shutting off utilities). Lockouts are illegal.
  • Connecticut has no counties, so eviction and housing matters are heard in the Superior Court Housing Session or the regular Superior Court for the judicial district.

The Common Interest Ownership Act (CIOA)

Many Connecticut transactions involve a common interest community — a condominium, cooperative, or planned community where owners share ownership of common elements and pay association fees. These are governed by the Common Interest Ownership Act (CIOA), CGS Sec. 47-200 et seq., Connecticut's comprehensive condo/HOA statute.

Community typeWhat the buyer owns
CondominiumThe individual unit plus an undivided interest in common elements
CooperativeShares in a corporation that owns the building, plus a proprietary lease
Planned community (PUD)A lot/home plus membership in the association that owns common areas

Required Disclosures on a Resale

Under CGS Sec. 47-270, when an existing unit is resold, the seller must deliver to the buyer a resale certificate prepared with the association's help. For a new unit sold by a declarant, the buyer instead receives a public offering statement. The resale certificate discloses:

DisclosureWhy it matters
Current common-expense (HOA) fees and assessmentsBuyer's ongoing monthly cost
Any unpaid assessments or liens against the unitCould transfer to the buyer
The association budget and reservesFinancial health of the community
Special assessments approved or anticipatedLarge upcoming charges (e.g., roof, capital projects over $1,000)
Rules, restrictions, and litigationPet limits, rental caps, pending lawsuits

Timing rule: On a unit owner's request, the association must furnish the information needed for the certificate within 10 business days. The buyer's review of the resale package is a common contingency, and delivering it late or incomplete can give the buyer a cancellation right.

Adverse Possession and Prescriptive Easements

Connecticut recognizes that long, open use of land can ripen into rights. Under CGS Sec. 52-575, the period is 15 years.

DoctrineWhat it transfersCT requirement
Adverse possessionTitle/ownership of the land15 years of use that is open, notorious, exclusive, continuous, and hostile (without permission)
Prescriptive easementA right to use another's land (not ownership)15 years of open, continuous, adverse use

Trap: Permission defeats both doctrines. If the true owner gives permission, the use is not "hostile," and the clock never runs. A common exam scenario: a neighbor who has crossed a driveway "with the owner's blessing" for 20 years gains no prescriptive easement.

Quick Reference: Connecticut Numbers in This Section

ItemValue
Security deposit (most tenants)2 months' rent
Security deposit (age 62+)1 month's rent
Deposit return30 days, or 15 days after forwarding address (later)
Late-rent grace period9 days
Resale-certificate turnaround10 business days
Adverse possession / prescriptive easement15 years

Exam tip: When a landlord-tenant question gives a tenant's age, check the 62-and-older deposit cap first. When a condo question appears, the answer almost always involves the resale certificate and the association fees/liens it discloses.
