(2) Each landlord and each successor to the landlord’s interest shall maintain each such account as escrow agent and shall not withdraw the amount of any security deposit or accrued interest on such amount, as provided in subsection (i) of this section, that is in any escrow account from such account except as provided in this section.

If at the time of transfer of such real estate the funds in such account are commingled with security deposits paid by tenants in real estate not being transferred to such successor, and if at such time the funds in such account are less than the amount of security deposits paid by all tenants whose security deposits are contained in such account, such landlord shall deliver to such successor a pro rata share of security deposits paid by tenants of the real estate being transferred to such successor. Any successor to a landlord shall immediately deposit the entire amount of funds delivered to him in accordance with this subdivision into an escrow account as provided in subdivision (l) of this subsection and shall maintain such account as escrow agent in accordance with the provisions of this section. (B) Whenever any real estate is transferred from a receiver to his successor, such receiver shall dispose of the escrow accounts as ordered by the court which appointed him receiver. The order of such court shall provide for the priority of the present and future rights of tenants to security deposits paid by them over the rights of any secured or unsecured creditor of any person and shall provide that the funds in such account shall be delivered to the successor of such receiver for immediate deposit in an escrow account for tenants who paid security deposits.

(4) No person shall withdraw funds from any escrow account except as follows: (A) Within the time specified in subsection (d) of this section, each escrow agent shall withdraw and disburse the amount of any security deposit due to any tenant upon the termination of such tenancy, in accordance with subsection (d) of this section, together with accrued interest thereon as provided in subsection (i) of this section. (B) At the time provided for in subsection (i) of this section, each escrow agent shall withdraw from such account and pay to each tenant any accrued interest due and payable to any tenant in accordance with the provisions of said subsection. (C) The escrow agent may withdraw and personally retain interest credited to and not previously withdrawn from such account to the extent such interest exceeds the amount of interest being earned by tenants as provided in subsection (i) of this section.

(G) The escrow agent may transfer any escrow account from one financial institution to another and may transfer funds from one escrow account to another provided that all security deposits in escrow accounts remain continuously in escrow accounts.

(i) Payment of interest on security deposits. (1) On and after July 1, 1993, each landlord other than a landlord of a residential unit in any building owned or controlled by any educational institution and used by such institution for the purpose of housing students of such institution and their families, and each landlord or owner of a mobile manufactured home or of a mobile manufactured home space or lot or park, as such terms are defined in subdivisions (1), (2) and (3) of section 21-64, shall pay interest on each security deposit received by such landlord at a rate of not less than the average rate paid, as of December 30, 1992, on savings deposits by insured commercial banks as published in the Federal Reserve Board Bulletin rounded to the nearest one-tenth of one percentage point, except in no event shall the rate be less than one and one-half per cent. On and after January 1, 1994, the rate for each calendar year shall be not less than the deposit index, as defined in subdivision (2) of this subsection, for that year, except in no event shall the rate be less than one and one-half per cent. On and after January 1, 2012, the rate for each calendar year shall be not less than the deposit index, as defined in subdivision (2) of this subsection, for that year. On the anniversary date of the tenancy and annually thereafter, such interest shall be paid to the tenant or resident or credited toward the next rental payment due from the tenant or resident, as the landlord or owner shall determine. If the tenancy is terminated before the anniversary date of such tenancy, or if the landlord or owner returns all or part of a security deposit prior to termination of the tenancy, the landlord or owner shall pay the accrued interest to the tenant or resident not later than thirty days after such termination or return. In any case where a tenant or resident has been delinquent for more than ten days in the payment of any monthly rent, such resident or tenant shall forfeit any interest that would otherwise be payable to such resident or tenant for that month, except that there shall be no such forfeiture if, pursuant to a provision of the rental agreement, a late charge is imposed for failure to pay such rent within the time period provided by section 47a-15a. No landlord or owner shall increase the rent due on any quarters or property subject to the provisions of this section because of the requirement that interest be paid on any security deposit made with respect to such quarters or property.

(2) The commissioner shall publish the rate that takes effect July 1, 1993, in the Department of Banking news bulletin no later than July 15, 1993. The deposit index for each calendar year shall be equal to the average rate paid on savings deposits by insured commercial banks as last published in the Federal Reserve Board Bulletin in November of the prior year. The commissioner shall determine the deposit index for each calendar year and publish such deposit index in the Department of Banking news bulletin no later than December fifteenth of the prior year. The commissioner shall also cause such rates to be disseminated in a manner designed to come to the attention of landlords and tenants including, but not limited to, the issuance of press releases and public service announcements, the encouragement of news stories in the mass media and the posting of conspicuous notices at financial institutions. For purposes of this subsection, “Federal Reserve Board Bulletin” means the monthly survey of selected deposits published as a special supplement to the Federal Reserve Statistical Release Publication H.6 published by the Board of Governors of the Federal Reserve System or, if such bulletin is superseded or becomes unavailable, a substantially similar index or publication.

(j) Investigation of complaints by commissioner. Order. Enforcement. Regulations. (1) The commissioner may receive and investigate complaints regarding any alleged violation of subsections (b), (d), (h) or (i) of this section, provided the commissioner shall not have jurisdiction over the refusal or other failure of any landlord to return all or part of a security deposit if such failure results from the landlord’s good faith claim that the landlord has suffered damages as a result of a tenant’s failure to comply with such tenant’s obligations whether or not the existence or amount of alleged damages is disputed by the tenant. For purposes of this section a good faith claim is deemed to be a claim for actual damages suffered by the landlord for which written notification of such damages has been given to the tenant in accordance with the provisions of subdivisions (1), (2) and (4) of subsection (d) of this section. For the purposes of such investigation, any person who is or was a landlord shall be subject to the provisions of section 36a-17.

(3) The commissioner may adopt regulations, in accordance with chapter 54, to carry out the purposes of this section.

(k) Penalties. (1) Any person who is a landlord at the time of termination of a tenancy and who knowingly and wilfully fails to pay all or any part of a security deposit when due shall be subject to a fine of not more than two hundred fifty dollars for each offense, provided it shall be an affirmative defense under this subdivision that such failure was caused by such landlord’s good faith belief that he was entitled to deduct the value of damages he has suffered as a result of such tenant’s failure to comply with such tenant’s obligations.

(2) Any person who knowingly and wilfully violates the provisions of subsection (h) of this section on or after October 1, 1979, shall be subject to a fine of not more than five hundred dollars or imprisonment of not more than thirty days or both for each offense.

(3) Any person who is a landlord at the time an interest payment is due under the provisions of subsection (i) of this section and who knowingly and wilfully violates the provisions of such subsection shall be subject to a fine of not more than one hundred dollars for each offense.
