SECTION 1.  Section 15B of chapter 186 of the General Laws, as appearing in the 2018 Official Edition, is hereby amended in subsection (b) of subsection (1) by inserting after the words “subsection (2)” in line 25 the following:-

provided however, in lieu of requiring payment of a security deposit a lessor may choose to collect and a tenant may choose to pay a fee in lieu of security deposit, the payment of which satisfies the lessor’s security deposit requirement and the tenant’s security deposit obligation. The fee in lieu of security deposit: (a) may be entirely or partially non-refundable, so long as this is disclosed in the lease and separately acknowledged by the tenant; (b) may be utilized by the lessor to purchase insurance coverage for unpaid rent or unit damage; (c) may be a recurring monthly fee, or payable upon any schedule and in any amount that the lessor and tenant choose; and (d) shall not be considered by a court, arbitrator, mediator or any other dispute resolution adjudicator to be a security deposit or governed by state or local codes governing security deposits.  If a lessor chooses to waive a security deposit requirement and a tenant agrees instead to pay a fee in lieu of a security deposit, the lessor shall: (a) ensure that the fee in lieu of a security deposit is strictly optional for the tenant, and the tenant can choose to pay a full security deposit rather than a fee in lieu of a security deposit; (b) not use a prospective tenant’s choice to pay a fee in lieu of a security deposit or a traditional security deposit as a criterion in the determination of whether to approve an application for occupancy; (c) if it chooses to offer the fee in lieu of a security deposit option, offer it to every prospective tenant whose application for occupancy has been approved, without further regard to income, race, gender, disability, sexual orientation, immigration status, size of household, or credit score following such approval, and; (d) allow any tenant that agrees to pay a fee in lieu of a security deposit, to opt-out of the continuing fee in lieu of a security deposit obligation upon full payment of the security deposit that is otherwise in effect for the tenant’s apartment on the day of the opt-out;
