Under the terms of a lease agreement, a landlord holds a tenant’s security deposit “in trust” for the tenant. “[A] security deposit, whether commercial or residential, is the tenant’s property and . . . the landlord holds it for the tenant’s benefit subject to the tenant’s fulfilling all its obligations under the lease. Indeed, a security deposit by definition is [m]oney deposited by tenant with landlord as security for full and faithful performance by [the] tenant of [the] terms of lease, including damages to premises. It is refundable unless the tenant has caused damage or injury to the property or has breached the terms of the tenancy or the laws governing the tenancy.” (Emphasis added; internal quotation marks omitted.) Beal Bank, S.S.B. v. Airport Industrial Ltd. Partnership, 74 Conn. App. 460, 463, 812 A.2d 866 (2003). Construing the facts alleged in the revised amended complaint in the manner most favorable to sustaining its legal sufficiency, we conclude that the court should have denied the motion to strike the complaint as it relates to the plaintiffs claim for the return of the security deposit because the complaint supported a cause of action.
