HB 1299 amends the Property Code to clarify the definition of security deposits in residential leases. It establishes that any refundable or non-refundable fee or charge required for damages, regardless of how it is labeled, is presumed to be a security deposit. The bill also applies this presumption to any deposits required during the lease term, providing clearer standards for tenant and landlord financial interactions in residential leases. These provisions apply only to leases entered into or renewed after the bill's effective date.
