Delaware Code
Subchapter II. Landlord-Tenant Relationship
§ 7017. Security deposits; pet security deposits.

(a) (1) A landlord may require a tenant to pay a security deposit if provided for in the rental agreement.
(2) A landlord may not require a tenant to pay a security deposit in an amount in excess of 1 month's rent unless the tenant agrees to do so and the full amount is specified in the rental agreement.
(b) (1) Every security deposit paid to a landlord must be placed by the landlord in an escrow bank account in a federally-insured financial institution with an office that accepts deposits within the State. The account must be designated as a security-deposits account and may not be used by the landlord for any purposes other than those described under subsection (c) of this section. The landlord shall disclose in the rental agreement the location of the security deposit account. If the landlord changes the location of the security deposit account, the landlord shall notify each tenant of the new location within 30 days of the change. Security deposit principal must be held and administered for the benefit of the tenant, and the tenant's claim to such money has priority over that of any creditor of the landlord, including a trustee in bankruptcy, even if such money is commingled.
(2) A security deposit paid pursuant to a new rental agreement signed on or after August 25, 2003, must be immediately escrowed under paragraph (b)(1) of this section. A security deposit paid as provided for in an existing rental agreement signed prior to August 25, 2003, must be escrowed under paragraph (b)(1) of this section on or before June 30, 2005.
(c) A security deposit may be used for any of the following purposes:

(1) To reimburse a landlord for actual damages which exceed normal wear and tear to the landlord's property and which were caused by the tenant.
(2) To pay a landlord for all rent, rent arrearage, fees, charges, Trust Fund assessments, and other moneys due and owed to the landlord by the tenant.
(3) To reimburse a landlord for all reasonable expenses incurred in renovating and re-renting the landlord's property caused by the premature termination of the rental agreement by the tenant, except for termination under § 7021 of this title.
(d) Within 20 days after the expiration or termination of a rental agreement, the landlord shall provide the tenant with an itemized list of damages, if any, to the landlord's property and the estimated cost of repair for each item. The landlord shall tender payment for the difference between the security deposit and the cost for repair of damage to the landlord's property. Failure to do so constitutes an acknowledgment by the landlord that no payment for repair of damage is due. A tenant's acceptance of a payment submitted with an itemized list of damages constitutes agreement on the damages as specified by the landlord, unless the tenant objects in writing within 10 days of receipt of the landlord's tender of payment to the amount withheld by the landlord.
(e) If a landlord is not entitled to all or any portion of a security deposit, the landlord shall remit to the tenant within 20 days of the expiration or termination of the rental agreement the portion of the security deposit to which the landlord is not entitled.
(f) Penalties. —
(1) Failure by a landlord to remit to a tenant the security deposit or the difference between the security deposit and the cost for repair of damage within 20 days from the expiration or termination of the rental agreement entitles the tenant to double the amount wrongfully withheld.
(2) Failure by a landlord to disclose the location of the security deposit account within 20 days of a written request by a tenant or failure by a landlord to deposit a security deposit in a federally-insured financial institution with an office that accepts deposits within the State results in forfeiture of the security deposit by the landlord to the tenant. Failure by a landlord to return the full security deposit to a tenant under this paragraph within 20 days from the effective date of forfeiture entitles the tenant to double the amount of the security deposit.
(g) All communications and notices required under this section must be directed to a landlord at the address specified in the rental agreement and to a tenant at an address specified in the rental agreement or at a forwarding address, if a forwarding address was provided to the landlord in writing by the tenant. Failure by a tenant to provide a forwarding address relieves the landlord of the responsibility to give notice pursuant to this section and removes the landlord's liability for double the amount of the security deposit. However, the landlord continues to be liable to the tenant for any unused portion of the security deposit if, within 1 year from the expiration or termination of the rental agreement, the tenant makes a claim in writing to the landlord.
(h) Pet deposits. —
(1) A landlord may require a tenant to pay a pet security deposit for each pet if provided for in the rental agreement. Damage to a landlord's property caused by a tenant's pet must first be deducted from the pet security deposit. If the pet deposit is insufficient, pet damages may be deducted from the tenant's nonpet security deposit.
(2) If a nonpet security deposit is insufficient to cover nonpet damages under subsection (c) of this section, damages may be deducted from the pet security deposit even if such damages were not caused by a pet. A pet security deposit is a type of security deposit and is subject to subsections (b), (d), (e), (f), and (g) of this section.
(3) A landlord may not require a tenant to pay a pet security deposit in an amount in excess of 1 month's rent, unless the tenant agrees to do so and the full amount is specified in the rental agreement.
(4) A landlord may not require a pet security deposit from a tenant if the pet is a certified and trained support animal for a person with a disability who is a resident of a manufactured home on a rented lot.
(5) Notwithstanding legal ownership of a pet, for purposes of this subchapter, a pet that resides in a manufactured home, or on the lot where the home is located in a manufactured home community, is deemed owned and controlled by a tenant who resides in the manufactured home.
(i) If a rental agreement so specifies, a landlord may increase a security deposit commensurate with an increase in rent. If an increase of the security deposit exceeds 10 percent of the monthly rent, the tenant may choose to pay the increase in the security deposit prorated over the term of the rental agreement but not to exceed 12 months, except in the case of a month-to-month tenancy, in which case payment of the increase may not be prorated over a period in excess of 4 months unless mutually agreed to by the landlord and tenant.
