Delaware Security Deposit Laws: What Landlords Must Know (2026)

Quick Answer

Delaware has a cap of one month’s rent on security deposits for unfurnished residential rentals, though furnished units may warrant higher deposits. Landlords must return deposits within 20 days of lease termination (with itemized deductions) and hold deposits in a separate escrow account. Failure to follow these rules can result in forfeiture of the right to retain any deposit amount.

The Full Picture: Delaware Security Deposit Rules

Maximum Deposit Amount

Here’s the quick breakdown from §5514 of the Delaware Landlord-Tenant Code:

• Standard residential leases (1 year or more): Max 1 month’s rent
• Month-to-month or undefined term after 1+ year: Also capped at 1 month’s rent — and if you collected more upfront, you must return the excess as a credit once the tenancy hits the 1-year mark.
• Furnished units: The cap does not apply — you can charge more.
• Pet deposit: Separate from security deposit, also capped at 1 month’s rent. Cannot require one for certified support animals.

The 20-Day Rule

Delaware law (25 Del. C. § 5514) is strict:

“The security deposit… shall be returned to the tenant within 20 days after the termination of the rental agreement…”

Key details:

• Clock starts when the tenant surrenders the property (returns keys, vacates completely)
• If you’re making deductions, you must provide an itemized list within those 20 days
• Failure to meet the deadline means you forfeit the right to retain any portion of the deposit
• The deposit must be returned by mail to the forwarding address provided by the tenant

What counts as “itemized?”

• Specific descriptions of damage (not just “cleaning: $200”)
• Copies of receipts or invoices for repairs
• Reasonable estimates for work not yet completed (must be followed up with actual receipts)

Escrow Account Requirement

Security deposits must be held in a separate, interest-bearing account distinct from the landlord’s operating funds.

Requirements:

• Account must be in a Delaware financial institution
• Must be labeled as a security deposit account
• Cannot be commingled with rent or other income
• Interest (if any) belongs to the landlord unless otherwise agreed

Pro tip: Many landlords skip this step, but it’s a legal requirement. Commingling deposits with operating funds can expose you to liability.

Allowed vs. Prohibited Deductions

What You CAN Deduct

What You CANNOT Deduct

Normal wear and tear vs. damage:

Move-In and Move-Out Inspections

Move-In Inspection

Best practices:

• Conduct within 48 hours of move-in
• Use a detailed checklist (we provide one)
• Take dated photos of every room, appliance, and existing damage
• Have tenant sign the inspection report
• Provide tenant a copy

Why it matters: This is your baseline. Without documentation, you cannot prove damage occurred during this tenancy.

Move-Out Inspection

Process:

• Schedule within 24-48 hours of move-out
• Use the same checklist as move-in
• Compare condition to move-in photos
• Take photos of any damage
• Tenant has the right to be present (though they often decline)

Timeline pressure: Remember, you have 20 days total from move-out to return the deposit. Don’t delay the inspection.

Handling Security Deposit Disputes

When Tenants Disagree

If a tenant disputes your deductions:

1. Review your documentation – Do you have photos, receipts, and the signed move-in report?
2. Communicate clearly – Explain the specific damages and provide copies of receipts
3. Offer compromise – Sometimes partial refund resolves the dispute faster than small claims court
4. Document everything – Save all emails, texts, and notes from phone calls

Small Claims Court

If you can’t resolve the dispute:

• Tenants can sue in Delaware Justice of the Peace Court
• Jurisdiction: Up to $15,000
• Landlord-tenant cases often move quickly
• If the court finds you willfully withheld the deposit, you may owe damages

Reality check: Most deposit disputes are won or lost based on documentation. The landlord with photos, receipts, and signed inspection reports usually prevails.

Pet Deposits and Fees

Pet Deposits

• Separate from security deposit
• Refundable (typically) if no pet damage
• Not subject to the 20-day rule (can be held longer to assess damage)

Pet Rent

• Monthly fee for having a pet (typically $25-50/month)
• Non-refundable
• Must be disclosed in lease

Important: You cannot charge pet deposits or pet rent for service animals or emotional support animals. These are accommodations, not pets, under Fair Housing law.

Common Mistakes Delaware Landlords Make

1. Missing the 20-day deadline – This is the #1 way to lose your right to retain deposits
2. Not itemizing deductions – “Cleaning: $300” isn’t enough detail
3. Failing to document move-in condition – You can’t prove damage without before photos
4. Commingling deposits – Mixing security deposits with operating funds violates Delaware law
5. Charging for normal wear and tear – Leads to disputes and potential legal action

The Bottom Line

Security deposits are not extra income—they’re the tenant’s money held in trust. Treat them accordingly:

• Hold deposits in a separate account
• Document everything at move-in and move-out
• Return deposits within 20 days with itemized deductions
• Only deduct for actual damage beyond normal wear and tear

Following these rules protects you from disputes and ensures you can legally retain funds when tenants cause damage.
