Governing Laws

Most residential rentals in Delaware fall under the umbrella of Title 25. The code governs everything from security deposit caps and late fee limits to specific eviction timelines and required disclosures.

A unique requirement in Delaware is that landlords must provide new tenants with a "Summary of the Delaware Residential Landlord-Tenant Code," prepared by the Attorney General's Office, at the beginning of the lease term.

Landlord Obligations

Delaware landlords must strictly adhere to the following core responsibilities:

Implied Warranty of Habitability

Under Title 25, landlords have a strict duty to maintain the rental unit in a clean, safe, and habitable condition. This includes complying with all local housing codes, providing functioning plumbing, electrical, and heating systems, and maintaining common areas.

See our Maintenance Obligations guide for detailed information on what repairs are required by law.

Security Deposits and Fees

Delaware places firm limits on what a landlord can charge:

• Security Deposits: Capped at one month's rent for leases of one year or longer. (Furnished units are exempt from this cap).
• Late Fees: Capped at 5% of the monthly rent after a mandatory 5-day grace period.
• Application Fees: Capped at the greater of 10% of the monthly rent or $50.

For a full breakdown, read our guides on Security Deposits and Late Fees.

Required Notices Before Entry

Landlords must generally provide at least 48 hours' notice before entering a tenant's unit for non-emergencies (such as routine maintenance or showings). Entry is typically only permitted between 8:00 a.m. and 9:00 p.m.

Tenant Rights and Obligations

Rent Payment and Maintenance

Tenants in Delaware must pay rent on time and maintain the property in a clean and safe manner, disposing of garbage properly and not deliberately destroying any part of the premises.

Tenant Remedies

If a landlord fails to provide essential services (like heat or water) or fails to make required repairs within a specific timeframe (often 15 days after receiving written notice), Delaware tenants may have the right to:

1. Terminate the lease.
2. Deduct the cost of repairs from rent (up to a certain limit).
3. Sue for damages.

The Eviction Process

Evicting a tenant in Delaware requires strict adherence to statutory notice periods. "Self-help" evictions (like changing the locks or shutting off utilities) are entirely illegal.

• Non-Payment of Rent: Requires a 5-day written notice to pay or quit.
• Lease Violations: Generally require a 7-day written notice to cure the violation.
