Delaware (DE) law guide
Delaware's **Residential Landlord-Tenant Code** (Title 25, Chapters 51 through 57) governs every aspect of the rental relationship in the First State, from the moment a deposit changes hands through the final day of tenancy. The Code strikes a notably balanced posture: landlords receive clearly defined remedies for nonpayment and lease violations, while tenants benefit from a robust warranty of habitability, a strict 20-day deposit-return window, and an explicit ban on self-help eviction. With roughly **28% of Delaware households renting** and the state's population crossing 1 million residents, the Code provides a compact but comprehensive framework suited to the state's mix of urban corridors and suburban communities.

Wilmington's two-bedroom median sits near $1,150, well below the statewide average, giving renters relative affordability within a state that enforces a hard one-month deposit cap on annual leases -- keeping upfront move-in costs predictable in a market where demand is rising along the I-95 corridor.
Delaware imposes a clear statutory ceiling on how much a landlord may collect upfront. Under 25 Del. C. § 5514, landlords may not require a security deposit exceeding one month's rent when the rental agreement runs for one year or longer. Month-to-month tenants can be charged more during the first year of occupancy, but once a full year has passed the landlord must immediately credit back any amount held above one month's rent. Pet deposits are treated separately and are also capped at one month's rent, regardless of lease length. Landlords must hold all deposits in a federally insured escrow account separate from their personal or business funds, and they must disclose the account's location to the tenant on request.
After the tenancy ends, a landlord has 20 days to return the deposit or provide a written, itemized list of deductions along with payment of any remaining balance. The list must specify each claimed damage and its estimated repair cost. Tenants who disagree with the deductions have 10 days to object in writing; silence within that window is treated as acceptance. If a landlord fails to meet the 20-day deadline, the tenant becomes entitled to double the amount wrongfully withheld under § 5514 -- a meaningful financial penalty that gives landlords strong incentive to act promptly. Normal wear and tear cannot be charged against the deposit, and any deductions must reflect actual documented damage beyond ordinary use.
Delaware has no statewide rent control or rent stabilization law, and no city or county in the state currently operates a local rent ordinance. Landlords may raise rent by any amount they choose, subject only to the notice requirements written into the Residential Landlord-Tenant Code. A proposed rent-cap bill (House Bill 455) that would have limited annual increases to 5-7% stalled in the House Housing Committee in mid-2024 and did not advance into law, leaving Delaware in the large majority of states with no statutory ceiling on rent increases.
For month-to-month tenants, a landlord who wishes to raise rent or alter any other lease term must deliver at least 60 days' written notice, with the notice period running from the first day of the month following actual delivery (25 Del. C. § 5106). The same 60-day window applies when a fixed-term lease is approaching renewal and the landlord intends to modify its terms, including the rent amount (§ 5107). Tenants who receive a rent-increase notice on a month-to-month tenancy may terminate without penalty by giving proper written notice within the response window. Because there is no cap on the size of an increase, tenants in high-demand markets along the I-95 corridor should pay close attention to lease renewal notices and calendar the 60-day clock carefully.
Before a landlord can file for summary possession in a Delaware Justice of the Peace Court, the Code requires written notice tailored to the reason for termination. For nonpayment of rent, the landlord must serve a written notice giving the tenant a minimum of 5 days to pay the full amount due or vacate (25 Del. C. § 5502). If the tenant pays all rent owed before the landlord files a court complaint, the landlord cannot continue the action. For lease violations other than nonpayment -- such as unauthorized occupants or property damage -- the landlord must issue a 7-day notice to remedy, giving the tenant an opportunity to cure before legal proceedings begin (§ 5513). Illegal activity, including felonies or Class A misdemeanors on the premises, requires no advance notice and allows immediate filing.
Delaware law explicitly prohibits self-help eviction. A landlord who changes locks, removes doors or windows, shuts off utilities, or removes a tenant's belongings without a court order exposes themselves to civil liability including damages and attorney fees. The formal eviction process proceeds through the Justice of the Peace Court, with a hearing typically scheduled within a few weeks of filing. Landlords who choose not to renew a lease at its expiration must give at least 60 days' written notice before the end of the term. Beginning in 2025, Delaware further tightened the grounds for eviction by effectively requiring a valid legal cause -- such as nonpayment, a documented lease violation, or non-renewal -- before proceedings can be initiated, strengthening protections against arbitrary removal.
Delaware's Residential Landlord-Tenant Code gives tenants several substantive protections beyond the deposit and eviction rules. The implied warranty of habitability under 25 Del. C. § 5305 requires landlords to maintain rental units in compliance with applicable building and housing codes, keep electrical, plumbing, heating, and hot-water systems in working order, and ensure the unit is free of lead-based paint hazards. If a landlord fails to make a necessary repair after written notice, § 5307 gives the tenant the right to hire a professional and deduct repair costs from rent up to $400 or one-half of one month's rent, whichever is less. When a landlord fails to provide an essential service -- heat, hot water, electricity -- for 48 hours or more after notice, § 5308 allows the tenant to terminate the lease immediately or withhold two-thirds of the daily rent for each day the service remains unavailable.
Retaliation by a landlord is presumed unlawful under § 5516 when any adverse action -- including eviction, rent increases, or reduction of services -- occurs within 90 days of the tenant filing a complaint about habitability, reporting code violations, or organizing with other tenants. A tenant who proves retaliation can recover triple the monthly rent or triple actual damages, plus court costs. Delaware also added a source-of-income protection effective January 1, 2026 (SB 293), prohibiting landlords from refusing to rent to applicants based on their use of housing vouchers or other lawful assistance. Landlords are additionally required to disclose bed bug infestation history before a new tenancy begins under § 5317, and they must give written receipts for any cash rent payments.

Delaware FAQ
For leases of one year or more, Delaware landlords may not collect more than one month's rent as a security deposit under 25 Del. C. § 5514. On month-to-month tenancies, a higher deposit may be collected during the first year, but once the tenancy has run a full year the landlord must credit back any amount held above one month's rent. A separate pet deposit of up to one month's rent is permitted in addition to the standard deposit.
Delaware landlords must return the security deposit within 20 days after the rental agreement ends. Along with any refund, the landlord must provide an itemized written list of deductions with estimated repair costs for each item. Failing to meet this 20-day deadline entitles the tenant to double the amount wrongfully withheld.
No. Delaware has no statewide rent control or rent stabilization law, and no city or county in the state currently has a local ordinance capping rent increases. Landlords may raise rent by any amount, but must give at least 60 days written notice before a rent increase takes effect on a month-to-month tenancy.
Under 25 Del. C. § 5502, a landlord must first serve a written notice giving the tenant at least 5 days to pay all overdue rent or vacate. If the tenant pays the full amount owed before the landlord files a court complaint, the landlord cannot proceed with the eviction. Only after the 5-day period expires unpaid can the landlord file for summary possession in the Justice of the Peace Court.
No. Self-help eviction tactics such as changing locks, removing doors or windows, or cutting off utilities are explicitly prohibited under Delaware law. A landlord who uses these methods can face civil liability for damages and attorney fees. The only legal path to removing a tenant is through the court-supervised summary possession process.
After giving the landlord proper written notice, a Delaware tenant can hire their own contractor and deduct the cost from rent, up to $400 or one-half of one month's rent (whichever is less), under § 5307. If the landlord fails to supply an essential service like heat or hot water for 48 hours or more after notice, the tenant may also terminate the lease immediately or withhold two-thirds of the daily rent for each day the service is unavailable under § 5308.
