Delaware Short-Term Rental Regulations (2026)

Delaware short-term rental compliance has two distinct layers. State law governs the short-term rental lodging tax, while cities, towns, and counties may impose their own licensing, zoning, inspection, occupancy, and local tax requirements.

The exact rules depend on the property address. A Rehoboth Beach vacation rental, a Lewes rental, a Dover primary residence, and a property in unincorporated New Castle County do not follow the same local process. Confirm the jurisdiction before advertising or accepting reservations.

Quick answer: what Delaware hosts need to check

Determine whether the stay meets Delaware's state lodging-tax definition.
Confirm who must collect and remit the 4.5% state short-term rental lodging tax.
Check local zoning before treating a dwelling as a short-term rental.
Obtain every required city, town, or county rental license or registration.
Confirm local inspection, occupancy, parking, contact-person, and advertising rules.
Verify municipal rental or lodging taxes separately from the state tax.
Review insurance coverage with an insurer because a personal homeowners policy may not cover rental activity.

Delaware's state short-term rental lodging tax

State definition

For the state tax, Delaware Code defines a short-term rental as a house, duplex, multi-plex, apartment, condominium, houseboat, trailer, or other residential dwelling unit where a tourist or transient guest rents sleeping or living accommodations for no more than 31 consecutive nights.

The definition excludes hotels, motels, tourist homes, assembly spaces, educational dormitories, licensed healthcare facilities, campground accommodations, and overnight camps. It also excludes a rental arranged directly by the owner on a casual and isolated basis when the rent is substantially below market and the property is rented for no more than 10 nights in aggregate during the calendar year.

These are state tax definitions. A municipality may use a different duration or property definition for its own licensing and zoning rules.

Tax rate and effective date

Delaware imposes a 4.5% short-term rental lodging tax on rent for qualifying stays. The tax applies to short-term rental agreements entered into on or after January 1, 2025.

Under Delaware Code, taxable rent does not include municipal taxes, linen rental fees, cleaning fees, insurance fees, security deposits, other add-on fees not usually considered part of rent, or money received from a month-to-month holdover lease.

Who collects and remits the state tax

Responsibility depends on how the reservation is booked:

Third-party booking: If an owner uses a third-party rental listing company to book the stay, the licensed third-party accommodations intermediary is responsible for collecting and remitting the Delaware short-term rental lodging tax.
Direct booking: An owner who books qualifying short-term rentals without a third-party intermediary must collect and remit the tax and obtain a Delaware accommodations-intermediary business license. The Division of Revenue states that this license costs $25.

The tax collected for each month must be filed and paid through Delaware's taxpayer portal no later than the fifteenth day of the following month. Owners should confirm what a platform collected and retain booking, rent, fee, cancellation, and tax records that support each filing.

Official state guidance is available in Delaware Code Title 30, Chapter 62 and the Delaware Division of Revenue short-term rental FAQs.

Local Delaware short-term rental requirements

Delaware's state tax chapter does not create one statewide operational permit for every host. Local requirements must be checked independently. The following examples apply only within the named jurisdiction.

Rehoboth Beach

Rehoboth Beach requires a residential rental license. The city's official licensing guidance directs owners to confirm that the property is appropriately zoned and complies with local building and safety codes.

Among the city's stated requirements:

Provide ownership, identification, property, owner, and managing-agent information during the application process.
Designate a local contact who can be reached 24 hours a day when necessary to address concerns.
Complete and submit an annual self-inspection addressing life safety, property maintenance, and city-code requirements.
Post the rental license, local contact information, and required notices inside the rental.
Limit overnight occupancy to two persons per bedroom plus two additional persons. Children age six or younger are excluded from the occupant count.
Renew the residential rental license annually. The city accepts renewals up to 60 days before the current license expires.

Rehoboth Beach also states that property owners who rent their homes pay a 7% local rental tax. The city mails the annual gross-rental-tax form on December 1, and payment is due February 15. This local tax is separate from Delaware's 4.5% state short-term rental lodging tax.

Verify the process on the city's Residential Rental License and Lodging and Rental Taxes pages.

Lewes

Lewes defines a short-term residential rental as all or part of a residential dwelling unit rented to one party for 30 consecutive days or less. The city requires the owner to obtain a valid rental license for the January-to-December license year.

Lewes also requires short-term rental owners to:

Remit the prior year's gross receipts rental tax.
Comply with building, health, fire, safety, zoning, and occupancy requirements.
Designate a local contact who is available 24 hours a day and can physically respond within two hours if requested by the city.
Include the city-issued rental identification number in every advertisement.
Maintain booking dates and rental-income records and provide them with the annual gross receipts rental tax remittance.
Provide renters with required local-contact, parking, emergency, trash, and evacuation information.

Review the current requirements on the official Lewes Short-Term Residential Rentals page.

Dover

Dover's Short Term Rental Use ordinance applies to compensation-based occupancy of all or part of a residential one-family dwelling for less than 30 days. Rentals lasting 30 days or more fall under Dover's other rental-dwelling provisions.

Key Dover requirements include:

The use must be in a one-family dwelling where that dwelling type is allowed by right and does not require a variance or conditional-use approval.
The owner must obtain an annual Short Term Rental Use license.
The city requires a code-enforcement inspection before the first license is issued. Renewal inspections may be required.
The license must be renewed no later than January 31 for continued operation.
The owner must be a City of Dover resident and may offer only the owner's primary residence as a short-term rental.
Guests age 12 and older may not exceed two per bedroom, and total occupancy may not exceed 12 people of all ages.
Special events are prohibited unless the city issues a special-event permit.
Three nuisance or illegal-activity citations within a consecutive 12-month period can result in license suspension.

The adopted ordinance does not support a claim that Dover limits operation to 30 total rental days per calendar year. The relevant duration rule defines each short-term stay as less than 30 days.

Review the full City of Dover Ordinance 2020-05 and confirm current fees and procedures with Dover Code Enforcement before listing.

Wilmington

Wilmington City Council's official pending-legislation record lists Ordinance 24-068, which would establish short-term residential rental regulations, as pending. It received first and second readings on November 21, 2024 and was referred to the Community Development and Urban Planning Committee.

Because the proposal remains pending on the official Council page, hosts should not treat proposed permit, ownership, cap, insurance, inspection, or tax provisions as enacted law. Confirm current residential rental licensing, registration, inspection, and zoning requirements directly with Wilmington Licenses and Inspections before operating.

Check the latest status on the Wilmington City Council Pending Legislation page.

Unincorporated New Castle County

New Castle County's rental property registration program applies to residential rental properties in unincorporated New Castle County. Registration is free, and owners must update their registration information by May 1 of each odd-numbered year.

The county also requires property owners to provide tenants with its Tenants Rights Guide. Confirm whether the property is in unincorporated county jurisdiction or inside a municipality with separate requirements before relying on the county program.

See the official New Castle County Rental Property Registration page.

Unincorporated Sussex County

Sussex County considered a proposed 3% lodging tax on short-term rentals in unincorporated areas, but County Council denied the proposal by a 3-2 vote on December 10, 2024. Do not add that proposed county tax to a short-term rental calculation as though it were enacted.

This does not eliminate Delaware's 4.5% state tax or taxes imposed by incorporated cities and towns. Verify the property's municipal boundaries and current local tax rules.

The decision appears in the official Sussex County Council meeting minutes.

Step-by-step Delaware compliance checklist

Confirm the jurisdiction. Determine whether the property is inside an incorporated city or town or in an unincorporated county area.
Check zoning first. Ask the local planning or zoning office whether short-term rental use is allowed for the property and dwelling type.
Identify required licenses. Apply for every local rental, business, or short-term rental license before accepting reservations.
Confirm the state tax workflow. Determine whether a licensed third-party intermediary or the owner is responsible for collection and remittance.
Check local taxes. Do not infer a city or county tax from a neighboring jurisdiction.
Complete inspections and safety steps. Follow the local program's inspection, self-certification, occupancy, alarm, egress, and posting requirements.
Set up local response coverage. Where required, designate a local contact who meets the jurisdiction's availability and response-time rules.
Review advertising requirements. Include a permit or rental identification number when local rules require it.
Document compliance. Keep licenses, inspection records, tax filings, booking records, local-contact details, and guest notices organized.
Recheck before renewal. Local ordinances, forms, fees, and deadlines can change.

Common compliance mistakes

Using 30 nights as Delaware's state tax threshold when the current state definition is no more than 31 consecutive nights.
Assuming a booking platform resolves every state and local tax obligation.
Confusing Dover's less-than-30-day stay definition with a 30-total-days-per-year operating cap.
Treating Wilmington's pending short-term rental ordinance as enacted law.
Applying the denied Sussex County 3% short-term rental tax proposal as a current tax.
Applying an unincorporated county registration rule to a property inside a municipality.
Listing before confirming zoning, licensing, inspection, occupancy, and local-contact requirements.

Where to verify Delaware short-term rental rules

Bottom line

Delaware hosts must combine the state's lodging-tax rules with the requirements of the property's exact local jurisdiction. The state tax rate is 4.5% for qualifying rentals of no more than 31 consecutive nights, but local licensing, zoning, inspection, occupancy, contact-person, advertising, and tax rules vary.

Before listing, verify the state tax process with the Delaware Division of Revenue and confirm local requirements with the relevant city, town, or county. For a property-specific legal interpretation, consult qualified Delaware counsel or the responsible government office.
