Wilmington's Rent Cap Fight: What the Referendum Means for Delaware Landlords

As of October 23, 2026, Wilmington does not have a newly enacted general rent cap. But the effort to put rent stabilization before voters is still a live issue for property owners with units inside city limits. The proposal has a potential route forward through a charter-amendment petition, and the ordinance that failed in City Council offers a useful, though not guaranteed, preview of what some of the rules could look like.

For landlords, the practical approach is to distinguish what is law now from what could change, keep documentation current, and watch for formal updates on the petition process.

A city-level proposal, not a statewide rent cap

In January 2026, Wilmington City Council members Shané Darby, Coby Owens and Christian Willauer launched an affordability agenda that made rent stabilization a top priority. Darby’s rent-stabilization ordinance failed in City Council in 2025. Advocates are now pursuing a public referendum rather than simply returning the same proposal to council.

The petition effort is seeking paper signatures, with organizers targeting about 6,000 to leave room for verification. The legal threshold is lower: under 22 Del. C. § 811, a petition to elect a charter commission must be signed by at least 10% of a city’s qualified voters. In Wilmington, that has been reported as more than 3,600 signatures.

That threshold does not put a rent cap directly on the ballot. If the petition is filed and verified, voters elect a seven-member charter commission. The commission can hold public hearings, develop a proposed charter amendment and arrange for it to be submitted at a referendum. Under § 813, a majority of voters who vote on the question must approve it. The General Assembly then has a 30-day period, after the required filings and while in session, to negate the amendment by a two-thirds vote in each chamber.

The distinction matters: a petition campaign, a verified petition, a commission election and a referendum are separate steps. Until a measure completes the required process and takes effect, landlords should not treat a proposed cap as current law.

What the 2025 proposal could tell landlords

The failed Sub. 1 to Ord. 25-016 is a useful reference point, but it should not be mistaken for final referendum language. A future charter amendment could differ. The 2025 text proposed capping an annual rent increase at the lower of 3% or the 12-month average change in the Philadelphia-Camden-Wilmington CPI-U. It also limited increases to once in any 12-month period and required written notice consistent with Delaware’s 60-day notice rule.

The draft included exemptions for:

• Public housing and units receiving state or federal subsidies

• Owner-occupied buildings with three or fewer units

• Hotels and other transient accommodations

• Certain nonprofit, institutional and religious housing

• Single cooperative units and institution-controlled student housing

• The initial rent charged to a new tenant

• New buildings during their first 10 years

It also included a process for seeking an exception to the cap based on a reasonable return on investment. Factors included changes in property taxes, insurance, maintenance and operating expenses, qualifying capital improvements, occupancy or services, and property deterioration. The draft barred an exception when a unit did not meet the implied warranty of habitability or when the owner had held it for less than a year.

Other proposed provisions addressed refunds or credits for unauthorized increases, a tenant’s right to bring a claim, and possible consequences for a landlord’s rental business license. These details could have significant operational effects, but they are features of the failed ordinance, not rules landlords should assume will appear unchanged in a referendum version.

Owners should also look closely at which exemptions might apply across their portfolio. A building’s ownership structure, subsidy status, unit type and age could matter if similar language is proposed again.

What the statewide picture means

The 2026 legislative session did not produce a general rent cap for Delaware residential rentals. Senate Bill 235, signed July 23, 2026, deals specifically with rent-increase calculations in manufactured-home communities. It repealed a sunset date for those calculations; it did not create a statewide cap for standard apartments or houses.

That means Wilmington landlords should track the local charter effort separately from statewide law. Owners with properties in other Delaware municipalities should not assume that a Wilmington proposal applies to their units.

For today’s rent-increase procedures, review the existing rules and lease terms. Advanced Realty Solutions’ guide to Delaware rent increases and the 60-day notice requirement provides a practical overview. As always, confirm the requirements for a specific situation with qualified legal counsel.

Practical steps landlords can take now

Whether or not a referendum advances, good records and consistent processes help protect your business. Consider these steps:

1. Keep rent notices timely and documented. Maintain a calendar for lease expirations and records showing when written notices were delivered. Continue following the current 60-day notice requirement.

2. Avoid multiple increases inside a 12-month period. The 2025 proposal included a one-increase-per-12-months rule. Keeping a clear history of each unit’s rent changes makes it easier to assess compliance if similar language returns.

3. Build an expense file for every property. Save property-tax bills, insurance renewals, invoices for repairs and maintenance, operating-cost records and documentation for capital improvements. These records could help explain the business rationale for rent decisions and would be relevant if an exception process resembling the 2025 draft were proposed.

4. Check potential exemptions unit by unit. Don’t assume that every property or apartment would be treated the same way. Record subsidy status, owner occupancy, number of units, building completion date and any institutional or student-housing connection.

5. Monitor official milestones. Watch for updates about petition filing and verification, a charter-commission election, commission hearings, proposed amendment language and a referendum date. The Delaware statute and Wilmington City Council’s website are useful places to confirm process information.

Rental assistance is a separate, and practical, development

Wilmington City Council also unanimously passed a Security Deposit and First Month’s Rent Assistance Pilot Program in early October. Administered by the city’s Department of Real Estate and Housing, the pilot offers up to $2,000 for eligible low-income renters: up to $1,000 toward a security deposit and $1,000 toward first month’s rent. Applicants must show they can cover one month of rent themselves, and assistance is limited to once per 24-month period. The reported estimated program cost ranges from $82,500 at the lowest utilization to about $2.3 million at the highest.

This assistance is not rent stabilization. For landlords, though, help with move-in costs may support leasing and reduce barriers for qualified applicants. Treat it as a possible rent-collection and occupancy resource: learn the program’s application and payment procedures, communicate clearly with applicants and confirm any requirements directly with the city. Wilmington has also discussed an eviction-prevention program and pre-rental inspections; these are separate items to monitor rather than provisions of the rent-cap proposal.

The takeaway for Wilmington property owners

The referendum effort makes rent stabilization a real policy issue, but it has not made a cap effective. The most useful response is preparation, not speculation: follow the petition and charter timeline, document operating expenses, keep notice practices disciplined and understand which units could fit proposed exemptions.
