by Wilmington, Delaware – Delaware renters will face new rules regarding rent increases in 2025, providing greater predictability and protection for tenants while balancing landlords’ rights to adjust rental rates. Historically, the state lacked traditional rent control, but recent legislation introduces important limits on annual rent hikes, particularly during lease renewals.
Rent Increase Caps Under House Bill 455
House Bill 455 establishes a cap on rent increases for most residential properties during lease renewals. Landlords can raise rent by a maximum of 5 percent per year based on the previous rent, unless the 36-month average annual increase in the Consumer Price Index for All Urban Consumers (CPI-U) exceeds 5 percent. In such cases, the cap may increase to 7 percent to account for inflationary pressures.
The law is framed as a ten-year statewide pilot program aimed at addressing affordable housing concerns, ensuring that rent hikes are controlled and predictable, particularly for tenants renewing existing leases. For new leases, landlords must comply with the renewal cap if the prior rent equals or exceeds the federally established Fair Market Rent. Otherwise, adjustments are made according to market rates within the new legal limits.
Written Notice Requirements
Delaware law requires landlords to provide written notice at least 60 days before a rent increase takes effect for most residential properties. This notice period applies to standard leases and month-to-month tenancies, giving tenants time to prepare financially, explore other housing options, or negotiate with their landlord.
According to The Huron Insider, An exception applies to manufactured home communities, where landlords must provide 90 days’ written notice. In some instances, landlords must formally justify increases that substantially exceed inflation or market rates, enhancing transparency and tenant protection. Failure to comply with notice requirements renders a rent increase legally invalid.
Protections Against Discrimination and Retaliation
Under Delaware law, rent increases cannot be discriminatory or retaliatory. Landlords may not raise rent based on race, sex, national origin, familial status, disability, or other federally and state-protected characteristics.
Similarly, increases cannot be retaliatory, such as targeting tenants who report housing code violations, join tenant associations, or engage in other lawful activities. Tenants who believe a rent hike is unlawful have the right to contest it within 45 days, often through formal mediation or legal channels.
Rent Increases During Lease Terms
Rent increases are generally not allowed during a fixed-term lease unless the lease explicitly permits adjustments. Typically, rent may only rise upon lease renewal or when a lease transitions from fixed-term to month-to-month.
For tenants in manufactured homes, only one increase per year is permitted. Any requested increase above the rate of inflation must be documented by the landlord, adding an extra layer of accountability.
