DE HB455

Establishes a 10-year rent stabilization program (January 1, 2025 through December 31, 2034) limiting rent increases to 5% annually, or up to 7% if the 36-month Consumer Price Index for All Urban Consumers exceeds 5%.

For new rental agreements, caps rent increases based on Fair Market Rent thresholds, with increases limited to the percentage allowed for renewals or 7% of Fair Market Rent, whichever applies.

Exempts owner-occupied 2-unit structures, income-based rental agreements under federal regulations, and Low-Income Housing Tax Credit units from rent increase limitations.

Requires the Delaware State Housing Authority to annually calculate and publish cost-of-living indices and Fair Market Rents by county, issue rent increase guidance, and compile effectiveness reports through 2034.

Mandates landlords report annual rental unit data to the state beginning January 1, 2026, including rent amounts, vacancy periods, and amenities, with civil penalties up to $150 per violation for non-compliance.
