Should states regulate how often community owners can increase lot rents for manufactured homeowners?

The Delaware Department of Justice recently issued a letter warning manufactured home community owners to limit rent hikes to once annually. This directive comes after officials received multiple complaints from residents regarding recent rental increases.

Why it matters

The guidance ensures that community owners determine rent adjustments using either the Consumer Price Index or market rent value, but not both. Adherence to these regulations is intended to provide clearer cost stability for the state's thousands of manufactured home residents.

Delaware is home to over 20,000 households living in approximately 170 manufactured housing communities. Roughly 1 in 16 households across the state reside in these manufactured home settings.

The players

Delaware Department of Justice

This state agency acts as the primary authority overseeing the legal compliance of manufactured housing communities in Delaware.

The details

Owners are now required to choose between the Consumer Price Index for the Philadelphia-Camden-Wilmington region or the market rent value when calculating increases. Those who have raised rents more than once in the same year are expected to take immediate corrective action or face potential enforcement from the Department of Justice.

Culture Shift

This move reflects a growing societal push to protect affordable housing segments from aggressive market-driven price hikes. By anchoring rent hikes to the Consumer Price Index for All Urban Consumers, the state is prioritizing predictable cost structures over unchecked market speculation.

Residents of manufactured homes should verify that their community owners are not raising rents more than once per year. If a landlord violates this rule or uses both index-based and market-based metrics to increase costs, tenants are encouraged to report these discrepancies to state authorities.

The takeaway

Renters in manufactured housing communities now have clearer legal protections against multiple rent increases within a single calendar year. Residents should keep records of all communication regarding rent adjustments to ensure compliance with these state-mandated guidelines.
