The bill, P.L.2025, c.85, introduces new definitions and regulations concerning rent increases for covered dwelling sites within manufactured home parks in New Jersey. It defines key terms such as "Commissioner," "covered dwelling site," "landlord," and "tenant," and establishes that landlords cannot increase rent by more than three and a half percent over a 12-month period, with specific provisions for initial rates in new tenancies. Additionally, it outlines penalties for landlords who violate these rent increase limits, including a $1,000 fine per violation and the potential for tenants to recover damages and attorney fees in court.

The bill also clarifies that it does not preempt municipal ordinances that impose stricter rent control measures, provided they do not exceed the three and a half percent limit. It allocates $2,000,000 from the General Fund to the Department of Community Affairs to implement the act and mandates the Commissioner to adopt necessary regulations. The act will take effect immediately, but certain sections will remain inoperative until eight months after enactment, applying to tenancies that commence thereafter.
