Enhances transparency concerning properties claiming exemption from rent control.

This bill requires property owners of new apartment buildings to clearly disclose rent control exemption status to tenants and maintain public records. It limits rent control exemptions to 30 years after construction completion (or the mortgage amortization period, whichever is shorter), and mandates owners to provide written statements with expiration dates before leasing. Owners must submit documentation - including mortgage records and certificate of occupancy - to municipalities and the state's public registry, which will be searchable online. Tenants in exempt properties will receive clear lease notices about the exemption's end date, and owners face penalties for failing to comply. The law applies specifically to newly built multiple-dwelling properties claiming exemption under existing rent control ordinances.
