(4) A landlord may seek to recover possession of a housing accommodation which has already been converted to the condominium or cooperative form of ownership for just cause other than a condominium or cooperative conversion eviction. The landlord must allege such just cause as part of the notice of termination of tenancy given to the tenant and as part of the summary process summons and complaint. The landlord shall give notice of the commencement of such summary process action to the OHS at the same time the action is entered in court, together with a copy of the notice of termination of tenancy and summary process complaint. The landlord must prove such “just cause” and rebut the presumption of condominium or cooperative conversion as part of his or her burden of recovering possession. The provisions of this Subsection shall apply only where the tenant was in occupancy at the time of conversion of the housing accommodation to the condominium or cooperative form of ownership.
(G) Penalties for violation. Any person who violates a provision of this Section, which is promulgated pursuant to St. 1983, c. 527, shall be punished by a fine of not less than $300 and, if applicable, by seeking to restrain a violation of this Section by injunction. Each violation, per day, of any provision shall constitute a separate offense. Each unit converted in violation of this act constitutes a separate offense. Fines may be issued pursuant to the noncriminal disposition process of M.G.L. Chapter 40, Section 21D, and may also be enforced according to M.G.L. Chapter 40U.
