SEC. 37.9B. TENANT RIGHTS IN EVICTIONS UNDER SECTION 37.9(a)(8).
(a) Any rental unit which a tenant vacates after receiving a notice to quit based on Section 37.9(a)(8), and which is subsequently no longer occupied as a principal residence by the landlord or the landlord’s grandparent, parent, child, grandchild, brother, sister, or the landlord’s spouse, or the spouses of such relations must, if offered for rent during the five-year period following service of the notice to quit under Section 37.9(a)(8), be rented in good faith at a rent not greater than that which would have been the rent had the tenant who had been required to vacate remained in continuous occupancy and the rental unit remained subject to this Chapter 37. If it is asserted that a rent increase could have taken place during the occupancy of the rental unit by the landlord if the rental unit had been subjected to this Chapter, the landlord shall bear the burden of proving that the rent could have been legally increased during the period. If it is asserted that the increase is based in whole or in part upon any grounds other than that set forth in Section 37.3(a)(1), the landlord must petition the Rent Board pursuant to the procedures of this Chapter. Displaced tenants shall be entitled to participate in and present evidence at any hearing held on such a petition. Tenants displaced pursuant to Section 37.9(a)(8) shall make all reasonable efforts to keep the Rent Board apprised of their current address. The Rent Board shall provide notice of any proceedings before the Rent Board to the displaced tenant at the last address provided by the tenant. No increase shall be allowed on account of any expense incurred in connection with the displacement of the tenant.
