A. Any and all amounts of maximum rent and ceiling rent determined in accordance with this chapter shall be deemed to have been predicated upon the continuation by the owner of the same services, amenities, conveniences and facilities in the complex and each apartment therein as the owner provided, without further compensation, under the lease or rental agreement in effect on and as of January 21, 1976. The foregoing shall not be deemed to have been breached by a failure or breakdown, provided that the owner uses due diligence and dispatch and good faith in repairing or remedying the same.
B. Upon the breach of the owner's obligation as set forth in Subsection A hereof, any tenant affected, either for himself or on behalf of the class of all tenants similarly affected, may petition the Rent Control Board for an appropriate reduction in rents. The Rent Control Board, after hearing testimony at a public hearing, shall enter a finding determining whether there shall be a reduction in the ceiling and maximum rents for the complex so affected, which finding shall include such reduction in the rental value as shall be determined by the Board's sole discretion and the effective date thereof.
