Sawyer contends that the Notice to Quit and the Summary Process action were in retaliation for his reporting suspected violations of the Sanitary Code, Building Code and Zoning Law to Watertown officials. The apartment was inspected on May 7, 1993 by the Watertown Board of Health, and the inspector found several violations of the State Sanitary Code and stated that “one or more of the . . . violations constitutes a condition which may endanger or naturally impair the health or safety, and well-being of the occupant.” Later on May 7, 1993, when Demos called Sawyer to inquire about the May rent payment, and Sawyer told Demos that the apartment had been inspected and that he was withholding his rent pending repair of the violations, Demos immediately served Sawyer with a Notice to Quit. It was not established, however, that the eviction was caused by defendant’s complaints to the authorities, or by his announced intention to withhold payment of rent. Accordingly, the Court finds that a retaliatory eviction in violation of G.L.c. 186 §18 has not been proven.
