BATH — The City Council is moving toward adopting strict new rules for vacant buildings in the city. “We’ve had a number of complaints about vacant buildings, and these are buildings where no one is living in the house,” City Manager Peter Owen said this month. The council gave initial support to the ordinance during a meeting July 11 and is scheduled to take a final vote Wednesday. Even if the buildings are owned and the owners are paying taxes, the city lacks an ordinance to deal with unoccupied buildings unless they pose a hazard.
