REVERE – City Inspectional Services Director Nicholas Catinazzo is urging residents to call City Hall with information about the condition of vacant buildings across the city.City inspectors periodically check on vacant buildings and bill their owners for administrative costs ranging from $500 to $3,000. Only $9,250 out of $40,500 in fines has been collected, but Catinazzo said the fines are meant to motivate owners to fix up their property or replace it.”You’re better off selling your property, having it demolished, then building something else. The idea is to avoid blight,” Catinazzo said.Two-thirds of the buildings on a list of 45 vacant properties compiled by Catinazzo’s office in 2007 were vacated within the last year. The city took its cue from Wilmington, Del. in adopting the building fine system.”Before the vacant ordinance building passed, the only enforcement tool was outside sanitation code enforcement,” Catinazzo said.A building at 60 Warren St. left vacant a year ago and another on Furness Street were repaired, Catinazzo said, after the city publicized the vacant property list starting last fall.City inspectors ordered Gloria Avila of Randolph to fix up 60 Warren or start tearing it down. A fire damaged the building’s second floor last October and Mayor Thomas Ambrosino ordered inspectors to ensure the building did not pose a threat to public safety.The two-and-a-half story wood frame house has been a sore spot for neighbors and city officials since May 11, 2004 when former resident Albert Hovasse was killed after a welding torch he was using to repair pipes in the house started a fire.The city received assurances on at least one occasion that repairs were planned for 60 Warren and a fire inspector was told workers were in the building days before the most recent fire.He said inspectors sent several letters to owner Gloria Avila of Randolph and fined her after inspections determined 60 Warren was in violation of municipal ordinances governing property maintenance.Inspectors sent a letter to Avila last May 8 and again on Oct. 22 warning her 60 Warren “was dangerous to life or limb.”
