I am at a loss for what direction to go toward- I've attempted to hire engineers, contractors, etc. but all say that it should be 'fine' and then back away when told by City inspector that they should 'adopt' permit that was abandoned over a year ago. In addition , the building Dept assures me that despite the jackhammering of concrete and plaster in my 1927 home, their dept. doesn't enforce the lead laws in residential, 'otherwise they couldn't demo ANY houses before 1978!" no kidding
