it's a tradesman exit. they call it a tradesman, but it's a required exit from the rear yard and if you are going to penetrate that with an air intake, you have to have a fire smoke damper there, which is what the fire department would have caught. they also have a penetration from the restaurant into the entrance into the building. which would have required a fire smoke damper and more or a more important issue, a fundamental issue, they failed to get a permit for change in use from the previous use to a less than 50 restaurant >> thank you. >> and the last thing is what is more important and this is a housing issue, these are the windows. here we show one window, there are five windows in this light well and where they have drawn this shaft is directly in front of a bedroom window. directly in front of a dining window, which is a significant housing complaint in my discussions with rose marie the chief housing official this morning, they said this duct could never be in the shaft. no way, no how. >> thank
