Several thoughts and some questions here, if anyone can help! My building is mostly all cinder block! Can we individually just go ahead and install? How will that impede sprinkler installations? Did they not have smoke alarms in the building? Were the elevators working? How do people get out in such a situation? So alarming for older women!!!A tax credit would certainly help a lot! Speaking of which, haven't received my Hawaii tax refund yet! Is there a back log?
