Just an update. I passed by 1530 3rd St NW. I have noticed work is being done. There appears to be a permit on the door. Thing is, DCRA's PIVS has no permits listed for this year and the owner is still dead. But for a dead guy he's throwing up framing pretty quickly.
Since we're in a hot-hot prosecco-bubbly real estate market I predict that this will sell quickly for an ungodly amount of money regardless if the right permits or any inspections occur.
