Basement ADU in Flood Zone
I'm looking at purchasing a Duplex and turning the basement into a 1-2 bedroom, 1 bath unit. It already has a kitchen area and bathroom built out, but unfortunately it never passed coding for a legal 3rd unit. (I think this was mostly due to egress and possibly being in a flood zone) Does anyone have any experience with turning a basement into an ADU? What kind of costs am I looking at for adding an egress window and water proofing the basement? Are there any other things I should know or be worried about before taking this on. Thanks!
