Finished a basement in Philly before?

[Marioly Toles]

Hi BP community! I'm in the early phase of finishing a basement in my duplex. I househack and I'm used to some dyi, so I'll probably do a good amount of it myself to save some money and get some experience. Right now, it's just cement floors and walls, has a toilet and laundry installed. I'd like to turn it into an Air BNB studio. I'm not aiming for anything fancy, just a basic, safe and comfortable space.

Has anyone finished a basement in the Philly area before? I'd appreciate any advice on some things to watch out for in terms of codes, cost and must-haves.  I'm particularly concerned with things like what's acceptable for egress, and when is moving a breaker box worth it. Thanks in advance!
