Zoning for a duplex in Philadelphia

[Matthew Tierney]

What up BP

I’m looking at duplexes in Philly and I’ve heard there is a lot that are illegal. I see a lot that were typical Philly rowhomes that were converted into duplexes and then there are more small apartment style that look more legit. My portfolio is a mix of private and section 8 renters in single family homes so I guess I’m looking for some insight before I buy a duplex and then find out it can only be used as a single family home.
