Prince George's County multifamily zoning?

[Tim Burke]

Hi BP People!

I live in Washington DC, and I'd like to turn my current condo into a rental and start house hacking by buying a multifamily property. Unfortunately, there are so few of them available and the competition is fierce for them. I'm considering the idea of building a duplex, likely somewhere just outside of the city bounds. In DC and in Montgomery County, it's easy enough to look up the zoning maps to see if an address has the proper zoning for building a multifamily dwelling, but I'm having no luck finding this information for Prince George's county. Does anyone have any insight on finding zoning info/maps online? Maybe it's just really well hidden. 

Also, anyone else who has gone down the path of building a duplex, in or out of this area, I'd love to hear about your experiences.
