Atlanta Zoning Question

[Joshua Feit]

Hello BP!

I am chasing an off-market deal, but have run into a snag. As the property sits, it is a purpose-built duplex (separately metered) built in 2004. It also has a large detatched garage with a second floor 1BR unit (separately metered as well).

I have an offer in right now and am waiting to hear back.

MY QUESTION:

I was poking around on an Atlanta zoning map, and I noticed the property is zoned r4a -- single family residential. Does that kill this deal? Or should I try to get zoning changed? Or nonconforming use confirmation?

A structure built in 2004 undoubtedly was permitted, right? And if so, wouldn't the inspectors have caught this?

So, what to do??? Thank you for your insights!
