Forest Park GA - Clayton County Zoning

[Josh Louis]

Was wondering if anyone in/around Atlanta GA was familiar with Clayton County. I'm looking at the Forest Park area and on the GIS zoning map there appears to be no specific zone code... most of that entire area is just labeled as "R". I understand that means residential but I'm looking to possibly add an ADU to a property and on the county site it states that properties zoned AG, ER, and RS-180 are ok to have ADUs.

Naturally, my search for clarity would have ended there but I noticed there was no explicit notation for properties zoned as just  "R"... see link to zoning districts and see attached image of GIS map legend:

So, my question now is, is there no reference to what "R" is or am I just not seeing it? If there is no specific reference then does that mean anything labeled "R" takes on the same codes as anything else labeled "R" (R-180 for example)? Or is it the opposite (which would not be ideal) it just means residential and nothing can be added or modified without some-sort of expressed county approval... :(

I called the office but no one picked up. Left my contact info but I don't expect a call back anytime soon. I'm going to keep looking but just thought I'd ask.

Thanks

Try searching for Forest Park zoning - sometimes zoning is regulated by the city, not the county.  I've copied a couple links here for you.
