Questions on R-3 Zoning in Charlotte

[Jerry Mical]

Hi all!

I was doing some research into zoning laws and trying to grasp an understanding of everything. There was a house that is zoned R3 and it is a 4bd 2ba on .87 acres. Based on the "minimum lot area (sq ft)" chart that I am reading here for Charlotte (http://ww.charmeck.org/Plannin...) on Page 12, it appears I could turn this into a duplex as long as the minimum lot size is 16,000 Sq Ft. Based on .87 acres on the lot, I am calculating 30,000+ sq. ft. for the minimum lot size, meaning I would be able to properly convert this into a duplex, right? Also based on that zoning ordinance, it appears I would not be able to convert it into a triplex or a quadplex as those columns were empty in the chart. I am new to this stuff so I am making a few (likely incorrect) assumptions.

Assuming my understanding (and math) is correct and I would be able to convert this 4bd 2ba into a duplex, I would want to turn it into a two unit 2bd/2ba duplex or expand it to 3bd/2ba on at least one side. I feel like I am missing some key points that would not make this plan viable. Most likely, I am misunderstanding the zoning as this is the first time I have done deeper than surface-level research on zoning. Please provide any and all feedback. I look forward to the discussion and learning!

Side note, I thought of as I was about to hit submit - If the 30k minimum sq ft requirement is correctly calculated, could I have a duplex (16k min sq ft.) and add a detached dwelling (10k min sq ft.) also? Or is that not how the zoning works?

Best,

Jerry
