Are You Wanting To Build A Two-Family Duplex?
Do you know that the time will come when your elderly parents will be leaving their own home in order to live with you? Or, it might be that you want a second small residence to rent out, or to have ready, just in case your adult children ever need to come home to live, even for a short time.
No matter the reason that you are wanting a two-family duplex, perhaps you have your heart set on a specific floor plan that is different from most duplexes.
