Charlotte follows local ordinances layered on top of North Carolina state ADU law. Typical restrictions cover maximum size (often 800–1,200 sqft), height (16–25 feet), side setbacks (4 feet minimum in most jurisdictions), parking (often waived near transit), and owner-occupancy. Buildability™ reads Charlotte's specific code against your exact lot.
Why this matters
ADU permits in Charlotte typically take 60–180 days and cost $15,000–$50,000+ in soft and hard costs combined. Before paying a designer or contractor, verify your lot's eligibility — setbacks, existing FAR, utility access, and local overlays can block a build that looks fine on paper.
