Charlotte allows ADUs in residential zones with reasonable regulations. The city's rapid growth and housing demand have made it increasingly supportive of accessory units as an infill strategy.
Zoning & Size Requirements [1][2][3]
Yes, you can build an ADU in Charlotte. A detached ADU can be up to 1,000 sq ft under current North Carolina and Charlotte zoning rules.
| Allowed Zones | Single-family residential zones |
| Max Size (Detached) | 1,000 heated sq ft, and no more than 50% of the principal dwelling's floor area (whichever is less) when in an accessory structure |
| Max Size (Attached) | 800 sq ft |
| Max Size (JADU) | Not allowed |
| Max Height | No taller than the principal dwelling (the district height cap applies - 35 ft in common N1 districts, up to 45 ft in some) |
| Max Units | 1 ADU per lot |
Setback Requirements [1][2][3]
Charlotte requires a rear setback of about 15 ft for a detached ADU, and no additional parking is required. Owner-occupancy is not required — you can rent it out without living on the property.
| Rear Setback | 15 feet |
| Side Setback | 5 feet |
| Front Setback | 20 feet |
| Parking Required | No additional parking required beyond the principal dwelling; an ADU may not have a separate driveway (exceptions for corner lots or alley access) |
| Owner Occupancy | Not required - Charlotte's UDO (2023) does not impose an owner-occupancy requirement; the ADU and principal dwelling must remain under the same ownership |
| Min Lot Size | 5,000 sq ft |
