Harnett County, NC Home Business: Zoning & Home Occupation Permits (2026)

108(A) of the Unified Development Ordinance sets the rules for a customary home occupation run out of a house anywhere in the county's unincorporated zoning jurisdiction. The business can employ no more than one assistant beyond the resident operator, and it may not run mechanical equipment beyond what would normally be used for domestic or professional purposes. The occupation is capped at 50% of the total floor area of any one structure, and the ordinance draws a hard line against using a detached garage, barn, or shed for the business at all.

If the home occupation requires modifications to the dwelling, those changes must satisfy the North Carolina State Building Code, and the county requires 20% of whatever is spent on those improvements to go toward ANSI accessibility compliance. Manufactured homes get an extra requirement: any modification made to accommodate a home occupation must be designed by a structural engineer licensed in North Carolina, not just built by a contractor. These standards were adopted with the county's UDO on October 17, 2011 and last amended June 18, 2012.

Compliance is checked through the Planning Department's zoning review process, and a homeowner who exceeds the floor-space cap, hires a second assistant, or converts a shed into a workshop is out of compliance the moment the county's Planning staff documents it, regardless of whether neighbors complain.
