Do I need a permit for addition or structural alteration in Chapel Hill?
Yes. In North Carolina, addition or structural alteration generally requires a permit, and Chapel Hill is no exception.
An addition or structural alteration always requires a permit and cannot use the NCGS 160D-1110 minor-work exemption because it involves structural work. Expansions may trigger zoning, setback, or stormwater review in addition to the building permit; confirm requirements with your local department early. Chapel Hill Building and Development Services runs both a zoning review (setback, height, impervious surface, land disturbance) and a building review for any work with structural components. Adding or redesigning structure is excluded from the NC General Statute 160D-1110 cost exemption. Chapel Hill has among the most restrictive development regulations in the Triangle. Resource Conservation District buffers, Jordan riparian buffers, tree protection under LUMO 5.7, and impervious surface area ratio limits can all apply, and disturbing more than 20,000 square feet also requires an Orange County Erosion and Sediment Control Permit and Land Disturbance Permit before work begins. In the Historic District or the Northside and Pine Knolls Neighborhood Conservation Districts, additional review and mailed notices can be required. Orange County's own permitting office is the Orange County Planning and Inspections office, reachable on 919-245-2575 at https://www.orangecountync.gov/792/Planning-Inspections. Its online permit portal is https://centralpermits.orangecountync.gov/EnerGov_Prod/SelfService#/home. It issues permits for the unincorporated county. If your city does not run its own building department, this is the office that will handle the job, and that is more common in North Carolina than most states: the county is often the building authority even inside city limits, with the city handling only zoning. An addition means a full plan review, so confirm submittal requirements and current review times before you commission drawings.
