Do I need a permit for addition or structural alteration in City of Jacksonville?

Permit required

Yes. In North Carolina, addition or structural alteration generally requires a permit, and City of Jacksonville 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. An addition adds or redesigns load bearing structure, an express exception to the North Carolina $40,000 exemption, so a permit is required regardless of cost. Plan review runs through E-Plan. An application and the plan review fee go in first, and only then does the city email an invitation to upload the plans, so build that sequence into your schedule. Jacksonville sits on the New River in Onslow County. If any part of the site is in a flood zone or a coastal area, call 910-938-5232 option 2 for flood, CAMA, and zoning before designing, since those approvals can change the foundation and elevation. Onslow County's own permitting office is the Onslow County Planning and Development Department, reachable on 910-455-3661 at https://www.onslowcountync.gov/172/Building. Its online permit portal is https://onslowcountync-energovpub.tylerhost.net/Apps/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. Onslow County is one of the 20 coastal counties covered by the Coastal Area Management Act, so development inside an Area of Environmental Concern needs a CAMA permit on top of the building permit. This follows you into the towns in the county, not just the unincorporated area. An addition enlarges a structure, which is squarely within CAMA's definition of development, so on a near-water lot expect the CAMA permit to gate the building permit. You are probably in an Area of Environmental Concern, and so probably need a CAMA minor permit, if the work is in or on state waters or a marsh or wetland, within 75 feet of the normal high water line along an estuarine shoreline, within 30 feet of the normal water level of designated inland fishing waters, or within 575 feet of the mean high water line of an Outstanding Resource Water. Most homes in a coastal county are not affected. Areas of Environmental Concern cover almost all coastal waters but only about 3 percent of the land, so this bites on waterfront and near-water lots rather than everywhere in the county. If you are nowhere near water, it almost certainly does not apply. CAMA minor permits are issued by a local permit officer, often sitting in the same county or town office as the building permit, so ask about both in the same call. Depending on scope you may need a minor, major or general permit, and the CAMA permit normally has to be in hand before the work starts.
