Who handles permitting in Duplin County?

Towns. Duplin has no countywide zoning; the unincorporated county is unzoned, and the County Planning Department does not keep any town’s zoning information. Each municipality zones its own town limits and ETJ. The County’s building and manufactured-home applications ask for the town’s zoning approval when a site is in or next to a town’s limits or ETJ, then the permit itself is issued by County Building Inspections. That applies in Beulaville, Calypso, Greenevers, Kenansville, Magnolia, Rose Hill, Teachey, Wallace and Warsaw, and in the Duplin parts of Faison, Harrells and Mount Olive.

• Warsaw: the Town’s Code Enforcement/Planning Officer reviews zoning and site plans (910-293-7814, ext. 100).
• Wallace: the Town’s Planning, Zoning and Community Development Department keeps its zoning ordinance and map, at 120 Municipal Drive.
• Rose Hill: Town Hall issues the zoning permit after a $25 application is reviewed, and the County will not issue the building permit until that is done (910-289-3159).
• Kenansville: the zoning application goes to Town Hall with a site plan, proof of ownership or lease and a $50 fee, paid in cash or by check (910-296-0369).
• Magnolia: the Town posts a zoning application and allows 5 business days for a reply (910-289-3205).
• Other towns: the published sources do not list a separate zoning office; ask the town hall.

Permit fees and trade permits

Fees come from the County’s fee schedule effective July 1, 2026, posted as Inspection Fees on the Building Inspections page.

Re-inspections are $50 per trip. Trade permits must be bought by the licensed contractor doing the work. An owner may do their own electrical, plumbing or mechanical work on a manufactured home only with a permit and must then live in the home for at least a year. The County takes card payments on a Credit Card Authorization Form and asks that card or bank details never be sent by email.

Related charges on the same schedule: Environmental Health site evaluation $250, septic improvements permit $150 (480 gallons per day or less), existing system or permit transfer $100, private well permit $300; Planning flood hazard permit $25; fire prevention inspection $75 for buildings under 25,000 sq ft.

What the building permit application needs

• Plans showing foundation type, floor framing, load-bearing walls and roof framing (truss documents or stick-built sizes and spacing). Plans must be sealed when the job costs over $90,000, the building exceeds 2,500 sq ft or it is part of a prefabricated package.
• The completed application with the licensing affidavit and workers’ compensation form, and a copy of the general contractor’s licence.
• Town zoning approval for sites in or next to a town’s limits or ETJ; elsewhere the County Planner reviews the site plan.
• An elevation certificate in a floodplain, and a no-rise certification in a non-encroachment area.
• A copy of any subdivision restrictive covenants.
• The approved septic plan and the 911 address.
• Lien agent details for projects of $40,000 or more, unless the work is on the applicant’s own existing home.

The County may ask for a deed, survey map or new survey to check setbacks and rights-of-way. An owner may act as general contractor only if they will occupy the building, not sell or lease it, for at least a year after completion. Manufactured homes also need the dealer’s typed bill of sale or a tax moving permit.

Call Building Inspections at 910-296-2124 to book. The County’s homeowner guide says inspections scheduled before 5:00 p.m. are normally done the next workday. Each repeat trip costs $50.

Manufactured homes are set up following the manufacturer’s manual (or the state manufactured home regulations for a used home without one), and the manual must be on site for the inspector.
