Nash County, North Carolina requires building permits, with Planning & Inspections handling projects in the county's jurisdiction1. The county's Unified Development Ordinance applies in its planning jurisdiction outside local towns and cities; inside a municipality, obtain the zoning permit from that town23. For sites without public sewer, Nash County requires an existing-system compliance permit or a new wastewater permit before the building permit is issued4.

Do you need a building permit in Nash County, North Carolina?
Yes. Nash County Planning & Inspections reviews construction plans and issues building permits under the North Carolina State Building and Residential Codes110. North Carolina law requires permits before covered construction, alteration, repair, movement or demolition begins, subject to specific statutory exceptions11. Nash County accepts building-permit applications through its Permit Portal, and plumbing, electrical and mechanical work each uses a separate trade permit8. Local inspectors check permitted work as construction progresses, and a new or altered building subject to a permit cannot be occupied until the inspection department issues a certificate of compliance or temporary certificate of occupancy1213.
Who is the Nash County building department, and how do you reach them?
Nash County Planning & Inspections, at 120 W. Washington St., Suite 2110 in Nashville, manages county land-development and permitting work10. Call 252-459-9809 or email [email protected], and submit applications through the Nash County Permit Portal108. Residential projects that require plan review need two full-size paper plan sets, while commercial projects need three8. County building-code jurisdiction generally covers the parts of Nash County outside municipal corporate limits and qualifying municipal extraterritorial jurisdictions, so ask which office controls a parcel near a town boundary14.
Does Nash County have zoning?
Yes, but the administering government depends on location. Nash County's Unified Development Ordinance applies within the county's planning jurisdiction outside local towns and cities2. Property within a town or city's jurisdiction may instead require that municipality's zoning permit; Nash County does not administer every municipal ordinance3. North Carolina exempts qualifying bona fide farm property from county zoning, including an owner-occupied residence built to the applicable residential code on the farm, while nonfarm uses remain subject to zoning7. Nash County's current numeric minimum dwelling size, lot size, setbacks, lot coverage and building height could not be confirmed; ask the zoning authority for the parcel before designing or buying.
How do septic permits work in Nash County?
Nash County Environmental Health evaluates building sites, permits septic systems and inspects installations1516. Where a building will produce wastewater and no public sewer is available, an existing septic system requires a $100 compliance-permit application; a site without an existing system requires a $400 wastewater-permit application4. Submit the applicable application with the site plan through the Nash County Permit Portal4. State law generally requires an improvement permit and construction authorization before installing or repairing a wastewater system, followed by inspection and an operation permit before use or occupancy1718. About 56% of Nash County soils rate free of severe limits for a conventional drain field, so a parcel-level evaluation still matters9.
Can you live in an RV or tiny home on your land in Nash County?
North Carolina's Residential Code recognizes a tiny house of 400 square feet or less, excluding lofts, as a single dwelling unit when it meets the code, but Nash County zoning, septic, utility and permit rules still apply6. Nash County's current rules for tiny-home occupancy and minimum dwelling size could not be confirmed, so ask the zoning authority for the parcel. Broader private-land RV living also could not be confirmed; the available county material addresses only limited RV or travel-trailer use connected with construction, repair, commercial construction or temporary emergencies. For land in the county planning jurisdiction, ask Planning & Inspections; for land within a municipality's jurisdiction, ask that town or city23.
Building a home in Nash County: the steps, in order
- Identify the zoning authority: Nash County outside local towns and cities, or the municipality for property within its jurisdiction23.
- If building your own home without a licensed contractor, file the notarized Owner Exemption Affidavit and intend to occupy the home for the next 12 months5.
- For a site without public sewer, submit the applicable compliance- or wastewater-permit application and site plan through the Permit Portal4.
- Submit the building application through the Permit Portal and provide the required paper plan sets when plan review applies8.
- After plan review and septic approval or construction-authorization status, pay for and obtain the building permit8.
- Schedule required building and septic inspections, then obtain the approvals required before occupancy121813.
What to check before you buy land in Nash County
Confirm whether Nash County or a municipality controls zoning before relying on a listing's description of permitted use23. Ask Environmental Health to evaluate septic suitability; about 56% of county soils rate free of severe limits for a conventional drain field, but the building site still needs parcel-specific review916. Check mapped flood hazards because development such as structures, fill, grading and excavation in a Special Flood Hazard Area requires the local floodplain permitting process19. Confirm legal road access and current driveway requirements with the relevant road authority because Nash County's current access rule could not be confirmed. Nash County's median property-tax bill is about $1,320 per year, with an effective rate near 0.8%2021.
Watch-outs
- An owner-builder exemption does not waive the building permit: it requires a notarized affidavit, an intention to occupy the home for the next 12 months, and may leave separate trade permits in place5.
- Living in an RV on private land is not confirmed as generally allowed; ask Nash County Planning & Inspections or the municipality with zoning jurisdiction before relying on an RV during a build23.
