Martin County, North Carolina requires building permits countywide, including within its municipalities, through Martin County Building Inspections12. On-site wastewater permits and evaluations go through the Martin County Health Department's Environmental Health Division34. We could not confirm countywide zoning from an official ordinance, so ask Building Inspections and the relevant town about a parcel52.

Do you need a building permit in Martin County, North Carolina?
Yes. Martin County Building Inspections issues building permits and provides inspections throughout Martin County, including Bear Grass, Everetts, Hamilton, Hassell, Jamesville, Oak City, Parmele, Robersonville and Williamston12. North Carolina generally requires the applicable State Building Code permits before construction, reconstruction, alteration, repair, movement, removal or demolition begins, subject to statutory exceptions10. The North Carolina State Building Code applies in Martin County, with enforcement by the authority having jurisdiction11. Permitted work is inspected as it progresses, and a new or altered permitted building cannot be occupied until the inspection department issues a certificate of compliance or temporary certificate of occupancy1213.
Who is the Martin County building department and how do you reach it?
Martin County Building Inspections is at 205 East Main Street, Williamston, NC 27892; call 252-789-4310 or email [email protected]2. The office receives permit applications, performs inspections, and issues or denies certificates of compliance and occupancy2. Martin County publishes a permit-fee schedule effective August 1, 2025, with charges that vary by construction type, square footage, electrical amperage, plumbing work and other project measures6. Published residential charges include $0.20 per heated square foot, $0.16 per unheated square foot, $0.40 per electrical amp and $8 per plumbing drain6. Confirm the required applications and total fees with the office for the exact project scope2.
Does Martin County have zoning?
We could not confirm countywide zoning in Martin County from an official ordinance; ask Martin County Building Inspections whether county rules apply to the parcel52. The county's manufactured-home instructions require a zoning permit when the site is within a town's limits, which confirms that town jurisdiction can change the paperwork2. Before buying or designing, give the parcel address to Martin County Building Inspections and to the applicable town, if any, and ask which zoning, setbacks, minimum dwelling size, accessory-dwelling and lot-coverage rules apply2. North Carolina authorizes counties to adopt zoning in their planning jurisdiction, but that statewide authority alone does not establish Martin County's actual zoning map or rules14.
How do septic permits work in Martin County?
The Martin County Health Department's Environmental Health Division handles on-site wastewater applications, lot evaluations, permits, inspections and repairs34. Environmental Health evaluates soil quality, topography and intended use, then issues or denies a permit under state criteria4. Statewide, an improvement permit and construction authorization are required before constructing, locating, relocating, installing or repairing a wastewater system where an approved sewer system is unavailable15. The system must be inspected before it is covered or placed into use16. Only 7.6% of Martin County soils are rated without severe limitations for a conventional drain field, so obtaining the site evaluation before fixing the house location is especially valuable17. Contact Environmental Health at 210 West Liberty Street, Williamston, NC 27892 or 252.793.16624.
Can you live in an RV or tiny home on your land in Martin County?
We could not confirm a Martin County rule allowing or prohibiting full-time RV occupancy or temporary camping on private land. Ask Martin County Building Inspections about the parcel and proposed use before moving an RV onto the site as a residence2. North Carolina's Residential Code includes a tiny-house path for a dwelling with no more than 400 square feet of floor area, excluding lofts8. A qualifying tiny house still remains subject to Martin County's building-permit process and applicable wastewater approval115. Manufactured homes have a clearer county process: submit the county application and septic documentation, add a zoning permit if the site is within town limits, obtain electrical and setup permits, complete tie-down and utility work, and request inspection before underpinning718.
Building a home in Martin County: the steps, in order
- Give the parcel address to Martin County Building Inspections and the relevant municipality, if any, to confirm which land-use approvals apply52.
- Apply to Environmental Health for a lot evaluation and wastewater approval before fixing the home site415.
- Check the flood map; development in a Martin County special flood hazard area needs a floodplain development permit before work starts and requires a certified plot plan and supporting elevation information9.
- Submit the building application and supporting information to Martin County Building Inspections, then confirm the applicable fees26.
- Schedule required inspections as work progresses12.
- Obtain the certificate of compliance or temporary certificate of occupancy before moving in13.
What should you check before buying land in Martin County?
Start with wastewater suitability: only 7.6% of Martin County soils are rated without severe limitations for a conventional drain field, and Environmental Health bases its decision on soil, topography and intended use174. Check municipal boundaries and ask the relevant offices about zoning because we could not confirm countywide zoning from an official ordinance52. Review flood mapping early because Martin County requires a permit before development in a special flood hazard area, while floodway encroachment needs a no-rise analysis or an approved conditional map revision919. Verify legal road access and any driveway approval with the road authority because a Martin County-specific driveway rule could not be confirmed. For carrying costs, the effective property-tax rate is about 1.1%, and the median annual property-tax bill is about $1,1762021.
