Do you need a building permit in Martin County, North Carolina?

Yes, for work covered by North Carolina law. Construction, reconstruction, alteration, repair, movement, removal or demolition generally requires the applicable State Building Code permits before work begins, subject to statutory exceptions1. Martin County Building Inspections provides permitting and inspection services throughout Martin County, including Bear Grass, Everetts, Hamilton, Hassell, Jamesville, Oak City, Parmele, Robersonville and Williamston2. The North Carolina State Building Code applies in Martin County13. After permitted work is complete, the building cannot be occupied until the inspection department issues the required certificate of compliance or a temporary certificate of occupancy14.

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 inspections@martincountync.gov11. The office receives applications and supporting information, issues or denies permits, performs code-compliance inspections, and issues or denies certificates of compliance and occupancy15. Permits are issued on weekdays during the hours published by the office, with cash or check accepted15. Martin County also publishes a fee schedule with charges that vary by construction type, square footage, electrical amperage, plumbing work and other project measures16. Confirm the forms, inspections and total fees for the exact project scope before starting work11.

Does Martin County have zoning?

Yes. Martin County's Unified Development Ordinance applies to the use and development of all land in Martin County unless the ordinance expressly exempts it, including land owned by municipalities3. Residential structures in Martin County must sit 30 feet from the front lot line, 10 feet from the side lot line and 20 feet from the rear lot line8. Up to three principal residential structures may share one unsubdivided tract, but only under a site plan approved by the Planning Administrator and only where lot area, width and setbacks allow it8. In the WS-IV watershed districts, a new residential lot generally cannot be smaller than one-half acre (20,000 square feet), or one-third acre without a curb and gutter street system, unless it is an approved cluster development17. Towns may also have their own zoning, and the county's manufactured-home instructions require a zoning permit when the site is within town limits7. We could not confirm whether Martin County's municipalities run separate zoning, or set a minimum dwelling size, so ask Martin County Building Inspections and the town before designing11.

How do septic permits work in Martin County?

For property anywhere in Martin County, submit the on-site wastewater application to the local Martin-Tyrrell-Washington District Health Department office; most Environmental Health services require a fee4. When an approved wastewater system is unavailable, a residence cannot be constructed, located or relocated until the local health department issues an improvement permit and construction authorization, unless a listed alternative permit option applies18. Environmental Health evaluates soil quality, topography and intended use, then issues or denies the septic permit under state criteria4. The septic system must be inspected before it is covered or placed into use19. Only 7.6% of Martin County soils are rated without severe limitations for a conventional drain field, so obtain the site evaluation before fixing the house location20. Contact Environmental Health at 210 West Liberty Street, Williamston, NC 27892 or 252.793.166221.

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. County-regulated travel trailer parks must give each space at least 2,000 square feet and a 35-foot setback from the public street right-of-way, but that rule covers parks, not a single RV on your own parcel2223. Ask Martin County Building Inspections about the parcel and proposed use before moving an RV onto the site as a residence11. North Carolina allows a code-compliant tiny home as a permanent single-family dwelling when the local building official permits it and applicable local zoning and setback requirements are met9; we could not confirm a Martin County rule specific to tiny homes. A qualifying tiny home still needs a Martin County building permit and, where no approved wastewater system serves the site, a septic permit from the district Health Department104. 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 underpinning724.

How do you build a home in Martin County, step by step?

  1. Give the parcel address to Martin County Building Inspections and, if the land is inside a municipality, ask the town which zoning approval applies; the county's setbacks and Unified Development Ordinance apply to the parcel either way3811.
  1. Apply to the district Health Department for the septic permit before fixing the home site; the application triggers a review of the soil, topography and intended use4.
  1. 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 information12.
  1. Submit the building-permit application and supporting information to Martin County Building Inspections, then confirm the applicable fees1516. If you are building your own home and claiming the state's owner-builder exemption from contractor licensing, you must sign a verified affidavit and personally manage the construction and be present at inspections; the exemption does not waive the building permit615.
  1. Schedule Martin County's required building-code inspections as work progresses2.
  1. Obtain the certificate of compliance or temporary certificate of occupancy before moving in14.

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 use2021. Check municipal boundaries and the county ordinance together, because the county's Unified Development Ordinance covers all land unless exempted and a town may add its own zoning permit37. 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 revision1225. For access onto a state-system road, residential driveways are normally exempt from an NCDOT permit, but NCDOT may require one for safety, highway-work, cost or drainage concerns; Martin County is served by NCDOT Highway Division 1, District 326. For carrying costs, the effective property-tax rate is about 1.1%, and the median annual property-tax bill is about $1,1762728.

Watch-outs

  • Martin County's Unified Development Ordinance sets residential setbacks of 30 feet front, 10 feet side and 20 feet rear, so site the house after confirming them with the Planning Administrator8.
  • Martin County RV occupancy, temporary camping, minimum dwelling size and accessory-dwelling rules remain unconfirmed; ask Building Inspections and any municipality with jurisdiction11.
  • Only 7.6% of Martin County soils are rated without severe limitations for a conventional septic drain field, so obtain an Environmental Health evaluation before committing to a house site2021.
  • Development in a mapped special flood hazard area requires a Martin County floodplain permit before work begins, and floodways face additional no-rise or map-revision conditions1225.

Water rights & wells in Martin County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from North Carolina’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellExempt — no permit or water right

Water Use Act of 1967 (G.S. 143-215.22H). Outside a Capacity Use Area there is no withdrawal permit for wells at all; a single-family well is below every threshold.

Limit: household wells exempt; permit only >100,000 gpd inside the CCPCUA

NC DEQ Division of Water Resources — CCPCUA; G.S. 143-215.22H ↗
  • Central Coastal Plain Capacity Use Area (CCPCUA)

    Rules (2002, readopted 2022) impose phased mandatory withdrawal reductions (up to ~75%) from the deep Black Creek and Upper Cape Fear aquifers due to declining artesian levels and saltwater-intrusion risk. Reductions and the permit requirement (>100,000 gpd) apply only to large PERMITTED users; a new single-family domestic well needs no permit and is not curtailed.
