Buying Land in Martin County, North Carolina

No countywide zoning: three towns zone, the rest of the county does not

Martin County is one of the North Carolina counties that has never adopted a general zoning ordinance covering its unincorporated territory. Zoning here is strictly municipal: Williamston (the county seat), Robersonville, and Hamilton each maintain their own zoning ordinances and can answer zoning questions for land inside their limits, but land outside all three towns is not subject to any county-level use or density zoning at all. That is consistent with the pattern described on the North Carolina state page -- roughly a fifth of the state's hundred counties have no zoning outside their municipalities, and Martin County is one of them.

For a buyer, that absence of countywide zoning is a real double-edged fact. On one hand, it generally means fewer use restrictions and more flexibility for agricultural, residential, or small-scale commercial use on rural land -- there is no county zoning board standing between you and most ordinary uses of the property. On the other hand, it also means there is little to stop a neighboring landowner from putting almost any use next to yours, since no countywide zoning map is drawing lines between residential, agricultural, and other uses outside town limits. The county did adopt a Unified Development Ordinance in 2023 covering subdivision and building standards, so confirm with Martin County Building Inspections what that ordinance does and does not cover for your specific parcel, separate from the zoning question.

Septic and well permitting through a three-county district health department

Consistent with the state's septic framework -- state-written rules, locally administered permitting -- Martin County's environmental health function is carried out by the Martin-Tyrrell-Washington District Health Department, a district health department that serves Martin, Tyrrell, and Washington Counties jointly rather than Martin County alone. That structure is common in North Carolina's smaller, less populous Coastal Plain counties, which often pool environmental health, and sometimes broader public health, staff and resources across county lines rather than each maintaining a fully separate department.

Practically, that means your site evaluation, improvement permit, and construction authorization for a new septic system in Martin County will be handled by district staff who are also serving Tyrrell and Washington County applicants, which can affect scheduling during busy periods. Confirm current turnaround times, fees, and required documentation directly with the district health department before assuming a fast, single-county-style process.

Farmland in a Coastal Plain county moving past tobacco

Martin County was formed in 1774 from parts of Halifax and Tyrrell Counties and named for Josiah Martin, the last royal governor of colonial North Carolina. Its land sits on rich, sandy Coastal Plain soil that has long made it genuinely productive farm country -- tobacco and peanuts were historically the county's dominant crops, and the county even held a formal Agricultural Society hosting annual autumn fairs in the 1850s. The Roanoke River, which runs through the county, served historically as both a transportation route and a defensive line, with a Confederate fort at Rainbow Banks built to protect river traffic during the Civil War.

That agricultural identity has been in real transition for decades. As tobacco farming declined nationally under health-driven demand shifts, tighter regulation, and ultimately the federal tobacco buyout that ended the old price-support and quota system, Martin County's farm economy restructured along with the rest of the tobacco-dependent Coastal Plain. A buyer evaluating a working farm tract here should ask directly what the land has actually been producing in recent years -- soybeans, corn, cotton, sweet potatoes, and other row crops are all realistic possibilities on Martin County's better soils -- rather than assuming the historical tobacco identity still describes current use. See our national guide to farmland for the broader due-diligence checklist that applies to any agricultural purchase.

Solar development: real operating farms, and a brand-new December 2025 ordinance

Solar development has become a genuine, quantified part of Martin County's land-use picture in recent years. Several named, operating solar farms already sit here -- Green Farm in Robersonville, and near Williamston: Williamston Solar (5 megawatts), Williamston Speight Solar (15 megawatts), Meadows PV 1, and Jakana Solar. Until very recently, though, the county had no solar-specific permitting ordinance at all -- an issue the county's own tax office flagged -- and the Board of Commissioners closed that gap by unanimously adopting a new solar energy ordinance in December 2025, adding required setbacks, vegetative buffers and screening, public hearings, and explicit protections for wetlands, flyways, historical sites, and cemeteries. See our dedicated wind-solar-leasing page for this county for the full detail if a solar lease is part of your plan for the land.
