Buying Land in Alamance County, North Carolina

A Piedmont county on the Triad-to-Triangle corridor

Alamance County sits in the north-central Piedmont, with Graham as the county seat and Burlington as its largest and most economically active city. Geographically, the county's defining feature for a land buyer is its position directly on the I-40/I-85 corridor connecting the Piedmont Triad (Greensboro/Winston-Salem) to the Triangle (Durham/Chapel Hill/Raleigh) -- a location that has drawn substantial manufacturing, logistics, and residential development interest to the corridor in recent years, particularly near Mebane on the county's eastern edge.

That growth pressure is real but uneven: land close to the interstate exits and the county's incorporated towns sees the most development interest and the highest likelihood of rezoning activity, while the county's more remote farmland -- particularly toward its southern and western edges -- remains genuinely agricultural and comparatively insulated from that pressure, at least for now. A buyer should treat 'Alamance County land' as spanning both patterns rather than assuming either one applies uniformly.

Countywide zoning through a Unified Development Ordinance

Unlike a meaningful share of North Carolina counties that have never adopted zoning outside their towns, Alamance County has real countywide land-use regulation: a Unified Development Ordinance (UDO) that took effect June 21, 2021 and has been amended several times since, most recently in December 2024. The UDO consolidates what used to be separate zoning, subdivision, and floodplain ordinances into one document administered by the county Planning Department, and it governs unincorporated land outside any municipality's own zoning jurisdiction or extraterritorial planning area.

Because the UDO has been amended multiple times in just a few years, do not rely on an older printed copy or a general description of 'Alamance County zoning' -- pull the current version, or better, call the Planning Department directly, to confirm your parcel's specific zoning district, its by-right and special-use categories for agricultural or residential development, and any recent amendment that might affect a subdivision or rezoning plan.

Septic and well permitting through county Environmental Health

Septic (onsite wastewater) and private well permitting in Alamance County runs through the county's own Environmental Health section -- offices in Burlington -- rather than a multi-county district health department, which is the model used in several other North Carolina counties covered on this site. That generally means your site evaluation, design review, and inspection are all handled by the same local office throughout the process, though appointment lead times still vary seasonally, particularly during peak spring and summer building months, so call ahead rather than assuming a fast turnaround.

As with the rest of North Carolina, the technical septic and well construction standards are written at the state level and administered locally -- see the state framework this page builds on for how that split works, and confirm current fees, application forms, and soil-evaluation requirements directly with Alamance County Environmental Health before you count on a specific lot being buildable.

Private well contamination near Swepsonville

One more locally specific issue worth knowing about regardless of where in the county you're looking: private wells in and around the Swepsonville community have tested for PFAS ('forever chemicals') at levels far above EPA drinking-water limits, tied to a county-owned landfill and a nearby biosolids application field -- a documented, currently litigated contamination event (a 2026 lawsuit names Alamance County itself, along with Burlington and Graham, as defendants). See our dedicated well-water page for the details and what to check if your parcel is anywhere near that area.

What to verify before you buy

Start with the Planning Department to confirm the UDO zoning district and permitted uses for your specific parcel, especially if it sits anywhere near the I-40/I-85 corridor or one of the county's towns, where rezoning activity is more common. Pair that with an early call to Environmental Health about site suitability and scheduling if your plan depends on septic approval, and check whether the parcel falls within any municipal extraterritorial jurisdiction, which would shift zoning authority away from the county entirely.
