Is this Guilford County lot buildable? A 7-check guide
A vacant lot in Guilford County, NC can lose a big share of its usable land to flood zones, wetlands, stream buffers and soils that will not take a septic system. Check these seven things before you make an offer, or before your due diligence period runs out.
1. Flood zone and floodway
Look the lot up on the FEMA Flood Map Service Center (msc.fema.gov). Zone AE is the 100-year floodplain. Floodway is the part of it where building is most restricted. Guilford County also added flood hazard areas in 2023, so check the county's map as well as FEMA's. What matters is how much of the lot is affected, not just whether the lot touches a zone.
2. Wetlands
Mapped wetlands come from the National Wetlands Inventory. A map is a starting point, not a delineation. If wetlands show up on or near the spot you want to build, plan on a professional delineation before closing.
3. Stream buffers
Parts of Guilford County drain to Jordan Lake, where a 50-foot riparian buffer applies along streams. Clearing and building inside it is restricted. On small lots with a creek, the buffer alone can take a large share of the usable area.
4. Septic soils
If the lot is outside public sewer, it needs a septic system, and that depends on the soil. In North Carolina, the county's Environmental Health office does a soil evaluation and issues an Improvement Permit before a septic system can be built. USDA soil maps show how the soils on a lot are rated for septic, which tells you how hard that evaluation may be. Ask the seller whether an evaluation or permit is already on file.
5. Zoning, and who controls it
Zoning tells you what you can build and how much land you need for it. Lots inside a town or its extraterritorial jurisdiction follow that town's zoning, not the county's. Greensboro, High Point, Oak Ridge, Stokesdale, Summerfield and Pleasant Garden each have their own.
6. Road access
A lot needs legal and physical access. A lot that sits back from the road may depend on an easement. Check the deed and survey for it.
7. Water, sewer and taxes
Outside public service areas, plan on a well and septic. Inside a town, ask the town's utility whether lines can reach the lot and what connecting costs. Also check whether the land is in North Carolina's present-use value program. If it is, a change in use can bring rollback taxes for the current year and the three years before it, with interest.
