Ever fall in love with a wooded Nebo lot and wonder, “Can I actually build here?” You’re not alone. In McDowell County, the biggest surprises usually come from three places: septic feasibility, road access, and zoning. A little homework up front can save you time, money, and headaches later.
In this guide, you’ll learn how to verify septic potential, confirm both legal and physical access, and understand the zoning basics that shape what you can build. You’ll also get a clear checklist, red flags to watch for, and who to call locally for answers. Let’s dive in.
Septic basics in Nebo
Most unserved parcels around Nebo rely on a private onsite wastewater system. Whether a lot can support a conventional system depends on soils, slope, setbacks from wells and streams, and space for both a primary drainfield and a future replacement area. The county issues permits and enforces state rules, so the process and approvals run through McDowell County Environmental Health.
If a lot does not fit a conventional system, you might still have options. Alternative or engineered systems can sometimes work, but they typically cost more and may require electricity, monitoring, and maintenance contracts. Your first step is always a site evaluation by county environmental health staff or a licensed soil scientist.
Verify septic feasibility
Before you write an offer, confirm that a septic system is realistic for the parcel. Here’s how to approach it:
- Start with a soil and site evaluation. A county environmental health specialist or a registered soil scientist will assess soil type, depth to seasonal water, slope, and setbacks.
- Ask about system types. Confirm whether the site can support a conventional system or if an alternative design is likely.
- Verify space for a reserve area. The county typically expects a designated area for future replacement.
- Plan for access. Make sure excavation equipment can reach the proposed drainfield without overhead or bridge limitations.
- Gather records for existing systems. Request the septic permit, as-built or site plan, installation date, any repair permits, and inspection or maintenance reports if it is an advanced system.
When you are ready, submit the design and application to McDowell County Environmental Health. After installation, the county will inspect and issue final approval when the system meets requirements.
Access: legal vs physical
Access can look obvious and still be complicated. You need both legal rights and practical, drivable access to the build site.
- Legal access is public road frontage or a recorded easement in your deed. A survey and title search confirm this.
- Physical access is whether vehicles and equipment can actually reach the site. Steep grades, unpaved stretches, culverts, or narrow bridges can limit deliveries and construction.
Check who maintains the road you will rely on. State-maintained roads are handled by NCDOT. Private roads and driveways are maintained by owners or associations, and you should confirm how costs are shared.
Driveways and NCDOT permits
If your driveway connects to a state-maintained road, plan on applying for a driveway permit. NCDOT looks at sight distance, drainage, and sometimes improvements to make access safe. Start early so the driveway layout and septic field do not conflict.
If your access is private, review any recorded maintenance agreements and confirm year-round service. Ask who pays, whether a reserve fund exists, and how decisions are made. Good documentation helps avoid disputes later.
Easements and private roads
Easements set rules for how you and others can use the land. Read them closely and verify they are recorded.
- Shared driveway easements often include maintenance and cost-sharing details. Make sure the language allows construction equipment and 24/7 vehicular access.
- Utility easements may limit where you can place a house or drainfield. Confirm there is no conflict with your planned building envelope.
- Conservation easements or restrictive covenants can restrict clearing, building footprints, or further subdivision.
Your title company or real estate attorney can confirm legal access and help you understand the practical impact of each easement.
Zoning and land-use checks
Nebo is an unincorporated community in McDowell County, so county planning and inspections handle zoning and building permits. Zoning determines what you can build, setbacks, and whether certain uses need special approvals.
Ask McDowell County Planning and Inspections for the zoning designation on your parcel and a summary of permitted uses and setbacks. If you need written confirmation for a lender or your own records, request a zoning confirmation letter. Keep in mind that minimum lot size for a home and the area needed for well and septic can differ.
Subdivision rules can also factor in, especially for newly divided tracts. If the land was recently subdivided, confirm the plat and any road standards, as well as any conditions that affect your plans.
Floodplains, slopes, and wetlands
Environmental constraints can shape your site plan and budget. Check these early:
- Floodplains. Use FEMA flood maps and ask county planning whether the parcel sits in a regulated floodway or floodplain. Building in these areas can require special foundations and can limit where a septic drainfield can go.
- Steep slopes and erosion control. Steep ground can increase construction costs, affect driveway feasibility, and limit septic options.
- Streams, wetlands, and buffers. Certain waters and wetlands trigger state and federal rules. If you suspect wetlands, consult NCDEQ, the U.S. Army Corps of Engineers, or a wetlands professional.
Step-by-step due diligence
Use this sequence to keep your process clean and efficient:
- Confirm legal access
- Order a title search to verify public road frontage or a recorded, appurtenant vehicular easement.
- Get a current survey or commission one. The survey will confirm boundaries, easements, and building envelopes.
- Verify zoning and site constraints
- Contact county planning for the zoning designation, setbacks, and any overlays.
- Pull FEMA flood maps and ask about local floodplain rules.
- Check for wetlands and stream buffers if any areas look saturated or mapped as such.
- Assess septic and well feasibility
- Request any existing septic records from county environmental health.
- Schedule a soil and site evaluation. Ask about conventional vs alternative systems and reserve area requirements.
- If you need a well, confirm separation distances from septic and review any available well logs or test results.
- Evaluate physical access and utilities
- Drive the access route in different weather if possible. Look for steep grades, soft areas, or narrow bridges.
- If connecting to a state road, plan for the NCDOT driveway permit.
- Verify availability of electric and communications service. Ask where the nearest connection points are and whether extensions are needed.
- Price the work
- Get estimates for septic installation, driveway construction, grading, and well drilling.
- Ask contractors about equipment access and any improvements needed to reach the site.
- Build contingencies into your offer
- Include a septic feasibility and permitting contingency.
- Include a driveway permit and legal access contingency where applicable.
- Reserve the right to approve survey, title, and easements.
Red flags to pause on
- No recorded access or unclear easement language.
- No feasible septic area after evaluation.
- Parcel within a regulated floodway or with frequent flooding.
- Heavy easement restrictions that reduce the buildable area.
- Private roads without maintenance agreements or clear cost-sharing.
If any of these appear, dig deeper or renegotiate timelines and contingencies before you proceed.

Who issues septic permits in McDowell County?
- McDowell County Environmental Health handles onsite wastewater permits. You will need a site and soil evaluation and a system design to apply.
What if my lot fails a conventional septic test?
- An engineered or alternative system may still be possible, subject to county and state approval. These systems often cost more and can require ongoing maintenance.
How do I confirm legal road access to a parcel?
- Order a title search and a current survey. Look for public road frontage or a properly recorded easement that allows vehicular access and construction equipment.
Do I need a permit for a driveway to a state road?
- Yes, NCDOT typically requires a driveway permit for access to state-maintained roads and may set sight-distance and drainage requirements.
