Most families who call BKA Builders about a build-on-your-lot home in Greensboro have already fallen for a piece of land. They have driven the road. They have stood on the soft pine straw. They have pictured the front porch. And almost without exception, the very next thing they ask is the right question: can we actually build here, and what is it going to cost us in surprises if we do?
That question has a real answer. After 25 years and hundreds of homes across the Triad, the same six or seven issues turn up again and again — and almost all of them are knowable before you sign anything. This guide walks through how BKA Builders evaluates a lot, what the deal-breakers tend to be, and how the process differs across Guilford, Forsyth, and Alamance counties.
Start with the soil, not the sunset
The number one mistake Triad buyers make is falling for the view before they understand the dirt. The North Carolina Piedmont sits on a band of red clay over weathered granite, gneiss, and schist, and the suitability of that subsurface for a septic system, a foundation, or a basement varies enormously from one parcel to the next — sometimes within the same five-acre tract.
Before BKA Builders signs a contract to build on a piece of land a client is considering, three soil-related questions need answers:
- Does the lot perc? If the property is outside a municipal sewer service area — which is true for a large share of the buildable land in northern Guilford, Stokesdale, Browns Summit, and the rural edges of Forsyth — the home will need a septic system. Whether one can be permitted depends on a perc (percolation) test conducted by the county environmental health office.
- What does the soil scientist say? A licensed soil scientist's pre-purchase evaluation is faster and cheaper than a formal county perc, and it tells you up front whether a parcel is likely to qualify and where on the lot the system would have to go. It is the single best $400-$700 a Triad land buyer can spend.
- Is there a viable foundation footprint? Slope, rock, and groundwater all affect whether the home can sit where the client wants it to sit. A lot can perc and still be expensive to build on if the only flat area is in the wrong place.
Septic vs. sewer in the Triad: what actually changes
Roughly speaking, parcels inside Greensboro, High Point, Winston-Salem, and Kernersville city limits are on municipal sewer; nearly everything north of Lake Brandt Road, east of the Haw River, and most of Summerfield, Oak Ridge, and Stokesdale is on septic. The line is not perfect — water and sewer service maps are published by each utility and worth pulling before any offer.
The cost difference is meaningful. A conventional septic system in Guilford County typically runs $6,000 to $12,000 installed in 2026 dollars, depending on tank size, drainfield length, and pump requirements. A "pretreatment" or low-pressure pipe system on a marginal lot can push that to $18,000-$30,000. Sewer connection inside city limits is usually a flat tap fee plus the lateral run — most commonly $4,000-$8,000 total — but the lot itself tends to cost more to begin with.
The right question is not "is septic good or bad?" but "is this specific lot a good candidate, and what will the system actually cost on it?" A soil scientist's report answers both.
Survey, setbacks, and the buildable envelope
A parcel's deed acreage is one number. The buildable envelope — the area where a home can legally and physically sit once setbacks, easements, slopes, floodplain, and septic drainfield reserve are subtracted — is another, usually much smaller, number.
Before BKA Builders commits to a plan on a piece of land, the team typically wants a current boundary survey (not a tax-map estimate) and a clear understanding of:
- Setbacks. Front, side, and rear setbacks vary by zoning district. In Guilford County's most common rural residential zoning (CU-RS-40), front setbacks are 50 feet and side setbacks are 15 feet. A 1.5-acre lot that looks generous on a listing can shrink fast under those numbers.
- Easements. Power, water, drainage, and access easements are usually recorded on the deed or shown on the subdivision plat. They typically can't be built over.
- Floodplain. FEMA flood maps are public; lenders and insurers care a great deal whether any portion of the footprint sits in a Special Flood Hazard Area.
- Septic drainfield reserve. If the lot is on septic, the county will require not just the drainfield itself but a same-sized "repair area" kept clear of structures, driveways, and heavy traffic. That reserve frequently dictates where the house has to go.
HOA and restrictive covenants: read every line
Many of the Triad's most attractive lots — particularly in the established neighborhoods of Summerfield, Oak Ridge, and the gated communities ringing Lake Jeanette — sit inside an active homeowners' association with recorded restrictive covenants. Those covenants commonly dictate:
- Minimum heated square footage (often 2,400-3,500 sf in upper-tier Triad communities)
- Allowed exterior materials (brick percentages, no vinyl siding, no exposed block)
- Architectural review board approval before construction
- Roof pitch minimums, garage orientation, fencing rules, and outbuilding restrictions
None of these are inherently problematic — most BKA Builders projects easily meet or exceed neighborhood covenants — but they are knowable, and they should be in hand before a client decides which plan or which lot makes sense. A 1,900-square-foot ranch is a perfectly good home; it is not a good home for a lot with a 2,800-square-foot minimum.
County permitting: what to expect in the Triad
Permitting timelines and review depth vary noticeably across the counties BKA Builders works in. As of mid-2026, here is the general lay of the land:
Guilford County
Residential plan review through the Guilford County Planning & Development office typically takes 10 to 20 business days for a standard single-family submittal. Environmental health (for septic permits) is a separate review and is usually the longer pole in the tent for lots outside city service. Build-to-permit for a typical BKA home runs 6 to 10 weeks once a complete package is filed.
Forsyth County
Forsyth's review is comparable in timeline but slightly more documentation-heavy on stormwater and erosion control for any lot that disturbs more than an acre — common when a long driveway or grading is involved.
Alamance County
Alamance is generally the quickest of the three on residential review but has tighter constraints around well placement and drainfield siting in some of the more rural areas to the east. A pre-application meeting is usually worth scheduling.
The single most useful thing a buyer can do during their land due diligence period is call the relevant county's permitting office and ask whether anything specific to the parcel is going to slow a residential submittal. The staff are typically very willing to talk through it, and the answers shape the rest of the process.
The buyers who end up happiest are not the ones who chase the cheapest dirt — they are the ones who do real due diligence and then build with margin in their plan and their budget. — BKA Builders
What BKA Builders looks for in a buildable lot
When BKA Builders walks a lot with a client during the consultation phase, the evaluation checklist is short and consistent. A buildable Triad lot generally:
- Has positive drainage away from the proposed home footprint, with no standing water after recent rain
- Has slope under roughly 15% across the building envelope — anything steeper drives cost quickly through foundation and grading
- Is accessible by a road that can carry a concrete truck (some long, narrow driveways can't, and a temporary access road is its own line item)
- Has utilities — power, water or well capacity, and either sewer access or perc-tested septic suitability — confirmed in writing
- Sits in a zoning district that permits the home the client actually wants to build, at the square footage the client actually wants
- Carries no surprise easements, encroachments, or unrecorded encumbrances
None of those are exotic requirements. They are simply the things that, in the team's experience, separate a smooth 7-month build from a frustrating 12-month one.
A reasonable timeline for the land side
For a family starting from scratch — not yet under contract on a lot — the typical BKA Builders land-and-plan sequence looks roughly like this:
- Weeks 1-2. First consultation with BKA, scope conversation, plan direction, ballpark numbers.
- Weeks 2-6. Lot search (often with Debbie Adams, BKA's licensed NC Realtor, on the deal side). Soil-scientist evaluations on the top two or three candidates.
- Weeks 6-8. Offer, due diligence period, formal perc / survey / title work. HOA covenant review if applicable.
- Weeks 8-12. Plan refinement against the actual lot constraints, selections, contract.
- Weeks 12-20. Permitting, site prep, foundation.
- Months 7-10. Vertical construction through completion.
That sequence assumes nothing unusual. Lot complications, custom design work, or municipal review backlog can shift it. But it is a realistic baseline for what a Triad family should plan around if they are starting today.
The shortcut: bring a builder in early
The single most expensive land mistake families make in this market is putting a lot under contract before a builder has walked it. A 30-minute site visit during the due diligence period — before earnest money is at risk — almost always pays for itself. It catches the drainage issue, the septic problem, the setback squeeze, or the covenant conflict that would have been a budget surprise three months later.
If you are already looking at land in the Triad, or you have a lot under contract and want a second set of experienced eyes on it before you close, BKA Builders does this lot evaluation as part of the first conversation. There is no fee for the initial consultation and no obligation to build.
