Two offices in one county seat: who signs off on your pour
Lillington is the Harnett County seat, so the Town and the County both keep permit desks inside it. The Town's Planning & Inspections department says its inspectors cover "Lillington's corporate limits and Extraterritorial Jurisdiction (ETJ)," and it lists four building inspectors. Harnett County Central Permitting handles septic, E911 addressing and the fire marshal from its own building, so you can end up working with two offices in the same town.
Here's the catch for flatwork: the Town's Residential Construction Permit names dwellings, garages, storage buildings, decks and screened porches. It doesn't name driveways, patios or slabs. The Town's own FAQ says most projects will need a permit and tells you to ask the Planning Technician if you're unsure. So here's what we tell every Lillington customer: call Planning & Inspections with your address before the forms go up, and ask whether the lot sits inside the limits or the ETJ. Our permit guide has the questions to ask at any NC counter.
Fuquay and Norfolk sand, Aycock silt and a few mined lots
Soil-map readings at 40 spots inside the town limits tell a mixed story. Fuquay loamy sand and Norfolk loamy sand take six spots each. Three spots land on Pits-Dumps complex, and the rest scatter across Aycock silt loam, Roanoke loam, Nason silt loam and Wagram loamy sand. Per the Fuquay series description and the rest of the NRCS data, Fuquay, Norfolk, Aycock and Wagram are all well drained, so rain clears out of a driveway base fast. Nason is a clayey soil, and the map shows it on 15 to 25 percent slopes. Roanoke is poorly drained and occasionally flooded.
That mix is why we won't quote a base depth from the road. Pits-Dumps means mined or filled ground, and fill is where a slab settles. On a lot like that we probe the subgrade, dig out soft pockets and rebuild the base in compacted lifts before a form goes up. On the sandy Fuquay and Norfolk lots the work is compaction, because loose sand shifts under a load until it's rolled tight. A Nason slope gets a pad shaped so water runs off the low edge instead of sneaking under the slab. Ask the concrete driveway contractors in Lillington you're comparing how they'd test a lot like yours, because a flat price that ignores the ground is a guess.
Pours in Lillington are priced by the square foot, $7 to $12 per sq ft, and tear-out of an old pad adds $1.50 to $4 per sq ft. The sizes below are examples, not quotes.
| Job | Size | Per sq ft | What it comes to |
|---|---|---|---|
| Two-car pad, new pour | 24x30 (720 sq ft) | $7 to $12 | $5,040 to $8,640 |
| Tear-out and haul-off of the old 24x30 pad | 720 sq ft | $1.50 to $4 | $1,080 to $2,880 |
| Third-car extension beside an existing driveway | 12x24 (288 sq ft) | $7 to $12 | $2,016 to $3,456 |
| Long driveway to a house set back from the road | 12x100 (1,200 sq ft) | $7 to $12 | $8,400 to $14,400 |
Square-foot math only. Fill under the lot, slope, truck access and the apron at the road move the number. We give a free written estimate after we see the site.
