Cost to Build a House in Horry County, South Carolina
Building a house in Horry County, South Carolina costs about $163/sq ft in 2026 — roughly $286,880–$365,120 for a 2,000 sq ft mid-range home (construction only, land excluded). 6,418 single-family homes were permitted here in 2025, and the typical existing home is worth $347,441.
That is the South Carolina statewide rate: no public source measures construction cost county by county, so we don't invent a local premium. What does differ by county is measured below.

Build or buy in Horry County?
Building a median-size new home in Horry County costs about $106,690 more than buying the typical existing one. That gap is narrower than the South Carolina average of +46.3%, because existing homes here are pricier than in much of the state — which makes Horry County one of the stronger cases for building in South Carolina.
The two sides are not the same product: the build is brand new at the median new-home size for the South, the existing home is typically older and smaller. Lot cost uses South Carolina's average land share, and local lot prices can be well above or below it. Full South Carolina build-vs-buy comparison

What builders declared on Horry County permits (2025)
The average declared valuation was $217,733 per home, against our $326,000 estimate for a 2,000 sq ft mid-range build. The two measure different things: builders declare a valuation for permit-fee purposes, which routinely understates finished cost, and permits cover homes of every size and finish level. We show both because quoting only the flattering one would be dishonest.

What land adds on top

This is a statewide figure. Lots inside Horry County's built-up areas will run above it and rural parcels below, so treat it as an order of magnitude rather than a budget line.
