Cost to Build a House in Coffee County, Tennessee
Building a house in Coffee County, Tennessee costs about $165/sq ft in 2026 — roughly $290,400–$369,600 for a 2,000 sq ft mid-range home (construction only, land excluded). 455 single-family homes were permitted here in 2025, and the typical existing home is worth $309,483.
That is the Tennessee 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 Coffee County?
Building a median-size new home in Coffee County costs about $143,795 more than buying the typical existing one. That gap is wider than the Tennessee average of +34.3%, because existing homes here are cheaper than elsewhere in the state.
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 Tennessee's average land share, and local lot prices can be well above or below it. Full Tennessee build-vs-buy comparison

What builders declared on Coffee County permits (2025)
The average declared valuation was $282,425 per home, against our $330,000 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.

This is a statewide figure. Lots inside Coffee 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.
