Local Market Factors

What building in Washington County actually involves

Cost per square foot is one number. These are the local conditions behind it.

How busy this market is

Washington County ranks 2nd of 73 counties in Arkansas for single-family permits issued in 2025, accounting for 15.7% of all the single-family homes permitted statewide that year.

That puts it among the busiest building markets in the state — deep contractor supply, but also the most competition for their time.

U.S. Census Bureau Building Permits Survey, co2025a.txt (2025).

What land adds on top

Land averages 17.5% of finished property value in Arkansas, which is a markup of about 21% on construction cost. For the $306,000 build above, that implies roughly $64,260 for the lot.

This is a statewide figure. Lots inside Washington 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.

Reconciling our estimate with permit filings

The average declared valuation on Washington County permits was $344,372 per single-family unit, against our $306,000 estimate for a 2,000 sq ft mid-range build. These two numbers are not measuring the same thing and should not match: builders declare a valuation for permit-fee purposes, which is routinely below the finished construction cost, and the permits cover homes of every size and finish level rather than a 2,000 sq ft mid-range one. We show both because the gap between them is itself informative — and because quoting only the flattering one would be dishonest.
