What building in Harris County actually involves
Cost per square foot is one number. These are the local conditions behind it.
How busy this market is
Harris County ranks 1st of 223 counties in Texas for single-family permits issued in 2025, accounting for 12.1% 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.

What land adds on top
Land averages 23.9% of finished property value in Texas, which is a markup of about 31% on construction cost. For the $364,000 build above, that implies roughly $112,840 for the lot.
This is a statewide figure. Lots inside Harris 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.

Climate, spec and timing
- 1,625 heating and 3,091 cooling degree days a year in Texas — cooling drives the mechanical budget. (NOAA, 2016-2025 average)
- The median new home in the South is 2,162 sq ft and the Census median contract price there is $157.3/sq ft, excluding land — the same basis as our estimate above. (Census Survey of Construction 2025)
- Texas issued 140,579 single-family permits in 2025 overall. See the 35-year state history.
Reconciling our estimate with permit filings
The average declared valuation on Harris County permits was $316,882 per single-family unit, against our $364,000 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.
