Hottest (and Coolest) Land Markets of 2026: What Single-Family Permit Data Actually Shows

Building permits are the leading indicator that real estate professionals watch before anything else. Before prices move, before inventory shifts, before agents start talking about a "hot market" — somebody has to pull a permit. The U.S. Census Bureau tracks every single one, county by county, and the 2024-to-2025 numbers tell a story that the national headlines are missing.

The headline version: single-family permits are cooling across the Sunbelt. Texas is down 11.1%. Arizona dropped 20.4%. Florida — which looked flat when you counted apartment buildings — fell 9.9% in single-family permits alone. Nevada is down 21.3%. These are the states that dominated the "hottest markets" lists for the past five years.

But zoom past the state-level numbers and something more interesting emerges: within those cooling states, specific exurban counties are surging. Four of the top 25 fastest-growing counties for single-family permits are in Texas — a state that fell 11.1% overall. Hood County (Granbury, southwest of Dallas-Fort Worth) jumped 83%. Wise County (Decatur, northwest of DFW) rose 81.6%. Taylor County (Abilene) climbed 74%. Washington County (Brenham, between Houston and Austin) grew 81.3%.

The national story isn't "Sunbelt down, Midwest up." It's more specific than that: builders are pulling back from expensive metro cores and pushing into affordable exurban counties — and the permit data shows exactly where.

Why Single-Family Permits, Not Total Units?

We rank on single-family (1-unit) permits only. A single 400-unit apartment project can make a county look like the hottest market in America for one year, then vanish from the data the next. Total-unit rankings are dominated by wherever a large multifamily developer happened to break ground. Single-family permits reflect sustained, distributed demand — individual builders responding to individual buyers. That's the signal a land buyer needs.

The Top 15 Rising Counties

These are the 15 counties with the largest year-over-year increase in single-family building permits (2024 to 2025). Every county listed authorized at least 100 single-family permits in both years, and we excluded counties with reporting gaps in their 5-year data.

#1 Taney County, MO (Branson area) — 273 to 861 SF permits, +215.4%. 5-year trend: Rising.

#2 Marion County, IA — 101 to 255 SF permits, +152.5%. 5-year trend: Rising.

#3 Caldwell County, NC — 224 to 499 SF permits, +122.8%. 5-year trend: Rising.

#4 Madison County, ID (Rexburg) — 186 to 414 SF permits, +122.6%. 5-year trend: Rising.

#5 Clark County, OH (Springfield) — 102 to 225 SF permits, +120.6%. 5-year trend: Flat.

#6 Jessamine County, KY (Nicholasville, south of Lexington) — 248 to 488 SF permits, +96.8%. 5-year trend: Gradually rising.

#7 Talbot County, MD (Easton, Eastern Shore) — 104 to 198 SF permits, +90.4%. 5-year trend: Falling.

#8 Lewis County, WA (Centralia/Chehalis) — 196 to 373 SF permits, +90.3%. 5-year trend: Gradually falling.

#9 Garfield County, CO (Glenwood Springs) — 108 to 201 SF permits, +86.1%. 5-year trend: Falling.

#10 Wyandotte County, KS (Kansas City, KS) — 121 to 222 SF permits, +83.5%. 5-year trend: Flat.

#11 Hood County, TX (Granbury) — 141 to 258 SF permits, +83.0%. 5-year trend: Flat.

#12 Wise County, TX (Decatur) — 217 to 394 SF permits, +81.6%. 5-year trend: Rising.

#13 Washington County, TX (Brenham) — 107 to 194 SF permits, +81.3%. 5-year trend: Falling.

#14 Montgomery County, OH (Dayton) — 349 to 630 SF permits, +80.5%. 5-year trend: Falling.

#15 Clallam County, WA (Port Angeles) — 142 to 255 SF permits, +79.6%. 5-year trend: Falling.

Note that a strong year-over-year jump can occur within a longer-term decline — a rebound from a weak year, not necessarily a new trend. The 5-year direction column shows the full picture. Talbot County MD, for example, surged +90.4% in the latest year but its 5-year trend is Falling. Read both numbers.

The Cooling Markets

The other side of the data is just as useful — possibly more so if you're a buyer looking for negotiating leverage.

Effingham County, GA — 790 to 212 SF permits, -73.2%. 5-year trend: Gradually falling.

Loudoun County, VA — 1,496 to 641 SF permits, -57.2%. 5-year trend: Falling.

Montgomery County, MD — 1,491 to 804 SF permits, -46.1%. 5-year trend: Rising (this is a spike-then-pullback pattern).

Calcasieu Parish, LA — 829 to 448 SF permits, -46.0%. 5-year trend: Falling.

Mecklenburg County, NC (Charlotte) — 6,496 to 3,747 SF permits, -42.3%. 5-year trend: Gradually falling.

A cooling permit count doesn't mean a market is "bad." It often means builders are pulling back because of rising construction costs, tighter lending, or oversupply from the previous boom — all of which can create better conditions for land buyers. Less competition for lots, more motivated sellers, and more realistic pricing.

Worked Example: Kendall County, TX

Kendall County sits just northwest of San Antonio — classic Texas Hill Country, popular with buyers looking for acreage within commuting range of a major metro. Here's what the permit data shows:

5-year single-family permit series: 387 (2021) / 325 (2022) / 310 (2023) / 560 (2024) / 351 (2025).

Year-over-year change: -37.3% (560 to 351).

5-year direction: Gradually rising (the 2021-2025 average is higher than the 2021-2022 average, despite the 2025 pullback).

What does this tell a land buyer? The 2024 spike (560 permits) likely reflected a wave of subdivision approvals and speculative building. The 2025 pullback to 351 suggests builders hit resistance — possibly pricing, possibly absorption rate. If you're looking at land in Kendall County right now, the permit data suggests a market that ran hot and is cooling. That's not a warning sign; it's context for a negotiation. Sellers who listed during the 560-permit year may be more flexible now that activity has dropped 37%.

The Census Bureau reports total housing units authorized, which in Kendall County's case is 100% single-family — there are no multifamily projects in the data.

How to Read Your Own County

Every county's permit data tells a different story. Here's how to interpret the numbers:

Look at the 5-year series, not just the latest year. A single year can spike or dip for reasons that have nothing to do with underlying demand — a large subdivision getting approved, a moratorium being lifted, a reporting delay. The 5-year trend is the signal.

Compare the latest year to the county's own history, not to other counties. A county that goes from 200 to 350 permits is in a very different situation than one that goes from 2,000 to 2,150, even though both added 150 permits.

Pair permit data with price data. Rising permits with rising prices means genuine demand. Rising permits with flat prices may mean speculative overbuilding. Falling permits with falling prices is a true cooling market. Falling permits with rising prices often means supply constraints — builders can't keep up, which is bullish for land values.

Remember what permits measure. A building permit is an authorization, not a completed home. It reflects builder confidence at the time of application, which typically runs 6-12 months ahead of actual construction starts. Permit trends are a leading indicator — they tell you where the market is going, not where it's been.

The FHFA House Price Index provides the price side of the equation. Nationally, home prices appreciated between +0.1% (Florida) and +6.6% (Alaska) year-over-year in the latest data. Your LotSat Full Report includes county-level momentum analysis with both permit trends and price appreciation, so you can see the complete picture for the specific area you're evaluating.

Data Sources and Methodology

All building permit figures come from the U.S. Census Bureau Building Permits Survey, annual county-level flat files (2021-2025). We use the 1-unit (single-family) column only. Home price appreciation comes from the Federal Housing Finance Agency (FHFA) House Price Index, quarterly state-level data.

County rankings apply two editorial filters: a base floor of 100+ single-family permits in both 2024 and 2025, and a series-integrity rule that excludes any county where a single year falls below 20% of its 5-year median (indicating a data reporting gap rather than real market activity). Of approximately 3,050 counties in the dataset, 1,058 survive both filters.
