Where America Is Building: The Q3 2026 New-Construction Map

By Kukun Research

Everyone in lending knows the national housing-starts number. It moves markets and makes headlines, and it is almost useless for deciding where to put a dollar. “Starts were up this quarter” tells a construction lender nothing about which submarkets are actually breaking ground — which is the only thing that matters when your borrower is a builder.

So we read the permits instead. In Q3 2026, 178,745 residential new-construction permits were recorded across Kukun’s national database — more than 84,000 of them explicitly single-family homes. Read at the county and ZIP level, that’s not a macro statistic. It’s a map of where ground is breaking right now, and it points somewhere specific.

It’s a Sun Belt story — and a different map than home equity

The states leading new construction are not the states leading home-equity demand. Our Renovation-HELOC Index is led by California and the established coastal metros. New construction is a Sun Belt phenomenon:

Texas (29,097 permits), Florida (26,122), North Carolina (18,840), Georgia (17,263), South Carolina (14,754), California (13,454), and Arizona (8,436) lead the country. The borrower who renovates an equity-rich home in San Jose and the builder putting up spec homes outside Charlotte are two different customers, in two different places. If you finance ground-up construction, you’re working the second map — and it doesn’t look like the first.

The real edge: it concentrates, hard

The more useful finding isn’t which states build the most — it’s how tightly construction clusters inside them.

Nationally, the top 25 counties account for 43% of all residential new construction; the top 10 alone hold nearly 22%. And within a single state it’s tighter still: in Georgia, five counties make up 68% of the state’s new construction. In North Carolina, the top five are 60%. In Texas, 55%. In Florida, 49%.

For a construction lender, that is the whole game. You do not need to cover a state. You need the handful of counties where ground is actually breaking — and, inside them, the specific ZIP codes and subdivisions. The top counties in Q3:

• Maricopa, AZ — 5,060
• Spartanburg, SC — 4,878
• Tarrant, TX — 4,287
• Mecklenburg, NC — 4,132
• Hall, GA — 3,813
• Barrow, GA — 3,466
• Orange, FL — 3,289
• Gaston, NC — 3,222
• Horry, SC — 3,218
• Webb, TX — 3,212

Spartanburg County alone filed nearly 4,900 new-construction permits in a single quarter. Each one is a project — and a potential borrower.

Why the permit is the earliest signal in construction lending

A ground-up permit is filed before the construction loan is locked. By the time a builder or owner is comparing financing, the project is already on the public record — address, lot, scope. The lender who waits for the loan application is meeting that borrower late. The permit names the project months earlier, and it names it at a specific address.

That’s the difference between prospecting a metro and knowing exactly where to show up. A county count tells you a market is hot. The permit tells you which lot.

What’s missing from the public number

Housing-starts data and county-level counts are everywhere — Census publishes them, builder associations publish them. What no one has is the actionable layer: every one of these permits as a specific project, tied to an address and the detail behind it (subdivision, square footage, unit type), matched to a lender’s geography and lending box. That’s the gap between a chart and a pipeline.

That’s what Kukun builds. The map above is the free version — where construction is forming. The part a construction lender can actually act on is the project list underneath it, down to the address, for the markets you lend in.

Methodology: Figures are residential new-construction permits in Kukun’s national building-permit database for Q3 2026 (July–September), classified by Kukun’s permit model and joined to property records. “Single-family” reflects permits explicitly tagged as single-family residences; building type is unspecified on a share of records, so single-family counts are conservative. Counts reflect permits in Kukun’s database, not a census of all U.S. permits, and coverage varies by jurisdiction. Figures describe permit volume and geographic concentration; unlike the Renovation-HELOC Index, new-construction permits are not equity-weighted, as newly built homes do not yet carry a valuation.
