The Sunbelt is building America's missing homes
Sep 2026
See the 3 Sunbelt growth corridors building fastest, and where infrastructure is falling behind. Is your jurisdiction seeing the change in time?

The U.S. is short an estimated 4 million homes, with some figures inflating that number to 8 million. The Sunbelt is where the country is trying to close the gap. The South and West accounted for 80% of every single-family home authorized nationwide in 2025.
Funding and political will decide how fast infrastructure follows the rooftops. So does visibility. Agencies set capital budgets from population projections and approved development plans. But a plan cannot show how fast farmland is actually becoming subdivision, or how fast pavement is replacing open ground.
What growth looks like at property level
Property intelligence and shows the change and every new roof is a data point. Capture a corridor several times a year and its conversion rate becomes trackable in a way no projection or ground survey can match.
Government agencies decide where the next road widening goes. Plus, knowing where conversion is happening, and how fast, separates getting ahead of the population from permanently catching up.
Three corridors show how differently it plays out:
1. The West Valley, Phoenix
Maricopa County added roughly 42,000 housing units between 2024 and 2025, more than any county in the nation, and for the second year running. Goodyear gained 7,690 residents in the same year, one of the 15 largest increases of any US city
Arizona lawmakers have responded by widening Interstate 10 and planning an entirely new freeway, State Route 30, to serve the West Valley. Both will take years, but the subdivisions are going in now.

Agencies at this pace have moved past the question of what they approved. The question now is what got built, and where the deficit sits today, but approved plans only answer the first.
Property intelligence answers the second, close to real time. Capture a corridor several times a year and the gap between scheduled works and delivered infrastructure becomes measurable.
Nearmap AI extends this further, automatically identifying impervious surface change across entire jurisdictions without manual review.
Shade sits in the same data. Tree canopy across Phoenix census tracts ranges from 2% to 30%, with a median of 11%. In the hottest months, shade can mean a 30-degree difference.
Phoenix has committed more than $60 million over five years to expand tree and built shade, through the first plan of its kind in the country. Directing that spend takes current data on where canopy is thinnest and where new pavement is arriving fastest.
2. The I-35 corridor, north of Austin
Austin crossed one million residents between 2024 and 2025. Hutto, in Williamson County to the north, grew 7.9% in the same year — the thirteenth fastest rate in the nation. That growth reaches Round Rock, Cedar Park, Leander, Taylor, and Hutto as well. Separate jurisdictions, one continuous build-out.

Property intelligence makes the state of that build-out visible as it stands today. Planners see where the gap between approved development and delivered infrastructure is opening, parcel by parcel. The corridor crosses five cities, a county, and several school districts. A shared view keeps capital decisions ahead of the population.
3. The Charlotte metro fringe
The Charlotte-Concord-Gastonia metro reached 2.9 million people in 2025, adding 54,122 residents in a single year. It ranks seventh in the nation for total population gain since 2020.
Charlotte gained more residents than any city in America last year. It was still only the seventh fastest-growing city in its own metro.

Waxhaw, NC
All that growth arrives as hard surface, and Charlotte bills for it.
Detached single-family homes sit in one of four stormwater tiers, from under 2,000 square feet of impervious surface to more than 5,000. Every other property is billed on its actual measured impervious area. A new driveway can move a property into the next tier. So can a pool deck. Across a metro adding this much roof and pavement, the billing roll starts drifting the day the last measurement was taken.
Impervious surface is one of the layers Nearmap AI extracts from every capture. Measuring it several times a year keeps the record current across every parcel, with no field visit, and gives the county time-stamped evidence when a ratepayer disputes a tier.

Planning for what the Sunbelt is becoming
The housing shortfall will not close quickly, and the infrastructure pressure it creates will intensify before it eases. Agencies managing these corridors work with review cycles built for a slower rate of change. What has changed is the ability to see.
Property intelligence gives planners a current picture of what exists on the ground today. More than a decade of consistent capture history sits behind it. Across Phoenix, Austin, and Charlotte, the same capability does the same job: making the gap measurable before it becomes permanent.
For communities rising on the Sunbelt fringe, that visibility is the foundation of infrastructure decisions that keep pace with growth.
