Five years ago, a 0.15-acre infill lot in a transitional neighborhood in Atlanta, Charlotte, or Orlando would have attracted limited builder interest. The economics were challenging small lots require custom designs, tight construction tolerances, and neighborhood-specific permitting that most production builders are not set up to handle efficiently. The suburban fringe, with its large parcels and straightforward entitlement processes, was simply a better fit for the production builder model.
That calculus has changed. In Q3 and Q4 2025, we observed a meaningful shift in builder acquisition strategy across the Sun Belt markets we track, with national and regional builders increasingly willing to pay premiums for infill lots that would have been overlooked in prior cycles. Understanding why this shift is happening and what it means for owners of infill land requires looking at the demographic and regulatory forces that are driving it.
The Demographic Driver: Workforce Housing Demand
The most important driver of infill builder demand is the growing mismatch between where jobs are located and where affordable housing is available. In Atlanta, Charlotte, and Orlando the three Sun Belt markets where we have observed the most significant shift employment growth has been concentrated in urban and inner-suburban employment centers, while affordable housing production has been concentrated on the suburban fringe.
The result is a workforce that is increasingly willing to pay a premium for housing that is close to employment centers, and a buyer pool for infill housing that is deeper and more price-tolerant than it has been in prior cycles. Builders who can deliver a product that meets this demand typically a 1,400- to 1,800-square-foot single-family home or townhome priced between $280,000 and $380,000 are finding strong absorption rates in infill locations that would have been considered marginal five years ago.
The Regulatory Driver: Zoning Reform
The second driver is regulatory. Several major Sun Belt cities have undertaken significant zoning reform over the past three years, reducing minimum lot sizes, allowing accessory dwelling units by right, and streamlining the permitting process for infill development. These reforms have materially improved the economics of infill development by reducing the cost and uncertainty of the entitlement process.
Atlanta's "Atlanta City Design" initiative, Charlotte's "2040 Comprehensive Plan," and Orlando's ongoing zoning code modernization have all created conditions that are more favorable to infill development than existed five years ago. Builders who have invested in understanding these regulatory changes are finding opportunities that their competitors are missing.
What This Means for Infill Landowners
For owners of infill lots in Atlanta, Charlotte, Orlando, and similar Sun Belt markets, the current environment represents a genuine opportunity. Builder demand for infill land is real, it is well-capitalized, and it is being driven by structural forces demographic and regulatory that are not going to reverse in the near term.
The key for sellers is understanding that infill land is valued differently than suburban fringe land. The relevant comparables are not the large suburban parcels that dominate most land sale databases - they are the specific infill transactions that have occurred in your neighborhood or comparable neighborhoods. These transactions are less frequent and harder to find, which means that sellers who do not have access to good comparable data are at a significant disadvantage.
If you own an infill lot in a Sun Belt market and are considering your options, we would encourage you to engage with a buyer who has specific experience in infill land transactions and access to the relevant comparable data. The difference between a well-informed and a poorly informed valuation can be substantial and in the current market, that difference is more likely to favor sellers than it has been at any point in the past decade.
