SB 15 – A Step Toward More Affordable Housing for First-Time Buyers in Texas

Published June 14, 2025

First-time homebuyer considering housing opportunities in Texas

The Texas housing market is at a critical crossroads. Skyrocketing home prices, driven in part by limited inventory and restrictive local zoning laws, have made homeownership increasingly unattainable—especially for first-time buyers. But change is on the horizon.

Senate Bill 15 (SB 15), recently passed by the Texas House at the time of this article’s publication, proposes a significant shift: reducing the minimum lot size for new single-family homes in the state’s largest cities. This legislation aims to spur the development of smaller, more affordable “starter homes,” potentially unlocking homeownership for thousands of Texans currently priced out of the market.

Understanding the “Missing Middle”

For decades, housing development in many Texas cities has been polarized between large-lot, single-family homes and high-density apartment complexes. The “missing middle”—townhomes, duplexes, triplexes and homes on small lots—has been largely constrained by zoning regulations mandating minimum lot sizes.

SB 15 directly addresses this issue. By allowing homes to be built on smaller footprints, developers can build more units per acre, thereby reducing the land cost per home. This economic efficiency is crucial for delivering housing at a price point accessible to median-income earners.

The Impact of Lot Size on Affordability

At CDS Market Research, our lot price surveys consistently show that land costs constitute a significant and growing percentage of total home prices. In major metros such as Houston, Austin and Dallas–Fort Worth, finding affordable land for new development is increasingly difficult.

  • Reduced land burden: A typical 5,000-square-foot lot might cost $100,000. If SB 15 allows that same land to be divided into two 2,500-square-foot lots, the land basis per home is halved.
  • Increased density: Higher density near transit corridors and employment centers supports local businesses and can reduce commute times.
  • Entry-level product: Smaller lots naturally encourage the construction of smaller homes—approximately 1,200 to 1,800 square feet—which are the type of homes many first-time buyers need.

Looking Ahead

While SB 15 is not a silver bullet for the housing crisis—issues involving material costs, labor shortages and interest rates remain—it represents a critical structural change. It aligns zoning regulations more closely with current market realities and demographic needs.

For developers and municipalities alike, understanding the localized impact of this legislation is paramount. CDS will continue to monitor legislative changes and analyze how reduced lot sizes affect market feasibility, absorption rates and overall community development across Texas.
