The Missing Middle: Why Williamson County Can't Build Enough Affordable Homes
Why can't Williamson County build affordable housing, and what is being done about it? The question is easier to ask than to answer, but the numbers make the stakes clear. A countywide housing study found only three homes on the market priced under $300,000, while the county also needs thousands of higher-end homes that are not being built. In Franklin, roughly 2,500 renter households and 2,000 homeowner households spend more than half their income on housing.
Start with the numbers
Three homes for sale under $300,000, countywide, at the time of the study. That is not a typo. In a county of more than a quarter-million people, the entry level of the market effectively does not exist. Meanwhile the same analysis sees a projected shortfall of more than 10,000 units by 2030, which means the gap is not closing on its own.
Why lower-priced homes are so rare
The economics of new construction explain most of it. Builders price homes against what it costs to buy land, clear it, install utilities, pay impact fees, and build under current construction costs. In Williamson County that math lands most new homes far above the entry-level price band. Builders build what sells at a profit, and at the moment what sells is expensive.
It is not that builders are ignoring the problem. It is that the gap between what a limited-price home can sell for and what it costs to produce one is bigger than a private company can absorb on its own.
The rent burden in Franklin
The shortage does not only show up in for-sale inventory. In Franklin, about 2,500 renter households and 2,000 homeowner households spend more than half their income on housing. Housing experts generally consider costs above 30 percent of income to be a stretch. At 50 percent, almost nothing is left for everything else, and families end up one emergency away from trouble. Those households are the teachers, nurses, retail workers, and service professionals the county depends on every day.
Who bears the cost
When people cannot afford to live where they work, they commute. That means longer drives, more traffic on the interstates, less time with family, and a workforce that is stretched thin. It also means employers in the county compete for workers who can afford the area, which pushes costs up everywhere. The housing shortage is not just a real estate problem. It is an economic one.
What is being done about it
The picture is not entirely bleak. Public-private partnerships have started to move workforce housing forward, including apartment and homeownership projects near the Mack Hatcher Parkway corridor. These projects pair public support with private development to close the gap that the market will not close on its own. They are not enough, not yet, but they are the first real answers to the question of what can be built.
What this means for you
If you are a buyer at the entry level, the honest advice is that you need flexibility, a realistic price range, and a team that knows where the opportunities are. If you are thinking about the county's long-term future, these numbers explain a lot about traffic, schools, and the local economy. And if you are a homeowner, understand that the shortage of lower-priced homes is a large part of why your own value has held up.
