According to HousingWire, researchers at the University of Alabama examined nearly three million home sales across multiple states over more than a decade to test whether building code updates actually drive up housing prices. The study tracked instances when states adopted modern residential codes and looked at what happened to home prices afterward. What they found pushes back against a common claim that's been repeated for decades: that stricter building codes make homes more expensive and therefore less affordable.
The research reveals that while construction costs have certainly risen, there's no clear evidence that building code adoption itself is the culprit behind higher home prices. When you look at all the factors that actually shape what homes sell for—things like land costs, labor, interest rates, neighborhood appeal, and basic supply and demand—building codes don't appear to be a consistent driver of price increases. In fact, the researchers even noticed that prices sometimes went down after codes were adopted, at least when looking at newer homes.
Here's what I think gets overlooked in most affordability discussions. People tend to focus only on that purchase price, but owning a home costs money well beyond signing the papers. A house that floods regularly, develops leaks, or triggers constant insurance claims isn't affordable just because you paid less for it upfront. According to the article, real affordability has to account for how durable a home is, whether you can actually get insurance for it, and how well it holds up when disaster strikes. That matters increasingly as insurance becomes harder to find and more expensive in disaster-prone areas.
The reporting also highlights the broader economic case for modern codes. Homes built to current standards typically qualify owners for lower insurance premiums, and they perform far better when storms or other disasters hit, which means fewer deductibles and less disruption. Studies referenced in the piece suggest that every dollar spent on adopting modern codes returns roughly eleven dollars in benefits through reduced disaster losses and faster recovery.
The article acknowledges that the housing affordability crisis is real and serious, but suggests that the actual tools we need are different ones—things like addressing inflation, increasing housing supply to match demand, exploring methods like off-site construction, and expanding financing options. Rolling back building codes probably isn't the answer to a shortage of homes or families struggling to save for down payments.
What I'm seeing locally here in the Bay Area and throughout the East Bay is that resilience and safety are becoming more central to what people value in a home purchase. Buyers are increasingly thinking about long-term costs, insurance availability, and how a property will perform in our specific weather and seismic environment. A home that costs less to buy but drains your wallet through repairs and insurance headaches isn't the deal it appears to be. These findings suggest that the conversation around affordability needs to be more sophisticated than just looking at the sticker price.
