According to Zillow Research, something significant happened in the U.S. housing market last year that we haven't seen in over a decade. The national shortage of homes essentially stopped growing. After years of the gap between families needing homes and available housing widening steadily, it held nearly flat in 2024, with the deficit staying around 4.7 million homes.
What drove this turnaround is pretty straightforward. Homebuilders finally caught up with the pace of new families forming. The country added roughly 1.4 million housing units in 2024, which was almost perfectly matched by the number of new families entering the market. This means the number of families sharing homes with other families only grew slightly, and the inventory of available homes available to rent or buy barely budged either. When both sides of that equation move slowly, the gap between them stays flat.
Now, let me be clear about what this does and doesn't mean. Stabilizing the deficit is real progress, but it's not solving the problem. We still have a massive shortage of 4.7 million homes created since the 2008 financial crisis. For the first time in years, though, new supply and new demand were roughly in balance. That's important because it shows we're not falling further behind.
The stabilization is also showing up in how affordable homes are becoming. According to Zillow's data, the share of homes a median-income family can afford stopped dropping in 2024 and has actually started improving since the beginning of this year. Meanwhile, the share of renters in their twenties and thirties who could afford a typical home in their market also stopped declining after falling sharply. This signals that the worst of the affordability crunch may be behind us, even if homes are still worth roughly fifty percent more than they were before the pandemic.
The data does show that deficits are much worse in expensive markets. Boston has the tightest conditions among major cities, and two California markets remain in the top five worst metros. When I look at what's happening here in the Bay Area and the greater East Bay, this stabilization is encouraging news for both buyers and sellers. If the nationwide trend holds, we're moving into a phase where the pressure from chronic undersupply starts easing rather than accelerating. For sellers, that means less of a sellers' advantage that they've enjoyed. For buyers, it means the most punishing phase of affordability decline may be passing, though catching up will take time.
