Why homebuilders aren’t building more homes

New home sales are staying in a 600,000 to 700,000 range, limiting permits as builders rely on rate buydowns.

Curated News BriefBased on original reporting by HousingWire (July 24, 2026). The summary below is the Journal’s; the local analysis is original commentary by Omar Murillo.

According to HousingWire, new home builders are facing a challenging situation that explains why housing permits have remained constrained. The reporting shows that new home sales have been stuck in essentially the same range for about a decade, bouncing between roughly 600,000 and 700,000 units annually. Even though new home sales are outperforming existing home sales right now, builders are operating in an environment where existing home sales benefit from higher mortgage rates that have essentially plateaued around 6 percent or above.

The article explains that builders have been sustaining sales by using their own profit margins to buy down mortgage rates for buyers, keeping rates closer to the sub-6 percent level. Many of those profit margins came from the significant price gains builders locked in during the COVID period. However, as these margins continue to shrink from being deployed toward rate buydowns, builders have less financial flexibility to absorb costs and remain profitable.

One key metric HousingWire highlights is the level of completed units sitting in inventory for sale. Historically, when this number exceeds 120,000 units, builders tend to significantly pull back from new construction. Currently, completed units for sale have stopped rising, which indicates builders are hesitant to increase production even at these constrained levels.

The reporting also notes that builder confidence remains weak, with confidence indexes trending low and showing little enthusiasm for growth. This reluctance to build more homes is compounded by mortgage rates that recently hit yearly highs, which will force builders to spend even more of their shrinking profit margins just to move existing inventory.

What I am seeing locally here in the Bay Area and East Bay is that this national dynamic absolutely applies to our market. Our builders face the same margin pressure and inventory challenges as the rest of the country, and until we see genuine improvement in buyer confidence and a willingness from lenders to compete on rates rather than pushing that burden onto builders, we're going to remain in this holding pattern where supply stays artificially constrained and affordability continues to be the core issue for our region.
