South San Jose Housing Market: A Hidden Repricing Event?

Summary

South San Jose's housing market is facing a significant repricing, not due to a single large project, but because of a fundamental shift in what's allowed on land, a factor most homeowners are overlooking. California's SB 79 law, enacted last October, significantly increases housing density allowances within a half-mile of high-quality transit stops, permitting four to seven stories near major stations. This law, combined with ongoing transit improvements like the Eastridge to BART connector, is making transit-adjacent land more valuable. Projects like the 305-unit development at Cambrian Park Plaza and VTA sites at Blossom Hill and Branham stations illustrate this trend, bringing new housing, retail, and changing the comparative sales data for existing single-family homes. Crucially, Coyote Valley's permanent protection from large-scale development means all new housing must occur within existing urban footprints, intensifying demand on current single-family lots. Simultaneously, grid infrastructure upgrades are being prioritized in areas slated for future growth, signaling long-term development bets. For homeowners, this means their property is now comprised of three distinct assets: the house, the land whose legal use has been upzoned, and its location within a constrained, in-demand area. This convergence of forces suggests that the 'highest and best use' of land is changing, impacting timing for sellers, encouraging ADUs or remodels for owners staying, and presenting planning opportunities for families. The market is being repriced from below, with comps shifting away from older sales data.
