ADU Market in Foster City.
Foster City is a unique planned community built on reclaimed land in the San Francisco Bay, defined by its lagoon system, waterfront parks, and family-friendly neighborhoods. Visa's global headquarters anchors the local economy, and the city's excellent schools and safe streets make it perennially popular with families. ADUs in Foster City benefit from the city's consistency — predictable demand, stable rents, and a community that takes pride in its quality of life. The lagoon and water-view properties offer particular ADU advantages.
Foster City ADUs rent for $2,300–$3,500/month. Lagoon or water-view ADUs command 10–15% premiums. The market is stable with consistent demand from Visa employees and Peninsula families.
