Sonoma County, California
Sonoma County runs from the Russian River wine districts and Santa Rosa's metro core to the Sonoma Coast and the Petaluma and Sonoma valleys. Wine, tourism and North Bay commuting drive the market, and the 2017 Tubbs and 2019 Kincade fires left rebuilding, fire-hazard zoning and insurance availability as the dominant development constraints alongside community separators and urban growth boundaries.
