Water rights, rainwater law, cottage food rules, right-to-farm protections, livestock zoning, and growing conditions for California landowners and buyers.
Land law varies by county, municipality, and HOA. Verify all information with your county planning department, state water agency, and a licensed attorney before any land purchase or development decision.
Water law
Complex hybrid: riparian, appropriative, and pueblo rights. Groundwater governed by the Sustainable Groundwater Management Act. Contact State Water Resources Control Board (waterboards.ca.gov).

Soil notes
Extremely diverse. Central Valley has some of the most productive agricultural soils in the world (deep alluvial Mollisols and Entisols). Coastal soils are often shallow and sandy. Sierra Nevada soils are thin and rocky. Most California soils need nitrogen.
