Build vs Buy in California
25-year total cost comparison, construction data, and build feasibility for California (CA).
Building in California: Overview
California's build-vs-buy equation is dominated by regulation: CEQA reviews, Title 24 energy mandates, and local permitting timelines that can stretch past six months in coastal jurisdictions. That said, Prop 13 caps property tax increases at 2% annually — a massive advantage for new-build buyers locking in today's assessed value. Inland markets like Sacramento suburbs, the Inland Empire, and the Central Valley offer construction costs 40-50% below coastal areas, making new builds viable despite the state's reputation for high costs.
