Custom Home Building Process in California: Step by Step
What “custom home building” really includes
Custom home building is not only framing. It is program definition, design, engineering, permitting, procurement, construction, inspections, and a disciplined handover. Skipping any stage is how Bay Area schedules blow up.
Step-by-step custom home building process (California)
1) Lot due diligence and budget reality. 2) Schematic design. 3) Design development and engineering. 4) Permit submittal and plan check. 5) Bidding/buyout and long-lead orders. 6) Build through inspections. 7) Punch list and warranty orientation.
What is the complete process of building a custom home in the Bay Area? Those seven stages — with city-specific plan check sitting in the middle.
Build house from scratch: decisions that lock cost
