Ask five contractors what it costs to build in Silicon Valley and you will probably hear five very different numbers. CountBricks brings clarity. By combining live material pricing, labor databases, and AI-driven voice capture, we generate accurate estimates in minutes. In this guide we break down the current cost per square foot to build a house in San Jose CA, why prices vary widely, and how CountBricks clients keep budgets predictable.
Custom homes: • $425 – $650 per sq ft depending on finish level
Mid-scale spec homes: • $350 – $450 per sq ft
High-end luxury builds: • $650 – $1,000+ per sq ft
These numbers come from aggregated data inside CountBricks.com/estimator, updated weekly from supplier feeds across Santa Clara County. They include labor, standard permits, and a realistic allowance for finishes but exclude land acquisition and impact fees.
1. Labor scarcity: The Bay Area commands top wages, often 20 % above the national average.
2. Material volatility: Concrete, lumber, and copper fluctuate monthly; CountBricks locks pricing snapshots at estimate time.
3. Energy codes: Title 24 and CALGreen upgrades add between $12 and $18 per sq ft.
4. Lot complexity: Hillside access or tight infill sites can raise excavation and staging costs by 10 % – 15 %.
5. Finish level: Imported stone, smart-home systems, and custom millwork quickly push costs beyond baseline.

Our permitting module auto-updates city fee schedules, so allowances stay accurate even as ordinances change.
