About these estimates

Ranges are derived from KEYSTONE's Bay Area project database and reflect 2024–2025 labor and material costs in the San Francisco Bay Area. They include general contractor overhead and profit at our standard rate. They do not include: soft costs (architecture fees, permits, surveys, geotechnical studies), owner-furnished equipment, or site-specific conditions (hillside grading, foundation complexity, utility upgrades). A binding estimate requires a full pre-construction engagement.
