💬What People Actually Paid
Community❓Common Questions
Yes, in San Francisco, any deck more than 18 inches above grade requires a building permit from the Department of Building Inspection (DBI). This threshold is stricter than the California state standard of 30 inches.
Permit fees typically range from $300 to $1,800 depending on project valuation. Additionally, San Francisco may charge plan review fees at rates up to $399 per hour and residential school impact fees of approximately $3.79 per square foot.
Due to the persistent fog and moisture (e.g., 'Karl the Fog'), composite decking (costing $75–$110 per sq ft installed) or natural Redwood ($60–$85 per sq ft) are preferred for their rot resistance and durability compared to standard pressure-treated wood.
Building on a hillside, common in SF, can increase costs by 20% to 40% due to the need for complex engineering, deeper footings for seismic stability, and difficult site access for material delivery.
