Local context for San Francisco
San Francisco permits are issued by the Department of Building Inspection, which uses an online tracking portal going back to the 1980s. SF enforces the 2013 Mandatory Soft Story Program, which required retrofits on roughly 4,800 wood-frame buildings with five or more units that were permitted before 1978. California Title 24 energy code, updated for 2025 and effective January 1, 2026, also applies to most remodel and replacement projects.

Look for licensed and insured contractors with at least 3 years of experience. Verify their license with the California licensing board, check Google reviews and BBB ratings, ask for 3+ written quotes, and request references from recent projects in the San Francisco area. Never pay more than 30% upfront.
The best material depends on your climate and budget. Composite decking (like Trex or TimberTech) is the most popular choice in California due to low maintenance and 25-30 year lifespan. Pressure-treated wood is the most affordable at $23-$59 per sq ft installed. Cedar offers natural beauty but requires regular sealing.
A typical 200-400 sq ft deck takes 3-7 days to build once the permit is approved and materials are delivered. Permit approval in San Francisco can take 1-4 weeks depending on your local building department's workload. Plan for 4-8 weeks total from signing a contract to project completion.
Ask about their license and insurance coverage, who pulls the building permit, their warranty on labor and materials, a detailed written estimate, their timeline, and whether they use subcontractors. Also ask to see photos of recent deck projects in San Francisco and request at least 2-3 references.
If your building is already classified and retrofit is complete, it does not affect most remodels. If the building is soft-story and not yet retrofitted, DBI generally requires the retrofit to be in progress or completed before signing off on major permit work.
DBI plan review routinely coordinates with Planning, Historic Preservation, Public Works, and Fire. For projects over 45 years old or in a historic district, expect an extra 4 to 8 weeks for historic preservation clearance beyond the basic DBI review.
