San Francisco’s marine layer and foggy winters mean exterior projects need weather-resistant materials. We specify the right products for SF conditions.
Key Factors That Affect Your Price
- Height above grade — elevated decks need more structure and permitting
- Material — composite premium over pressure-treated
- Railing type — cable and glass are premium vs. wood or aluminum
- Stairs — each stair run adds $2,000–$5,000
- Site conditions — steep lots and limited access add cost
Permit Requirements
Many deck construction scopes in San Francisco require permits through the San Francisco Department of Building Inspection (DBI). Permit fees typically add $500–$3,500 to a project’s total. A licensed contractor should pull all required permits — if a contractor suggests skipping permits on significant work, that is a red flag.
