Yes. San Francisco requires a building permit for all window replacements visible from the street. Permit and plan review fees in 2026 typically range from $250 to $755 depending on the project valuation.
Properties in historic districts (Article 10 or 11) must match original materials, often requiring custom wood frames. This can increase costs by 50% to 100%, with per-window prices often exceeding $2,500.
San Francisco labor rates are approximately 25% higher than the national average. Additionally, the city's multi-story housing stock requires specialized scaffolding and strict Title 24 energy compliance, adding $200-$400 per unit in overhead.
Under California Title 24, replacement windows must meet strict U-factor and SHGC ratings. Standard double-pane Low-E windows are required, which can save San Francisco homeowners between $100 and $580 annually on energy bills.
