Common Questions

Yes. The San Francisco Planning Department requires a building permit for all window replacements, especially those visible from the street. Permit and plan review fees typically range from $250 to $600 depending on the project valuation.

San Francisco costs are roughly 40% higher than the national average due to labor rates ($200–$400 per window), multi-story housing requiring scaffolding (+$150 per window), and strict Title 24 energy efficiency standards.

For homes in historic districts (Article 10 or 11), wood-framed, historic-compatible windows are often required. These units can cost between $1,500 and $3,000+ each, significantly higher than standard vinyl retrofits.

Yes. Due to earthquake risks, local codes often mandate tempered safety glass and specialized anchored frames, which can add 10% to 15% to the material cost compared to standard installations.
