Common Questions

Yes, a building permit is required for all window replacements in San Francisco. While in-kind replacements can now be processed online via the PermitSF portal, any changes to size or location require an over-the-counter permit with plan review.

As of January 1, 2026, California's Title 24 energy code requires all replacement windows to meet a U-factor of 0.30 or less and a Solar Heat Gain Coefficient (SHGC) of 0.23 or less to ensure compliance.

Homeowners typically pay between $250 and $600 for contractor permit coordination, in addition to city fees which are calculated based on the project's total valuation (often 1-3% of the total cost).

Yes, buildings in historic districts or Landmark Category A require SF Planning approval. These projects often mandate specific materials like wood and custom profiles to match original architecture, which can increase costs by 50% to 100% compared to standard vinyl.

San Francisco costs are roughly 40% higher than the national average due to labor rates being 25% higher, complex multi-story access requirements, and strict seismic and coastal moisture-resistance standards.
