💬What People Actually Paid
Community❓Common Questions
Yes, a building permit is required for all window replacements in San Francisco, regardless of location or size. For standard projects, over-the-counter (OTC) permits are common, but fees are valuation-based, typically starting at a base of $207 plus variable rates for projects over $2,000.
Homeowners in San Francisco's historic districts often face costs nearly double the standard rate. While modern fiberglass or vinyl replacements average $20,000 for a full home, historic-compliant wood-framed windows can exceed $40,000 due to strict preservation standards and custom manufacturing requirements.
Yes, all replacements must comply with California's Title 24 energy standards. This typically requires double-pane windows with a U-factor of 0.30 or lower. While these units cost $150–$300 more per window than basic models, they qualify for federal tax credits of 30% (up to $600 annually).
In San Francisco's multi-story housing stock, labor premiums of $50–$150 per window are common for second or third-story installations. If scaffolding is required for exterior access, it can add a flat project fee ranging from $250 to $1,000.
