Frequently Asked Questions
Do I need a building permit for window replacement in California?
Yes. California law requires a building permit for all window replacements. This ensures the project complies with energy efficiency (Title 24), structural safety, and emergency egress codes.
What is the average cost per window in California?
Homeowners typically pay between $600 and $1,500 per window. While materials average $300–$1,000, California’s higher labor rates add $150–$350 per unit, especially in urban centers like San Francisco and Los Angeles.
What is the difference between Retrofit and Full-Frame installation?
Retrofit (Z-bar) installation leaves the existing frame in place and is faster and cheaper, ideal for stucco homes. Full-frame replacement involves removing the entire assembly down to the studs, allowing for better insulation and water-proofing but at a higher cost.
Can I install single-pane windows in California?
No. Under current Title 24 regulations, replacement windows must be at least double-paned with a Low-E coating to meet the state's energy efficiency requirements.
