If you're planning a remodeling project in California, Title 24 compliance is mandatory. Here's what homeowners need to know.
What Is Title 24?
Title 24 is California's Building Energy Efficiency Standards. Updated every three years, these regulations set minimum energy performance requirements for new buildings and major renovations. The current standard (Title 24-2022) was adopted in December 2021 and took effect January 1, 2023.
How Title 24 Applies to Your Project
Most residential remodeling projects trigger Title 24 compliance. Additions over 5% of existing conditioned space. New windows, insulation, and HVAC systems. Even lighting upgrades over certain thresholds. Your contractor must demonstrate compliance.
Key Title 24 Requirements
Cool roofs reduce solar heat. Insulation minimums for walls and attics. HVAC system efficiency standards. Lighting power density limits. Smart thermostats on many systems. Water heating efficiency requirements. Solar-ready roofs for new construction.
Cost Impact of Compliance
Compliance typically adds 2-5% to project costs through upgraded insulation, efficient equipment, and solar-ready infrastructure. However, long-term energy savings often exceed these costs within 5-7 years.
Final Thoughts
Title 24 compliance is mandatory for California remodeling projects. Working with knowledgeable contractors ensures compliance while building better, more efficient homes.

Frequently Asked Questions
Do all remodeling projects require Title 24 compliance?
Most do. Projects adding 5%+ of conditioned space, or involving major systems (HVAC, windows, insulation) must comply. Consult local building department for your specific project.
What happens if I don't comply with Title 24?
Projects that don't comply won't pass final inspection. Non-compliant systems may not receive building permits. It's not optional. It's a requirement.
