Title 24 Compliance in California
Title 24 is Part 6 of the California Building Standards Code — the state’s Building Energy Efficiency Standards. Every new home, commercial building, addition, and major renovation in California must demonstrate Title 24 compliance before a permit is issued. 5 Star Energy is a certified provider of Title 24 reports and energy compliance documentation, serving builders, architects, contractors, and homeowners statewide from our Redding, CA office with a fast 1-3 business day turnaround.
A Title 24 compliance report is the document your building department requires to confirm that your project’s design meets California’s energy code. Get the report right the first time and your plans clear plan check without costly delays.
What Is a Title 24 Report?
A Title 24 report — often called a Certificate of Compliance or a Title 24 energy report — analyzes how a building’s design performs against the Part 6 energy standards. Our certified energy consultants model your project and document compliance across every regulated system:
- Building envelope — insulation, air sealing, thermal bridging, and continuous insulation
- Windows and glazing — U-factor and Solar Heat Gain Coefficient (SHGC)
- HVAC systems — equipment efficiency, sizing, and duct design
- Lighting — residential and nonresidential lighting power density
- Water heating — equipment type, efficiency, and solar-ready requirements
The finished Title 24 report proves your building meets or exceeds California’s minimum energy performance requirements, so you can obtain your permit and Certificate of Occupancy.
Title 24 for Residential and Commercial Projects
Title 24, Part 6 applies to both residential and commercial construction throughout California. Whether you are building a single-family home, a multifamily development, or a nonresidential commercial building, the code requires a compliant energy report. 5 Star Energy prepares Title 24 documentation for:
- New single-family and multifamily residential construction
- Room additions and significant residential alterations
- Nonresidential and commercial new construction and tenant improvements
- Mixed-use developments
Our Title 24 reports pair naturally with our Title 24 energy calculations for the design-phase compliance model, and — after construction — our HERS testing and field verification confirms the building was built to those compliant plans.
California Climate Zones and Title 24
California is divided into 16 climate zones, and Title 24 requirements change from one zone to the next. A design that complies in coastal Climate Zone 3 may fail in the hot inland Climate Zone 11 around Redding and the Central Valley. Our team models your project against the correct zone and local energy ordinances — see our guide to California’s Title 24 climate zones for a deeper explanation. Getting the climate zone right is one of the most common reasons projects pass or fail plan check.
