Where Is Title 24 Required in California? Understanding Statewide Energy Code Compliance

Whether you’re a homeowner, contractor, or architect working on a California building project, you’ve probably asked yourself: Where is Title 24 required in California? The short answer? Everywhere.

California’s energy efficiency standards—commonly known as Title 24—apply to virtually all cities and counties throughout the state. They’re not optional. They’re part of the California Code of Regulations and are enforced by local building departments across the board.

At Title24Energy.com, we help clients from Los Angeles to Sacramento, from San Diego to Redding, meet their energy compliance requirements quickly and affordably. If you’re planning a remodel, addition, ADU, or new construction, chances are high that you need a Title 24 report—and our experts are here to guide you every step of the way.

Statewide Coverage: Title 24 Is Required in Every Jurisdiction

Title 24 energy regulations are mandated across the entire state of California. That means no matter where your project is located—from large metro areas like San Francisco and San Diego to small towns like Grass Valley or Ridgecrest—you must comply with Title 24 standards if your construction involves energy-consuming features.

This includes:

• All 58 California counties
• Over 480 incorporated cities and municipalities
• Unincorporated areas governed by county building departments

Each local building authority may have its own plan check procedures, but they all enforce Title 24 as the baseline for energy efficiency. Some even go beyond it, adopting stricter local amendments. That’s why it’s critical to work with a Title 24 expert who understands both state and local energy codes—like the team at Title24Energy.com.

Types of Projects That Require Title 24 Compliance

No matter where in California your property is located, Title 24 applies if your project includes:

• New residential or commercial construction
• Room additions or expansions
• Garage conversions or ADU builds
• Window or door replacements
• HVAC system upgrades
• Lighting or insulation changes
• Solar PV installations for new homes

Even smaller upgrades can trigger the need for a Title 24 report if they impact the energy efficiency of the building. That’s why it’s always smart to contact us before you apply for permits. We’ll help you determine what’s required based on your location and scope of work.

Local Amendments and Jurisdictional Variations

While Title 24 is enforced statewide, some cities and counties adopt local amendments that make the energy code even more stringent. For example, cities like Berkeley, San Jose, and Santa Monica may require higher levels of performance, all-electric building designs, or additional solar capacity.

These local energy ordinances are layered on top of the statewide minimum requirements. Our team keeps up with all of them, so when you order a Title 24 report from us, you’re guaranteed full compliance with both the state and local standards that apply to your specific site.
