California is one of the most energy-conscious states in the nation—and the rules to prove it are all outlined in Title 24 of the California Code of Regulations. But if you’re a builder, property owner, architect, or contractor, the biggest question on your mind is likely: Who enforces Title 24 energy standards? Understanding the enforcement process is crucial because non-compliance can delay projects, trigger costly redesigns, or even halt construction altogether.

Thankfully, enforcement doesn’t have to be a mystery. In this blog, we’ll explore exactly which agencies and professionals are responsible for enforcing Title 24, how the enforcement process works, and what steps you can take to ensure you’re always in the clear. If you’re planning a new build, remodel, or energy upgrade, this information will help you stay ahead of the curve and avoid common pitfalls.

The Authority Behind Title 24: California Energy Commission (CEC)

The California Energy Commission (CEC) is the state’s official regulatory body that develops and maintains the Building Energy Efficiency Standards, also known as Title 24, Part 6. While the CEC creates and updates these standards every three years, it doesn’t directly enforce them at the local level. Instead, enforcement is delegated to building departments throughout California.

So, if you’re wondering who enforces Title 24 energy standards in your city or county, the answer is: your local building department. These agencies serve as the boots on the ground, responsible for checking plans, issuing permits, and verifying compliance through inspections and documentation.

How Title 24 Enforcement Works

Here’s a simple breakdown of how Title 24 enforcement typically flows:

Step 1: Permit Application – Before construction begins, you must submit plans to your local building department. These plans must include energy documentation that proves Title 24 compliance.
Step 2: Plan Review – City or county officials review your submitted energy compliance report, usually generated by a certified energy consultant.
Step 3: Field Verification – Once construction is underway, certified HERS raters perform on-site inspections and testing to confirm that installed systems match what was reported.
Step 4: Final Inspection – The building department conducts a final review before issuing the Certificate of Occupancy, ensuring all energy requirements have been met.

Skipping any of these steps can result in rejected permits, failed inspections, or project delays.
