California Title 24 Energy Compliance: What It Means for Your Renovation

January 8, 2026 · IronNest Construction · 1 min read

Title 24 Part 6 — California’s Energy Code — affects a broader range of renovation projects than most homeowners realise. Understanding when and how it applies helps you plan and budget accurately.

What Triggers Title 24 Compliance

Adding or replacing HVAC equipment, adding lighting circuits, adding conditioned floor area, or changing the building envelope (walls, windows, roof) can all trigger compliance requirements. ADU construction always requires Title 24 compliance. Kitchen remodels that add lighting circuits have lighting efficiency requirements.

What Compliance Requires

Title 24 compliance typically requires a CF1R (Certificate of Compliance) prepared by a certified HERS rater, and may require CF2R (Installation Certificate) and CF3R (Field Verification) documentation. These add $500–$2,000 to residential project costs but are required as part of a complete permit submittal.

Working with an Experienced Contractor

Experienced California contractors build Title 24 compliance into their scope and pricing as a matter of course. Missing Title 24 documentation is one of the most common reasons permit submittals are rejected at plan check. We submit complete, compliant packages on every project we permit.
