What is a Title 24 / CF1R report?

Title 24 Part 6 is California's Building Energy Efficiency Standards. A CF1R is the Certificate of Compliance document we produce to prove your project meets those standards. It is required by most California jurisdictions before a building permit will be issued.

How long does a Title 24 report take?

Most Single Family CF1R reports are delivered within 48 hours of receiving complete plans. Multifamily timelines depend on unit count, typically 3 to 7 business days.

Do you serve all of California?

Yes. We prepare CF1R reports for projects in every California county, including Los Angeles, Orange, San Diego, the Bay Area, Sacramento, Central Valley, and the Inland Empire.

Is CHEERS registration included?

Yes. CHEERS registration is included in every Title 24 report we deliver.
