Garage Conversion Title 24 Reports in California
Fast, accurate, permit-ready documentation prepared statewide across every California climate zone. Starting at $250.
Quick Answer
Does converting a garage to living space generally trigger Title 24 requirements? Usually, yes. Turning a garage into conditioned living space typically requires residential energy compliance documentation with the permit application. Final requirements depend on the project scope and the local building department.
What plan and equipment information is needed? Dimensioned plans of the converted area, insulation values, window and door details, and the heating, cooling and water-heating equipment that will serve the space.
What affects compliance? The climate zone for the project address, the building envelope, the windows and doors, the HVAC and water-heating equipment, and whether the prescriptive or performance compliance path is used.
What is the starting price and turnaround? Garage conversion reports start at $250. Standard turnaround is 3–5 business days after complete project information and plans are received.
What happens if the design triggers HERS measures? The report discloses them. An independent certified HERS rater performs the field testing and verification, which the rater bills separately. Apex can coordinate with or refer the project to a rater but does not perform HERS field verification.

Frequently Asked Questions
At minimum we need the site address, a dimensioned floor plan, window schedule, proposed HVAC and water heating equipment, and insulation values. The more complete your plans, the faster we can turn around your report.
We offer affordable Title 24 revisions whenever plans change before or after permit submittal. Send us the updated plans and a description of what changed, and we'll reissue a corrected report quickly.
Your completed report is delivered as a permit-submittal-ready PDF, formatted for direct upload to online permit portals or printing for in-person submittal — whichever your building department requires.
Yes. We evaluate every project against both paths and recommend whichever gets you to compliance with the least cost and complexity — sometimes prescriptive is simpler, sometimes performance modeling unlocks more design flexibility.
No. The Title 24 report (CF1R) is the energy design document submitted with your permit. HERS verification is a separate field inspection process — required only for certain compliance credits — performed by an independent certified HERS rater during construction.
