Title 24 Energy Report (CF1R) for California Residential Permits
Need a Title 24 report, energy compliance report, or energy calculations for a residential building permit? Apex prepares permit-ready CF1R documentation statewide across every California climate zone. Starting at $195.
Quick Answer
What is a CF1R? A CF1R (Certificate of Compliance, Form 1, Residential) is the design-stage Title 24 energy compliance document submitted with a California residential permit application. It shows how the proposed envelope, HVAC, water heating and other measures meet the energy standards for the project's climate zone.
Who typically needs one? Most residential projects that add or alter conditioned space — new homes, ADUs and JADUs, room additions, garage conversions and many remodels. Your local building department decides what a specific permit requires.
What does Apex need to prepare it? The project address, dimensioned plans, a window schedule, proposed HVAC and water-heating equipment, and insulation values. Complete information speeds up the work.
How much does it start at? CF1R reports start at $195. Standard turnaround is 3–5 business days after complete project information and plans are received. Rush service may be available for an additional $100 depending on project scope and scheduling availability.
Does a CF1R replace HERS verification? No. The CF1R is the design and compliance documentation prepared before construction. When a design relies on measures that need field verification, an independent certified HERS rater performs the verification and completes the CF3R — Apex does not perform HERS field verification. Installers document installed equipment separately on CF2R forms.

About This Service
The CF1R (Certificate of Compliance, Form 1, Residential) is the design-phase Title 24 energy compliance document used for most California residential permit applications. It's what your building department reviews before issuing a permit — documenting your project's building envelope, HVAC system, water heating, and applicable mandatory measures against the energy budget for your specific climate zone.
CF1R reports apply to a wide range of residential projects: new single-family homes, ADUs and JADUs regardless of size, garage conversions to living space, room additions, and remodels or qualifying alterations that touch insulation, windows, or HVAC systems.
Every CF1R we prepare is based on your project's actual address, current plans, the applicable code cycle, and the correct climate zone for that address — not a generic template. The compliance path depends on your project: some qualifying prescriptive alterations and additions can use applicable non-registered CF1R forms, while projects requiring performance compliance or field verification follow the applicable state-approved software and registration process.

Frequently Asked Questions
A Title 24 Energy Report is a California-mandated compliance document that demonstrates a building project meets the energy efficiency standards in Title 24, Part 6 of the California Code of Regulations. It's prepared using state-approved software and is required for most building permits involving conditioned space.
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.
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.
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.
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.
