Before you order
Before hiring compliance help, it makes sense to ask what your project actually needs. Whether energy documentation is part of your permit depends on what the work changes; confirm the applicable requirements and submission instructions with your building department.
Start with the general guide, or pick the project type closest to yours. Each page explains what usually triggers documentation and what to confirm locally.
Read: Do I need Title 24?Guides are general information, not a determination for your parcel. Confirm requirements with your building department.

What to send
Floor plans, elevations, sections, a window schedule, assemblies and HVAC and water-heating intentions. A combined PDF is ideal; DWG and ZIP also work. Complete inputs make rush timing possible.

Honest scope
Provisional brand. Title 24 Lab is a provisional brand name pending legal business details.
Compliance documentation records how a design meets the Energy Code. It supports a permit application; the building department decides approval.
Where the single-family form family applies, CF2R installation certificates come from installers; CF3R verification certificates come from qualified ECC-Raters when measures require them. Other classifications use their applicable form families. Neither installation certification nor verification is automatic.
