Who Needs Title 24?
Title 24 applies to the work, not to the person doing it — but what you need from a compliance report depends a great deal on your role in the project.

Homeowners
Most homeowners meet Title 24 when a building department asks for it during plan check, often on an addition, a remodel that touches windows or HVAC, or an ADU. The practical need is a correct report quickly, without having to learn the code.
Architects and designers
Designers usually need compliance confirmed while the design is still moving, so that glazing ratios and equipment selections can be adjusted before drawings are finalised rather than after a correction notice.
General contractors
Contractors are typically working to a permit deadline and need the certificates that match what will actually be installed, plus the installation and verification documents later in the build.
Builders and developers
Repeat-plan and multi-unit work benefits from consistency: the same assumptions applied across units, and reports that can be reissued as plans evolve without starting over.
