Window Replacement retrofits — replacing existing components in an existing building — can trigger Title 24 depending on scope and how much is altered.
Retrofits and Title 24
Standalone retrofits may have different compliance pathways than work tied to a larger permitted project, which almost always requires documentation. Title 24 is a statewide California energy code. Window Replacement projects follow the same statewide standards; the exact requirements depend on your project's scope and address, which we model in CEC-approved compliance software.
