In most cases, window replacement projects that add or alter conditioned space require a Title 24 report before a permit is issued.
When it's required
If your window replacement project involves new conditioned space or changes to the envelope, HVAC, or water heating, a report is generally required. 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.
