Title 24 reports in Glendale.
CF1R and NRCC energy compliance for Glendale projects: new homes, ADUs, additions, remodels and commercial work. From $200, back in two business days, with plan-check corrections included.
Glendale is in Climate Zone 9, LA Basin and San Fernando Valley
Hot dry summers, cool nights, mild winters. The busiest residential zone in California.
Where Glendale projects usually lose margin: Attic and duct performance dominate. Radiant barrier and a cool roof are cheap margin here.
Every compliance run for a Glendale project uses the CEC weather file for Burbank, the reference station for Zone 9. That file, not the address, is what the energy budget is calculated against, which is why getting the zone right matters more than anything else about location.
