Anaheim specifics
Four things to know before an Anaheim window project.
Change-outs need a permit; glass-only swaps don't
The Building Division's "When Is a Permit Required?" handout lists window and door change-outs as work that requires a permit for single-family homes, and exempts replacing panes of glass within existing frames unless tempered glass is required. A full frame replacement or retrofit needs a permit. The handout dates from 2014 and cites an older code edition, so confirm current rules.
A rebate from the city's utility
Anaheim Public Utilities' Home Incentive Program lists a window rebate of $1 per square foot, with requirements of ENERGY STAR certification, U-factor 0.28 or lower and SHGC 0.23 or lower. It's first-come, first-served until funding runs out, limited to one application per measure type per service address every five years, and needs a contractor-completed worksheet and the NFRC stickers.
Wildland-urban interface areas
According to a city environmental document, Anaheim's municipal code designates all areas east of SR-55 and south of SR-91 as wildland-urban interface, and parts of the Anaheim Hills Festival Specific Plan area are mapped Very High by Cal FIRE. The State Fire Marshal released recommended 2025 maps on March 24, 2025; we couldn't confirm the city's adoption, and we didn't verify whether Chapter 7A glazing rules apply to replacements.
Mills Act and the Anaheim Colony
Exterior alterations to Mills Act properties need approval from Historic Preservation staff through an administrative permit. A search extract of the city's historic preservation plan says inappropriate metal or vinyl windows visible from the public right-of-way in the Anaheim Colony Historic District should be replaced with windows that reproduce the historic frame and casing details.
