Corona specifics
Four things to know before a Corona window project.
Chapter 7A expands to High zones
The city's fire page says Corona Fire is accepting the 2025 maps without changes. Before adoption, permit applicants in the Very High zone had to comply with Chapter 7A of the 2022 California Building Code, and after adoption applicants in both the Very High and High zones must meet the same standard. The page lists council hearings in May and June 2025 and an expected July 2025 adoption, and doesn't confirm that adoption happened.
The WUI rule covers new construction
The city's wildland-urban interface page says all new construction within a WUI Fire Area shall meet Chapter 7A requirements, and offers an address lookup tool and map. It says nothing specific about glazing or window replacement, so we don't claim replacements trigger it.
No window rebate from the city's utility
Corona's Department of Water and Power residential rebates page lists items such as clothes washers, toilets, irrigation controls and turf replacement, but no window rebate. We confirmed that only on the residential page, so check with the city before assuming one.
The Circle and its historic district
Corona is known as the Circle City for its one-mile circular original townsite, and the city's municipal code authorizes a historic resource program. City Park sits in the Corona Historic District. We found no Mills Act or window-specific rules.

Permits & fire rules
What to confirm before ordering
We couldn't read the municipal code on permits, so we don't state an exemption.
Permits
A search extract says installing windows is an example of permitted work, but we found no Corona window handout or confirmed exemption, so ask the Building Division whether your project needs a permit.
- Ask your installer to confirm in writing whether a permit is needed
- Ask what energy documentation the city expects
- Ask whether your home is in the historic Circle area
Fire zones
Use the city's fire area address lookup to see whether you're in a High or Very High zone, and ask Corona Fire (951-736-2220) whether Chapter 7A glazing applies to a replacement. The page doesn't say, so only the state code can answer.
- Check your address on the city's lookup tool
- Plan for seller disclosure if you're selling in a mapped zone
