Placentia specifics
Four things to know before a Placentia window project.
A city window handout about egress
The city's one-page "Window Replacement (Residential)" handout covers emergency escape windows: 20 inches minimum clear width, 24 inches minimum clear height, 5 square feet of clear opening on the first floor and 5.7 on the second, and a sill no higher than 44 inches. It cites the 2019 building code, so it may be dated, and it doesn't say whether a permit is required.
An exempt-work page without a window exemption we could see
The city's Exceptions page lists exempt categories such as small accessory buildings, low fences, retaining walls and painting and similar finish work, and says an exemption doesn't authorize work that violates other codes. We read it through a summary and didn't see a like-for-like window exemption, so we don't claim one. Building & Safety is at 401 E. Chapman Avenue.
Newly mapped fire zones at the northern edge
The city's fire hazard page says the City Council adopted Ordinance O-2025-04 on June 17, 2025, designating fire hazard severity zones, and that the city can't lower the state's recommended levels. We read that page through a summary. A news aggregator says the zones cover about 22 parcels at the northern tip; the city page doesn't give a count, so check your address in the state viewer.
Old Town and split water service
Search extracts say Old Town Placentia, north of the BNSF railroad, is covered by an Old Town Revitalization Plan whose standards aim to preserve historic features and the original street grid; we didn't confirm it's a formal historic district or read what it says about windows. An extract of the city's new-resident guide says Golden State Water serves most residential water, with Yorba Linda Water District serving portions.

Permits & fire rules
What to confirm before ordering
We found no confirmed like-for-like exemption or over-the-counter route, so we don't claim one.
Permit steps
Ask Building & Safety whether your replacement needs a permit and what it wants to see. The two Placentia sources we found list different phone numbers, so use the number on the city's current Building & Safety page.
- Check bedroom escape sizes before you choose a window
- Ask whether the handout's 2019 code references are still current
- Ask your installer who pulls the permit
Fire zones and Old Town
If you're near the northern edge, check the state fire hazard severity zone viewer and ask what applies to a replacement; we found no city glazing rule. In Old Town, ask Planning how the Revitalization Plan standards treat exterior changes.
- Check your address in the State Fire Marshal's viewer
- Ask Planning about Old Town design standards
