Pasadena specifics
Four things to know before a Pasadena window project.
A city window and door handout
The city's "Window and Door Replacement" handout (dated 2015 and 2017, so confirm it's current) asks for a site sketch, a floor plan and a table of existing and new windows, plus whether the home is in a fire zone and the glazing area, U-factor and SHGC. It says glazing that is new, replaced, relocated or resized must meet the current California Energy Code.
Landmark districts need approval
The city's historic preservation page says landmark districts require approval for exterior alterations and lists replacement of windows among the changes often reviewed. A Certificate of Appropriateness is needed before building permits for major changes, and the page says review will delay a permit by about two months. Exterior work not visible from the street is exempt.
Fire zone glazing in the handout
The handout says that in a fire zone, new, reused or relocated exterior windows must be at least dual glazed with one pane tempered. A search extract of a July 2025 council agenda says the city adopted a fire hazard severity zone map dated March 24, 2025, and a September 2025 council fact sheet confirms Very High areas within the Eaton Fire boundary.
No residential window rebate on PWP's list

Permits & historic review
What to confirm before ordering
The handout is a submittal guide and doesn't say a permit is always required, and we couldn't read the city's exemption list, so we don't claim one.
What the handout covers
It describes egress for sleeping rooms, tempered glass near doors, tubs and stairs, and fall-prevention devices for some low-sill upper-floor windows. For single-family homes and duplexes, a replacement may be the manufacturer's largest standard size that fits the existing opening without framing or stucco work.
- Enlarging an opening needs plan review
- Ask the Permit Center whether your project needs a permit
- Designated historic buildings with historic windows may be exempt from the energy requirements
Landmark districts and the Mills Act
In a landmark district, ask Design & Historic Preservation before ordering. The city says past Mills Act participants saved 20% to 75% on property taxes, about 50% on average; eligibility applies to designated properties.
- Ask whether a like-for-like replacement is a minor project
- Check your address on the city's fire zone map
