Los Angeles window replacement: cost, rebate and permits

Written and checked by the DuloCore research team. Last verified: November 11, 2026.

Los Angeles window replacement costs roughly $175 to $3,800 per window installed, depending mostly on the frame, according to the national price guides from HomeGuide (Feb 5, 2026) and Fixr (Jan 21, 2026) (accessed Nov 11, 2026). If LADWP supplies your electricity, it pays $2.00 per square foot of qualifying window through its Consumer Rebate Program (checked Nov 11, 2026), but only after the work has a final approved City permit.

Three things that make a Los Angeles job different

1. Your utility decides the rebate

The window rebate belongs to LADWP, and only LADWP residential customers with an active electric meter can claim it. Southern California Edison serves more than 180 cities but says its area excludes the City of Los Angeles and some other cities (SCE (accessed Nov 11, 2026)). A Los Angeles mailing address is not proof, so check who sends your electric bill. Our LADWP window rebate page explains the rules and the other programs.

2. LADBS wants a permit, even for a straight swap

Same-size, same-style replacements go through the LADBS Express Permit system; changing a window's size, type or location needs plan check at a counter. The rebate requires the final approved permit, so skipping it costs you twice. See window permits in the City of Los Angeles, including the extra review in historic districts.

3. Three climate zones and real fire country

The city runs from beach neighborhoods in climate zone 6 to the San Fernando Valley in zone 9, and its hillsides include Very High Fire Hazard Severity Zones where windows need a tempered pane. Our glass rules page covers Title 24 numbers and fire-zone glazing.

What the numbers above leave out

The price guides are national. We did not find a published Los Angeles price adjustment, so we do not apply one; expect local quotes to differ. The cost breakdown by frame material shows each source side by side, and the installer checklist helps you compare real bids.
