An LADWP customer who adds 1,000 square feet of attic insulation above R-19 can get $750 back: $0.50 per square foot plus LADWP's extra $0.25 launch special. LADWP says attic insulation can also cut electricity bills by up to $374 a year.
So there are two kinds of savings: the rebate once, and lower bills every year. Here's how both work, from LADWP's program page checked on October 8, 2026.
How Much Is the LADWP Attic Insulation Rebate?
LADWP pays $0.50 per square foot for attic floor insulation rated above R-19, or $0.30 per square foot for R-19 or below when the attic has less than 24 inches of clearance. Every participant also gets an extra $0.25 per square foot under LADWP's extended launch special.
| Attic size | Above R-19 ($0.50 + $0.25 per sq ft) | R-19 or below ($0.30 + $0.25 per sq ft) |
|---|---|---|
| 800 sq ft | $600 | $440 |
| 1,000 sq ft | $750 | $550 |
| 1,500 sq ft | $1,125 | $825 |
These are simple multiplications of LADWP's published rates. LADWP confirms square footage through the city's ZIMAS records, and the rebate can't exceed what you paid.
How Much Can Insulation Save on Energy Bills?
LADWP says customers can reduce their electricity use and save up to $374 per year by installing attic insulation, depending on the size of the home and its location. Qualifying homes must have central, window or wall-mounted air conditioning.
So the yearly savings depend on how much you cool the house. The rebate is a one-time payment; the bill savings repeat every year. The insulation R-value chart shows ENERGY STAR's recommended attic levels by climate zone.
Who Qualifies for the LADWP Insulation Rebate?
The applicant must be an LADWP residential customer with an active electric account, or the verified property owner. Insulation must be bought and installed first, on or after September 1, 2025, and the rebate is limited to one per residence every 15 years.
LADWP's documentation list:
- A paid, itemized invoice
- An installation contract with a licensed contractor, if you didn't install it yourself
- The manufacturer's certificate of product rating
- Dated color photos of the attic, before and after, from the same angle
- A Los Angeles Building and Safety permit with "finaled" status
Applications go by mail and must be postmarked within 12 months of the purchase date (self-installed) or installation date (contractor-installed).
Is There Still a Federal Tax Credit for Insulation?
No. The federal 25C credit, which covered insulation and air sealing up to the $1,200 annual limit, ended for property placed in service after December 31, 2025, according to IRS Fact Sheet FS-2025-05. Insulation installed in 2026 gets no federal credit.
Insulation installed in 2025 can still go on the 2025 return. The guide to the federal home energy credits that ended covers the details.

Frequently Asked Questions
Are there any rebates for insulation in California in 2026?
Yes, in some utility territories. LADWP's Attic Insulation Rebate Program pays $0.50 per square foot above R-19, or $0.30 at R-19 or below, plus an extra $0.25 per square foot, as of October 8, 2026. Other utilities set their own programs, so check your address.
Can I install the insulation myself and still get the LADWP rebate?
LADWP's program allows self-installed insulation: the 12-month deadline counts from the purchase date for self-installed projects. You still need the paid invoice, the manufacturer's product rating certificate, before-and-after photos and a finaled Los Angeles Building and Safety permit.
Can I combine the LADWP insulation rebate with another utility rebate?
No. LADWP's program terms say participants can't receive more than one rebate for the same product from more than one California electric or gas utility program. The rebate is also limited to one per residence every 15 years.
