LADWP Attic Insulation Rebate

Overview

The LADWP Attic Insulation Rebate Program, offered by the Los Angeles Department of Water and Power, provides financial incentives for residential customers to add or upgrade attic floor insulation. This program focuses on improving energy efficiency, particularly for reducing cooling costs in Southern California’s warm climate. It covers attic insulation projects, with rebates based on the R-value achieved. The launch special bonus is available for installations from September 1, 2025, through June 30, 2026. The program is available only in the LADWP service area within California.

How It Helps You

Adding attic insulation is one of the most effective ways to cut energy waste – heat rises in winter and cool air escapes in summer without proper insulation. LADWP estimates savings of up to $374 per year on electricity bills, depending on home size and location. This upgrade keeps your home more comfortable year-round with even temperatures and fewer hot/cold spots. It also lowers your carbon footprint by reducing energy use. Pros include significant upfront savings through rebates, quick payback, and potential stacking with federal incentives like the Inflation Reduction Act’s energy efficiency credits. Cons may include some paperwork and ensuring a qualified installer meets program rules.

Eligibility and Application

• Must be an LADWP residential customer with an active electric account or a verified property owner in the LADWP service area.
• Applies to attic floor insulation upgrades (new or added where existing is poor).
• Rebates limited to one per residence every 15 years.
• Projects must be completed on or after September 1, 2025, for eligibility (including bonus).
• Follow these steps:
  1. Hire a contractor and complete the insulation installation.
  2. Gather required documents (invoices, proof of R-value, before/after photos if needed, and application form).
  3. Submit the application online or by mail (postmarked by September 30, 2026, for bonus rebate).
  4. Wait for approval – funds are first-come, first-served.

Real-World Examples

• A typical Los Angeles home with 1,200 sq ft of attic space upgrading from low/no insulation to above R-19 could qualify for $600 standard rebate ($0.50 per sq ft), or $900 with the launch bonus ($0.75 total), plus annual savings of $200-374 on cooling bills.
• A smaller 800 sq ft attic project might earn $400-$600 back, making the upgrade affordable while improving comfort during hot summers and reducing overall energy use.
