Low-Income Weatherization Program – Large Multi-Family (CA)

The LIWP-LMF program is designed to provide energy efficiency retrofit/weatherization services to large multifamily dwellings in disadvantaged communities or DAC’s, as defined by the California Environmental Protection Agency, to deliver significant and aggressive greenhouse gas reductions.

AEA is the Service Provider working directly with the California Department of Community Services Development (CSD) to implement the program throughout the DACs. AEA works directly with property owners to identify opportunities for energy efficiency, solar photovoltaic (PV) systems, and solar hot water systems. Property owners who participate in the program can receive financial incentives for installing these measures in their buildings. AEA will provide property owners with procurement assistance, on-site energy assessments, energy modeling and customized work scope development, construction management assistance, and post-construction quality assurance, verification, and training support.

Funds for these projects were awarded to AEA by CSD under the Low-Income Weatherization Program (LIWP), which was funded $75 million in Climate Investments Program proceeds in the State’s 2014-15 budget.


Listed below are the main program criteria a project must satisfy in order to participate in the LIWP-LMF program.

  • All of the properties participating in the LIWP must be located within the DACs. To see if your property is located within a DAC, please click here.
  • Under the LIWP-LMF Program, property owners will participate in cost sharing, or co-investment, for energy audits, general weatherization, renewables and for any “buy down” of measures which will be a portion of the total weatherization cost. In addition to the program’s financial incentives, property owners may also leverage funds from other utility rebates, such as the Multifamily Affordable Solar Housing (MASH) Program, to apply towards their co-investment requirements.


  • Energy Efficiency Upgrades, including central systems, common areas, and dwelling-units.
  • Solar Water Heating installation
  • Solar PV installation
