Weatherization Assistance Program

​​LIWP Program, Workers installing AC, windows, heating, and door repair

CSD works with local energy services providers  throughout the state installing weatherization and energy efficiency measures for low-income homeowners and renters that qualify under the Department of Energy's Weatherization Assistance Program (WAP). Energy efficiency means using less energy which in turn can reduce utility costs. Some of the benefits of energy efficiency and weatherization include:

  • Reducing energy usage for lower utility bills 
  • Addressing health and safety issues in the home 
  • Decreases power plant emissions and air pollution

Weatherizing Your Home

Having a high energy bill is not the only indicator that you may benefit from energy efficient weatherization measures. If you notice cold drafts in your home from windows or doors, run the heater throughout the entire day in the winter, or run your air conditioner throughout the entire day in the summer, then you may benefit from having an assessment done on your home. An assessment, or energy audit, is performed by community partners in low-income households to find ways to make your home more energy efficient. Some of the energy efficiency improvements include:

  • Sealing holes and cracks around doors, windows, and pipes

  • Checking that your home is properly insulated

  • Repairing or replacing windows

  • Checking that heating and air conditioning systems run smoothly

  • Repairing or replacing water heaters

Weatherization Programs Administered by CSD

  • U.S. Department of Health and Human Services' Low-Income Home Energy Assistance Program

    • The Low-Income Home Energy Assistance Program (LIHEAP) provides assistance to eligible low-income households with the goal of managing and meeting their immediate home heating and/or cooling needs.

  • U.S. Department of Energy's Weatherization Assistance Program

    • The U.S. Department of Energy's (DOE) Weatherization Assistance Program (WAP) helps reduce energy usage and costs by providing services intended to improve energy efficiency in the homes of eligible low-income households.       

  • Low-Income Weatherization Program

    • LIWP is one of the California Climate Investments which is part of a statewide initiative that puts billions of Cap- and-Trade dollars to work reducing greenhouse gas emissions, strengthening the economy, and improving public health and the environment — particularly in disadvantaged communities. Some of the newer components of LIWP include a Community Solar Pilot and a Farmworker Energy Efficiency and Renewables Program.

Do you Qualify?

In order to receive energy efficiency or weatherization services from a local provider, your household must meet certain eligibility requirements which include income, household size, energy use, and other factors. Income sources and other factors may affect eligibility for services. Please note that our energy efficiency and weatherization programs may potentially prioritize applicants based on the greatest need, income, and households with vulnerable populations. Vulnerable populations may include the elderly, disabled, and households with young children.


Please contact your county's local energy agency for questions on eligibility.
