Weatherization Assistance Programs Available in San Francisco
Weatherization is the process of improving a home’s energy efficiency by making it more air-tight and insulated. Weatherization assistance programs in San Francisco help low-income households save money on their energy bills by providing services for free or at a significantly reduced cost. As a single parent struggling to keep the lights on, or as a senior on a fixed income, these programs can make a meaningful difference in your monthly budget.
Since its inception in 1976, the U.S. Department of Energy’s Weatherization Assistance Program (WAP) has helped improve the lives of more than 7.2 million families nationwide. Here are the primary weatherization assistance programs available in San Francisco:
Low-Income Home Energy Assistance Program (LIHEAP)
LIHEAP is a federally funded program that provides financial assistance to low-income households to help them pay for their energy bills. In San Francisco, the Human Services Agency administers the program locally. LIHEAP covers financial assistance for home heating and cooling costs, weatherization improvements, and energy-related home repairs. To qualify, your household income must generally fall at or below 200% of the federal poverty level, or 60% of the state median income.
California Climate Credit
The California Climate Credit is a bi-annual credit applied directly to electricity bills across the state. Administered by the California Public Utilities Commission (CPUC), the credit helps offset the costs of the state’s cap-and-trade program aimed at reducing carbon emissions. In San Francisco, the credit is applied automatically to eligible households’ energy bills—no application is required. The credit also provides funding for broader energy efficiency programs throughout the state.
San Francisco Energy Watch
San Francisco Energy Watch is a program administered by the San Francisco Public Utilities Commission (SFPUC) that provides free energy-efficient upgrades to eligible low-income households. The program offers a variety of services including LED lighting installation, water-saving fixtures, and replacement of outdated appliances with Energy Star-rated models. As a renter in a drafty apartment, you could qualify for free upgrades that reduce both your electricity and water usage without any out-of-pocket cost.

California’s Low-Income Weatherization Program (LIWP)
In addition to the federal WAP, the California Department of Community Services and Development (CSD) operates the Low-Income Weatherization Program (LIWP). This state-funded initiative provides free solar photovoltaic systems and energy efficiency upgrades to qualifying low-income households. LIWP is part of California Climate Investments, a statewide plan that puts billions of cap-and-trade dollars to work reducing greenhouse gas emissions while prioritizing disadvantaged communities. Your household’s annual pretax income must be less than 60% of the state median income to qualify.
Energy Efficiency Programs That Lower Your Monthly Bills
Energy efficiency programs in San Francisco are designed to help low-income households reduce their energy usage and save money on their energy bills. While weatherization focuses on physical improvements to your home’s structure, energy efficiency programs take a broader approach that includes education, behavioral changes, and appliance upgrades.
LIHEAP Energy Education Workshops
Beyond bill payment assistance, LIHEAP also provides free energy education workshops for eligible households. These workshops cover practical energy-saving tips, weatherization techniques you can implement yourself, and home safety best practices. As a homeowner looking to stretch every dollar, these workshops can teach you simple strategies—like sealing air leaks around windows and adjusting your thermostat schedule—that compound into meaningful savings over time.
California Energy Efficiency Fund
The California Climate Credit also channels funding into dedicated energy efficiency programs. In San Francisco, the Energy Efficiency Fund oversees local programs that provide funding for energy efficiency upgrades and educational initiatives. These programs work alongside San Francisco’s broader utility assistance programs to ensure that low-income families have multiple pathways to reduce their energy burden.
“Households that adopt energy-efficient technologies can save up to 30% annually on energy bills. Weatherization isn’t just about comfort—it’s about long-term financial stability for families who need it most.”

4 Rebates and Incentives for San Francisco Homeowners
Rebates and incentives are financial rewards offered to households that implement energy-efficient upgrades in their homes. These programs put money back in your pocket while encouraging sustainable home improvements. Here are the key rebate and incentive programs available in San Francisco:
1. California Alternate Rates for Energy (CARE)
CARE provides discounted energy rates to eligible low-income households—typically a 30% or more reduction on your monthly energy bill. The program also offers free energy-efficient upgrades to eligible families. To qualify, your household must meet specific income guidelines based on the number of people in your household and total income. You can apply by contacting your energy provider or visiting the CPUC website.
2. SFPUC Energy Efficiency Rebates
The San Francisco Public Utilities Commission offers rebates for energy-efficient appliances and home upgrades. These rebates can be applied toward insulation improvements, HVAC system upgrades, water heater replacements, and lighting retrofits. You must be a residential customer of the SFPUC to qualify. You can find a complete list of eligible improvements and rebate amounts on the SFPUC website.
3. San Francisco Solar Incentives
San Francisco offers a range of incentives for households that install solar panels, including rebates, federal tax credits, and low-interest financing.

Energy Audits and Assessments: Finding Where Your Home Loses Energy
Audits and assessments are professional services that help households identify specific areas where they can improve their home’s energy efficiency. Before any weatherization work begins, an energy auditor will perform a comprehensive evaluation of your home—including a blower-door test to measure air infiltration, an inspection of insulation levels, and an analysis of your heating and cooling systems.
Home Energy Score
The Home Energy Score is a rating system developed by the U.S. Department of Energy to evaluate the energy efficiency of a home on a scale of 1 to 10, with 10 being the most efficient. The assessment takes into account your home’s heating and cooling systems, insulation quality, air sealing, as well as the home’s size, age, and geographic location.
The primary goal of the Home Energy Score is to inform homeowners and prospective buyers about how energy-efficient their home truly is and to pinpoint areas where improvements can deliver the greatest energy savings. In many areas, home energy scores are used in conjunction with weatherization programs, which provide funding and resources to help homeowners implement the recommended efficiency improvements. By identifying the areas of your home that need the most attention, the Home Energy Score helps guide weatherization efforts to achieve maximum cost reductions.
A Home Energy Score assessment can reveal actionable improvements such as adding attic insulation, sealing air leaks around windows and doors, upgrading to a high-efficiency furnace, or replacing single-pane windows. To get a Home Energy Score assessment for your San Francisco home, visit the Home Energy Score website or contact your local utility assistance program provider.

To be eligible for SFPUC energy efficiency rebates, you must be a current residential customer of the SFPUC. The rebate amounts vary depending on the type of upgrade, but they can significantly offset the upfront cost of energy-efficient improvements. For example, multifamily property owners with 5 or more units can receive up to $750 per unit in rebates through Energy Upgrade California in San Francisco. Individual homeowners should check the SFPUC website for the most current rebate offerings and application procedures.
San Francisco Solar Incentives: Going Solar on a Budget
For San Francisco residents interested in harnessing solar energy, there are attractive incentives available through both local and federal programs. The SFPUC offers incentives for residential and commercial solar panel installations, with amounts that vary based on system size, roof orientation, and other installation factors.
California’s Net Energy Metering (NEM) program allows solar panel owners to receive credit on their utility bills for excess electricity they send back to the grid. Combined with the federal Investment Tax Credit (ITC), which provides a significant percentage credit on the cost of your solar system, going solar in San Francisco has never been more financially accessible—especially for households already enrolled in weatherization assistance programs in San Francisco.
