Multifamily Affordable Solar Housing (MASH)

MASH (Multifamily affordable solar housing) through the California Solar Initiative began in 2009. The program is designed to lower the costs of going solar by 75 percent and has affordable housing developers quickly attempting to qualify. There has never been a better time for affordable housing to go solar and cut energy costs while supporting a system of clean and renewable energy. Incentive rates for the program are tiered based on if the power will be used to power common areas or if the clean energy will be provided directly to tenants.

Who Qualifies for California’s Multifamily Affordable Solar Housing Rebates?

Those that currently qualify for the MASH incentives are the customers within the regions of these following utility companies:

• Pacific Gas & Electric (PG&E)
• San Diego Gas & Electric (SDG&E)
• Southern California Edison (SCE)

In order for these eligible electricity customers to receive incentives through the MASH Program projects need to fall under the definition of “low-income residential housing,” which has been set forth in the Public Utility Code 2852. According to the California Public Utilities Commission (CPUC), approximately 2 million households (approximately 50 percent of low income households) in California live in multifamily dwellings that fit within the definition of “low income residential housing.”

The MASH program allows both for-profit companies and nonprofits to benefit.
