Multifamily Affordable Solar Housing (MASH)

Important Update: Effective November 23, the MASH program in our territory will be officially closed to new applications for the waitlist. Waitlist in the MASH program has historically been maintained to ensure that there is an appropriate number of projects in the pipeline to back fill any existing projects that may withdraw or cancel. At this time, we have received sufficient amount of projects on its waitlist to close the program to new applications.

Program Overview

The Multifamily Affordable Solar Housing (MASH) Program provides up front incentives for qualifying multifamily, affordable housing buildings. In 2015, MASH received $54 million in additional funding from AB 217. Additionally, we were able to transfer $4.56 million from MASH 1.0 rollover budget.

Typically, the owner of the multifamily building will apply for the incentive to offset the cost of installing a new solar energy system for common areas and/or to reduce energy costs for low-income tenants.

Two incentive levels are available: Track 1C & 1D. Please see the table for a summary of requirements.
