SoCalGas - Multi-Family Residential Rebate Program

SoCalGas offers rebates for installing energy-efficient natural gas equipment in multi-family residential buildings, including water heaters (up to $1,500 for tankless models in individual units or up to $575 for storage models), boilers, ovens, and other systems. To apply, you must own or manage a property served by SoCalGas, purchase qualifying equipment, and submit a completed application with proof of purchase and a recent SoCalGas bill to multifamilyrebates@socalgas.com or the mailing address provided. Check your rebate status online or by calling 1-888-431-2226.

This program allows you to serve multi-family property owners and managers by installing SoCalGas-approved, energy-efficient natural gas equipment that qualifies for substantial rebates—ranging from $400 for patio heaters to $1,500 for in-dwelling tankless water heaters. Your customers must provide you with a recent SoCalGas bill matching the installation address and account, and you should ensure all equipment meets the efficiency specifications listed in the 2026 Multifamily Rebate Application before installation to guarantee rebate eligibility. The property owner or authorized agent submits the application with itemized paid invoices and proof of purchase.

SoCalGas administers this rebate program to reduce natural gas consumption in multi-family residential properties (apartment/condominium complexes and mobile home parks) by incentivizing efficient water heaters, boilers, ovens, fireplace inserts, and building controls. Rebates are tiered by equipment type and efficiency level—for example, storage water heaters receive up to $6 per mBtu, tankless water heaters up to $12 per mBtu, and in-dwelling tankless models up to $1,500 flat. Applications are processed by the multifamily rebates team; applicants submit documentation including property account verification and paid receipts to track program uptake and manage funding allocation across eligible technologies and customer segments.
