Does Your Building Qualify?

Each utility program has its own rules. After 500,000 fixtures we know what actually decides it, and it comes down to these four.

A Southern California multifamily or commercial property Most multifamily programs start at 5 units. Portfolios are checked property by property.
An active utility account Water, gas or electric. The customer of record on the bill is who the rebate pays.
Fixtures or systems on an older standard Toilets, aerators, lighting, water heaters and boilers all have funded replacements. EV charging and solar are funded as additions.
An owner or manager who can authorize the work One signature is the whole ask. Planet Optima files everything after that.
