California Meter Compliance Program

While submetering is widely accepted in California, the regulatory environment is complex with implications for property owners and managers.

Due to previous industry standards, it is estimated that as many as 75% of all existing meter installations in California may be in violation of one or more Weights and Measures and/or state law requirements. Many property managers have already received notices of violations, which can leave them vulnerable to sanctions, fines, and additional levels of enforcement including “cease billing” notices.

The only way to avoid these fines and notices is to identify violations and correct them before Weights and Measures does.

ista can help.
