Submetering and Ratio Utility Billing System (RUBS) have been around in one form or another for over 40 years. For most of that time it was limited to a few small companies providing gas & electric sub-metering services to individual owner/operators of apartment buildings. This all changed in the mid nineties and was driven by three events. The first was the decision of United Dominion Realty Trust and Equity Residential Property Trust to pass water costs through to residents through a company they helped create for this purpose.
With several hundred thousand units between them their decision to pass through these costs was followed over the next few years by most of the large owner/managers. The second event was Inovonics introduction of a wireless transmitter suitable for sub-metering applications. This technology allowed the installation of non-proprietary equipment and soon became the industry standard allowing easy installation and remote reading that could be read by every company. The third event was the widespread use and acceptance of RUBS (Ratio Utility Billing System). With RUBS an owner could get many of the benefits of metered services with no equipment costs.
By the late 90′s there were over a dozen sub-metering/RUBS companies with at least 60,000 billable units and dozens more with smaller bases. By 2004 there were over 110 billing companies serving the industry. Consolidation over the last several years has reduced the number of companies providing these services to around 70. Most of the companies are little more than mom & pops without the financing or management to grow beyond their present size.
The market is huge. There are over 30,000,000 multifamily units, a similar number of manufactured home communities, 150,000 utility & water districts, 700,000 units of military housing and 15,000,000 federal facilities. Even with all the growth, it is estimated that less than 15% of the multifamily properties are presently passing all utility costs through to residents.
So far no one company has put all the pieces together and the industry is ripe for continued consolidation. The company that can install equipment efficiently, bill correctly and provide superior customer service could corner a significant share of the emerging market.
