Property management company here in Austin is asking me to evaluate options for their master-metered portfolio. They've got 8 properties ranging from 24 to 180 units, all currently master-metered with landlord paying utilities. They're hemorrhaging money, especially with Austin Energy's recent rate increases on Schedule GSD-1. Question: For existing properties, is it better to install sub-meters or go with RUBS (Ratio Utility Billing System)? What's the payback period typically looking like these days?
Sub-metering vs RUBS - which works better for master-metered properties?
Vanessa, I've done this analysis for several St. Louis properties. Sub-metering gives you the most accurate billing and highest tenant acceptance, but the upfront cost is brutal - typically $800-1200 per unit installed. RUBS is much cheaper to implement ($50-100 per unit setup) but you'll get more tenant complaints and potential legal issues. In Missouri, RUBS allocation has to be "reasonable and fair" or you can get sued. What's the average unit size and current cost per unit/month?
Bill's numbers match what I'm seeing in Indianapolis. The real question is tenant turnover cost vs implementation cost. Sub-metering typically increases tenant retention because bills are fair and predictable. RUBS can drive good tenants away if not implemented carefully. IPL has been pushing time-of-use rates on master-metered properties which makes RUBS calculations even more complex. Have you looked at hybrid approaches - sub-meter electric, RUBS for water/gas?
From a legal standpoint, be very careful with RUBS in rent-controlled markets or states with strong tenant protection laws. Here in South Dakota we don't have those issues, but I've seen properties in other states get hammered with class action lawsuits over "unfair" RUBS allocations. Sub-metering eliminates that risk entirely. The payback on sub-metering is usually 18-30 months depending on utility rates and tenant usage patterns.
Thanks for the input everyone. The properties average 850 sq ft units, current utility cost running $85-120/unit/month depending on season. Austin Energy's demand charges are killing them - peak summer bills hitting $18,000/month on the 180-unit property. I'm leaning toward recommending sub-metering for the larger properties (100+ units) and RUBS for smaller ones. The per-unit installation cost drops significantly on larger projects.
Great insights Alice. I hadn't considered the rate classification angle. Austin Energy's GSD-2 rate (100-999kW) has much better demand charge structure than GSD-1 (1000kW+). If sub-metering can push the larger properties under 1000kW peak demand, that's probably $2-3K monthly savings right there. This is turning into a stronger business case than I initially calculated. Definitely recommending the full sub-meter approach now.
Vanessa, make sure to factor in the ongoing operational savings too. Master-metered properties typically waste 20-30% more energy than sub-metered ones due to tenant behavior. When people pay their own bills, they actually turn off lights and adjust thermostats. The conservation effect alone often covers the sub-metering equipment payments. Plus property values increase when utilities are tenant-paid rather than owner-paid.
One more consideration - financing options have gotten much better for sub-metering projects. Several companies now offer zero-down installations where they handle the upfront cost and get paid from the utility savings over 5-7 years. Property owner sees immediate cash flow improvement without capital investment. Worth exploring if the ownership group wants to preserve capital for other improvements.
Alice, that's exactly what we ended up doing! Found a sub-metering company that financed the whole installation. Three years later, all 8 properties are cash flow positive from day one. The 180-unit property alone is saving $180K annually in utility costs. Tenant complaints dropped to almost zero once everyone was paying their own actual usage. Best investment this property group ever made.
This is a fantastic success story Vanessa. Here in Richmond, Dominion Energy has been pushing sub-metering hard as part of their demand response programs. They're offering enhanced rebates for properties that can demonstrate 20%+ peak demand reduction. The combination of utility rebates, financing options, and operational savings makes sub-metering almost a no-brainer for any master-metered property over 50 units these days.
Vanessa, those numbers make sub-metering a no-brainer on the larger properties. Here in Tulsa, OG&E offers rebates for multi-family energy efficiency improvements including sub-metering infrastructure. Check if Austin Energy has any programs - some utilities will help fund sub-metering projects because it reduces peak demand and improves load management. The 180-unit property alone could save $200,000+ annually once sub-metered.
Rick raises a good point about utility rebates. MLGW here in Memphis has been pushing sub-metering hard to reduce system peak demand. They'll cover up to 50% of installation costs for qualified multifamily properties. The key is demonstrating load reduction during peak hours - apartments with individual control over A/C usage typically see 15-20% demand reduction. Worth checking Austin Energy's commercial programs.
Following up on Randy's comment about demand reduction - that's huge for rate classification too. Here in Virginia, Dominion Energy has different commercial rates based on peak demand levels. I've seen master-metered properties drop from Schedule GS-3 (>500kW) to GS-2 after sub-metering because tenants actually conserve when they see their own bills. The rate savings alone can justify the project before you even factor in cost recovery from tenants.
