Colorado's price transparency law caps what residents can be billed at the actual utility cost, and most billing fees are not allowed. NES installs the submeters, reads them daily, and bills your residents across Denver. Get a free bid.
NES handles water, gas & electric submetering for apartment communities, condominiums, and mobile home parks across Denver and the Denver area. Install, meter reading, resident billing, and compliance, all handled in-house since 1968.
Denver's apartment market is adjusting to two new state rules in 2026, and NES bills inside both. Residents as a group can be billed no more than the property's actual utility cost, with one billing fee allowed if the lease provides for it: 2 percent of the amount billed or $10 a month, not both. Any project permitted on or after July 1, 2027 must meter every unit for water, gas, and electric. Denver Water sets the water rate and offers a commercial rebate that covers submeters, Xcel Energy sets gas and electric, and NES bills each unit at that rate.
Yes. Submetering is allowed in Denver, Colorado, with some restrictions.
Owners cannot bill residents above the utility's cost, and NES handles the requirements for you.

Administrative or billing fees on resident utility bills are generally not allowed in Colorado, and shared or common-area utility costs must be excluded from what residents are allocated rather than passed through
Where the lease provides for it, a limited billing fee is allowed on a utility the owner is billed for by a third party: 2% of the billed amount or $10 per month, but not both (C.R.S. 38-12-801(3)(a)(VI))
Colorado leases must disclose how utilities are billed to residents
For residential premises with building permits applied for on or after July 1, 2027, RUBS billing is not allowed, and each unit's gas, electric, and water service must be metered either by the utility or by a submeter (C.R.S. 6-1-737(4.5), added by HB 26-1013, effective March 26, 2026)
Electric and gas service is provided by regulated utilities such as Xcel Energy or municipal utilities, overseen by the Colorado Public Utilities Commission

Submetering in nearby Colorado cities
NES installs and runs submetering across Colorado. See the rules and results for other communities we serve.
Utility submetering puts a meter on each unit that measures and bills its water/sewer, gas, and electric use. The technology has been around since the early 1920s. NES installs the meters, reads them, pays the master-meter bill, and bills your residents, all in-house and with bilingual support.
When residents pay for what they actually use, they cut back. Most properties see 15 to 30 percent lower water use. Submetering also catches leaks early, lets you bill common-area usage accurately, and can raise the value of the property. Payback usually lands within 12 to 18 months.
Yes. Residential water, electric, and gas submetering are allowed in Colorado, and owners cannot bill residents above the actual utility cost.

For residential premises with building permits applied for on or after July 1, 2027, RUBS is not allowed and every unit must be submetered or billed directly by the utility. Electric and gas are provided by regulated utilities under the Colorado Public Utilities Commission. NES tracks every requirement so your property stays compliant.
