Sharing Utility Bills at Your Apartment? Colorado is Setting New Rules.

What This Bill Actually Does

To understand why this bill matters, we first need to look at how older apartment buildings are built. Many multi-family properties operate on a "master meter" system, meaning the local utility company only sends one massive water, gas, or electric bill to the landlord for the entire property. To recoup those costs, landlords have historically divided that master bill among the tenants.

Last year, Colorado passed a sweeping law (HB25-1090) cracking down on hidden junk fees that landlords could charge. While great for consumer protection, it created massive legal confusion: If a landlord divides a utility bill and passes it to a tenant, is that considered a legal charge or an illegal fee? House Bill 26-1013 is the legislature's answer. It officially creates a legal safe harbor for landlords to use a Ratio Utility Billing System (RUBS). Under a RUBS setup, the landlord takes the master bill and allocates it to individual units based on a specific formula—usually taking into account the square footage of the apartment or the number of people living in it.

But the legislature isn't just handing over a blank check. To legally use RUBS, landlords must adhere to four strict consumer protection guardrails. First, the total aggregate amount billed to all tenants cannot exceed the actual bill sent by the utility company. Second, landlords are banned from tacking on any markups, surcharges, or administrative fees to the utility charges. Third—and this is a big one—landlords must legally exclude the cost of utilities used for common areas or shared facilities from the tenant's tab.

Finally, the math can no longer be a secret. The landlord must clearly and conspicuously disclose the exact method of allocation in the lease or a lease addendum. If a landlord violates any of these rules, they aren't just facing a slap on the wrist. The bill classifies these violations under the Colorado Consumer Protection Act as a deceptive trade practice, meaning landlords could face massive civil penalties brought by the Attorney General or local district attorneys.

What It Means for You

If you are a renter in a building without individual utility meters, this bill directly impacts your wallet and your rights. Up until now, if your building's master water bill went up, your landlord might have just jacked up your monthly utility fee without showing their work. Worse, you might have been unknowingly subsidizing the water used for the property's lush lawn sprinklers, or the electricity used to keep the main lobby heated to 72 degrees all winter.

This bill ensures fairness. If your landlord decides to use a ratio billing system, they must show you exactly how your share is calculated right in your lease. If they divide the bill based on your unit's square footage, it has to be written down. Even better, you are legally protected from paying for those common areas. The landlord has to mathematically separate the cost of the shared laundry room, pool, or gym before they split the rest of the bill among the tenants.

However, it's important to be honest about the downside of any ratio billing system: your bill will still fluctuate based on your neighbors' habits. If the family down the hall takes hour-long showers and drives the master water bill up, your allocated ratio will likely increase, too, even if you are actively conserving water. What this bill does is ensure the landlord isn't profiting off that transaction by sneaking in an extra $10 "utility administration fee" every month.

Here is what you should do to protect yourself right now:

• Check your current lease: Pull out your rental agreement and look for the utility section. If you are paying a flat fee or a shared fee, watch for an addendum at your next renewal that spells out the specific math they will use moving forward.
• Audit your monthly charges: Once this bill becomes law, carefully look at your monthly ledger. If you see a line item for "utility billing markup" or "admin fee," your landlord is likely out of compliance.
• Document common areas: Take note of heavy utility usage in your building's shared spaces (heated pools, massive irrigation systems). If your landlord tries to pass 100% of the property's utility bill onto the tenants, they are breaking the law.

What It Means for Your Business

If you are a property owner, real estate developer, or property manager, this bill is a critical compliance update that requires immediate attention from your operations and legal teams. Last year's crackdown on landlord fees created a chilling effect in the industry, leaving many property owners terrified that passing through legitimate utility costs would result in a lawsuit. HB26-1013 is the safe harbor you've been asking for. It explicitly protects your right to utilize a Ratio Utility Billing System (RUBS), but the compliance standards to maintain that protection are absolute.

The most urgent operational change involves third-party billing vendors. Many property management companies outsource their utility allocation to third-party software or service providers (like Conservice or RealPage), who often charge a per-door "billing fee" or "admin fee." Under this new law, you cannot pass that administrative fee on to the tenant. You can only pass through the actual, raw utility charges. If your current business model relies on tenants absorbing the cost of your billing vendor, you need to adjust your operational budgets immediately to absorb that overhead.

Furthermore, you must establish a defensible, documented formula for isolating common area utility usage. You cannot simply take the master water bill and divide it by the number of units if you have common landscaping, a shared laundry facility, or a lobby bathroom. You will need to either install sub-meters for your common areas or work with an engineer/consultant to establish a scientifically sound percentage to deduct from the master bill before running your tenant allocation ratio.

Here are the specific actions you need to take this week:

• Audit your billing software: Contact your property management software provider or third-party utility vendor immediately. Ensure their portals can strip out any automated administrative fees before generating tenant invoices.
• Calculate your common area deductions: If you don't already have a formula for deducting common area utilities, start building one. You need a defensible paper trail showing that tenants are only paying for residential usage.
• Update your lease templates: Have your legal counsel draft a new utility addendum. The law requires you to clearly and conspicuously disclose your exact allocation method (e.g., allocated by square footage, occupancy, or a hybrid). Vague language will leave you exposed to a deceptive trade practice lawsuit.

Follow the Money

From a state budget perspective, this bill is highly efficient. It requires no new state appropriations, meaning it won't cost taxpayers a dime to implement. The heavy lifting is done by clarifying existing law rather than creating a new regulatory agency to oversee utility bills.

However, there is a very real financial sting for bad actors. Because violations of this bill are tied to the Colorado Consumer Protection Act (CCPA), landlords who continue to illegally upcharge tenants or pass on common area costs can face civil penalties of up to $20,000 for each violation. That money is classified as a damage award and flows back into state coffers. Additionally, the Department of Local Affairs (DOLA), which manages various rental assistance vouchers, may experience a very minor administrative workload to update how they calculate utility allowances for voucher recipients. Overall, the financial impact is minimal for the state, but potentially severe for non-compliant property owners.

Where This Bill Stands

House Bill 26-1013 is currently moving with incredible speed and zero friction, indicating broad consensus at the Capitol. The bill cleared the House on February 18, 2026, passing its third reading without a single amendment. When a bill moves through its chamber of origin entirely unamended, it usually signals that the stakeholders—both tenant advocates and landlord associations—have already hashed out their differences behind the scenes.

As of February 19, 2026, the bill has been introduced in the Senate and assigned to the Senate Business, Labor, & Technology Committee. Given its smooth trajectory, it is highly likely to clear the Senate and head to Governor Jared Polis's desk shortly. Notably, this bill includes a safety clause. This means that instead of waiting for the standard August implementation date for new laws, this legislation will go into effect the exact moment the Governor signs it. Property managers and tenants alike should be prepared for these rules to become the law of the land by this spring.
