Colorado is Fast-Tracking Heavy Fines for Mobile Home Park Water Violations

What This Bill Actually Does

Back in 2023, Colorado passed a massive baseline law (HB23-1257) requiring the state to test the drinking water in every single mobile home park by July 1, 2028. It was a good start, but regulators quickly realized that finding bad water and actually getting it fixed are two entirely different battles. Enter HB26-1145, which is essentially an enforcement upgrade designed to cut through red tape and stop bad actors from stalling.

Under the original law, the state could step in for direct, acute health and safety hazards. This new bill expands that authority significantly. It allows regulators to demand cleanups for welfare-related water quality violations. The bill specifically redefines "remediation" to mean resolving issues so the water is completely "safe and healthy to drink." It is no longer just about whether the water will immediately make someone sick; it is about whether it is fundamentally usable for daily life. Furthermore, if a park owner tries to hide the test results from their residents, the Colorado Department of Public Health and Environment (CDPHE) can now issue a direct legal order forcing the owner to certify they have notified everyone living in the park.

But the real meat of the bill is how it changes the penalty phase. Currently, park owners can drag out the process by requesting administrative hearings to fight fines. This bill entirely strips away that stalling tactic. Under HB26-1145, a park owner is no longer entitled to an administrative hearing to contest a civil penalty. If the state slaps them with a fine, it is considered a final agency action. They either pay it or they have to sue the state in actual court. And those fines add up fast: regulators can levy a $10,000 base civil penalty, plus an additional $5,000 for every 30-day period the violation continues. The legislation also explicitly prohibits park owners from passing the cost of these water fixes onto the residents, unless the owner happens to live in the park too.

What It Means for You

If you live in a mobile home park, this bill is a massive, direct layer of consumer protection for your tap water and your wallet. We have all heard the horror stories—communities forced to rely on bottled water for months, brown water coming out of the tap, or boil notices that seem to last forever. This legislation shifts the power dynamic. If your park's water fails the state's testing, the owner cannot just quietly bury the report. The state can now legally force the park owner to prove they have handed over the resident notice certifications. You have a fundamental right to know exactly what is in the glass of water you hand to your kids.

Financially, the biggest win for residents is the strict prohibition on pass-through costs. Fixing a community well, overhauling park pipes, or installing commercial filtration systems is wildly expensive. Without this bill, a park owner could conceivably divide that $100,000 repair bill by 50 lots and suddenly hike everyone's rent to cover their own deferred maintenance. HB26-1145 explicitly states that owners cannot impose the cost of compliance on park residents. Your lot rent should not randomly spike just because the owner finally had to fix a toxic well. The only exception is if the park owner actually lives in the park alongside you, in which case they can bear their individual resident share of the costs.

Whether you rent a lot or own your mobile home outright, here is what you should do to protect yourself:

• Check your park's testing timeline: The state is mandated to test all parks by July 1, 2028. Ask your park management if your community has been tested yet, and request the results.
• Document your water quality: If you are experiencing prolonged water issues, take photos and keep a log. The new "welfare-related" standard means the water simply needs to be unhealthy or unusable to trigger state action.
• Contact the committee: This bill is currently sitting in the House Transportation, Housing & Local Government Committee. If you have lived through a water crisis in your park, email the committee members this week. Real stories move the needle faster than lobbyists do.

What It Means for Your Business

If you own, manage, or invest in mobile home parks in Colorado, the regulatory landscape is rapidly shifting from the "assessment phase" to "aggressive enforcement." The state isn't just testing the water anymore; they are actively removing your ability to drag out the appeals process if problems are found. Under HB26-1145, if you get hit with a civil penalty for non-compliance, you completely lose your right to an administrative hearing. It becomes a final agency action immediately. If you want to fight the fine, your only option is to file for judicial review in a real trial court, which means significantly higher legal fees, public court records, and a lot less time to negotiate a settlement with regulators.

You need to pay incredibly close attention to the financial math here. The penalties are steep and unforgiving. You face up to $10,000 per violation, plus an ongoing $5,000 penalty for every 30-day period you remain out of compliance. Even more critically, the law absolutely forbids you from passing these capital expenditure costs onto your tenants. If an aging well needs a massive overhaul, that capital comes straight out of your operating margin or reserves. On the flip side, if you are a commercial plumber, a civil engineer, or a water remediation contractor, this bill is a massive, state-mandated lead generation tool. Park owners are going to be under extreme duress to fix infrastructure quickly to avoid that $5,000 monthly bleeding. They will need reliable contractors who can deploy immediately.

Business owners and investors need to act defensively right now to protect their assets:

• Audit your water infrastructure this week: Do not wait for the state's 2028 testing deadline to roll around. Get a private, independent test done now so you aren't forced into a rushed, premium-priced remediation plan when the state knocks on your door.
• Review your compliance paperwork: The state can now issue legal orders and penalties specifically for failing to certify that you notified residents about test results. Get your paper trail organized and standardized immediately.
• Update your pro forma and capital reserves: Remove any financial assumptions that water compliance costs can be subsidized by future lot rent increases. You need to secure separate financing or dedicated capital reserves for potential water infrastructure upgrades today.

Follow the Money

From a state taxpayer perspective, this bill is remarkably efficient—it is essentially free to operate. According to the official fiscal note from Legislative Council Staff, the current Mobile Home Park Water Quality program already has a healthy baseline budget of $4.5 million and 16.3 full-time employees. Because the infrastructure for testing is already in place, HB26-1145 requires zero new state appropriations. The Colorado Department of Public Health and Environment (CDPHE) and the state judicial system will absorb any extra enforcement workload within their existing daily operations.

Where the money really moves is in the penalty phase. The state expects to see new, albeit minimal, state revenue generated from the heavy fines levied against non-compliant park owners. These civil penalties—the $10,000 base fines and the $5,000 monthly kickers—will be credited directly to the state's Mobile Home Park Water Quality Fund to help sustain the program. It is worth noting that because these penalties and any subsequent court filing fees are considered state revenue, they are subject to TABOR (the Taxpayer's Bill of Rights) limits. However, the state assumes most park owners will ultimately comply, meaning the actual cash flow from fines will not drastically alter the state budget.

Where This Bill Stands

HB26-1145 was officially introduced in the House on February 4, 2026, by prime sponsors Rep. Elizabeth Velasco, Rep. Jacque Phillips, and Sen. Lisa Cutter. It has been formally assigned to the House Transportation, Housing & Local Government Committee, which will be its first major test.

Given the current legislative climate at the Capitol—which has heavily favored tenant protections, affordable housing preservation, and mobile home resident rights over the past few sessions—this bill has a very strong trajectory. The fact that it requires zero new taxpayer dollars makes it an easy "yes" for budget-conscious lawmakers. Keep an eye out for the upcoming committee hearing schedule; that is exactly where industry lobbyists representing park owners and real estate trusts will likely make their stand. They will almost certainly try to amend the bill to soften the $5,000 monthly penalty timelines or fight to reinstate the administrative hearing process. If it clears the House and Senate without major watering down, the law will take effect in August 2026.
