HB 1145 Colorado House · 2026 Regular Session

Mobile Home Park Water Quality

Summary
The water quality control division (division) administers a program to test for and remediate water quality issues for mobile home parks (program). The program tests for water quality issues that pose a risk to not only health or safety but also the welfare of park residents. The act authorizes the division to require remediation of welfare-related water quality violations.     One of the requirements of the program is for the park owner to certify that the park owner has made certain water-quality-related notices to park residents. The act authorizes the division to issue an order requiring the park owner to comply with the park resident notice certification requirement.     Under the program, the park owner is prohibited from imposing the cost of compliance with certain remediation-related requirements on park residents. The act authorizes a park owner who is also a park resident to bear this cost.     The program authorizes the division to issue orders requiring the park owner to perform additional water testing, perform temporary measures necessary to address acute health risks, make additional reports to the division, create a remediation plan, implement a remediation plan, or respond to the division in connection with a remediation plan. The act clarifies that a park owner may ask for a hearing only regarding the orders that concern remediation plans.     The act also clarifies that:The division has authority to enforce the requirements of the program; andThe division has authority to issue cease-and-desist orders to address violations related to the program, regardless of whether the issues are related to water quality violations.     The act also provides that:An additional monthly penalty of up to $5,000 for a continuing violation may be imposed for the first 30 days of noncompliance; andA park owner is not entitled to an administrative hearing to contest an imposed civil penalty but may seek judicial review.(Note: This summary applies to this bill as enacted.)

What changed between versions

Rerevised Final Act · 5 edits · Apr 20, 2026
MODERATE
This bill finalizes amendments to Colorado's mobile home park water quality laws, clarifying definitions and strengthening enforcement powers. The changes ensure that water quality issues affecting household welfare are treated with the same seriousness as health risks, and they expand the Division's ability to issue orders and impose penalties for non-compliance.
Scope change
The bill's scope remains focused on mobile home parks, but the applicability of enforcement actions is broadened to include welfare-related violations that were previously less clearly defined.
DEFINITION

Added a new definition for 'Risk to Welfare,' explicitly including financial harm and water quality unsuitable for household uses like drinking or cooking.

REQUIREMENT

Clarified that park owners generally cannot pass remediation costs to residents, with a specific exception allowing owners who are also residents to bear those costs themselves.

ENFORCEMENT

Expanded the Division's authority to issue cease-and-desist orders for welfare-related violations and clarified the process for requesting administrative hearings regarding remediation plans.

Refined penalty structures to allow for additional monthly fines for continuing violations and clarified that civil penalties are final agency actions without an administrative hearing.

TECHNICAL

Removed draft-specific text, such as reading dates, committee assignments, and legislative history notes, to reflect the final enacted version of the bill.
