Bill to Ensure Quality Drinking Water in Mobile Home Parks Passes Committee

HB26-1145 would strengthen Colorado water quality laws in mobile home parks

DENVER, CO – Today, legislation sponsored by Senator Lisa Cutter, D-Jefferson County, to improve water quality standards in mobile home parks passed the Senate Local Government and Housing Committee.

“We’ve made significant progress over the past few years to ensure that Coloradans living in mobile home parks have access to safe drinking water. However by clarifying some definitions in previous legislation, we are making it crystal clear that mobile home park residents deserve clean, safe water," Cutter said. “This legislation strengthens CDPHE's ability to implement the program to prevent water issues that can impact health and welfare. It's important to address issues before residents become sick, and this bill will do that."

HB26-1145 would strengthen water quality protections for Coloradans in mobile home parks. The bill expands the definition of “remediation” to include risks to welfare, which is defined as water quality that is not suitable for drinking, cooking, bathing, washing clothes, use with home appliances and other household uses. Negative impacts on the finances of the household are also considered a risk to welfare.

The bill would authorize the Colorado Department of Public Health and Environment (CDPHE) to enforce the requirement for mobile home park owners to notify residents of water quality test results without a complaint being filed first.

In 2023, Cutter passed the Mobile Home Park Water Quality Act to address water quality concerns in mobile home parks by establishing a water quality testing program and creating a path to remediation for mobile park owners to fix water quality issues discovered through the testing program.

According to CDPHE, as of March 1, 2026, over 600 community partners in over 200 mobile home parks had their water quality tested as a result of the framework created by the Mobile Home Park Water Quality Act. The department identified 28 parks where the water quality did not meet health-based standards. As of December 2025, 12 of those parks had remediated all issues, and the department is continuing to work with the remaining parks to address these issues.

HB26-1145 now moves to the Senate floor for further consideration. Track its progress HERE.
