The Oregon State Legislature has introduced House Bill 3525, aimed at enhancing the safety of drinking water in rental properties across the state. Introduced on April 16, 2025, the bill mandates that landlords conduct regular testing for contaminants in drinking water and provide clear information to tenants regarding the results.

The primary provisions of House Bill 3525 require landlords to test drinking water for coliform bacteria and other harmful contaminants. Landlords must use a standardized form to communicate whether the water has passed or failed these tests, along with details about any detected contaminants. Additionally, the bill includes a requirement for landlords to distribute educational materials about the health impacts of contaminated drinking water.

The bill is set to take effect on June 1, 2026, with a transitional period allowing landlords to conduct initial testing between January 1, 2026, and the operative date. Notably, the legislation exempts certain properties already regulated under existing water safety laws.

Debate surrounding House Bill 3525 has focused on the balance between tenant safety and the financial burden placed on landlords. Proponents argue that the bill is essential for public health, particularly in areas where water quality may be compromised. Critics, however, express concerns about the potential costs associated with compliance and the administrative burden on property owners.

The implications of this legislation are significant, as it seeks to address ongoing public health concerns related to water quality in rental housing. Experts suggest that improved testing and transparency could lead to better health outcomes for tenants, particularly vulnerable populations who may be at greater risk from contaminated water.

As the bill progresses through the legislative process, stakeholders from various sectors will continue to weigh in on its potential impact, with discussions likely to shape the final form of the legislation.
