House Bill 1160, introduced in Washington on February 5, 2025, aims to address the ongoing housing crisis by mandating increased residential unit development in cities based on their population size. The bill seeks to promote affordable housing and higher density living, particularly near major transit stops, as a strategy to combat housing shortages and improve accessibility.

The bill outlines specific requirements for cities with varying populations. For cities with populations between 25,000 and 75,000, it mandates the development of at least two units per lot in predominantly residential zones. This requirement increases to four units per lot if the location is within a quarter-mile of a major transit stop or if at least one unit is designated as affordable housing. In larger cities with populations over 75,000, the bill stipulates a minimum of four units per lot, escalating to six units under similar conditions as those for smaller cities.

For smaller cities with populations under 25,000, the bill allows for the development of at least two units per lot, provided they are within a contiguous urban growth area of a larger city. To qualify for these additional units, developers must commit to maintaining a specified number of units as affordable housing for at least 50 years, adhering to local government affordability and income eligibility standards.

The introduction of House Bill 1160 has sparked discussions among lawmakers and community stakeholders. Proponents argue that the bill is a necessary step toward alleviating the housing crisis, particularly in urban areas where demand for affordable housing is high. Critics, however, express concerns about potential overdevelopment and the impact on community character, as well as the feasibility of maintaining affordability over the long term.

The implications of this bill are significant, as it could reshape housing policies across Washington state. Experts suggest that if passed, it may lead to increased housing availability and affordability, potentially easing the burden on low- and middle-income families. However, the bill's success will depend on local governments' ability to implement and enforce the new requirements effectively.

As the legislative process unfolds, stakeholders will be closely monitoring the bill's progress and its potential impact on Washington's housing landscape. The next steps will involve committee reviews and discussions, where amendments may be proposed to address concerns raised during initial debates.
