VANCOUVER, Wash. (AP) — Washington state lawmakers have proposed a bill to eliminate single family zoning in most cities with more than 10,000 people. KOMO-TV reported Monday that the proposal would mean local governments would be required to allow triplexes, quadplexes, townhouses, and courtyard apartments mixed into classic suburban neighborhoods. Democratic state Sen. Mona Das told KATU-TV in support of the bill that these housing types are more affordable than detached, single-dwelling houses. It is unclear how the bill is expected to impact current homeowners and property values. Republican state Sen. Hans Zeiger raised concerns about the bill in a hearing suggesting this decision should be left to local officials.
