(The Center Square) – The Washington State Senate on Thursday approved a 10% cap plus the consumer price index on annual rent increases, drastically changing a House of Representatives version of the bill that had a 7% cap. Following more than 90 minutes of floor debate, Engrossed House Bill 1217 passed on a 29-20 vote. Sen. Sharon Shewmake, D-Bellingham, sponsored the amendment to increase the rent cap to 10%. The amendment narrowly passed, 25-24. EHB 1217, one of the most controversial pieces of legislation introduced this session, now heads back to the House for approval of the changes made by the Senate.
