The bill creates new consumer price-disclosure requirements by adding sections to chapter 19.48 RCW and chapter 64.37 RCW. It requires that all fees or charges required to stay at a hotel or short-term rental be disclosed in the advertised, displayed, or offered room or rental rate, except for taxes and fees imposed by a government and assessment fees of a government-created special district or program. It also requires that, before a consumer reserves a stay, all government-imposed taxes and fees and assessment fees of such special districts or programs be included in the total price to be paid. The advertising scope covers any advertisement, display, or offer made before the public in Washington or from Washington before the public in any state. The bill establishes a civil penalty of up to $10,000 for each violation by a person who "knew or should have known" they advertised, displayed, or offered a rate in violation of the new sections. Enforcement may be brought by a city attorney, county prosecuting attorney, or the Washington State attorney general. The act declares an emergency and takes effect July 1, 2025. The text provided does not include statutory definitions for "hotel" or "short-term rental," does not define "taxes and fees imposed by a government" or "assessment fees of a government-created special district or program," does not specify the precise new RCW section numbers, and does not explain the legal standard for "knew or should have known" or other enforcement procedures (such as limitations or additional remedies).

If enacted, hotels and short-term rental hosts would have to show all mandatory fees in the price they advertise or display (with the exception that government taxes and special district assessment fees may be shown separately), and before a guest completes a reservation the total price must include those government-imposed taxes and assessment fees. In practice this will make advertised rates and final checkout totals clearer for guests and reduce surprise add-on charges at booking. The groups most affected are hotels and short-term rental providers, who will need to change how they advertise and present prices and ensure booking systems include government taxes and assessments in the checkout total; failure to do so can trigger enforcement by city attorneys, county prosecuting attorneys, or the state attorney general and civil penalties up to $10,000 per knowing violation. The extract does not define key terms like "hotel" or "short-term rental," what exactly counts as government-imposed taxes or special district assessment fees, or how the "knew or should have known" standard will be applied, so those implementation details and enforcement thresholds remain uncertain.
