The Downtown Spokane Business Improvement District (BID) is a self-taxing financing mechanism providing services and improvements that enhance existing municipal services to more than 850 business owners and 350 property parcels inside the 80-block BID area. If you own a business or property in the 80 square block region of the downtown Spokane BID, you are a member of an exclusive club actively investing in making downtown Spokane the center for commerce, culture, and living in the Intermountain Northwest.
