By the late 20th century, downtown Louisville had acquired a reputation as a place to work and visit during the week but which shuts down evenings and weekends. The first changes to this were the conversion of old warehouse and factory space to loft apartments in the late 1980s. By the late 1990s and early 2000s, new developments of luxury condominiums such as the 22-story "Waterfront Park Place", and the $30 million project "Fleur de Lis on Main", indicate increasing residential interest in Downtown Louisville. On September 9, 2013, Mayor Greg Fischer joined groundbreaking ceremonies for the second phase of "RiverPark Place", a marina apartment/condominium development covering 40 acres along River Road, with a walkway west to Waterfront Park. In 1997, the Kentucky Towers was the largest residential building in Downtown Louisville, and in 2015, just south of downtown, The 800 Apartments started undergoing a more than $10 million modernization. In 2007 Downtown Louisville became Jefferson County's tenth Multiple Listing Service zone.
