By the 1990s Jefferson Park's location, affordable housing, and neighborhood feel brought it back to the attention of the city and home-buyers that were tired of long commutes and wanted an urban lifestyle. Jefferson Park was made a focus neighborhood by the city of Denver and investment in infrastructure and beautification began. Eventually, Jefferson Park United Neighbors (or JPUN) was formed in 2000, after a controversial large-scale development by Sullivan-Hayes threatened to destroy the character of the neighborhood and condemn a number of homes.
