The term percent for art refers to a program, often a city ordinance, where a fee, usually some percentage of the project cost, is placed on large scale development projects in order to fund and install public art. The details of such programs vary from area to area. Percent for art programs are used to fund public art where private or specialized funding of public art is unavailable. Similar programs, such as "art in public places", attempt to achieve similar goals by requiring that public art be part of a project, yet they often allow developers to pay in-lieu fees to a public art fund as an alternative.
