9 form-based codes are municipal development regulations that go beyond the conventional zoning controls of segregating and regulating land use types and defining building envelopes by setback requirements and height limits. Form-based codes instead address the details of relationships between buildings and the public realm of the street, the form and mass of buildings in relation to one another, and the scale and type of streets and blocks. Form-based codes are based on specific urban design outcomes desired by the community, that may be identified through an inclusive, design-focused public participation process. The regulations in form-based codes are applied to property through "regulating plans" that map the community with geographic designations that are based on the scale, character, intensity, and form of development rather than differences in land uses. (Crawford)

11 form-based codes are a type of development regulation whose intent is to create a predictable public realm through the physical definition of urban form. (Duany) A technique for regulating development to achieve a specific urban form. Form-based codes create a predictable public realm by regulation of physical form primarily (and land use secondarily) according to the timeless principles of traditional urbanism. (Ferrell, Parolek, Price, Dover et al)
