A form-based code is a land development regulation system that emphasizes the physical form, design, and spatial relationship of buildings and public spaces rather than strictly separating land uses through conventional zoning categories. Unlike traditional zoning ordinances, which primarily regulate property according to permitted uses such as residential, commercial, or industrial activity, form-based codes focus on how structures interact with streets, sidewalks, open space, and surrounding architecture. These regulations commonly govern elements such as building placement, height, frontage design, pedestrian orientation, streetscape character, and block configuration in order to create cohesive and walkable urban environments.
Form-based codes are frequently used in mixed-use developments, downtown revitalization projects, transit-oriented developments, and master-planned communities where planners seek to encourage predictable urban form and stronger public realm integration. The system is rooted in principles associated with New Urbanism and human-scaled design, promoting connectivity, density, and architectural continuity while allowing greater flexibility in land use over time. Developers, architects, and municipal planning agencies often employ form-based codes to guide long-term growth patterns, improve streetscape consistency, and support economically adaptable neighborhoods capable of accommodating evolving residential, commercial, and civic functions.
