A Development Code (also known as a Zoning Code, Zoning Ordinance, or Land Use Code) is a set of regulations and guidelines that govern the physical development of land. It outlines the rules and standards for land use, zoning, building design, construction, and other aspects of urban and rural development. Development codes also classify land into zones (also known as districts). These zones define land by use type (e.g., residential, commercial, industrial, agriculture). By classifying land by these broad categories, the City can assign specific development standards (e.g., lot size, building height, yard setbacks), to maintain compatible and consistent development within a given area. These standards emphasize the importance of the interaction between building facades, site plans, public spaces, and neighboring development.

As required by State law, the Arroyo Grande Development Code includes allowed land uses and development standards linked to and consistent with the General Plan goals, policies, and programs. It is through this link that the land uses, and development standards establish the basis for project approval and the entitlement process. The Development Code regulates, among many things, allowed land uses, density, lot size, building height, yard setback, parking, landscaping, and signs.

Over time, it is essential that municipalities revisit the standards and regulations in development codes. By revising and updating its Development Code, Arroyo Grande will ensure its regulations reflect community values and expectations.
