Zoning districts regulate land uses and development for each property in the City of Boulder. Zoning districts also designate residential, commercial, industrial, public and agricultural areas. The city's zoning code is broken into three basic parts, or modules, that specify use, density, and development requirements for each district. The combined elements of the three modules creates a zoning district.
The three zoning code modules are:
- Use - establishes the uses that are permitted, conditionally permitted and prohibited, as well as uses that may be permitted through a use review approval.
- Form - specifies the physical parameters for development, such as setbacks, building coverage, height and special building design characteristics.
- Intensity - establishes the density of development and identifies the:
- minimum lot sizes,
- minimum open space per dwelling unit,
- number of dwelling units per acre,
- minimum open space per lot or parcel, and
- floor area ratios, when applicable.
