Basically includes subdivision and zoning ordinances
Zoning regulations
What is zoning?
- The division of a municipality (or other governmental unit) into districts, and the regulation within those districts of:
- The height and bulk of buildings and other structures;
- The area of a lot which may be occupied and the size of required open spaces;
- The density of population;
- The uses of buildings and land for trade, industry, residence, or other purposes.
What special circumstances do zoning ordinances usually address?
- Conditional useszoning ordinances specify three types of permitted uses for each zone: outright uses, prohibited uses, and conditional uses. Conditional uses are uses that would not be appropriate throughout the zone, but would be beneficial to the community if their number, location, design, and relation to surrounding property were controlled.
Typical review criteria require the use be compatible with and have a minimal impact on the livability of abutting properties and the surrounding neighborhood. Examples of uses that are frequently conditional uses include churches, schools, nursing homes, fraternal organizations, public offices, etc.
- Variancesmost zoning ordinances allow deviation for some standards in limited instances. The unique conditions where variances are allowed typically include: instances where the application of the standards would cause unnecessary hardship, such as the size or topography of a lot.
- Design reviewmany communities have design review to ensure that development is consistent with the communities vision. Under design review, the design of the development, including site design, and sometimes, off-site facilities, is evaluated for compliance with requirements such as density, preservation of light and air, provision of facilities , vehicle access, open space, landscaping, and visual screening.
- Planned unit development (PUD)most communities have planned unit development ordinances. PUDs typically are applied to larger developments and are intended to allow developers flexibility in meeting standards of building siting, density, access, etc.
- Nonconforming usesall communities have uses that do not conform with zoning standards when the zoning ordinance is adopted. These uses are called nonconforming uses. Most zoning ordinances have provisions for the continuance, expansion, rebuilding, or discontinuance of nonconforming uses.
- Exclusive farm use zones (EFU)all counties are required to have exclusive farm use zones. Beyond the intent of preserving agricultural land, EFU zones also allow landowners to have their property assessed at its value for agriculture. This deferral of taxation reduces the impact of property values on farmers and reduces incentives to convert farmland to urban uses.
