Residential Zones

New residential dwelling permits require an engineer-scaled and sealed site plan. The plan can be sealed by a professional engineer, surveyor or landscape architect.

Residential zoning includes single-family dwellings, multi-family houses, apartments and condos. Residential zones are either Density Residential (DR), Resource Conservation (RC) and Residential Office (RO).


Refers to the distance that the house or structure must be from the front, sides and rear property line. Setback requirements for principal dwellings can vary based on several factors (FDP, vested plat, variance, development year, etc.). View the setback requirements:

Accessory Structure/Building

Any structure on the same property as a principal dwelling, which is incidental to the use of the principal dwelling. Accessory structures/buildings require a minimum 2.5 feet setback from the rear and side property lines. The maximum height of an accessory structure/building, without a variance, is 15 feet. A side yard placement is allowed in RC6, RC7, and RC8 zones only. Accessory structures/buildings includes, pools, sheds, pole barns, and, fire pits. Read more on accessory structures/buildings.
