What are some building setback legalities?

Building setback legalities in Boulder County, Colorado, are dependent upon the zoning classification of the property and the adjacency of the road in accordance with the property, explains Boulder County. In Sonoma County, California, setbacks for parcels over 1 acre are 30 feet from the property line, notes Sonoma County.

Building setbacks are ordinances established and regulated by local municipalities, and they outline where the construction of a building can occur, explains the Legal Dictionary. They regulate property owners to keep them from crowding nearby properties, and they provide areas where utility pipes can be placed below the ground. They also protect wetlands and wildlife.
