Local Zoning and Land Use Laws (Building Heights, Setbacks, and Land Coverage)
These regulations, which govern aspects such as building heights, setbacks, and land coverage, are designed to ensure that the overall character and aesthetics of the community are maintained while also ensuring safety standards.
- Heights: Building heights are regulated to ensure that new constructions or additions do not obstruct views or create unwanted shadows. For instance, a two-story or tall building may not be permitted in certain residential areas.
- Setbacks: include front, side, and rear setbacks, which may have different requirements based on the property's zoning. This ensures adequate space between buildings, promoting privacy and reducing potential conflicts between neighbors.
- Land coverage: refers to the percentage of a lot that structures can cover, including the main home, garages, and other outbuildings. This regulation ensures sufficient open space on each property, reducing runoff and preserving the overall feel of the community.
