Local Zoning and Land Use Laws (Building Heights, Setbacks, and Land Coverage)
In Hillsborough, local zoning and land use laws are designed to maintain the community's character and aesthetics and ensure its residents' safety and welfare. These regulations include stipulations on building heights, setbacks, and land coverage.
- Building Heights: In Hillsborough, the maximum building height for residences is 30 feet for flat roofs and 35 feet for pitched roofs. This is measured from the average natural grade to the roof's highest point.
- Setbacks: Setbacks vary depending on the zoning district. For most residential zones, the minimum front yard setback is 25 feet, the side yard setback is 10% of the lot width (but no less than 6 feet), and the rear yard setback is 20% of the lot depth (no less than 20 feet).
- Land Coverage: Land coverage refers to the percentage of a lot that can be covered by structures, including the primary residence, garages, and other outbuildings. In Hillsborough, the maximum lot coverage ranges from 16% to 30%, depending on the size of the lot and the zoning district.
