What is Zoning? Zoning controls the use and development of land and buildings for the health, welfare and safety of the community.
What is Setback? A setback is the required minimum horizontal distance between the front, sides, and rear of the lot to the building.
What is Lot Coverage? It is the percentage of the overall area of the site that the building occupies (building area under roof at ground level/total lot area = lot coverage percentage).
Does my shed have to comply with any regulations? Yes, all structures must comply with setback requirements and sheds must meet accessory use setbacks and rear lot coverage requirements.
What is an Easement? An easement grants access to private property for utility installation and maintenance. No structure, fence or tree may be placed in an easement without the written consent of all utility companies that have the right to access an easement.
