This ordinance amends the zoning code such that bulk plane regulations apply to all detached single-unit homes in all R-series residential zone districts (R-1, R-1A, R-1B, R-1C, R-2, R-2A, R 3, and R-3A). A bulk plane standard adds a diagonal limit of construction for the purpose of limiting the mass and scale of a home and accessory structures. By adding a diagonal limit, a structure, or the upper story of a structure, is required to increase its distance from the property line as it gets taller. Bulk plane currently applies to single-unit homes only in the R-1C and R-3 zone districts, and this ordinance expands the applicability of bulk plane.
