1. Number of Buildings on a Lot. No more than one principal building may be located on a lot used for a single-unit or two-unit dwelling; an accessory dwelling unit is not considered a principal building for purposes of this regulation. For other uses, more than one principal building may be located on a lot provided that each building complies with the applicable requirements of Section 156.06 (Zoning District Regulations) as though it were a principal building on an individual lot.
2. Applicability of District Regulations.
a. Applicability of Use Regulations. No building, structure, or land shall be used for any use other than a use allowed as either a permitted or special use in the zoning district in which such building, structure, or land is located. Buildings, structures, or land may also be used for a temporary use or an accessory use in accordance with the requirements of § 156.07.D (Accessory Structures and Uses) and § 156.07.E (Temporary Structures and Uses).
b. Applicability of Lot and Setback Regulations. No lot or setback shall be reduced in dimension or area below the minimum requirements of this Ordinance. Lots or setbacks created after the effective date hereof shall meet the minimum requirements established by this Ordinance. All setbacks allocated to a building shall be located on the same lot as such building.
c. Applicability of Bulk and Height Regulations. All buildings and structures erected after the effective date of this Ordinance shall meet the bulk and height requirements for the zoning district in which the structure is located. No existing structure shall be enlarged, altered, reconstructed, or relocated in such a manner that conflicts with the requirements of the zoning district in which the structure shall be located.
3. Visibility Obstruction. Nothing shall be erected, placed, or allowed to grow in a manner that will create a visibility obstruction for motorists, bicyclists, or pedestrians. No building, structure, sign, or landscape element shall exceed three feet in height within the sight triangle area formed by 25 feet along the intersecting streets, measured along the curb line, or edge of pavement where no curbs are present (see Figure 156.05.D-A. Sight Triangle).
