Carrollton City Zoning Code
GENERAL REGULATIONS
§ 159.020 ESTABLISHMENT OF DISTRICTS.
In order to implement the regulatory scheme of this chapter so as to achieve the objectives enumerated in § 159.002 of this chapter, the entire city is hereby divided into the following zoning districts:
District | Designation | Minimum Area* |
District | Designation | Minimum Area* |
Agricultural | A-1 | 3 acres |
Community Business | B-1 | 1 acre |
Floodplain Overlay | O-FP | None |
Highway Business | B 2 | 2 acres |
Industrial | I-1 | 5 acres |
Mobile Housing | MH-1 | 3 acres |
Multiple-Family Residence | MR-2 | 3 acres |
Single-Family Residence (Large) | SR-1 | 5 acres |
Single-Family Residence (Small) | SR 2 | 3 acres |
Two-Family Residence | MR-1 | 3 acres |
NOTES TO TABLE: * The “minimum area” requirement (which is intended to prevent spot zoning) refers to the smallest total area of contiguous parcels that can properly be given the particular district classification. The minimum area requirement is not satisfied merely because the acreage of numerous non-contiguous parcels, when aggregated, happens to equal or exceed the minimum area indicated above. | ||
