Summary

Harrison County's Unified Development Code sets district-by-district yard minimums in Table 416, and adds a stricter buffer rule at § 416.07: any non-residential use next to a residential district must keep a side yard of at least 25 feet and a rear yard of at least 50 feet, both jumping to 100 feet, screened by a 6-foot fence, when the adjoining use is light industrial.

These county ordinances apply to unincorporated areas of Harrison County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Side - The side yard building setback line on each side of the lot shall be not less than twenty-five (25) feet as measured from the side lot line to the nearest building or structure except in instances where a light industrial use abuts a residential district, in which case a minimum side yard of one hundred (100) feet shall be provided on the side adjacent to the residential district. Such space will remain open and unoccupied by any other structure or uses and will be screened from residential district by a fence not less than six (6) feet in height. Rear - The rear yard building setback line shall be not less than fifty (50) feet except in instances where light industrial use abuts a residential district, in which case a rear yard of not less than one-hundred (100) feet shall be provided.

Full Breakdown

01 of the Unified Development Code assigns the "area, yard, height and other dimensional requirements" for every zoning district to Table 416, which lists separate front, rear, and side yard figures for each classification from the 15-acre Agricultural A-1 district down through the R-3 multi-household category. " Both jump to a full 100 feet when the adjoining use is specifically light industrial, and that expanded strip must stay "open and unoccupied by any other structure or uses" and be screened from the residential side by a fence at least six feet high.

Table 416 separately flags that ordinary residential front and side yard setbacks "may be required to be up to 40' on a functionally classified road", a stricter figure than the base district minimum for lots fronting a busier road. 04: a 15-foot side yard setback along the abutting public street. All of these distances are measured to the nearest building or accessory structure, not to open decks, driveways, or fences, which the Code addresses separately under §§ 822 and 828.

Violations & Fines

Building inside a required yard setback is a zoning violation the Zoning Officer can address with a written notice or a formal Cease and Desist Order under § 1409.01. A knowing, willful violation is a misdemeanor under § 1409.03, punishable by a fine of up to $100 per conviction, with every day the encroaching structure remains counted as a separate offense.

Frequently Asked Questions

What is the minimum side yard setback when a business is built next to a home in Harrison County?
UDC § 416.07 requires at least 25 feet from the side lot line to the nearest building, rising to 100 feet if the adjoining use is light industrial. That expanded buffer must stay empty of other structures and be screened by a fence at least 6 feet high.
What is the rear yard setback rule for non-residential uses next to residential property?
Section 416.07 sets a minimum of 50 feet from the rear lot line, increasing to 100 feet where a light industrial use abuts a residential district, though no rear yard is required at all where that industrial use backs onto a railroad spur.
Where do I find the setback for my own residential zoning district?
Table 416, adopted under UDC § 416.01, lists separate front, rear, and side yard minimums for each district, from Agricultural A-1 through the R-1, R-2, and R-3 residential categories, plus a note that front and side yards can be required up to 40 feet on a functionally classified road.
What about setbacks on corner lots?
UDC § 416.04 requires a 15-foot side yard setback measured along the public street a corner lot abuts, on top of whatever front and rear yard figures Table 416 assigns to the lot's zoning district: a rule adopted specifically to keep sightlines clear at intersections.
