Fishers, IN Building Setbacks & Zoning: Setback Rules (2026)

16 (Setback Standards) applies to all zoning districts. Sec. 2 establishes three setback types, front, side, and rear, each measured perpendicular from the corresponding property line, and measured from the edge of the existing or proposed right-of-way (per the Thoroughfare Plan), whichever is greater. The specific minimum setback figures, however, live in Chapter 3 (Zoning Districts) and differ by district, so a single citywide number does not exist; you must identify the parcel's district to get its required front/side/rear setbacks. Several standards in Sec. 2 apply regardless of district: Other Setbacks (C) require primary and accessory structures to be set back from the top of bank of any watercourse by at least one-quarter the height of the structure plus the width of the eaves plus 5 feet, and to be at least 25 feet from the edge of the 100-year floodplain.

Commercial Setbacks (D) impose, where a side or rear yard abuts a residential district, a side yard of at least 30 feet and a rear yard of 50 feet (the rear may hold parking if a 30-foot buffer yard is kept), and require a 50-foot setback for frontage roads or drives paralleling a street. An infill lot in a substantially built-out subdivision may use the average setback as defined in Chapter 12 (Sec. 2(B)(4)). 20.
