In the zoned Billings/Yellowstone County jurisdiction, setbacks are set by district. The N1 residential district requires a front build-to zone of 8–25 feet, a 5-foot minimum side setback, and a 5-foot minimum rear setback. Rural unzoned county land has no county setback rule.
The unified Chapter 27 code assigns dimensional setbacks by zoning district within the county's 4.5-mile jurisdictional area and Billings. In the N1 neighborhood district (Table 27-300.3), the front build-to zone is 8 to 25 feet, the side setback is 5 feet minimum, the rear setback is 5 feet minimum, and accessory buildings have a 3-foot minimum rear setback (0 at an alley). Industrial districts (Sec. 27-603) require a 20-foot front and 10-foot street-side setback. Other districts have their own tables. On unincorporated county parcels in no adopted zoning district, the county sets no building setback — confirm with the City-County Planning Department which rules apply to your parcel.
Building within a required setback is a zoning violation; City-County Planning may deny zoning compliance, require a variance/administrative relief, or order correction.
