Summary
Fargo deleted the IRC mandate for sprinklers in one- and two-family homes, but still requires them in certain townhouses with long private access roads.
R309.1 Townhouse automatic sprinkler systems. An automatic residential sprinkler system shall be installed in townhouses which are located on a private street or private fire department access road that is required to be greater than 150 feet in length as required by Section 503 of the International Fire Code.

Section R318.3.2 is hereby amended to read as follows:
R318.3.2 Floor elevations at other exterior doors. Exterior doors other than the required egress door shall be provided with landings or floors not more than 8 inches below the top of the threshold.
Exception: An exterior landing or floor is not required at the exterior doorway where a stairway with a total rise of less than 30 inches (762 mm) is located on the exterior side of the door, provided that the door does not swing over the stairway.

Full Breakdown
Fargo adopted the International Residential Code but amended it locally: Section R309.2, the one- and two-family dwelling sprinkler mandate, is deleted outright, so single-family and duplex homes built to the residential code carry no sprinkler requirement. Townhouses are treated differently. R309.1 requires an automatic residential sprinkler system when the townhouse sits on a private street or private fire department access road exceeding 150 feet, tracking the fire-lane length trigger in IFC Section 503.
Violations & Fines
Building without required sprinklers in a covered townhouse blocks occupancy sign-off; the inspections office withholds the certificate of occupancy until the system passes inspection.
