Rock County sets no countywide fence-height limit. General zoning inside cities (Janesville, Beloit), villages, and the unincorporated towns is municipal, so your town or city ordinance controls fence height. The county only administers shoreland, floodplain, airport-overlay, and land-division zoning.
Wisconsin land use is split: cities and villages zone inside their limits, and each unincorporated town regulates its own general zoning (fences, yards, height). Rock County's Code of Ordinances Chapter 4 covers only land division, shoreland zoning (4.2), airport-overlay (4.3), floodplain (4.4), highway-access, and addressing, not a countywide fence-height standard. A county general-zoning ordinance would not even take effect in a town until that town's board approved it under Wis. Stat. 59.69(5)(c). For a specific height cap (commonly 4 ft front, 6 ft rear in residential districts), check your town or city ordinance directly.
Enforced by your city or town, not the county. Fence-height violations are municipal zoning-code matters; typical remedy is a correction order and daily forfeitures set by local ordinance.
