Wisconsin does regulate weed-choked vacant lots, but through the noxious-weed statute and municipal codes rather than a Rock County blight ordinance. Under Wis. Stat. §66.0407 the local weed commissioner can order destruction of noxious weeds on any lot and bill the owner.
There is no countywide Rock County ordinance policing vacant lots for junk or general blight; that is municipal. What does apply statewide is Wisconsin's noxious-weed law, Wis. Stat. §66.0407, which every city, village and town administers through a weed commissioner. It requires landowners to destroy noxious weeds and lets the commissioner enter and destroy weeds on a neglected lot, charging the cost back to the owner as a special tax. Cities and villages layer their own tall-grass and property-maintenance limits on top. For a specific vacant lot, check the municipality's code and the county's shoreland/floodplain rules if the lot is near water.
Under Wis. Stat. §66.0407 the weed commissioner may destroy noxious weeds and assess the cost to the owner as a special tax on the parcel. Municipal tall-grass violations add separate fines.
