Rock County has no general dark-sky lighting ordinance, and neither does the City of Janesville. Outdoor lighting is mainly addressed through zoning conditions and shoreland standards, not a county-wide dark-sky code.
There is no county-wide dark-sky or light-pollution ordinance in Rock County, and Wisconsin sets no statewide residential lighting standard. The City of Janesville has lighting standards for commercial development's impact on nearby homes but no general dark-sky ordinance. Where lighting is controlled, it is usually through conditional-use permit conditions in zoning (requiring shielded, downcast fixtures) or through mandatory shoreland zoning that limits lighting near lakes and streams. For a routine residential yard light, expect no county dark-sky rule; a persistent glare problem is handled as a private nuisance or under any local ordinance your town or city has adopted.
With no dedicated dark-sky ordinance, enforcement is limited to zoning permit conditions or nuisance remedies rather than a fixed county fine.
