Rock County sets no general tree-trimming permit for private yards. The main county-level limit is on shoreland: near navigable water, cutting trees and shrubs is restricted under Wisconsin's NR 115 shoreland-protection standards. Elsewhere trimming is a municipal matter.
For an ordinary residential lot away from water, Rock County does not require a permit to trim your own trees; that falls to city, village or town forestry or nuisance rules. Where the county's authority is real and quotable is the shoreland buffer: under NR 115 (implemented through Rock County's shoreland zoning), routine maintenance of vegetation is allowed within 35 feet of the ordinary high water mark, but clear-cutting of trees and shrubs is not, and view/access corridors are capped. Diseased, damaged, invasive or imminently hazardous vegetation may be removed.
Shoreland vegetation violations are enforced by Rock County Planning/Zoning and DNR; unpermitted cutting can require restoration plantings plus zoning penalties.
