Wisconsin's statewide Uniform Dwelling Code requires a building permit for new 1-2 family dwellings; Rock County also requires a Zoning Site Permit before construction to confirm siting.
Rock County Planning, Economic & Community Development - Zoning & Development Review ↗Zoning authority in Rock County is held by individual towns; the county provides zoning-related services on behalf of several towns, so zoning applies but varies town to town.
Rock County Planning, Economic & Community Development - Zoning & Development Review ↗Rock County Public Health reviews plans, issues permits, and inspects installations of new and replacement POWTS (private onsite wastewater treatment systems).
Rock County Public Health - Septic Systems ↗Wisconsin DSPS states that a UDC construction and erosion-control permit may be taken out by the owner who currently occupies, or will occupy, the home. The owner-builder allowance does not waive required permits; new-home plumbing and electrical work generally must be performed under the applicable licensed professionals, while an owner-occupant may install the heating system.
