Walworth County, WI Building Safety: Building Inspections (2026)

The Zoning Administrator's office reviews and issues (or denies) a zoning permit within 30 days of application under § 74-119(6), and that permit expires 24 months after issuance if the structure is not substantially completed, forcing a new application before work can resume. Once footings, a concrete slab, or another foundation is poured, § 74-120(a) requires the property owner to submit a foundation survey prepared by a registered Wisconsin land surveyor showing the foundation's location relative to lot lines. Construction may keep going while that survey is pending, but the survey itself is due to the zoning department within 30 days of backfilling the foundation.

If more time is needed, the applicant must submit a written request before the deadline, and the department can grant extensions in 15-day increments rather than an open-ended delay. Section 74-120(b) waives the surveyed-foundation requirement only for a structure built at least 150 feet from every property line in its zoning district; even then, the Zoning Administrator must complete a physical foundation inspection within 30 days of being notified, comparing the as-built foundation to the permitted plans. Section 74-117 separately empowers the Zoning Administrator to inspect any structure, land, or water as often as necessary to confirm compliance, and to enter premises during reasonable hours; if entry is refused, the Administrator may obtain a special inspection warrant under Wis. 122, except in emergencies where immediate entry is authorized. Every inspection finding, permit issued, and approved work item must be recorded under § 74-117(1).
