When you need a Addition permit in Somerset
Home additions almost always require a building permit because they change the structure, footprint, and often the electrical, plumbing, and mechanical systems. Sealed architectural plans are typically required, and additions over 500 sq ft commonly trigger zoning review for setback and lot-coverage compliance (IRC R105.1). To confirm requirements for your specific project in Somerset, WI, contact Village of Somerset Building Inspector / Zoning at (715) 247-3395. Visit: https://www.villageofsomerset.us/village-staff/.
