When you need a Addition permit in Berlin
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 Berlin, WI, contact Building Inspection & Zoning Administration (Planning and Development Department) at (920) 361-5156.
