Development Process

Development in Fond du Lac generally requires obtaining the appropriate permits from the city's planning and building departments. The process typically involves:

  2. Site Plan Review — For commercial and multi-family projects, submit a site plan for review
  3. Building Permit — Apply for a building permit with construction documents
  4. Inspections — Schedule required inspections during construction
