Before you start digging or building, contact the Borough for the proper permits or declarations you need. Avoid Fines!
There are Land Use Permits, Conditional Use Permits, Construction Declarations, and Site Development Permits. Different uses in different zones require different permits. Find out which one you need.
Start with the Parcel Viewer to determine your Zone https://hnsak.maps.arcgis.com/apps/webappviewer/index.html?id=7d6fb8af8e9c4d7490192fb6403114a1 and then identify your use with the Zoning Use Chart: https://hainesborough.borough.codes/HBC/18.70.040
