  • Excavation of basement
  • Debris/soil removed from basement
  • Rear and side windows closed up
  • Interior completely gutted and many small rooms created.
  • No permits for construction work

 

Please note that you will need to make separate complaints about different items, e.g. “excavation of basement” or “removal of front yard” There is a character limit so it will need to be short.
