Your project in Green Bay
Use this Green Bay project checklist to prepare an inquiry: approximate deck dimensions, the height at the house door, access for excavation and whether existing framing will remain. Include the property’s municipality, not just the mailing town, so permit questions go to the right office.
Permits and the property
Green Bay lists decks as requiring a permit. Its non-structural decking-board replacement category is listed separately as not requiring one. Confirm the scope with city inspections before starting.

Built around Wisconsin conditions
Under Wisconsin’s prescriptive deck appendix, footings must bear on solid ground below frost penetration or at least 48 inches below finished grade, whichever is deeper. This is not a claim that every site has exactly 48 inches of frost. Soil, the house foundation and the proposed loads can require additional design.
Snow drift and sliding snow are explicitly identified as potential concentrated loads. Ask your contractor or designer to check the actual layout rather than treating a basic deck table as approval for a roof, hot tub or heavy planter.
