To open a coffee shop in Wisconsin, you’ll need a Restaurant or Retail Food Establishment license from DATCP (processed by your local agent health department) plus a Wisconsin seller’s permit from the Department of Revenue. Start by confirming zoning/occupancy with your municipality, then submit a plan review before any build-out: include your menu (flag items like cold brew/nitro), scaled floor plan, equipment spec sheets (NSF/ANSI), plumbing schematics (indirect drains, ASSE 1022 backflow on espresso/ice), finish schedule, and intended sanitation methods (three-compartment sink or commercial dishwasher). Licensure is risk- and seating-based; if you only sell sealed, shelf-stable items, you may qualify as prepackaged retail, but milk espresso drinks, open TCS pastries, or sandwich prep push you into full restaurant licensing. At least one Certified Food Protection Manager (ANSI-accredited) must be on staff; the PIC on duty must demonstrate Food Code knowledge. Expect a pre-opening inspection verifying hand sinks, adequate refrigeration (≤41°F), sanitizer strengths, thermometers/logs, and safe gas cylinder storage for nitro systems. Cold brew often requires written controls (time/temperature parameters and shelf-life) and, in some jurisdictions, a variance/HACCP. Secure fire/building approvals, grease interceptor determinations, and water/sewer clearances (well/septic need documentation). Licenses renew annually (state cycle typically July 1–June 30). Collect/remit sales tax on prepared beverages. Apply early—plan reviews can take weeks.
