Green Bay, Wisconsin, is a mid-sized city with a robust housing stock ranging from historic homes on the east side and downtown to newer developments in the Howard, Suamico, and Allouez areas. The city experiences harsh winters, with temperatures frequently dropping below freezing from November through March. This climate creates steady demand for plumbing services related to frozen pipes, water heater failures, and furnace-related plumbing issues. The market includes both residential and commercial clients, with a significant number of multi-unit apartment buildings and condominiums near Lambeau Field and the university areas. Competition is moderate—there are several well-established local plumbing companies such as Pete's Plumbing, Bayside Plumbing, and Ace Plumbing, but many operate with limited online presence. Newer plumbers who invest in local SEO and digital marketing can carve out a strong position by targeting underserved neighborhoods like the Broadway Historic District, the Astor neighborhood, and the growing suburban communities to the south and west. The COVID-19 pandemic also drove increased interest in home renovations, including bathroom remodels and basement waterproofing, which remains a consistent revenue stream.
Wisconsin requires all plumbers to be licensed through the Wisconsin Department of Safety and Professional Services (DSPS). The most common license for a sole proprietor or small business is the Master Plumber License (license type PM). To qualify, you must have at least five years of experience as a journeyman plumber (three years if you have an associate degree), pass the Wisconsin Master Plumber exam, and submit proof of liability insurance. For new contractors, you may also need a Registered Master Plumber license if you intend to work directly with homeowners. If you plan to hire employees, you must register as a Plumbing Contractor (license type PC) with DSPS after obtaining your Master license.
Green Bay city and Brown County require plumbing permits for almost all work, including new installations, alterations, and repairs. The City of Green Bay Building Inspection Department issues permits for work within city limits; for unincorporated areas or towns like Ashwaubenon, De Pere, or Bellevue, permits are handled by Brown County or the respective village/town. You must pull a permit before starting any job and schedule inspections at rough-in and final stages. Failure to pull permits can result in fines and stop-work orders.
You need to register your business with the Wisconsin Department of Financial Institutions (DFI) if you choose a structure like LLC or corporation. A sole proprietorship can use your personal name, but a DBA (doing business as) must be filed with the Brown County Clerk of Courts. You also need a federal Employer Identification Number (EIN) from the IRS, even if you are a sole proprietor, to open business bank accounts and file taxes.
Wisconsin law requires plumbers to carry general liability insurance (minimum $500,000) and workers' compensation insurance if you have employees. Many commercial clients and property managers also require you to be bonded. The Green Bay Builders Exchange often requires proof of insurance and bonding for contractor listings.
