What Can a Handyman Do in Madison, Wisconsin?

In Wisconsin, there is no single statewide "general contractor" license for typical handyman/general building work, but you must comply with state trade credentialing (especially electrical and plumbing) and local permitting. Most handyman businesses also need Wisconsin Dwelling Contractor (qualifier) credentialing if they contract for 1–2 family dwelling work that requires building permits, plus a Dwelling Contractor certification for the business—this is where many small contractors get tripped up. Madison (City of Madison) primarily regulates through building permits/inspections and zoning (home occupation), not a universal citywide "business license" for all handymen.

✅ What You Can Do Without a License

• Painting (interior/exterior) where no lead-safe RRP trigger applies and no historic-review restrictions apply
• Minor drywall patching and trim repairs (non-structural)
• Basic carpentry like replacing baseboards, interior doors/knobs, and cabinet hardware
• Installing shelves, towel bars, blinds/curtain rods, and TV mounts (avoiding concealed wiring/plumbing)
• Minor caulking/grouting and tile repair that does not involve plumbing system alterations
• Assembling furniture and installing prefabricated closet systems
• Replacing faucets/showerheads or toilets ONLY if local rules allow minor like-for-like fixture swaps without re-piping and you obtain required permits if triggered
• Deck staining/sealing and small non-structural exterior repairs (permits may still be required depending on scope)

⚠️ What Requires a License

• Electrical work such as new circuits, panel/service work, rewiring, adding outlets, hardwired fixtures, and most troubleshooting/repairs (state electrical credentials + permits)
• Plumbing system installation/alteration (water heaters, new supply/drain lines, moving fixtures, gas piping/fuel gas work) (licensed plumber + permits)
• HVAC/Refrigeration work on systems and refrigerants (state credentials and often EPA requirements for refrigerants; permits may apply)
• Structural work that requires a building permit (framing changes, load-bearing wall changes, egress window cut-ins, many deck builds) — typically triggers permitting and may trigger Dwelling Contractor/DCQ requirements if you are the contractor on 1–2 family dwelling permit work
• Roofing/siding/window replacements when permits are required or when working in historic districts requiring additional approvals
• Lead-based paint work in pre-1978 housing that triggers EPA RRP requirements (federal certification/lead-safe practices)

State Licensing Rules (WI)

Even if you call yourself a handyman, you generally cannot perform electrical work (beyond very limited owner/utility exceptions) or plumbing work without the appropriate state credential and permits. Many municipalities require permits for water heaters, structural repairs, decks, egress windows, and most work beyond cosmetic repairs. If you are acting as the contractor on 1–2 family dwelling projects that require permits, you should expect Dwelling Contractor-related credentialing to apply.

Not required at the city level.

Permit vs. Contractor License — What's the Difference?

A license/certification is permission for a person or business to perform/contract for regulated work (especially electrical/plumbing and certain dwelling-contractor roles). A permit is job-specific approval from the local building department to perform work at a specific address; permits trigger inspections. Even if you do not need a state credential for a task, you may still need a city permit before starting the work.

Important Notes for Madison, Wisconsin Handymen

• Insurance: Expect customers/property managers to require general liability (commonly $1,000,000 per occurrence) and, if you have employees, workers’ compensation. If you do dwelling contractor certification, confirm any insurance requirements tied to that credential.
• Common compliance mistake: Doing "small" electrical or plumbing work without the proper state credential and permit—this is a top enforcement issue and can void insurance coverage after a loss.
• Permits: Madison inspections can require scheduling lead time; build that into bids. Always confirm whether the property is in a local historic district before quoting exterior changes.
• Taxes: If you sell materials as retail or provide taxable items, register with WI DOR; also ensure you handle withholding/unemployment if hiring.
