What Can a Handyman Do in Saint Louis in Saint Louis County, Missouri?

Missouri does not issue a single statewide “general contractor” or “handyman” license. Instead, contractor licensing (and most trade licensing) is handled at the city/county level, meaning a handyman can often operate without a state contractor license—but must comply with local contractor registrations, permits, and any required electrical/plumbing/HVAC credentials where the job is located.

In MO, jobs under $Unlimited typically don't require a contractor license. Always verify with your local licensing authority.

✅ What You Can Do Without a License

Painting (interior/exterior) where no lead-abatement certification is required; follow EPA RRP rules for pre-1978 homes when applicable
Drywall patching and minor repairs (non-structural)
Trim/carpentry repairs (baseboards, door casing, minor cabinetry repairs)
Replacing door hardware (locks/knobs), installing shelves, curtain rods, and TV mounts
Minor caulking/grouting, tile repairs that do not alter waterproofing assemblies or plumbing
Assembling prefabricated furniture/sheds/playsets (non-permanent, non-structural foundations)
Gutter cleaning and minor soffit/fascia repairs (no structural roof framing changes)
Like-for-like fixture swaps only where the local inspector permits it (e.g., replacing a faucet or light fixture) — BUT permits/licensed trades are often required in the City of St. Louis depending on scope

⚠️ What Requires a License

Pulling electrical permits and performing electrical work beyond minor like-for-like device/fixture replacement (especially any panel work, new circuits, rewiring) — typically requires a locally licensed electrician in the City/metro municipalities
Plumbing system alterations (new lines, moving fixtures, water heater replacement in many jurisdictions, sewer work) — typically requires a locally licensed plumber and permits/inspections
HVAC/mechanical system installation or replacement (furnaces, AC condensers, coil changes, duct modifications) — commonly requires mechanical permits; refrigerant handling requires EPA Section 608 certification
Gas piping installation/alteration (CSST, black iron, appliance gas hookups beyond simple connections) — commonly requires permitted work by qualified trades
Structural work (load-bearing walls, beams, foundation repairs, framing changes) — generally requires building permits and plan review
Roof replacement (not just minor repair) — commonly permitted and may require contractor registration depending on municipality
Work in regulated environments (lead-based paint in pre-1978 housing where RRP applies; asbestos-containing materials) — requires federal/state compliance and may require specialty licensing/abatement contractors

State Licensing Rules (MO)

Even without a state contractor license, you may still need: (1) local contractor registration/business license, (2) building/electrical/plumbing/mechanical permits, and (3) trade credentials for regulated trades (typically licensed/registered by the local authority having jurisdiction).

Required. City of St. Louis Business License (Business License / Business Registration handled through the Collector of Revenue / License Collector functions)

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

A license/registration is your legal authority to operate as a business or contractor/trade in a jurisdiction; a permit is job-specific approval to perform regulated construction work at a particular address with inspections. In Missouri (and especially the St. Louis area), even if the state does not license handymen/GCs, the City and municipalities can still require permits and may restrict who can pull them (often only licensed trades/registered contractors).

Important Notes for Saint Louis in Saint Louis County, Missouri Handymen

Insurance: Many municipalities/clients require general liability insurance; common small-contractor policies are $1,000,000 per occurrence / $2,000,000 aggregate (market pricing varies). Workers’ comp is required if you have employees.
Metro-area reality: The biggest compliance risk in St. Louis is assuming a rule in one municipality applies everywhere—many licensing/permit rules are municipality-specific.
Permits/inspections: If you perform work that should have been permitted, it can lead to stop-work orders, double permit fees, and problems for the homeowner at resale.
Advertising/contracting: Use written scopes, change orders, and clarify whether you or the owner is responsible for permits and inspections (some jurisdictions will not allow an unlicensed person to pull certain permits).
Sales tax: If you sell materials to customers (rather than being reimbursed), confirm Missouri sales/use tax responsibilities with the Missouri DOR.
