Handyman License Requirements in Saint Louis, MO

By Ray Duke, Founder of Bulletproof Handyman · Last reviewed February 2026

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.

⚠️ What Requires a Contractor License

The following work requires a state-issued contractor license in MO. Performing this work without a license exposes you to fines, stop-work orders, and civil liability:

• 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 Contractor Licensing Law (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).

Special Jurisdictions & Zones

The following special jurisdictions may have separate licensing requirements:

• Scott Air Force Base (near Belleville/Shiloh, IL) — If you are not bidding federal work, the more practical route is often to subcontract under an established federal prime contractor already authorized to work on base.
• Gateway Arch National Park (National Park Service unit, downtown St. Louis) — Even small maintenance scopes are usually procured through federal contracting channels or performed by existing service contractors.
• City of St. Louis Local Historic Districts (e.g., Lafayette Square, Soulard, Central West End local historic areas) — If you change windows/doors, repair brick, replace roof materials, or modify porches/fences, check historic requirements before ordering materials.

City Business License — Saint Louis

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

Permit vs. Contractor License — The Legal 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).

Business Entity Registration (MO)

To operate legally you must register your business. LLC filing fee in MO: $50 (one-time).

Compliance Notes for Saint Louis in Saint Louis County, Missouri

• 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.

1. Step 1: Form your business entity (LLC recommended) with the Missouri Secretary of State ($50 filing).
2. Step 2: Obtain a City of St. Louis business license if you are operating in the City (fee varies by classification and gross receipts/payroll; confirm with Collector of Revenue).
