Handyman License Requirements in Platte City, MO

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

Missouri does not issue a single statewide “general contractor/handyman license.” Contractor licensing (and most trade licensing) is handled at the city/county level, so a handyman working in Platte City must focus on Platte City/Platte County rules plus state registrations for taxes and (if applicable) state-regulated trades. Even when no contractor license is required, permits are still commonly required for structural, electrical, plumbing, and HVAC work, and those permits are issued locally.

⚠️ 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:

• Electrical contracting beyond very minor like-for-like replacements—especially any new circuits, panel work, service upgrades, running new wiring, or work requiring an electrical permit/inspection (typically requires locally licensed electrician/contractor).
• Plumbing contracting beyond simple fixture swaps—any drain/vent/water line modifications, water heater replacement (often permit-triggering), sewer work, or gas piping (typically requires locally licensed plumber and permits).
• HVAC/mechanical system installation, replacement, or refrigerant-side work (typically requires mechanical licensing locally and EPA Section 608 certification for refrigerants).
• Gas piping/appliance connections where regulated (often requires a licensed plumber/mechanical contractor and permit).
• Structural work: removing load-bearing walls, framing changes, foundation work, roof structure changes, deck construction, significant window/door resizing—almost always permit-triggering and may require a registered contractor depending on AHJ.
• Projects in jurisdictions that require contractor registration/business licensing (Platte City may require both business licensing and contractor registration—verify locally).

State Contractor Licensing Law (MO)

Even without a statewide handyman license, you may still need: (1) local contractor registration/business license, (2) local building permits, and (3) state-level registrations for taxes (sales/use tax, withholding, unemployment) depending on your business.

County Requirements — Platte County

Business license: Not required at the county level.

Special Jurisdictions & Zones

The following special jurisdictions may have separate licensing requirements:

• Fort Leavenworth (U.S. Army) — approx. within 50 miles — If you are hired by a homeowner living on-base (privatized housing), there may be a separate property management approval process and access rules even if it is not a federal contract.

City Business License — Platte City

Required. City business license / occupational license (local business licensing)

Permit vs. Contractor License — The Legal Difference

A license (or contractor registration) authorizes you/your business to offer and perform work in a jurisdiction; a permit authorizes a specific scope of work at a specific address and is inspected for code compliance. In Missouri, even if there is no statewide handyman license, local permits are still required for many jobs, and trade-licensed contractors may be required by the city/county to pull those permits.

Business Entity Registration (MO)

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

Compliance Notes for Platte City, Missouri

• Insurance: Many cities require proof of general liability insurance to register as a contractor and/or to pull permits. A common small-contractor baseline is $1,000,000 per occurrence / $2,000,000 aggregate general liability (market standard; verify what Platte City requires).
• Lead paint: If you work on pre-1978 homes and disturb painted surfaces above EPA thresholds, you may need to be EPA RRP certified (federal requirement). Verify at https://www.epa.gov/lead.
• Sales tax: If you sell taxable goods/materials or provide taxable services in Missouri, you may need Missouri tax registration and to collect/remit sales/use tax (Missouri DOR).
• Common compliance mistake: Doing 'minor' electrical/plumbing without verifying the local AHJ rules—many municipalities require licensed trades for work that seems small.
• If you advertise as 'licensed,' ensure the license is real and applicable (city contractor license vs. trade license vs. business license). Misrepresentation can lead to fines and loss of registration.
