Handyman License Requirements in Weston, MO

Missouri does not have a single statewide “general contractor license” for handymen or home-improvement contractors; licensing is primarily handled locally (city/county building departments) and by state trade boards for certain regulated trades. In Weston (Platte County), you should expect (1) a City of Weston business license and (2) local permits/inspections for many building, electrical, plumbing, and mechanical jobs. Even without a state contractor license, you generally cannot perform regulated electrical/plumbing/HVAC work without the locally required credential(s) and permits.

⚠️ 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 work that involves new circuits, panel/service upgrades, meter work, rewiring, or work requiring an electrical permit/inspection (commonly requires a locally licensed electrician)
• Plumbing beyond simple fixture swaps—running new supply/drain lines, sewer work, venting changes, water heater installs where permitted work is required (commonly requires a locally licensed plumber and a permit)
• HVAC/mechanical system replacement, new ductwork, refrigerant handling (EPA 608), gas furnace/boiler work (often requires local mechanical license + permits)
• Gas piping installation/alteration (often regulated under plumbing/mechanical licensing and requires permit/pressure test)
• Structural work: framing changes, load-bearing wall modifications, beam/post changes, roof structure repairs, new decks/porches, additions (building permit required; may require engineered plans)
• Work that triggers code-required permits/inspections (even if you personally are not “licensed” at the state level)
• Lead-based paint disturbance in pre-1978 target housing/child-occupied facilities (federal RRP compliance for paid work)
• Public works or projects requiring bonding/prevailing wage/registered contractor status per bid specs

State Contractor Licensing Law (MO)

No statewide contractor license does NOT mean “no rules.” Local permits can still be required for structural work, decks, roofs, water heaters, service upgrades, etc. Electrical, plumbing, and HVAC work are commonly restricted by local licensing even when the state does not issue a general contractor license.

Permit vs. Contractor License — The Legal Difference

A license (or local contractor/trade credential) is permission for a person/company to perform a regulated type of work; a permit is approval for a specific project at a specific address and is inspected for code compliance. In Missouri, even when there is no statewide contractor license, permits and local trade licensing can still be mandatory for many jobs.

Business Entity Registration (MO)

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

Compliance Notes for Weston, Missouri

• Insurance: General liability is commonly expected by customers and may be required for city contractor registration or pulling permits; $1,000,000 per occurrence is a common baseline in the market (verify city requirements).
• If you plan to pull permits, many AHJs require the permit applicant to be the licensed trade contractor (electrician/plumber/mechanical) rather than a general handyman.
• If you hire helpers, you may need Missouri unemployment insurance and workers’ compensation depending on payroll/industry rules; verify with the Missouri Department of Labor and Industrial Relations (DOLIR).
• Sales/use tax: Installing materials can create sales/use tax responsibilities—register with the Missouri Department of Revenue as needed.
• Always identify the Authority Having Jurisdiction (AHJ) for each job site—Weston vs unincorporated Platte County vs nearby cities—because licensing/permit rules can change by address.
