Missouri Contractor Guide

Licensing in Missouri

The average home improvement project in Missouri runs about $31,000. That's close to the roughly $35,540 national average project cost. That puts it roughly in the middle nationally — 32nd highest of the 50 states. Missouri has no statewide contractor license, so vetting falls entirely on you: check local city or county licensing (many require it even where the state doesn't), get references, and confirm insurance directly. The most common projects here are Roof replacement, Basement remodel and Deck addition. Missouri does not require a statewide general contractor license. Verify contractor credentials with your local city or county.

Licensing body: No statewide license — local municipalities regulate

How to Vet and Pay a Contractor Safely

Get at least three written bids for anything over a couple thousand dollars — a bid that's dramatically lower than the others is a red flag, not a deal. Never pay more than 10–30% upfront (many states cap deposits by law); the rest should follow a payment schedule tied to inspected milestones, with the final payment held until the work passes a final walkthrough. Confirm the contractor carries general liability and workers' comp insurance — ask for a certificate naming you, not just their word for it — and get every change order in writing before the work starts, not after. For structural, electrical, or plumbing work, confirm your contractor is pulling the required permits — unpermitted work can complicate a future sale and may not be covered by insurance if something goes wrong.
