Missouri Contractor License Bond Requirements

Verified August 12, 2026 against primary sources from the Missouri Revisor of Statutes and the Division of Professional Registration. Requirements are subject to current state statutes and agency rules, which change without notice. Confirm the figure that applies to you before you file.

Does Missouri require a contractor license bond?

No, not at the state level. No state contractor licensing board. The Missouri Division of Professional Registration operates an Office of Statewide Electrical Contractors; everything else is city and county. Missouri issues no state general contractor licence, and no state licence for plumbing, HVAC, roofing or residential building. Those are municipal. The single state-level construction licence is the statewide electrical contractor licence under RSMo 324.900 to 324.945.

What Missouri jurisdictions actually require

Amounts are set by ordinance rather than negotiated, the surety has to be authorized to do business in the state, and a lapsed bond or certificate suspends the license automatically. Confirm the current figure with the issuing department before you file.

What the statewide electrical contractor licence actually asks for

• Proof of liability insurance of $500,000, and a bond posted with each political subdivision where you will perform work, in the amount that subdivision requires. RSMo 324.920.1(1).
• A standardized, nationally accredited electrical assessment examination created and administered by a third party, at your cost.
• Experience, by one of four routes: 12,000 verifiable practical hours installing equipment and wiring; 10,000 hours plus a journeyman certificate from a US Department of Labor approved apprenticeship; 8,000 hours plus an associate's degree from a state-accredited programme; or 4,000 hours supervising installation plus a four-year electrical engineering degree.
• A grandfather route for holders of a local electrical contractor or master electrician licence, needing a passed NEC-based exam from an independent testing agency, plus either 12,000 hours or six of the previous eight years licensed by a Missouri subdivision that examines, plus proof the local licence was current and not under discipline.
• One statewide licence holder at supervisory level per firm. A firm engaging in electrical contracting must employ at least one, and a statewide licensed electrical contractor may represent only one firm at a time.

Where the requirement actually sits in Missouri

Because the requirement is municipal, a licence in Kansas City authorises nothing in St. Louis, and a bond filed with one city satisfies no other. A contractor working across the state applies separately in every jurisdiction, and carries a separate bond for each that requires one. Confirm the current amount and the accepted bond form with each building or business licence department directly, because these change without any state-level announcement.

Three things the statewide licence does not do

• It does not free you from local bonds. Read 324.920.1(1) again: posting the bond each subdivision requires is a condition of the state licence itself. The statewide licence removes local exams, not local bonds.
• It does not change permits or inspections. Under 324.925.3 a subdivision may still enforce its codes, adopt an NEC-based electrical code, issue permits, inspect your work, require a business licence, and license electricians where the licence rests on experience and a nationally accredited exam. The state issues no permits and inspects nothing.
• It is not always required. Under 324.920.4, you do not need a statewide licence to work in a subdivision that requires no local licence, or in one whose local licence you already hold. It is a portability instrument, and it earns its keep when you work across several jurisdictions.

What this means if you build in Missouri

Missouri splits into two conversations and the second is the bigger one. On licensing, there is no state screen at all outside electrical, so nothing filters the contractors you compete against or the subs you take on, and checking certificates falls entirely to you. If you do electrical work across jurisdictions, the statewide licence is worth having, and note what it commits you to: $500,000 of liability cover and a bond in every political subdivision you work in. That is a multi-jurisdiction bond programme, not a single filing, and it is exactly the kind of thing worth consolidating with one agency rather than buying city by city. On bonding generally, the absence of a state licence bond says nothing about contract bonds. Missouri public work still requires bid, performance and payment bonds, underwritten off your financial statements, working capital and backlog rather than off any licence. A contractor who reads no state licence required as no bonding required finds out otherwise on the first public bid, and building capacity takes quarters, not days.

What a Missouri license bond costs

You do not pay the face amount of the bond. You pay a premium, which is a percentage of it, and that percentage is set by underwriting - primarily your personal credit, how long you have been in business, and your financial position. A contractor with strong credit pays a small fraction of the bond amount. A contractor with credit problems pays more, and sometimes needs a market built for that situation, which we have.

A license bond is not a contract bond

This is the distinction that costs Missouri contractors work. A license bond is what the state or the city requires before it will let you operate. It is a fixed amount, it renews annually, and it protects the public. It says nothing about whether you can bond a job.

A performance bond is different. That is job-specific, written at the full contract value, and it is what an owner requires before awarding you the work. Contractors who assume their license bond makes them "bonded" find out otherwise the first time they try to bid public work.

The two are connected in one direction that matters: the financial file that gets you a license bond easily is the same file a surety underwriter reads when you ask for a performance bond. Building it properly now is what makes the bigger bond reachable later. See how contractors qualify for bonds and how a bond program gets built.

A license bond is also not insurance. It does not protect you - if a claim is paid, you reimburse the surety. See surety bonds versus insurance.

Missouri contractor license bond FAQ

Does Missouri require a contractor license bond?

Not for general contracting. Missouri issues no state general contractor licence, so there is no state licence bond. But Missouri's one state construction licence, for electrical contractors, requires $500,000 of liability insurance and requires you to post a bond with every political subdivision you work in.

How much is a Missouri contractor license bond?

There is no statewide amount because there is no statewide requirement, and for most building contractors there is no city bond either. Cities require general liability insurance instead, commonly $1,000,000 per occurrence and $2,000,000 aggregate. The bond attaches to right-of-way work: Fort Collins requires $100,000, or $250,000 for directional boring, and Denver's paving bond is $50,000 under DRMC 49-626.

Do I need a bond to be a general contractor in Missouri?

In the jurisdictions we verified, generally no. Fort Collins requires no bond on general or specialized trade licenses, and the Pikes Peak Regional Building Department requires none either. Both require general liability insurance. Aurora is the exception we confirmed, with a $20,000 license and permit bond on some classes. Confirm with the city you are pulling the permit in.

Is a Missouri license bond the same as a performance bond?

No. A license bond is a fixed annual requirement to hold your license and it protects the public. A performance bond is job-specific, written at the full contract value, and required by the project owner before award. Holding a license bond does not mean you can bond a job.

Does a Missouri contractor license bond protect my business?

No. A surety bond protects the party the bond runs to. If a claim is paid on your bond, you reimburse the surety. Liability insurance protects your business; a bond does not.
