Missouri Contractor License Bonds— Municipal Only -- $1K to $25K by City

No. Missouri is one of a handful of states with no statewide general contractor license and no state-level surety bond requirement. The Missouri Division of Professional Registration confirms that contractor licensing and bonding are handled entirely at the municipal and county level. Each city and county sets its own requirements through local building, planning, or code enforcement departments. This means you must check requirements in every jurisdiction where you plan to work.

Kansas City contractors must obtain a license through the City Planning and Development department (Permits Division). Plumbing contractors are required to post a $10,000 surety bond. The application fee is $55, with a $167 license issuance fee. All contractors must carry general liability insurance with a minimum aggregate limit of $1,000,000 per occurrence listing the City of Kansas City, Missouri as additional insured. Licenses follow a four-year renewal cycle. Contact cdlicensing@kcmo.org or call (816) 513-1500 ext 1 option 2 for trade-specific bond amounts.

St. Louis has two distinct jurisdictions with separate requirements. The City of St. Louis Building Division requires electrical contractors and cable/telecommunications contractors to post a $25,000 bond. St. Louis County Department of Public Works requires mechanical contractors and electrical contractors each to post a $10,000 bond under their respective licensing codes (Chapters 1108 and 1102 SLCRO). The County bond must be filed with the County Clerk as an indemnifying bond with good and sufficient sureties.

The City of Springfield requires a $10,000 contractor license bond for licensed trades including electrical contractors, gas fitters, mechanical contractors, and plumbing contractors. The bond must be submitted through the Building and Electrical Department before the city will issue or renew a license. Bond forms must comply with city-specific language and be issued by a surety provider authorized to do business in Missouri.

Premiums depend on the bond amount and your credit score. A $10,000 bond (Kansas City plumbing, Springfield, St. Louis County) costs $100-$500 per year with good credit (700+). The $25,000 St. Louis City electrical bond costs $250-$1,250 annually. Small municipal bonds like Thayer ($1,000) cost as little as $50 per year. Applicants with credit scores below 600 can still get approved but will pay higher rates, typically 5-10% of the bond amount.

Yes. Since Missouri has no state license, each municipality operates independently. If you work in Kansas City, St. Louis City, and St. Louis County, you need separate licenses and bonds for each jurisdiction. Contractors operating across the metro areas commonly maintain three or more municipal bonds simultaneously. We can bundle multiple Missouri municipal bonds under one application to simplify the process and reduce paperwork.

A surety bond is a three-party guarantee that protects the municipality and its residents from contractor violations. If a valid claim is filed, the surety pays up to the bond amount, but you must repay the surety through indemnity. Liability insurance protects you by covering third-party property damage and bodily injury claims -- the insurer absorbs the loss. Kansas City requires both: a $10,000 plumbing bond and $1,000,000 in general liability insurance. For a full comparison, see our bond vs. insurance guide.

In municipalities that require bonds, you cannot legally pull permits or begin work without one. Kansas City, St. Louis City, St. Louis County, Springfield, Columbia, and other jurisdictions enforce their bonding requirements through their permitting systems. However, many rural areas and smaller towns have no bond requirement at all. Always verify with the local building department before starting work in any new jurisdiction.
