Minnesota Plumbing Contractor Surety Bonds

Why is a Minnesota plumbing bond required?

The Minnesota Department of Labor and Industry Construction Codes and Licensing Division requires all plumbing contractors to post a $25,000 contractor bond before beginning any plumbing work. This bond ensures that the principals (plumbing contractors) abide by all applicable laws and regulations for their industry, including the Minnesota Plumbing Code. These bonds offer the obligee (Minnesota Construction Codes and Licensing Division) and consumers protection in the event that the principal practices negligence or causes physical or financial harm.

How much does a $25,000 plumbing bond cost?

SuretyBonds.com can issue a $25,000 Minnesota contractor license bond instantly online for a $125 premium on a one-year term. However, applicants can save time and money by purchasing their bond for multiple-year terms with a 25% discount. This would mean that two years of bond coverage would cost $218.75 in place of two annual $125 payments.

Once you have purchased your Minnesota plumbing bond, the original bond documents will be sent to your address on file via trackable shipping. These original documents must be filed with the obligee to fulfill the surety bond licensing requirement.

You can find more information on additional contractor bonds required in Minnesota on our MN contractor bond page.
