Construction bonds are surety bonds that project owners require from contractors bidding or working on construction projects. The federal legislation commonly known as the Miller Act mandates the purchase of performance and payment bonds by contractors working on federally funded projects valued at more than $100,000.
Individual states have their own versions of this legislation, often referred to as Little Miller Acts. Local jurisdictions may also require surety bonds from contractors awarded county or municipal public works projects. Increasingly, private project owners are requiring construction bonds as well.
