Review Mechanical Contractor Bond Requirements
While there is no state license required for mechanical contractors, businesses must file a $25,000 mechanical contractor bond with DLI in order to contract to perform gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work.
-
The bond must be on the form approved by DLI and written by a surety company licensed to do business in Minnesota. An insurance agent can help in obtaining a bond from a licensed surety company.
-
There are additional application forms required to submit a mechanical contractor bond available in this packet.
-
The fee for filing a bond with DLI is $100 and the filing is valid for two years.
-
The renewal fee for a bond filing is $100.
-
Make sure the bond from your insurance agent is properly signed and notarized.
-
Your bond filing can be submitted online or mailed to DLI with a check payable to the State of Minnesota for the $100 fee.
In addition to filing a bond with DLI, mechanical contractors must comply with local licensing requirements.
Individuals performing mechanical work
Minnesota also has no state license requirement for individual employees of mechanical contractors. However, cities may require licensure or a competency card for workers performing mechanical work. These licenses, or “comp cards,” are not issued by DLI. Questions about individual licenses or comp cards should be directed to the city requiring them.
