Hiring a Contractor

When hiring a contractor, remember that all contractors must have current registration/insurance/bond before our office will issue building permits. Electricians, Roofers and HVAC contractors must show valid business licenses to confirm their current status for business operations.

  • Call our office (815) 622-1108 to verify current status of any contractor who is bidding on your project BEFORE finalizing any business transaction.
  • The owner of the property OR contractor must come IN PERSON to obtain this permit.
  • Depending on your project, the Building Inspector might require an on-site inspection BEFORE permit is issued.

Copies of city ordinances, resident’s checklist and list of valid registered contractors can be obtained directly from our office which is located in the municipal complex at 603 West 10th Street, Rock Falls. Below is a list of current contractors registered with the city.
