Developer Services
What We Do

Developer Services

The Developer Services permit process is designed to meet the special needs required for moderate to complex construction projects. The process is designed to be predictable and flexible.   A DOB Project Administrator (PA) is assigned as a single point of contact to manage the entire permit review process. The plan reviews are performed by a third party plan review firm.  This review is an additional cost to building permit fees, which is assessed based upon bids provided by our third party review firms. Applicants are required to provide 75% percent bid drawings to determine the Developer Services Fee.  Once all bids are received, the lowest bidder is selected to perform the plan review.  

New Construction Projects meeting the following criteria are required to use the Developer Services Program:

  • Buildings greater than 80 feet tall
  • Business and Mercantile projects greater than 150,000 square feet
  • Residential projects with more than 50 dwelling units
  • Gut rehab 50 units and above
  • School projects greater than 60,000 square feet.
  • Projects that require two levels of basement or deeper, and in addition utilize Earth Retention Systems (ERS)

DOB plan examiners will only perform plan reviews for Developer Services projects with the approval of the Commissioner. Drawings must be prepared, signed and electronically sealed by an Illinois licensed architect or Structural Engineer. Refer to the Developer Services Flow Chart for detailed instructions.
