  3. Before requesting a certificate of occupancy, please be certain that inspections in ALL disciplines have been approved.
  4. Inspections are valid for up to one year, otherwise, a re-inspection may be required.
  5. Request for Certificate of Occupancy should be submitted via email, fax, or in-person in Room 408.

Wrecking License Procedures

The City of Detroit has three wrecking licenses available. A “Class B” and a “Class C” wrecking license limits wrecking to buildings of three (3) stories in height or 35 feet. A “Class C” wrecking license is limited to residential only. The third license type is a “Class A” license that allows wrecking of all buildings.

Applicants for licensing must be approved by the Board of Examiners for Wrecking Contractors. A minimum of three years of wrecking supervisory experience (Foreman-Superintendent-Supervisor) is mandatory to qualify for a wrecking license in Detroit. Experience up to two (2) years may be extended to anyone who possesses a degree or registration as an architect or civil engineer. All employers listed on your application are required to provide the department with an Employment Affidavit.

If you were self-employed and operating your company in some other area, you can provide evidence of experience by submitting the following supporting documentation:
 

  • Copies of wrecking permits, weather cards, or other copies and permit applications signed by you and listing your company as the prime contractor.
  • Affidavits from clients or customers whose buildings you have demolished. We will not accept testimonial letters of character. This information shall be noted in the same format as the Employment Affidavit.
  • Copies of Workman's Compensation audits submitted by your firm.
  • Prior tax records.


The Board of Wrecking Contractor Examiners usually meets on the third Wednesday of every other month; however, a special meeting can be called when necessary. Only properly completed applications will be accepted for processing. All required application forms and support documentation must be secured, assembled, and completed by the applicant before submitting them to the Wrecking Board for approval. The application package must be completed and submitted at least 14 days before any scheduled board meeting, to be considered for that meeting.

The Wrecking Board's initial hearing fee is $329.00, the exam fee is $86.00, and the license fee is $302.00. All Wrecking licenses expire on December 31st of each year.

A Certificate of Acceptance, or C of A, is issued on work performed under a permit. When a contractor or homeowner completes work on a building, the work is then inspected as required by a Buildings and Safety Inspector. When the inspection has been approved, a Certificate of Acceptance can be sent to the customer through U.S. mail, email, or picked up in person at Suite 408, CAYMC. The C of A is issued for approved permitted work under all six (6) disciplines: Buildings, Electrical, Mechanical, Plumbing, Elevators, and Boilers.
