The purpose of this web page is to offer some assistance and answer some frequently asked questions by customers seeking building permits from the Buildings, Safety and Environmental Engineering Department. Please be aware that the following list of requirements and Code sections are relative only to the Building Code. Requirements by other codes (i.e., Mechanical, Electrical, Plumbing, Fire Marshal, Health, etc.) are available upon request from those divisions respectively.
The Structural Division reviews construction documents and bases compliance on the following State of Michigan Construction Codes: Refer to State Web site at www.michigan.gov
The 2015 Michigan Building Code, which includes Michigan Barrier-Free Design Rules
The 2015 Michigan Rehabilitation Code for Existing Buildings
The 2015 Michigan Energy Code
Copies of these codes can be purchased from the Buildings, Safety Engineering & Environmental Department (BSEED).
Please check the availability by contacting the cashier at (313) 224-3202.
The review of construction documents for compliance with the respective codes listed above takes about one to three business days from the time the structural plan reviewer receives the drawings and specifications for average jobs. The length of time for plan review may be longer for larger and complex projects. Please ensure that the construction documents contain all the required data listed below. This will help avoid delays and/or corrections.
