Plan Review Information

Plan Examination 
The purpose of a plan review is to assure the construction project is designed in compliance with the code. If there are issues of noncompliance, they may be addressed during the review process. This saves the applicant time and money as it is more economical to make revisions prior to the start of construction.

Who may submit? 
Construction documents may be submitted by the owner or the owner's architect, engineer, contractor, or agent. The construction statutes or codes do not fix the responsibility for the submission of construction documents. However, the owner of the construction project has the responsibility to assure that it is done.

Is a plan review necessary? 
Plans are required for all building types, except:

  • When repair work is determined by the building official to be of a minor nature.
  • When utility structures are 200 square feet or less relative to one- and two-family dwellings.
  • When commercial utility structures are 120 square feet or less.

  • When the electrical system rating does not exceed 400 amps and the building is not over 3,500 square feet in area.

  • When the total building heating/cooling system input rating is 375,000 Btu's or less for one- and two-family dwellings (See Note).
  • When alterations and repair work is determined by the mechanical official to be of a minor nature (See Note). 
  • For business, mercantile, and storage buildings having HVAC equipment only, with one fire area and not more than 3,500 square feet (See Note). 
  • When work completed by a governmental subdivision or state agency costs less than $15,000.00 (See Note). 
    • NOTE: the above outlined exceptions to plan review requirements DO NOT apply to mechanical projects at K-12 schools or facilities licensed by the Michigan Marijuana Regulatory Agency.

Application for School Building Projects and Plan Examination

A plan review application must be submitted to the appropriate enforcing agency. Therefore, prior to applying for a plan review, it is suggested the applicant review the Statewide Jurisdiction List or for school projects, the Local School Construction Enforcement List. This information is updated regularly due to changes in code enforcement that may be conducted by either the state, county or local unit of government or due to school delegation authority.

Once the plan review is completed, the total charges will be calculated and any amount due will be billed to the applicant. When the project is approved and all fees paid, an approval letter and one (1) complete set of approved construction documents will be returned to the applicant. These documents are to be placed on the project site and made available for examination by the code inspectors.

Questions should be directed to the Bureau's construction code plan review program at 517-241-9313.
