In Michigan, a certificate of occupancy is the document your local enforcing agency issues to confirm that a new, altered, or repurposed building was built according to its permit and meets the state construction code. You need one before anyone moves in or uses the space. Occupying a building without it is a misdemeanor under the Stille-DeRossett-Hale Single State Construction Code Act, and the fines accrue by the day.1Michigan Legislature. MCL – Section 125.1513
When You Need One
Three situations trigger the requirement:
- New construction. Any building constructed after the Act took effect cannot be used or occupied, even partially, until a certificate has been issued.1Michigan Legislature. MCL – Section 125.1513
- Alterations. A building altered in whole or in part cannot be used or occupied until a certificate has been issued. If the building was already in use and that use continued without interruption during the work, the existing occupancy may continue for up to 30 days after the alteration is completed without a new certificate.1Michigan Legislature. MCL – Section 125.1513
- Change of use. When an existing building shifts to a different occupancy type, such as a warehouse converting to a restaurant, you need a permit before starting the work. The altered portions must meet current accessibility requirements under the Michigan rehabilitation code, and a new certificate is required once the work passes inspection.2State of Michigan. Michigan Rehabilitation Code for Existing Buildings
The 30-day alteration grace period is one of the most misread provisions in the Act. It only applies when the building stayed occupied throughout the renovation. If the space sat vacant during construction, you cannot use it until the certificate is in hand.
The Agricultural Exemption
The Act’s definition of “building” excludes structures incidental to agricultural use of the land, as long as they are not used in retail trade. The same exclusion runs through the definition of “structure.” Because these structures fall outside the code’s reach, they do not require a permit or a certificate of occupancy. Agricultural purposes covered by the exemption include crop production, dairying, pasturage, horticulture, floriculture, viticulture, and animal and poultry husbandry.3Michigan Legislature. MCL – Section 125.1502a Once the building takes on a retail function, such as a farm stand selling to the public, the exemption falls away and the full code applies.
How to Get One
Start With the Building Permit
Before any construction or alteration begins, apply for a building permit from your local enforcing agency. That agency has 10 business days to grant or deny the permit, or 15 business days for unusually complicated projects. If it misses the deadline, the application is treated as denied so you can file an appeal.4Michigan Legislature. MCL – Section 125.1511
Who your enforcing agency is depends on where you build. Any Michigan municipality can adopt an ordinance taking over code administration within its borders. Municipalities that have not done so fall under the state Bureau of Construction Codes inside the Department of Licensing and Regulatory Affairs. Neighboring jurisdictions can also enter joint enforcement agreements.5Michigan Legislature. MCL – Section 125.1508a
Inspections During Construction
The enforcing agency inspects at multiple stages, including foundation, framing, electrical, plumbing, and mechanical. Work cannot proceed past each stage without approval.
Application, Final Inspection, and Issuance
Once the project is complete, submit a written application on the enforcing agency’s form and pay the fee. The agency then schedules a final inspection, and the law requires at least 12 hours’ advance notice to the owner or the owner’s agent before that inspection.1Michigan Legislature. MCL – Section 125.1513
If the building passes, the enforcing agency must issue the certificate within five business days of receiving the completed application and fee.1Michigan Legislature. MCL – Section 125.1513 If deficiencies are found, you correct them and schedule a re-inspection.
Fees vary by municipality. Southfield, for example, charges a $40 application fee, $100 per inspector, and $150 for the certificate itself on a change-of-occupancy inspection.6City of Southfield. Certificate of Occupancy Other cities set their own schedules, so ask your local building department for a fee list early.
Temporary Certificates
If part of the building is safe to occupy before all work is done, you can request a temporary certificate of use and occupancy. The enforcing agency may issue one for a portion of the building as long as the occupied areas will not endanger anyone’s health or safety.1Michigan Legislature. MCL – Section 125.1513 The statute does not set an expiration, so duration and conditions are left to the local agency. One practical caveat: some mortgage lenders will not close on a property with only a temporary certificate in place, or they may require funds held in escrow to cover the remaining work.
If Your Application Is Denied
You can appeal a denied certificate or a refused permit to the local construction board of appeals. Every Michigan municipality that enforces the construction code must maintain such a board, staffed by three to seven members qualified by experience or training.7Michigan Legislature. MCL – Section 125.1514
The appeal has to be in writing. The board then has 30 days to hold a hearing, issue a decision, and file it, along with a written explanation of its reasoning, with the enforcing agency. You get a copy of the decision and reasoning before it is officially filed. If the board fails to act within 30 days, the inaction counts as a denial and you can escalate to the state Construction Code Commission.7Michigan Legislature. MCL – Section 125.1514 Local board hearings are public meetings under Michigan’s Open Meetings Act.
What Happens If You Occupy Without One
Knowingly violating the construction code, including occupying a building without a certificate, is a misdemeanor. The maximum penalty per offense is a $500 fine, 90 days in jail, or both.8Michigan Legislature. MCL – Section 125.1523
“Per offense” is where the exposure grows. Each day you ignore a stop-work order counts as a separate offense, and each week you disregard any other valid order from the enforcing agency is a separate offense. Liability also reaches beyond the property owner: corporate officers, directors, employees, and even government officials responsible for issuing permits or inspecting buildings can be charged if they knowingly violate the code, conceal violations, or improperly issue or withhold a certificate.8Michigan Legislature. MCL – Section 125.1523
Municipalities that handle their own enforcement can designate violations as municipal civil infractions rather than criminal misdemeanors, and they keep the fines they collect.8Michigan Legislature. MCL – Section 125.1523 The practical result is that enforcement style varies from one city to the next. There is a civil side too: if someone is injured in a building that was never certified as safe, the absence of a certificate becomes powerful evidence in a negligence claim.
Effect on Selling the Property
A missing or expired certificate can derail a sale. Mortgage lenders routinely check that a valid certificate exists before funding a loan, and if the lender turns up municipal code violations it may refuse to close or require escrow funds to cover repairs.
Michigan’s Seller Disclosure Act does not specifically list certificate of occupancy status as a mandatory disclosure item.9Michigan Legislature. Michigan Seller Disclosure Act – Act 92 of 1993 It does require disclosure of structural modifications made without permits, and individual cities, townships, and counties can impose additional disclosure obligations. Some Michigan municipalities require a point-of-sale inspection and a fresh certificate before a residential property can change hands. Where that applies, failing to obtain the certificate before closing can delay or void the sale, so check with the local building department before you list.
