Certificate of occupancy
A certificate of occupancy certifies that a building complies with the applicable building and safety codes and may lawfully be occupied.
It is the document that says the work is done and the building is fit for what it is being used for.
When one is required#
New construction. Nobody may lawfully occupy a new building until it is issued.
Substantial renovation, depending on scope and on the city's rules.
A change of use. Converting a single-family house to a duplex, a commercial building to residential, a garage to a dwelling unit. The building may be unchanged physically and the use is different, which is what triggers it.
Requirements vary between Minnesota cities, so the local building department is the authority rather than any general statement.
Occupying without one#
Not lawful where one is required, and the consequences are broader than a fine.
Enforcement, including orders to vacate.
Insurance problems. An insurer discovering that a building was occupied without a required certificate has grounds to dispute a claim, which surfaces at exactly the wrong moment.
A sale problem. A missing certificate is discovered during a later transaction, and resolving it retrospectively means bringing work up to current code — frequently a much larger job than complying at the time would have been.
That last one is the common case. Unpermitted conversions get discovered when somebody tries to sell.
Temporary certificates#
Where minor items remain outstanding and none affect safety, cities may issue a temporary certificate permitting occupancy while the work is finished.
It carries an expiry date and conditions. It is a bridge, not an alternative, and letting one lapse without obtaining the final certificate creates the same problem as never having had one.
The Minneapolis TISH link#
A Certificate of Occupancy exempts a newly built property from needing a Truth in Sale of Housing evaluation when it is sold.
The logic is straightforward: the city has already certified that the building complies, so a point-of-sale evaluation adds nothing.
The parallel exemption is a Certificate of Code Compliance, issued after a property is brought out of condemnation and good for up to one year.
For anyone rehabilitating distressed property#
The certificate is the finish line, and planning backwards from it is what keeps a project on track.
Permits pulled properly, inspections passed at each stage, and the final certificate issued. Work done without permits on a distressed property is cheaper and faster right up to the point of sale, where it becomes the reason the sale does not close.
