Definition
Official documentation from local government certifying that a building complies with codes and is safe for habitation. It's essentially a building's permission slip to exist with people inside it.
Example Usage
We can't move in until the inspector issues the certificate of occupancy, even though the house looks finished.
Origin
Emerged with building codes in the early 20th century as urban areas regulated construction safety
Fun Fact
Without a CO, you technically can't legally live in your own house, and your insurance company might refuse to cover it.
