It is a violation of the building code to occupy a building that does not have a Certificate of Occupancy (CO). This document certifies that a building is fit to be occupied and that it meets the minimum requirements of the building code and the zoning regulations.
You need a CO when you are moving into a new, or renovated building.
The Building Department will conduct an inspection to determine compliance with the building code and all other applicable regulations. If the building meets the minimum requirements of the code, you will be issued a CO. The Building Department may, under special circumstances, grant a CO if weather conditions prohibit the completion of all the site work if a cash bond is posted to guarantee that the work will be done.
