The building permit application process for commercial structures begins with submittal of an application and required documents to the Building Safety Department. The process also includes review and approval of a Zoning Certificate by the Rochester-Olmsted Planning Department, and may involve reviews by other City and County departments. Plans are reviewed for compliance with the current Minnesota State Building Code. Plan review may result in a correction letter which would require additional documents and/or clarification resubmitted in response, prior to plan approval and permit issuance.

What types of Certificates of Occupancy are available?
PERMANENT - Issued for a new building or a portion of an existing building that has changed use.
This type of certificate is issued when all the work authorized by the construction permits is complete and all required inspections have been completed and approved.
Certificate of Occupancies are valid for the life of the structure if no changes are made.
TEMPORARY - May be issued to part of a building undergoing phased construction to allow occupancy while the construction continues.
The building must be safe for non-construction personnel to occupy while the construction proceeds.
Temporary Certificate of Occupancies have very specific limitations and always include an expiration time-frame.
