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.
