HVAC Plan Submittal Requirements for Commercial Projects
In order to maximize the efficiency of HVAC Inspections and reduce the need for costly required changes in the field, we have established the following requirements for HVAC plans, permits and inspections.
For multi-family residential (more than three units) and commercial HVAC work, plans prepared by a Minnesota licensed mechanical engineer must be submitted prior to or at the time of HVAC permit application. Plans will be reviewed for compliance with the Minnesota State Building Code prior to issuance of the HVAC permit.
Commercial HVAC work may not begin until the HVAC permit is issued. Inspections for commercial HVAC work will not be scheduled until the HVAC permit is issued.
Permit applications and plans are to be submitted to the permit counter in the Construction Services & Inspections office.
For permit applications submitted online via eTRAKiT, full sized plans must be submitted to the Construction Services office. Online HVAC permit applications for commercial projects will not be processed until plans are submitted. Plans uploaded via the online permit system have been determined to be illegible and inadequate for plan review so will not be accepted in lieu of full sized plans.
Any questions about HVAC plan requirements may be directed to Mike Giese at 218/730-5164.
