Press Enter to show all options, press Tab go to next option

A permit is required for fire suppression systems and exhaust hood systems and plans are required to be submitted for review. 

The exhaust hood installation does not require a separate permit if it is part of a permit for an interior upfit or new construction and the hood system drawings and details were included in the building plan review. The exhaust hood installer should be listed on the building permit as a subcontractor in this case. Otherwise a separate plan review and permit will be needed. Exhaust hood installers must have a City of Rock Hill business license.

The fire suppression system for the hood does require a separate permit and plan review. Please submit drawings and details that show compliance with the SC Mechanical Code. Fire suppression system installers must have a state license from the SC State Fire Marshal's office and a City of Rock Hill business license. Use the Fire Suppression System Checklist and Exhaust Hood Plan Review Checklist to help you in preparing your plans.

Use the Fire Suppression System Checklist and Exhaust Hood Plan Review Checklist to prepare the drawings and permit application. Submit your plans to the Permit Application Center for review.  Plan review usually takes up to three business days.  Plans may be emailed, submitted online, hand delivered or mailed.
