Commercial HVAC Permit

Online Applications now available

Please Note:

  • PLI has modified permit application requirements. Construction drawings will be required for Commercial HVAC permits, unless the work is exempt as noted in this Bulletin. This Bulletin also outlines additional required documentation including, but not limited to, documentation of Energy Code compliance. Our Commercial HVAC Application has been modified to reflect this change, see below for a link.
  • HVAC drawings will no longer be reviewed with Building permits. If these were previously submitted with a building permit, they will need to be resubmitted at time of electrical permit application.
  • All new HVAC Permits will be assigned to inspection by a City Inspector.
  • Any existing Permits that had required Third Party Agency Inspection, will be required to be completed by the Third Party Inspector.

How to Get a Commercial HVAC Permit

Commercial HVAC permits are required to perform HVAC work for all structures other than single or two-family dwellings. This includes multifamily buildings with three or more units and mixed-use buildings with residential units and commercial spaces.

Please refer to list of work not requiring an HVAC permit, if work to be performed is not included on this list, an HVAC permit is required before work begins.

All work under a Commerical HVAC permit must be performed by an HVAC contractor registered with the City of Pittsburgh.

Please be aware that Commercial Cooking Hoods and associated Suppression Systems are processed under separate permits.

Items Required for Permit

  • A completed Commercial HVAC Application signed by an authorized agent of the owner of the property.  An application completed by a Pittsburgh Licensed HVAC contractor will be required prior to issuance of the permit.
  • Two sets of drawings prepared and sealed by PA licensed Engineer/Architect.
  • An approved HVAC permit may only be issued if the related building permit is in approved or issued status.
