Mechanical Permit Inspection Requirements
Residential mechanical systems not deemed to be part of a Third-Party Inspection Program (TPIP or TPIP-R) project, typically will be inspected by DPIE building inspector(s). This includes duct rough-in, system set-up per code.
The Master HVAC installer must submit an original Third-Party certification for the following:
- System data information, distribution, zones covered.
- System startup and performance testing.
The DPIE building inspector(s) will conduct a final visual quality assurance inspection of the system for approval.
All commercial mechanical systems are required to be inspected and certified by a Maryland Registered Professional Engineer contracted by the customer. The DPIE inspector(s) will conduct a final quality assurance inspection only, and will obtain the original Third-Party certifications during the final inspection for mechanical installations which have not been deemed part of the Third-Party Inspection Program (TPIP).
Any Mechanical systems deemed part of a Third-Party Inspection Program (TPIP) project or having a total construction cost of $200,000 or more will be required to be a part of the Third-Party Inspection Program (TPIP), to include but not limited to Structural, Mechanical, Fire Protection, and Electrical inspections to be inspected and certified. Regardless of construction cost, the Building Code Official or designated representative may include or exclude a project from the TPIP due to its complexity, simplicity, or innovation.
