Ohio Mechanical Code

The Ohio Mechanical Code shall apply to the installation, alterations, repairs, and replacement of mechanical systems, including equipment, appliances, fixtures, fittings and/or appurtenances, including ventilating, heating, cooling, air-conditioning and refrigeration systems, incinerators, and other energy-related systems.
A mechanical permit is required to:

  • Install new or change any part of a heating or cooling system which has ductwork or must be vented into a chimney or vent

  • Install, alter or repair gas piping (indoor or outdoor) between the meter and an appliance or a natural gas line

  • Install a wood stove or fireplace insert

A mechanical permit is not required for:

  • Portable heating appliances;

  • Portable Ventilation equipment;

  • Portable cooling units;

  • Replacement of any part which does not alter its approval or make it unsafe;

  • Portable evaporative cooler;

  • Process equipment and associated piping. For combination building services/process or power piping systems, the power or process piping located downstream of the control valve which separates the process from the building services piping is exempt from approval.

  • Self-contained refrigeration systems containing ten pounds (4.54 kg) or less of refrigerant or that are actuated by motors of one horsepower (746 W) or less.

  • Heating and cooling distribution piping installed and maintained by the public or municipal utilities.

  • Portable fuel cell appliances that are not connected to a fixed piping system and are not interconnected to a power grid.

Geothermal Heating Systems

Geothermal Heating Systems are re-emerging as a feasible method for HVAC in homes and LEED businesses. Therefore, the City has modified our building permit application to have a separate box to check when geothermal HVAC systems are installed in homes. The applicant will need to check this box and provide the following information;

  • Description of the type of system being installed; closed-loop, open-loop, water source if applicable, water discharge location, if applicable, and pipe materials to be used.

  • The plot plan (residential permits) or staking plan (commercial and site plan permits) shall reference the locations of the well(s), piping systems and any other pertinent site information.

  • The current code requires a permit with fee for all water wells drilled within the City. The current 2009 and 2010 fee is $20 per well drilled.

This information shall be submitted to the City of Dublin with the rest for the required building permit submission. Engineering and Building will review the submitted information for compliance with Dublin City Code Section 52.03.  Please contact City of Dublin Engineering at 614-410-4657 if you have any further questions or require additional information.
