Indiana, Marshall County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Marshall County HVAC Permit Requirements
Marshall County, Indiana, has specific requirements for HVAC permits, primarily managed by the Marshall County Building Commission. This commission is established by local ordinance and state code to ensure that all construction and modifications within the unincorporated areas of the county meet minimum state standards. The Building Department administers and enforces standards for heating, ventilation, and air conditioning (HVAC), among other building trades, to protect public safety and conserve energy.
For properties in unincorporated areas, the Marshall County Building Commission has direct jurisdiction. They are responsible for issuing building permits and conducting inspections to ensure compliance with state-adopted codes, including the International Mechanical Code with Indiana Amendments.
Contractors performing HVAC work in Marshall County must be registered with the Marshall County Building Department. To register, contractors need to provide a Certificate of Insurance with at least $500,000 in liability insurance, Workers' Compensation Insurance or an Affidavit of Independent Contractor Certification, and a $20,000 License and Permit Bond payable to Marshall County. There is a $50.00 registration fee, and registration must be renewed annually, expiring on December 31st of each year.
While Indiana does not have a statewide HVAC license, many local jurisdictions, including Marshall County, have their own licensing or certification requirements. HVAC work, including installation, modernization, replacement, servicing, or repair of HVAC systems, falls under the purview of the Marshall County Ordinance (2013-20), which mandates that any entity engaged in such work for remuneration must obtain a building permit.
Before applying for an HVAC permit, several items must be completed, submitted, and approved. These include a site plan with lot line dimensions and other structures indicated, an assigned property address, driveway permit approval (if applicable), and septic permit approval (if applicable). Applicants must also list all contractors and subcontractors, who must be registered with Marshall County.
The Marshall County Building Department also serves as the permitting and inspection agency for the towns of Argos, Bourbon, Bremen, Culver, and LaPaz. The City of Plymouth has its own Building Inspection Department.
Residential HVAC maintenance that does not involve structural changes or new fuel-gas piping typically does not require a separate permit under the 2020 Indiana Residential Code. However, commercial maintenance inspections may trigger permit requirements depending on the scope, jurisdiction, and local ordinances.
