Michigan, Ogemaw County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
Ogemaw County HVAC Permit Requirements
Ogemaw County's Building Department is responsible for issuing all construction-related permits and conducting inspections throughout the county. This includes permits for mechanical work, such as HVAC installations and repairs. It is important to note that separate applications are required for plumbing, mechanical, electrical, and soil erosion permits.
Mechanical work generally requires a permit. Permits are typically needed for new equipment installations, changes in equipment capacity, alterations to gas or electrical connections, and any work that penetrates the building envelope. This includes installing new furnaces, air conditioning units, heat pumps, replacing older systems, extending or relocating ductwork, adding new zones, or connecting gas lines to heating appliances.
While most HVAC projects require a permit, there are some exceptions. For instance, portable gas heating appliances with an input rating of less than 30,000 Btu per hour, portable ventilation equipment, and portable cooling units may not require a permit. Additionally, minor repairs that do not alter the approval or safety of existing equipment may be exempt. However, it is always best to confirm with the Ogemaw County Building Department regarding specific project exemptions.
For properties in unincorporated areas of Ogemaw County, the county's Building Department has jurisdiction. The permit requirements and processes are generally consistent across the county, regardless of whether a property is within a city or an unincorporated township. It is advisable to contact the Ogemaw County Building Department directly for the most accurate and up-to-date information regarding permit requirements for your specific location and project.
Plans are generally not required for one and two-family dwellings if the total heating/cooling system input rating is 375,000 Btu's or less. Plans are also not required for minor alterations and repair work, or for certain business, mercantile, and storage buildings with HVAC equipment only, not exceeding 3,500 square feet. Work completed by a governmental subdivision or state agency costing less than $15,000 may also be exempt from plan requirements.
Permits must be secured prior to the start of any project. If work is not commenced within 180 days of permit issuance, or is suspended for 180 days, the permit becomes invalid. Expired permits cannot be reopened; a new permit would need to be secured.
