What must occur with mechanical plans prior to the start of construction in Michigan?

The requirement for mechanical plans to be submitted for review and approval prior to the start of construction in Michigan is a critical aspect of ensuring that all construction activities comply with applicable codes and regulations. This process allows for an evaluation of the plans to confirm that they adhere to safety standards, zoning laws, and building codes specific to the local jurisdiction.

By submitting the plans for review and approval, the relevant authorities can identify any potential issues or discrepancies that could lead to safety hazards or legal complications during the construction process. This step is essential to ensure that all mechanical systems, such as HVAC, plumbing, and electrical systems, are properly designed and will function as intended within the overall structure.

Filing mechanical plans with the local government, while important, does not inherently guarantee that they have been thoroughly evaluated for compliance, which is a key reason why review and approval is emphasized. Similarly, while a licensed contractor’s review can be beneficial, it is not a formal requirement in the same way that governmental approval is. The requirement for plans to be available on-site is also important for oversight during construction but does not address the critical step of proper review prior to starting the work.
