Will I need mechanical, electrical or plumbing permits?

Permits shall be purchased for all work associated with the new use/occupancy and commercial buildings require licensed electricians and plumbers to complete the work. Below is a list of additional permits commonly required for cannabis facilities.

  • Electrical Permit: Dedicated outlets are needed for all mounted light fixtures, fans etc. (extension cords are not allowed for permanent fixtures.) Additionally, increased lighting/mechanical loads may require increasing the size of the electrical panel/breaker/service.
  • Mechanical Permit: New exhaust fans shall be installed and exhausted to an approved location per the currently adopted IMC. To prevent noxious odors, we recommend using a carbon filter or other odor mitigation on your exhaust air.
  • Plumbing Permit: Where cultivation occurs, the building shall be equipped with an approved backflow prevention device on the service line. If you are using a hose or faucet to water the plants, it shall also be equipped with an approved backflow prevention device.
