Pre-construction meeting with an area commercial inspector
Pre-construction meetings are encouraged and, for some projects, may be mandatory. These meetings are included in the cost of your permit, so there's no additional cost. The meetings can be formal, with a large group made up of the project team, City inspector, and interagency partner staff. Or, they can be one-on-one with the area inspector.
Pre-construction meetings provide you with information specific to your project approval. Schedule a pre-construction meeting by calling Commercial Inspections.
