Commercial Property Inspections
The frequency of inspections on property owners containing businesses and commercial properties are based on hazard classification, or particular license requirements. Some locations require annual inspections, however all properties are inspected every 3 years at a minimum. Business or commercial properties are anything except 1, 2, or 3 family homes, which have different requirements.
Property owners can contact the department to schedule an inspection, or the department will periodically request an inspection at any given property. There is no fee for the on site inspection, as it is more important to assist property owners in achieving the minimum level of fire safety required by the codes.
