Light commercial buildings are considered up 20,000 sq ft.
Examples would include a house turned into a business or small office units.
The inspection standards are followed the same as a home inspection, and the amount of time to inspect will depend on size.
I will provide Commercial Inspection in the near future with another member. Commercial Inspections are more involved: to include a collection of paperwork on property of interest that the client provides, along with interviews from current owner or property managers.
