You, as the buyer (or your Real Estate agent) must obtain permission for me to enter the premises in order to inspect the property. It's helpful to notify the Sellers that all utilities must be on and all gas pilots lit prior to the inspection. I will be looking over all areas of the home and its mechanical systems. In order for me to complete the work properly, I must have access to all areas, including the attic, basement, garage, and all mechanical equipment. If I cannot gain access to certain components due to stored materials or some other reason, the inspection cannot be completed. This will be reported as "not inspected" and may create surprises for you when you do finally gain access to these areas.
