The size of the home and square footage is one of the first questions asked by a home inspector, and it's one of the biggest determining factors in determining the cost of a home inspection. Inspectors use the information to establish not only the length of time the inspection will take, but also to help calculate the liability involved. After all, the more items there are to inspect, the greater the number of details required in the report.
Most home inspectors will include all areas to be inspected with the square footage estimates. This is not restricted to the number of square feet in the main living area, but also typically includes the garage, the basement and any outbuildings the buyer would like to have inspected. When you call a home inspector for an estimate, be sure to get a price quote based on all areas you would like included in your report.
