To determine the estimated reproduction cost of a subject building using the square-foot method, the appraiser takes the ______ and multiplies it by the cost per square foot of a recently constructed comparable structure.

The estimated reproduction cost of a subject building is determined by calculating the square footage of its living area and then multiplying that figure by the cost per square foot derived from a recently constructed comparable structure. This method relies on assessing the specific square footage that is conducive to housing or occupying space, which is critical for appraisers aiming to establish a reliable cost estimate.

Using the square footage of the subject building's living area provides a clear and standardized metric. It aligns with the idea that construction costs directly correspond to the size of the building being evaluated. This approach offers a straightforward calculation that reflects how much it would typically cost to reproduce a similar space based purely on its dimensions, rather than broader or unrelated factors such as land area, material costs, or overall market value.

The correct choice effectively leverages the principle of correlation between size and cost in real estate appraisal. By focusing specifically on the living area, the appraiser ensures that the measurement corresponds closely with the functional aspects of the building, leading to a more accurate assessment of reproduction costs.
