How should finished areas be measured if they are attached to a house?

When measuring finished areas attached to a house, the method of using the centerlines between adjoining properties is appropriate because it establishes a clear boundary that distinguishes the property being measured from neighboring properties. This approach provides a consistent and standardized way to define the limits of the finished area, ensuring that measurements reflect an accurate representation of the usable space in relation to the property lines.

By measuring from the centerlines, it allows for a fair and equitable assessment, especially in situations where properties are adjacent to one another. This also aligns with various land use and zoning regulations that may be in place, which often reference property lines as a basis for determining the extent of usable space. The other measurement methods listed would not provide the same level of accuracy and could lead to discrepancies in how finished areas are defined and utilized.
