An interim assessment is derived from a straightforward mathematical calculation. Simply put, the interim assessment represents the value difference (increase) attributable to any assessable improvement to the land. It is important to note that an interim assessment is the difference between the prior and the revised total assessments. These assessable improvements include, but are not limited to; new construction of a primary structure (dwelling or other building type), the addition to any such structure and the construction of secondary improvements such as swimming pools, garages, barns, sheds, etc.
When the Assessment Office is notified of an improvement, one or more field visits are made by a Certified Pennsylvania Evaluator to collect property data.
