New construction, structural additions, and renovations to a home result in an increased value and an increased property tax assessment. The assessor is responsible for the determination of assessed value for new construction/renovations completed in the tax year. The process includes the review of all permits, certificates of approval and occupancy, inspection of properties, and valuation of the added assessment. An added assessment is prorated based upon the number of months the work has been completed. For example, if construction is completed in February, the added assessment would be prorated for ten months of the year. Added assessment bills are typically sent in early October and due by November 1st.
