A. In the Counties of Arlington, Fairfax, Loudoun, and Prince William, and the Cities of Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park, upon the adoption of an ordinance so providing, all new buildings shall be assessed when substantially completed or fit for use and occupancy, regardless of the date of completion or fitness, and the commissioner of the revenue of such county, city or town shall enter in the books the fair market value of such building.

C. With respect to any assessment made under this section after November 1 of any year, no penalty for nonpayment shall be imposed until the last to occur of (i) December 5 of such year or (ii) 30 days following the date of the official billing.
