a. Regarding inspections of real property for purposes of a municipal-wide reassessment pursuant to R.S. 54:4-23, in the case of a municipality located in a county wherein the county board of taxation is participating in the demonstration program established in section 4 of the "Real Property Assessment Demonstration Program," P.L. 2013, c. 15(C.54:1-104), in the case of a county operating under the "Property Tax Assessment Reform Act," P.L. 2009, c. 118(C.54:1-86 et seq.), and in the case of a county that has adopted, by resolution, the provisions of section 1 of P.L. 2018, c. 94(C.54:1-105), the assessor shall make three good-faith attempts to physically inspect the interior of each of the properties in the municipality not later than December 31 of the year immediately preceding the year of the implementation of the proposed district-wide reassessment. Such inspections may be performed in an ongoing assessment cycle. If, after the third attempt to inspect the interior of the premises, access to the interior of the premises has not been granted by the property owner, the assessor shall assess the property using other observations and sources, including information on the property record card maintained by the assessor. As used in this section, "good-faith attempt to physically inspect" shall mean that the assessor, an employee of the municipality acting on behalf of the assessor, or a representative of a revaluation company or other company hired by the municipality to provide internal inspection services, shall physically arrive at the parcel of real property and request entry to the interior of the property. If that person is unable to gain entry to the property to perform an interior inspection, the person shall complete the exterior inspection and shall leave a notice affixed to the front door of the property stating that an attempt was made to inspect the interior of the property, with the appropriate contact information prominently displayed on the notice.
