How the ratio works: New Jersey towns often assess below full market value. The average ratio (Director’s / Chapter 123) estimates what percent of true market value the town’s assessments represent. Implied equalized value ≈ assessed net ÷ (ratio ÷ 100). Example: assessed $187,600 at 55.89% ≈ $335,700 equalized. Tax bills still use assessed value × the general tax rate — not the equalized figure.

Change since the 2024 sale of $467,500: implied equalized value $494,400 is $26,900 above that sale. This is not an appraisal. This is a reassessment year, so the ratio is treated as about 100% and the gap is today’s assessment minus the sale price.

This class 2 — residential (four families or less) — net assessment sits above the town class-2 average of $473,066.

This town revalued/reassessed for tax year 2026. New assessments are set near true market value, so we treat the ratio as ~100% for this year. Published Chapter 123 average ratio for appeals/statistics is still 89.15% (often still reflecting the prior assessment base).

Building permits for 215 ANN ST.

Flood zone for 215 ANN ST.

The flood map could not be checked for 215 ANN ST., because the address did not place a point on the map. Assessment and tax figures on this page are from our own records.

The state’s 10-foot ground scan puts the lowest cell on this lot at 52.9 feet and the highest at 54.4 feet (NAVD88).

These figures are estimates. The zone and any flood elevation come from FEMA’s flood map at a point for this address, and that point can fall in the street. The high and low come from the state’s 10-foot ground scan of the lot outline. A cell can catch a ditch, the street, or the edge of the lot. They are not a survey and not an insurance rating. A licensed surveyor measures the ground and the building. The town floodplain administrator, or a licensed engineer, confirms what the zone means for this lot. No zone at this point, or zone X, does not mean the lot will not flood.

Water and sewer for 215 ANN ST.

The water and sewer maps could not be checked for 215 ANN ST., because the address did not place a point on the map.
