FY2026–27 final assessment roll · Extract 2026-05-15
+581.4% change in DOF market value from the prior year.
DOF values are used for property taxation. Condo and co-op tax valuations can differ substantially from sale prices. This is a tax-purpose estimate; comparable sales remain a separate valuation source. Roll exemptions can include STAR under DOF’s published layout.
These values cover the whole tax lot and do not value individual co-op shares.
Official DOF final assessment roll (ZIP) ↗FY2026–27 · DOF statement 2026-08-15 · 817 CLASSON AVE.
DOF tax-purpose market value on this statement: $3,441,000.00.
This covers the whole tax lot. Co-op building taxes cannot be added to an apartment’s maintenance or divided among its units.
Read official DOF tax bill ↗How we calculate your annual taxes: Billable assessed value: $1,336,170.00 times the current tax rate: x 12.4390% Annual property tax: $166,206.20
HOA, common charges and maintenance require documented building or unit evidence. Sales and DOB records do not establish these amounts. A zero property-tax bill does not establish zero PILOT or other ownership charges. Bills may change with tax rates or benefits; monthly figures are annual equivalents.

Final exemption values reduce assessed value; they are not cash savings or annual taxes. No expiration date inferred from a start year or duration.
Published benefit amounts and dates do not guarantee eligibility after a purchase. An end date alone does not establish the future tax bill; assessment, tax rate and other benefits may change.
