How to read a Westchester assessment roll

An assessment roll is a municipal spreadsheet with legal consequences. It lists parcels, owners as the municipality knows them, assessed values, and class codes. Dale Ledger turns those public files (and PROS parcel pages where PDFs are impractical) into a searchable almanac — but you should still know how to read the underlying object.

What a residential roll row usually contains

Parcel ID / SBL — section-block-lot style identifiers. Scarsdale often looks like 13.01.15; Rye PROS IDs often use hyphens like 146-15-3-49.
Situs address — where the property is, not necessarily a mailing address.
Owner / co-owner — as published. LLCs, trusts, and “et al” spellings are common.
Land / total assessed — land component vs total assessed.
Full market value — when the municipality publishes it.
Property class — New York ORPS-style codes (e.g., 210 one-family).
Exemptions — STAR and others as codes.

Tentative vs final

Many New York assessing units publish a tentative roll (open for informal review / grievance) and later a final roll. Dale Ledger labels years by the roll files we ingested. If you are grieving, the calendar and forms on the municipality’s site control — not our UI.

What we filter out

Dale Ledger’s residential almanac focuses on classes that behave like homes people search for: single-family, multi-family, condo, and vacant residential land. Pure commercial rows are generally omitted so the search surface stays useful for household questions.

Street hubs vs parcel pages

Street hubs summarize a whole street (counts, medians, links). Interactive search in each town edition is the fastest way to ask “who owns X” or “tax over 80k.” Parcel HTML pages exist as citeable URLs; for AdSense-quality browsing we emphasize guides and town apps as the primary reading experience.

Verify before you argue with anyone

Match parcel ID and address on the official roll or PROS.
Confirm the roll year (tentative vs final).
Print or save the official page if you are preparing a grievance.
