Data freshness

Every dataset, dated and sourced

Verdwise keeps its data maximally current from official public sources: City of Boston open data refreshes daily through an automated pipeline, several panels query the City's own services live at request time, and static reference layers are labeled with their vintage. Two dates are shown for each dataset because they answer different questions: 'last synced' is when our copy was refreshed; 'latest event' is the newest real-world record inside it.

Last syncedwhen Verdwise's copy of the dataset was last refreshed. Latest eventthe newest real-world record inside the dataset.

ZBA decision corpusSnapshot

Every Boston Zoning Board of Appeal case we could recover from the City's published decision documents and appeal tracker, feature-extracted from the decision text.

  • Caveat One row per appeal: the City's raw export contains dash/no-dash twin rows for the same case number; twins are merged at load (audit 2026-07-24), so this count is lower — and more honest — than the raw export's.
  • Caveat Withdrawn and void appeals are excluded from the decided count and the approval rate.

City ZBA appeal trackerSnapshot

The City's milestone-by-milestone record for every ZBA appeal, mirrored from data.boston.gov. Powers application status, upcoming hearings, and statutory-clock features.

  • Caveat Hearings are scheduled through 2026-10-22.
  • Caveat The tracker is the City's own live record of appeal milestones (submitted, received, hearing, decision, closed); we mirror it daily and keep one row per appeal number.

Decision datesSnapshot

A decision date for each ZBA case, recovered from the decision documents and the City tracker so every outcome can be placed in time.

Archived decision documentsSnapshot

Locally archived City decision PDFs, served per case from decision search and case packets.

  • Caveat The City publishes decisions as one batch PDF per filing day, so each file contains every decision filed that day.
  • Caveat Archived filing days span 2021 to 2026; earlier hearing days are not archived locally.
  • Caveat 48 of 296 hearing-day files referenced by the corpus could not be recovered from the City's links and are not in the archive.

Pre-2021 decision listingsSnapshot

For 2017-2020 the City published no decision documents — it published plain lists instead: case number, address, ward and outcome, grouped by hearing day. Parsed here as a second City source for those years, and as the only record of which older appeals were heard together.

  • Caveat Covers 2017, 2018, 2019, 2020 only. 2021 onward is document-backed and lives in the decision corpus instead.
  • Caveat Outcome is trustworthy on the 2393 of 3486 records whose hearing day printed both an APPROVED and a DENIED section. On days that printed only an APPROVED heading the City files the whole day under it, so denied appeals read as approved — those rows are flagged and never override the appeal tracker.
  • Caveat These listings carry no reasoning and no conditions; those exist only in the signed documents, which are not published for these years.

FY2026 property assessment rollSnapshot

The City's full FY2026 assessing roll — addresses, owners, lot sizes, values. Powers address search, abutter owner lookups, and record cards.

  • Caveat FY2026 vintage — the current roll the City publishes; assessed values change on the City's own annual cycle, not ours.

311, violations & RentSmart recordsSnapshot

Per-parcel city problem history: ISD code-enforcement violations, property-relevant 311 complaints, and the City's RentSmart roll-up.

  • Caveat Counts are city-recorded facts, not a verdict — a building can have issues the city never recorded.
  • Caveat 311 complaints are limited to property-relevant reasons and to requests opened since 2023-09-08.

Business licensesSnapshot

City license records per parcel: Section 12 alcohol, Licensing Board (all types), cannabis, active food establishment, one-day alcohol, and entertainment licenses.

  • Caveat One normalized table across seven City licensing datasets; the Licensing Board dataset overlaps the Section 12 alcohol dataset, so duplicate license numbers are kept once.
  • Caveat 79.5% of records are linked to a parcel (via the City's SAM address system, address matching, or the license's own coordinates); the rest keep their address and stay searchable without a parcel link.
  • Caveat Includes one-day alcohol and one-time entertainment licenses — records of past events at a location, most of them expired.

Building permits (issued)Snapshot

Every building permit the City has issued, with work type, declared valuation, status and address — joined to a parcel where the City's own record allows it.

  • Caveat Issued permits only. Applications still in review, denied, or abandoned are not in this feed — those are in the permit review & inspection pipeline dataset.
  • Caveat 99.7% carry a parcel id from the City's own export; the rest stay searchable by address.

Permit review & inspection pipelineSnapshot

Where each building permit sits inside Inspectional Services — its current review or inspection stage, how long it has been there, the plan-review rows, and the city staff named on them.

  • Caveat The City's published permit feed lists issued permits only. This dataset adds the review and inspection stages behind them, including applications that were denied, abandoned, or never issued — 26,768 permits here have no row in the published feed.
  • Caveat Each permit's CURRENT stage, not a stage history: the City's system publishes where a permit sits now and the date it got there, not the path it took.
  • Caveat Enumerated by walking the City's permit-number sequence and querying each candidate; permits outside the walked range, or dropped from the City's system, are not represented.
  • Caveat 98.8% of permits are linked to a parcel (through the published permit feed, then the City's SAM address system); the rest keep their address and stay searchable without a parcel link.
  • Caveat City contact names are the staff named on a permit's current stage — a record of who handled what, not an assignment roster.

Status transitions (change history)Snapshot

What changed and when Verdwise saw it change — permit statuses, ISD review stages, and Article 80 project stages diffed daily. The only record of movement; every other dataset is a snapshot.

  • Caveat Observed day-over-day, never backfilled: the City publishes no history, so coverage begins the day watching started and a missed day is permanently missing.
  • Caveat Three families watched: building-permit status, ISD review stage, and Article 80 project stage.

City address flags & food establishmentsSnapshot

The City's own per-address designations — problem property, income restriction, short-term-rental registration and eligibility, open violation counts — plus active food licenses with inspection history.

  • Caveat Flags are the City's designations as published — currently 2 problem-property addresses citywide; absence from the table is absence from the City's list, not a clean bill.

City services by address (trash day, councilor, neighborhood facts)Snapshot

The everyday City facts for an address: trash collection day, city council district and councilor, Neighborhood Services liaison, library branch, community center, pool, fire company, police station, ward and precinct, and historic district.

  • Caveat 3,955 addresses (1.0%) have no collection day in the City's table — those are reported as 'not listed', never filled in from a neighboring address.
  • Caveat The trash resource publishes a collection day only. It does not state the recycling day separately, so recycling is never asserted — for the 135,530 twice-weekly addresses the data does not say which of the two days it falls on.
  • Caveat Street sweeping is NOT included. The City's schedule is by street segment and side of street; its published ranges are linear feet along the centerline, not house numbers, and the address data does not record which side of a street an address is on — so no honest address-level sweeping answer exists from this source.
  • Caveat Snow emergency parking lots are NOT included: the source joins every address in Boston to one South Boston garage restricted to South Boston residents. Polling/early-voting is NOT included: the only schedule in the source is undated and from a past election. Ward and precinct are served instead.
  • Caveat Park, snow emergency route and splash pad are the City's nearest-facility computations and are labeled 'nearest' — they are not necessarily on the address's own street.

Neighborhood profiles (BPDA estimates)Snapshot

Population, derived median income, poverty, tenure, education and 2020-24 housing production per neighborhood, from the City's own BPDA research tables.

  • Caveat Estimates, not counts: ACS-derived modeling by BPDA; median income is interpolated from the published distribution and is always labeled 'derived'.

Recorded deeds & sales (Suffolk Registry)Snapshot

The Registry's own index of every land document recorded in Suffolk County, swept daily: document type, recording date, book/page and street address for each — the card catalogue, days-current, where the free assessing feeds stop at 2022. Parties and consideration are not in the index; they come from the per-document detail page, which is pulled for a subset (counted below). The recorded document itself — and the legal description inside it — is a separate scanned image at the Registry, fetched on request.

  • Caveat Coverage window 2016-04-04 to 2026-08-28 — the sweep watches forward and backfills; earlier history is not yet captured.
  • Caveat Nominal ($1) consideration marks family/trust conveyances and is never presented as a price.
  • Caveat The index carries no grantor/grantee or price — those exist only for the detailed subset. Treat the full count as 'a document was recorded here', not as a priced sale.

Parcel boundaries & abuttersLive query

Lot-boundary polygons and 300-ft abutter lists, computed from the City's own Parcels (2025) map service at request time; owner/mailing details join the FY2026 assessing roll.

  • Caveat No local snapshot to count — geometry comes from the City's service at the moment you ask.

Zoning map layerSnapshot

Boston parcel geometry joined to BPDA zoning subdistricts — the base layer for district lookups and compliance checks.

  • Caveat Static extract — zoning map amendments adopted after the sync date are not reflected; verify current districting against BPDA's own zoning viewer before relying on it.

BPDA as-of-right envelopeSnapshot

The BPDA's own city-computed base-zoning requirement (FAR, height, units, lot size) versus existing conditions, per parcel.

  • Caveat Existing building height is the City's circa 2010-2011 LiDAR model — a frozen vintage that can describe a prior structure on parcels redeveloped after ~2010 (responses annotate this per parcel).
  • Caveat Reflects the base-zoning requirement before any variance or other relief already granted on a parcel.

Zoning Reform Impact Tracker (ZRIT)Snapshot

The City's own parcel-level record of what recent zoning reforms allow by right — the denial-driver and reform-watch backbone.

  • Caveat Denial-driver trend figures are computed by live SQL against data.boston.gov at request time, so they can be newer than this snapshot.

Neighbor testimony excerptsSnapshot

Public-comment excerpts from recorded ZBA hearings, matched to cases near a parcel.

  • Caveat Excerpts are taken word-for-word from transcripts of the City's recorded hearings (public-testimony portion) with a link to the recording; cases whose transcript segment could not be located unambiguously are omitted.
  • Caveat 853 hearings examined; only the 167 with unambiguous, verified excerpts are published.

Approval-condition excerptsSnapshot

Exact condition/proviso language quoted from City decision documents for approvals that came with strings attached.

  • Caveat Every published excerpt is verified as an exact substring of the decision document's OCR text, and only ships when condition/proviso language provably precedes it in the source — unverifiable extractions are dropped, which is why this count is deliberately small.

FAA airspace geometrySnapshot

Deed referencesLive query

Vesting-deed book/page references per parcel, from MassGIS's statewide parcel attributes — queried live, with a hand-off to the Suffolk Registry for the recorded document itself.

  • Caveat Book/page is as published by MassGIS; the recorded deed image lives at the Suffolk Registry of Deeds and should be verified there.
