DC posts Integrated Tax System vacant-property extract on Open Data DC

The District of Columbia this week published a public extract from its Integrated Tax System that lists properties classified as vacant and made the file available on the city’s Open Data DC portal. The release compiles city-held tax records flagged with a vacant status so developers, neighborhood groups, agencies and members of the public can access the same underlying data used by government staff.

The dataset sits on the Open Data DC platform, the city’s public data portal, and is distributed as a technical extract intended for analysis and integration. The extract aggregates ITS records that the District identifies as vacant, allowing users to search, download or query the records for research, enforcement, or planning work.

City officials and data administrators have in recent years pushed to make more administrative records available to residents and stakeholders; publishing an ITS extract focused on vacant property follows that trend toward transparency. Local housing advocates, neighborhood organizations and potential developers will likely use the file to track concentrations of vacant buildings, spot potential sites for rehabilitation, or cross-check enforcement lists maintained by code and tax agencies.

What the dataset provides

The extract compiles records drawn from the District’s Integrated Tax System that have been designated as vacant. It is distributed through the Open Data DC portal where users can access the raw dataset via direct download or by connecting to the portal’s API endpoints. The dataset is technical in nature and is designed for analysts, reporters, researchers and software developers who need machine-readable records rather than a narrative report.

Because the file mirrors administrative entries in the city’s tax system, it can serve as a cross-reference for enforcement units and for community groups tracking absentee ownership, disinvestment, or properties that may be subject to tax remediation or other municipal actions.

Local uses and limits

Neighborhood groups can use the extract to map clusters of vacant properties and prioritize local outreach or advocacy. Real estate professionals and developers may incorporate the data into screening and site-selection workflows. City agencies that enforce property maintenance, tax compliance, or housing codes can use the public extract to complement internal lists and to improve transparency around enforcement efforts.

At the same time, the extract is a mirror of administrative records and does not by itself change property status or trigger enforcement. Users should treat the dataset as a starting point—one source among others such as building permits, code records and on-the-ground inspection data—when assembling a fuller picture of a property’s condition and legal standing.

Making the ITS vacant-property extract public reduces friction for researchers and civic technologists who build tools to visualize and monitor neighborhood conditions, and it creates a consistent reference that community members can cite in conversations with elected officials or agency staff.

Watch for updates to the dataset and for whether District agencies or the Council incorporate the extract into formal monitoring or enforcement workflows. Changes to update cadence, field definitions or integration with other municipal data sets will affect how useful the file is for long-term tracking.
