Property Search Tool FAQs
What is the District of Columbia County Property Search Tool?
The Property Search Tool is an online portal that lets anyone query the DC parcel database. Users can enter an address, parcel identification number (PID), or owner name to retrieve a property’s legal description, assessed value, and GIS coordinates. The tool pulls data from the DC GIS parcel database, which is updated after each assessment cycle.
Is the Property Search Tool free to use?
Yes. The portal is publicly funded and does not charge a fee for basic searches. Users may download a PDF summary of a property’s tax bill for a small processing charge (currently $2.50) if they request a printed copy through the mail.
How often is the District of Columbia County property database updated?
Updates occur twice a year:
- Spring Update: Incorporates new construction, demolitions, and boundary adjustments.
- Fall Update: Reflects the latest market values used for tax assessment.
Each update is posted on the OTR website with a timestamp, for example “Fall 2023 Update – Posted 09/15/2023.”
Can I search using only part of an address or owner’s name?
The tool supports partial matches. Typing “1600 Pennsylvania” returns all parcels on Pennsylvania Avenue, while entering “Smith” lists every owner whose surname contains “Smith.” Results are ranked by relevance, and users can refine the list with filters for property type or tax status.
What should I do if I can’t find my property in the search results?
First, verify the spelling of the address or PID. If the property was built after the most recent Spring Update, it may not yet appear in the system. In that case, contact the Assessor’s office for a manual lookup.

Online Tax Estimator FAQs
What is the District of Columbia County Property Tax Estimator Tool?
The Tax Estimator calculates an approximate annual tax bill based on the most recent assessed value, the applicable tax rate, and any exemptions that apply to the property. The calculator lives on the OTR website under “Tax Tools → Property Tax Estimator.” Users input a PID or address, select the tax year, and receive a dollar amount within seconds.
Can I use the Tax Estimator for any property in District of Columbia County?
Yes. The estimator works for residential, commercial, and vacant land parcels. It does not support properties that are exempt from taxation, such as certain nonprofit facilities, which are flagged automatically.
Does the estimator show the exact tax amount due?
The result is an estimate. The final bill may differ due to adjustments, late fees, or additional charges that appear after the assessment is finalized. Users can download a “Tax Estimate Report” PDF that outlines the calculation steps.
Can I compare tax estimates from previous years?
After generating an estimate, a “Compare Years” button appears. Clicking it opens a side‑by‑side table that lists the estimated tax for the selected year and the two preceding years. The table also highlights any change in exemption status.
District of Columbia County Tax Roll FAQs
