Where is the official DC vacant property list?
The official list is the Department of Buildings vacant buildings dashboard at dob.dc.gov/vacantbuildings. It tracks more than 3,400 buildings and lots the District has designated vacant, blighted, or exempt, and anyone can search it. There is no login, no fee, and no requirement that you own the property to look it up.
The dashboard is the front door, but the District publishes the same information in several places, and they don't always agree with each other on a given day. Knowing which source answers which question saves you a lot of confusion.
| Where | What it shows | Best for |
|---|---|---|
| DOB Vacant Buildings dashboard | Every building DOB has designated vacant, blighted, or exempt, searchable by address | Owners checking one address |
| Open Data DC building datasets | Downloadable address-level data on designated vacant and blighted buildings, by ward | Investors and researchers pulling the whole list |
| Integrated Tax System public extract (vacant property) | OTR tax records for Class 3 and Class 4 properties, including owner and mailing address | Confirming what the tax side has on file |
| MyTax.DC.gov property lookup | The current tax class and bill for a single property | Confirming what you are actually being charged |
The dataset behind the tax side is the Integrated Tax System public extract for vacant property on Open Data DC. It comes from the Office of Tax and Revenue, not DOB, which matters: DOB decides who is designated vacant, and OTR decides what rate actually posts to the bill. A property can be fixed in one system and still wrong in the other.
How do I check if my property is on the list?
Search your address on the DOB dashboard, then confirm the tax class on your OTR bill. If the bill shows Class 3 or Class 4, you are on the list, even if no letter ever reached you. Here is the two-minute version:
- 1. Search the DOB dashboard. Enter the street address, or the square and lot from your tax bill if the address search misses. Note the status it shows: vacant, blighted, exempt, or registered.
- 2. Pull the tax record. Look the property up on MyTax.DC.gov and check the class code. Class 1 is the normal residential rate. Class 3 means taxed as vacant, Class 4 means taxed as blighted.
- 3. Check the building itself. DOB posts a bright green vacant property notice on designated buildings. If one is on your door, a designation letter went out, whether or not you received it.
- 4. Compare the two answers. Dashboard says exempt but the bill says Class 3? Dashboard says vacant but the house has a tenant? Those mismatches are common, and they are where owners lose money quietly.
One more thing worth knowing: mail goes to the address OTR has on file. Out-of-state heirs and LLC owners routinely discover a designation a year late because notices went to the vacant house itself.
What does being on the list cost you?
A vacant designation puts the property in tax Class 3 at $5.00 per $100 of assessed value, and a blighted designation puts it in Class 4 at $10.00, under D.C. Code §47-813. An occupied home pays about $0.85. On a $500,000 row house that is $25,000 a year as vacant, or $50,000 as blighted, instead of roughly $4,250. On top of the tax, a building unoccupied for 90 days or more owes annual Vacant Building Registration fees under D.C. Code §42-3131.05. The full rate math, including how the assessment cycle decides when a fix actually shows up on your bill, is in our Class 3 vs Class 4 guide.
How properties end up on the list
Most buildings land on the list one of three ways. A neighbor reports the property through the dashboard's complaint form, a DOB inspector flags it during a survey or while working a violation nearby, or the owner registers it because the law requires registration once a building sits unoccupied for 90 days. DOB then sends a designation notice and the tax clock starts. The program is enforcement, not record keeping: the District wants vacant buildings occupied, and the 5% and 10% rates exist to make sitting on one expensive.
How do I get my property off the list?
Two paths. Prove the building is occupied, or claim one of the statutory exemptions that shields a genuinely vacant building from the punitive rate. Both run through the Vacant Building Response Form, DOB's document for contesting a designation or claiming an exemption. The categories include active construction with a valid permit, a good-faith for-sale listing, pending probate, and documented hardship, each with its own time limit and evidence requirements.
Deadlines drive everything here. You get 15 days from the designation notice to petition, and if the designation is upheld, 45 days to appeal to the Real Property Tax Appeals Commission. Getting removed from the DOB list is also only half the job, because the Class 3 rate has to actually come off the bill at OTR, and that second step is the one nobody follows up on. If DOB already said no once, read our walkthrough on fixing a denied vacant property exemption before you refile.
Buying a property that's on the list
Plenty of people search the DC vacant property list to find deals, and the boarded-up estate sale or the fire-damaged row house can be a good buy. Just price in what the list status means: the tax class transfers with the property, not the owner. Close on a Class 3 building and you are the one paying 5% until you get it reclassified. Check the dashboard and the tax record before you write the offer, ask whether prior owners already burned exemption time (exemptions cap at 5 years in any 12-year period), and budget the reclassification work into your rehab timeline. The for-sale exemption clock runs from the initial listing date, so a house that sat on the market for months may arrive with nothing left to claim.
If your building is on the list right now
Don't wait for the next assessment cycle to sort itself out; it won't. Send us the address and we'll pull the full record for free: what the DOB dashboard shows, what OTR is actually charging, open violations, registration history, and which exemption fits. If the fix is simple, we'll tell you and you can file it yourself. If it's tangled (probate, open violations, a designation that's flat wrong), we handle the whole path back to Class 1, and our fee is 35% of first-year savings. No savings, no fee.
