What is DC Class 3 vacant property tax?

Class 3 is the District of Columbia’s tax classification for residential property designated vacant by the Department of Buildings (DOB). The rate is $5.00 per $100 of assessed value under D.C. Code § 47-813(d-1), roughly 6× the Class 1 residential rate of $0.85.

What is DC Class 4 blighted property tax?

Class 4 is the District of Columbia’s tax classification for property designated blighted by DOB. The rate is $10.00 per $100 of assessed value under D.C. Code § 47-813(d-2), roughly 12× the Class 1 residential rate.

What is the DC Department of Buildings (DOB)?

DOB is the agency that took over building inspection, vacant-building designation, and code enforcement when DCRA was split in 2022. DOB issues vacant and blighted designations, conducts inspections, manages the Vacant Building Registration program, and runs status-review hearings.

How do I get my building removed from the DC vacant property list?

Two paths: qualify for a statutory exemption (active building permit, active sale or rent listing, pending probate, fire damage, etc.) or return the building to occupied or compliant status and request DOB reclassification. Open DOB violations generally block reclassification until cured.

What DOB exemptions are available from Class 3 / Class 4?

Active construction (up to 3 tax years with a valid permit), active for-sale or for-rent listing (half a tax year for single-family, up to 2 for multifamily/commercial), probate or title litigation (up to 3), pending zoning/development approval (up to 2), and documented economic or personal hardship including fire (up to 2). The total is capped at 5 exemption years in any 12-year period under D.C. Code §42-3131.06a. Each requires specific DOB-accepted documentation submitted within the filing window.

How long does reclassification take?

Most DOB exemption decisions come back within 60–120 days of a complete filing. Effective dates depend on filing timing relative to the assessment year, which is why getting the application correct the first time matters.

Can I appeal a DOB vacant or blighted designation?

Yes. DC owners have the right to appeal and to request a DOB status review hearing. The window is short and the evidentiary requirements are specific. We prepare the file, draft the brief, and represent owners through the hearing.

How much does this service cost?

The initial review is free, and our fee is 35% of your first-year tax savings. No savings, no fee.

What happens if you can’t get my property reclassified?

The $1,500 retainer is refunded in full. You owe nothing beyond that. The refund terms are written into every engagement letter, not buried in fine print.

Inherited a Vacant House in DC? Taxes, Deadlines, Options

Why an empty inherited house is a tax problem in DC

The District taxes occupied homes (Class 1) at $0.85 per $100 of assessed value. Once the Department of Buildings (DOB) designates a building vacant, the Office of Tax and Revenue moves it to Class 3 at $5.00 per $100. On a $500,000 rowhouse, that's the difference between about $4,250 a year and $25,000 a year. If the house deteriorates enough for DOB to call it blighted, the rate doubles again to $10.00. Our Class 3 vs Class 4 guide breaks down the full rate structure.

Inherited houses are prime targets for a vacant designation. Mail piles up, the lawn goes shaggy, utilities get shut off to save money, and a neighbor calls 311. A DOB inspector doesn't know the owner died. They see an empty building, and the designation process starts.

The probate exemption can protect you for up to 3 years

DC law recognizes that estates take time. A property tied up in probate or in litigation over title qualifies for an exemption from the vacant classification for up to 3 tax years. Filed correctly and on time, it keeps the house at the normal Class 1 rate while the estate gets sorted out.

The catch: nothing about this is automatic. DOB doesn't check probate court records before designating a building. The personal representative (or an heir, if no one has been appointed yet) has to respond to DOB with documentation: the death certificate, the probate case number from DC Superior Court, and proof of the filer's connection to the estate. Miss the filing and the exemption you were legally entitled to simply never happens.

You have 15 days to respond to a designation notice

When DOB designates a building vacant, it mails a notice to the owner of record. For an inherited house, the owner of record is often the person who died, so the notice goes to the empty house or an old address. The response window is 15 days. Estates blow through it without anyone ever seeing the letter.

Missing the window doesn't end the fight, but it makes everything harder and slower. You move from a simple response into requesting reconsideration and status review hearings while the Class 3 rate is already accruing on the bill. If you've inherited a DC property and haven't checked its DOB status, do it now, before a notice you'll never receive starts a clock you didn't know existed. The Vacant Building Response Form guide walks through the actual paperwork.

What to do in the first 30 days

Pull the property's current status. Check whether DOB already carries the address as vacant and whether OTR has it on Class 3. Many heirs discover the designation happened months before the death was even settled.
Keep utilities on. Active electric and water service is one of the strongest signals DOB uses to judge occupancy. Shutting them off to save $80 a month can cost $20,000 in reclassified taxes.
Open probate promptly. The exemption needs a case number. An estate that drifts for a year without a filing has no paperwork to point to.
Maintain the exterior. Boarded windows, broken glass, and an open rear door push a building from vacant toward blighted, and blighted properties lose access to most exemptions.
Register if required. A designated vacant building must be registered with DOB under the Vacant Building Registration program, with fees attached. Skipping registration adds fines on top of the tax problem.

Planning to sell? There's an exemption for that too

Many heirs just want to sell. An active listing with a licensed agent qualifies a single-family house for its own exemption covering half a tax year. It sounds short, but paired with the probate exemption it usually covers a normal estate sale timeline. The sequencing matters: exemption years are capped at 5 in any 12 year period, so burning them in the wrong order costs real money if the sale drags.

The math on getting this right

Say the estate takes 18 months to close and sell a $500,000 house. Handled correctly, the property stays at Class 1 the whole time: roughly $6,400 in tax. Handled late, with a missed notice and a year on Class 3 before anyone responds: $25,000 or more, plus registration fees and the legal cost of unwinding it. The estate's other heirs will want to know why.

We handle this for DC estates start to finish: pulling the DOB record, filing the exemption with the right documentation, and correcting the tax class at OTR. The review is free, and our fee is 35% of first year savings only if we win. Send the address through the form below and we'll tell you exactly where the property stands.
