Proving a DC house was occupied: the evidence DOB and RPTAC actually weigh

Two reviewers, two moments

Occupancy gets argued in two places. The first is DOB, inside the 15 day window after the designation notice, on the response form that asks you to take a position: the building is occupied, or it is vacant but exempt. The appeal article walks through that form. The second is the Real Property Tax Appeals Commission, RPTAC, on a reclassification appeal after OTR has already billed the Class 3 half under §47-813. RPTAC publishes what it wants to see on a reclassification appeal, and the list opens with utility bills. Both reviewers are asking the same question about the same dates, and the same file answers both. Build it once.

The definition the evidence has to meet

The vacant building definition in §42-3131.05 turns on whether the building is occupied, and the 2025 amendments in §42-3131.05b list the things the Mayor considers when making the call, which include neighbor complaints, the exterior condition and whether utilities are connected. Notice what that means for your file. The inspector worked from the outside. Your evidence has to show the inside, over time, for the exact half year on the bill. A document that proves someone lived there in March does not prove anyone lived there in September.

Evidence ranked by weight

From what we have seen accepted and rejected, in descending order:

• Utility bills showing consumption. Gas, electric and water, month by month, with the usage column, not the balance column. A house with a resident uses water every month and electricity every month. A bill with zero therms and 0.00 CCF proves the account was open and nobody was home, which is the opposite of what you want. Pull the full year so the reviewer can see the pattern, and if usage dropped to zero on a certain date, know that date before the reviewer does.
• A signed lease with dates that cover the inspection date, plus proof the tenant was in fact there: rent receipts or bank deposits matching the lease, the tenant's utility account if it was in their name, and the basic business license for the unit. A lease alone is a promise; the deposits show it was kept.
• Government records tying a person to the address. A driver's license or DC ID, voter registration, a vehicle registration, a school enrollment, a tax return mailed from the address. These are hard to fake and dated.
• Third party records of life at the house. Mail with postmarks, package delivery confirmations, a renters or homeowners policy that was not written as vacant, a cable or internet account with usage, a pest control or lawn service invoice addressed to the resident.
• Court records in a tenant dispute. A landlord tenant case shows the tenant was in possession through at least the judgment date. The eviction case article explains why that makes the house occupied rather than exempt.
• Affidavits. Yours, the tenant's, a neighbor's. They are read, and they help when they put dates on a story the documents already tell. On their own they rarely carry a case, because every owner of a designated house could write one.
• Photographs. Useful for the exterior condition questions, close to useless on occupancy, because furniture proves nothing about whether anyone slept there. If you use them, make sure the file metadata carries the date.

What does not work

An account in good standing, a paid property tax bill, a homestead deduction on the OTR account, a mortgage statement, a mailing address at the house. Each of these shows the owner was paying for the house, and none shows anyone inside it. The homestead deduction is the one that misleads owners most, because it feels like the District has already agreed the house is the owner's home. OTR and DOB do not cross check, and an owner who moved out and kept the deduction has a different problem on top of the vacancy one. The owner away article covers the furnished house with nobody in it.

Building the file month by month

• Draw a line for the half year on the bill and write the first and last day on it. For the current designation, add the inspection date and the notice date from the timeline.
• Request the full year of utility statements from each provider. Current account holders can download them. If the account was in a former tenant's name, ask the tenant; the utilities will not release a prior holder's history to the owner, so a tenant who has moved on and will not answer is a hole in the file you should know about early.
• Place every other document on the line by its date. A reviewer should be able to pick any month on the bill and find at least one document that shows a person in the house that month.
• Write a one page cover that states the position in the first sentence, the dates in the second, and lists the attachments. No story. The denial article shows what a file that leads with narrative gets back.
• Keep a copy. The same file supports the DOB response, the RPTAC appeal, and the refund claim after the class is corrected.

When the records are gone

Owners who come to us a year or two late often have nothing: the tenant vanished, the utilities were in the tenant's name, the lease was verbal. The file is thinner but not empty. DC Water bills the owner regardless of who lived there, so the water history is usually recoverable even when gas and electric are not, and water consumption alone shows someone was running taps and flushing toilets. Court records are public. The management company or the agent who placed the tenant keeps an application and a move in inspection. Neighbors remember a car in the same spot. A half year that cannot be documented at all is a half year to pay, and the effort moves to the halves that can be.

If you want a read on your evidence before you file, send us the address and a list of what you have. We review the DOB record and the OTR account at no charge and tell you which halves the file supports. Correction work is a flat $1,500 per tax period corrected, paid up front, and refunded in full for any period OTR does not correct.
