Guests are not residents
The vacant building definitions in D.C. Code §42-3131.05 turn on occupancy, and occupancy means someone living in the building. A guest who checks in Friday and leaves Sunday is using the building. They are not living in it. Their mail does not come there, their car is not registered there, and on Tuesday the house is dark again. Over a full year a busy listing can host a hundred people and still have no resident. From the inspector's side of the fence, the signs in the inspection article are all present in the off season: no trash out on collection day, no lights on a weeknight, a lockbox on the railing, a yard nobody tends.
The consequence is the same as for any other empty house. A designation, a 15 day response window, and a Class 3 bill at $5.00 per $100 of assessed value under §47-813. On a $500,000 house that is $12,500 for a half year instead of about $2,125. A listing that nets $30,000 a year in a good year cannot absorb two of those halves.
What the District's short term rental law already requires
Since the Short-Term Rental Regulation Act of 2018 took effect, a DC host needs a short term rental license from DLCP, and the licensed unit must be the host's primary residence. A host who rents the whole home while away needs the vacation rental endorsement, and vacation rental nights are capped at 90 per calendar year. The platforms are required to pull listings that carry no license number.
Read those rules next to the vacant building law and the picture sorts itself out. A licensed short term rental is by definition somebody's primary residence. The host lives there. The house is occupied whether or not a guest is in the spare room, and a vacation rental host who is away 90 nights a year still lives there the other 275. A licensed unit run by the rules is not a vacant building and should never be designated. If it is, the fix is the response form with the host's own proof of residence: a DC driver's license at the address, a homestead deduction on the OTR account, utility bills in the host's name.
The exposed unit: an investor listing with no resident
The exposure is the unit that was never anyone's primary residence. An owner who moved out and kept the house as a full time listing, an LLC that bought a condo to run on the platforms, a rowhouse split into three units that are all listed year round. These arrangements are common and most of them are outside the short term rental license, which means the owner has two problems, and the vacant building designation is the more expensive one.
When that owner gets a DOB notice, the instinct is to reply that the house is rented constantly and attach the booking calendar. That reply does not work, and it can make things worse. It tells DOB the building has no resident, which is the definition of vacant, and it tells DLCP the listing is operating without the license it needs. We have seen owners talk themselves into a Class 3 bill and a licensing problem in one letter.
The exemptions do not fit a short term rental
The categories on the exemption formare construction, a pending permit, for sale, for sale or rent, probate, pending development approval, and hardship. None of them is "listed on Airbnb." The closest is actively for rent, which runs half a tax year on a single family house and up to 2 tax years on a multifamily building, and requires a basic business license for the rental and a good faith listing at a market rent. A short term rental license is not a basic business license, and a nightly listing is not a lease listing. Our rental turnover article covers what a qualifying listing looks like. An owner who wants the for rent exemption has to actually put the unit on the long term market, with the license to match.
The 5 in 12 cap applies to whatever exemption time the property has already used. A house that spent time in the construction exemption during its renovation has less runway left, and the cap follows the property, not the owner, as the buyer's article explains.
Three ways to make the building occupied
- Move in and host from home. Rent the spare room or the basement unit while you live upstairs. This is what the DC license was built for, the building is occupied by any reading, and the listing becomes legal at the same time.
- Put a resident in the unit and keep hosting elsewhere. A tenant on a lease with a basic business license, or a family member who moves in with mail delivered there. The unit is occupied. The short term income goes away, but so does the $12,500 half.
- Convert to a medium term rental. Monthly furnished rentals to a traveling nurse, a fellow, or a relocating family put a person in the building for months at a time. Whether a 3 month furnished tenant counts as a resident to DOB is a facts question, and a lease, a mail forward and a car on the block answer it far better than a booking receipt.
If the notice already came
Calendar the 15 days from the letter date and read the appeal steps. If the house was your primary residence and you hosted from home, respond with residence evidence and the designation should not survive the determination. If the house had no resident, the response form is not the place to argue about bookings. Decide which of the three arrangements above you will use, start it before the determination, and register the building in the meantime so the registration fine does not land on top of the tax.
Pay the Class 3 half on time while you work. An unpaid half is what reaches the tax sale, and a lien on the house is a worse problem than a bad tax class. Once a resident is in place and the designation is corrected, the overpaid half comes back through the refund process, with a 3 year window from the date of each payment.
If you would rather hand it off, send us the address and tell us honestly how the unit has been used. We read the DOB record and the OTR account at no charge and tell you whether the designation can be corrected and what it will take. 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.
