The vacant building statute has no pause for a casualty, and a boarded burned house is the most visible empty building on the block. Where fire sits in §42-3131.06a (a hardship ground tied to a Fire and EMS investigation, not a separate exemption), how the hardship years and the construction exemption fit together, why the house still has to be registered and boarded to the DOB standard, and a checklist for the first month.
The construction exemption is written around a valid active building permit, not around effort, so paint, floors and a new kitchen leave an empty house on Class 3. How a permit application alone starts a half year clock, what the inspector reads in the public permit record before the visit, how after the fact permits work, and the order that turns a fix up into a claim DOB can grant.
The tax exemption under §47-1002 rests on use, so a sanctuary where worship stopped can lose it, and the sworn report under §47-1007 due before April 2 is where that happens. The vacant building statute applies to every owner and its current exemption list has no nonprofit category. Why Class 3 costs nothing while the exemption holds, why the listing still matters, and what a board should do this month.
A finished house with no resident is a vacant building the day the last worker leaves. How the construction exemption carries the build, why the certificate of occupancy is the moment it stops, what the for sale listing exemption covers after that, the gap between the two that gets billed, and the order a builder or a buyer of an unfinished house should follow.
An empty contributing building answers to two tracks at once: the vacant building statute that drives Class 3, and §6-1109.03, which lets the Mayor get a Superior Court order to repair a landmark or contributing building and charge the cost back as a lien. Why historic review slows the usual exits, and the order an owner should follow.
Class 3 and Class 4 cover improved real property on the vacant list, and the statute defines a vacant building as real property improved by a building, so an empty lot is classed another way. What the DOB form means by vacant lot, what a lawful teardown does to a designation already on the record, and why razing is usually the wrong answer to a Class 3 bill.
The statute counts only lawful occupancy, so a squatter leaves the building vacant for tax purposes and adds the open to entry factor on top. What the unlawful entry statute and its boarded building presumption do for an owner, why a possession case is not the litigation exemption, how the months are billed, and the order that secures the house and answers the designation.
The definition works at the building level, and one lawful resident makes the building occupied with no fraction in between. The rowhouse with a basement tenant, the mixed use building with a dark storefront, the open shop under empty apartments and the commercial unit rule that changes it, and what to send DOB when a partly occupied building gets a notice anyway.
Section 42-3131.12 lists fifteen things a vacant building must be at all times and requires a maintenance plan with the registration that names the person watching the house. The list grouped as an inspector walks it, what the plan must contain, why the standard is the whole difference between Class 3 and Class 4, and a quarterly walk through.
The homestead deduction says an owner lives in the house and a vacant designation says nobody does, so OTR drops the deduction, the senior relief that rides on it and the cap on assessment increases. Why the deduction can become evidence against you, how a temporary absence is treated, and the order to get it back once the class is corrected.
A building open to entry or overgrown can be secured, cleaned or cut by a District crew, and the cost comes back as a special assessment lien. How that power runs on a separate track from the designation, why the Court of Appeals says RPTAC cannot hear a dispute over the lien, and what to do in the window before the crew arrives.
The actively for rent exemption only covers a rental that is properly licensed. Which endorsement a house needs, what the DOB housing inspection covers, why an unpaid Class 3 half blocks the license through Clean Hands, and the order that puts a licensed listing in front of DOB inside the 15 day window.
Since October 1, 2025 the statute lists what the vacancy call rests on: neighbor complaints, ANC certification, piled mail, utility notices or low usage, overgrown yards, no furnishings, open to entry, and a catch all. What each looks like from the sidewalk, what the list does not say, and a checklist for reading your own house against it before an inspector does.
Up to 2 tax years while a zoning or historic preservation application is pending. Which applications count, the seams between this exemption, the permit pending half year and active construction where projects fall onto Class 3, how the 5 in 12 cap limits a long project, and how to file it in the 15 day window.
Every exemption draws from one account of 5 tax years in any 12 year period, and the count runs with the property. How to assemble it from the DOB record and the OTR billing history, the three ways owners burn it without noticing, what happens when it is reached, and how to plan a long vacancy against it.
Every vacant building dispute turns on whether anyone lived there during the half year billed. The documents ranked by weight, why a utility account in good standing proves nothing while a bill showing consumption proves a lot, how to build a month by month file for DOB and RPTAC, and what is still recoverable when the tenant and the records are gone.
The probate or title litigation exemption runs up to 3 tax years, but a landlord tenant case is a possession dispute, not a title dispute. Why a holdover tenant keeps the house occupied rather than exempt, the day the exposure starts, and what to file in the 15 day window at each stage from eviction to relisting.
Up to 2 tax years with annual renewal, for a dated event with paper behind it: bankruptcy, a medical event, job loss, disability, fire or disaster. The filings that get denied (an inheritance, an unaffordable renovation, living elsewhere), how the 5 in 12 cap limits the box, and the five steps to file it inside the 15 day window.
A $12,500 half is more than most owners have on hand. What OTR adds after the due date, why an appeal does not pause the bill, how an OTR installment agreement works and what it does not waive, which balance reaches the tax sale first, and the six moves in order that keep a bad tax class from becoming a lien.
Every condo unit is its own tax lot, so DOB designates the unit and the neighbors never see it. How that differs from an empty apartment in a rental building, how a fourth floor unit gets reported and inspected, what the association bylaws do to the for rent exemption, and the order to fix a designated unit.
Guests are not residents. Why a licensed host who lives there is safe and an investor listing with no resident is exposed, why the booking calendar is the wrong reply to a DOB notice, why no exemption category fits a nightly listing, and three arrangements that make the building occupied.
The statute has no landlord grace period. What occupied means for a rental, why a turnover that runs past a couple of months looks vacant from the sidewalk, the for rent exemption and its license requirement, and a turnover calendar from the day the tenant gives notice to the day you register the gap.
The servicer pays whatever OTR bills and the owner learns about it from an escrow shortage letter. Why the servicer will not contest the designation, the occupancy covenant question, what an OTR credit does to the escrow account, and the order to fix it before a refinance or sale.
A furnished house nobody sleeps in is vacant to DOB. Why the notice never reaches an absent owner, which exemption categories fit (hardship, for rent) and which do not, the three occupancy arrangements in order of strength, and a one page checklist for the week before you leave.
An unpaid vacant property half is sold as a lien, not the building. What the purchaser gets, the 6 month wait before a foreclosure case can be filed, how redemption runs through OTR and who you pay, and why redeeming the lien and correcting the designation are two separate jobs.
Up to $1,000 for a first violation, $2,500 for a second, $5,000 after that under §42-3131.10, issued as a DOB notice of infraction. How the notice arrives, why registering does not cost you the exemption, the three defenses that hold up, and the order to handle a fine and a Class 3 bill on the same building.
The vacant property tax is not a residential rule. What changes on a commercial assessment, the 2 tax year for sale or rent exemption, the pending development approval exemption, the tenant build out gap that catches retail landlords, mixed use buildings with tenants upstairs, and why storefronts go blighted faster.
A corrected designation does not send money back on its own. Credit versus refund, the three places the overpaid half gets stuck (owner of record changed, lot ceased, partial correction), why you keep paying while the correction runs, and the refund checklist.
The designation follows the building, not the seller. The two records to pull before you offer, the exemption clocks the seller already used under the 5 in 12 cap, the renovation buyer’s trap, what title will and will not do, and five contract terms that protect the buyer.
DOB mails the 15 day notice to the name and address on the OTR account. The four ways that record goes stale (unprocessed deed, a death, the empty house as the mailing address, an old agent), a two minute check, and how to fix each field before the next letter.
Up to 3 tax years with a valid permit and visible work, the half year bridge for a pending permit application, the 5 year cap that follows the property, and the five ways renovators lose the exemption, starting with the certificate of occupancy.
The registration is annual: $350 to start, $500 to renew under §42-3131.09. Why the renewal is the fee owners miss, what a lapse does to the exemption and the tax class, and how to bring a lapsed registration current without paying more than you owe.
The vacancy clause that narrows a standard policy before the DOB clock even runs, the vacant dwelling policy that replaces it, the conditions carriers and DOB both want, and how a fire claim becomes a hardship exemption filing.
The 15 day petition, the Mayor’s 60 day determination, the status review hearing, and the 45 day appeal to RPTAC. What to file at each step, the evidence that wins, and what happens to the bill while you wait.
Vacant is $5.00 per $100. Blighted is $10.00. The one sentence statutory definition, the conditions DOB actually cites from the sidewalk, and four buildings that show where an empty house stops being vacant and starts being blighted.
The 90 days that make a building vacant by law, the unannounced inspection, the 15 day response window, the DOB to OTR handoff, and the half year bill where the rate finally shows up. A worked calendar and the one point where the owner holds the initiative.
Class 3 and Class 4 are a different rate on the same assessed value, not a penalty on top. The per $100 math on a $500,000 rowhouse, the deductions that fall off, the half year billing cycle, and what one corrected period is worth.
The designation follows the building, not you. How the title company prorates the 5% bill, why an unpaid half can stall settlement, what buyers ask for, and the seller checklist that keeps a correction from landing in the buyer’s account.
Inspectors work from the sidewalk and the alley. The signs of vacancy they note, what pushes a file from vacant to blighted at twice the rate, what “secured” actually means to DOB, and a walk around checklist to run before anyone shows up.
The list is public: the DOB dashboard, Open Data DC, and the OTR tax extract all publish it, and they don’t always agree. How to check an address in two minutes and what to do if your building is on it.
Most denials trace back to four fixable mistakes: wrong category, thin documentation, open violations, or a missed deadline. How to read the denial letter and refile so it holds.
Probate can exempt an inherited house from the 5% vacant tax for up to 3 years, but nothing about it is automatic. The deadlines, the paperwork, and what to do in the first 30 days.
