The DC Vacant Building Response Form is what you send back to the Department of Buildings (DOB) after an inspector flags your property as potentially unoccupied. You identify the property, pick one of three statuses — vacant, occupied, or exempt — attach the documents that support your choice, and file the form through the DC Citizen Access Portal or by email. The status you select determines your tax classification for the year, so the paperwork matters more than a routine form usually would.
The Three Status Choices
The form gives you exactly three options, and each carries different consequences and different documentation.
- Yes, my property is vacant. You accept the Class 3 tax rate and pay a $250 registration fee with your response. The registration renews annually at the same $250 until the property is occupied or demolished.1Department of Buildings. Vacant Buildings Response Form2D.C. Law Library. District of Columbia Code 42-3131.09 – Fees
- No, my property is occupied. You dispute the inspector’s finding. Attach water bills and other utility records covering the period the building became occupied. Commercial properties also need a Certificate of Occupancy.
- My property is exempt. You claim a statutory exemption. If approved, your tax rate stays unchanged for the fiscal year. Each exemption category requires its own documents.
Choosing the wrong option or submitting weak documentation can lock you into the vacant classification while you fight it on appeal, so match your choice to what you can actually prove.
Filling Out the Form
The form has three steps.
Step one is property and contact information. You need the Square, Suffix, and Lot (SSL) numbers, which appear on your DC real property tax bill, plus the property address, your name, phone, email, and mailing address. If a property manager or attorney is handling the response, their information goes in the agent fields.
Step two is a certification. You sign a statement confirming you have checked the DOB Agency Performance Dashboard and do not owe the DOB any outstanding money. The form warns that a false statement is a criminal offense under DC Code § 22-2405, so treat the signature seriously.1Department of Buildings. Vacant Buildings Response Form Before you sign, email DOB.civilinfractions@dc.gov to confirm your account is clear.
Step three is where you select your status and attach the supporting documents. This is the choice that drives the rest of the process.
Documents for Each Exemption
If the property is empty but you believe it qualifies for an exemption, the form lists several categories. Each has its own proof requirements and its own time limit under the DC Code.
- Active construction or renovation. Attach a valid, active building permit. The permit must have been issued, renewed, or extended within 12 months of the required registration date. The exemption lasts up to three tax years.3D.C. Law Library. District of Columbia Code 42-3131.06a – Exemptions
- Actively marketing for sale or rent. Attach your listing agreement with the real estate agent’s contact information and an MLS or MRIS electronic listing. Single-family homes get half a tax year; multifamily, commercial, or mixed-use buildings get two tax years.3D.C. Law Library. District of Columbia Code 42-3131.06a – Exemptions
- Probate or title litigation. Attach the current deed, a Letter of Assignment showing your authority over the property, and court documents proving the case is active. This exemption runs up to three tax years from the filing date.3D.C. Law Library. District of Columbia Code 42-3131.06a – Exemptions
- Pending development board application. Attach a copy of your filed application for a hearing before the relevant board or commission.
- Economic hardship. The Mayor can grant this in extraordinary circumstances. The DOB publishes a separate hardship checklist and Administrative Bulletin. Ask for those documents when you file.
Every exemption also requires that the building meet DC’s vacant property maintenance standards. It must be weather-tight, structurally sound, free of debris and graffiti, and secured against unauthorized entry. Missing or broken windows and doors have to be covered with half-inch CDX plywood, screwed or bolted in place. The grounds must be clean and sanitary.4D.C. Law Library. Subchapter II – Registration of Vacant Buildings A building that qualifies for an exemption on paper but fails the maintenance requirements will not get one.
How to Submit
You have two submission options. The faster route is the DC Citizen Access Portal at citizenaccess.dc.gov, which lets you file electronically. The alternative is to email the completed form and all attachments to dob.blight-economichardship-appeals@dc.gov.5Department of Buildings. Vacant Buildings Save your confirmation either way. The portal generates a digital receipt; email leaves a sent-folder record. If a dispute later comes up about whether you responded, that confirmation is your evidence.

What Happens After You Submit
The DOB reviews your form and supporting documents and may send an inspector back to verify your claims. You then get a determination letter classifying the property as occupied, vacant, or blighted.
If the DOB designates your building as vacant and you disagree, you have 15 days from the date of that designation to petition the Mayor for reconsideration.7D.C. Law Library. District of Columbia Code 42-3131.15 – Administrative Review and Appeal The Mayor has 60 days to issue a final determination. Silence during that window counts as a denial.
After the final determination, or after the 60-day clock runs out with no response, you have 45 days to file a formal appeal with the Real Property Tax Appeals Commission for the District of Columbia.7D.C. Law Library. District of Columbia Code 42-3131.15 – Administrative Review and Appeal The Commission cannot extend that 45-day deadline. You also cannot skip the reconsideration step; the Commission will not accept an appeal until reconsideration has been decided or denied by silence.
What Is at Stake
A vacant designation moves your property into Class 3, currently taxed at $5.00 per $100 of assessed value. A blighted designation, reserved for vacant properties with hazardous conditions or serious code violations, pushes it into Class 4 at $10.00 per $100.8DC Office of Tax and Revenue. Real Property Tax Rates Standard residential property (Class 1) is taxed at a fraction of those rates, so the jump is substantial. The elevated rate stays in effect until you show the property is occupied again or fully remediated.
Ignoring the form carries its own penalties on top of the tax reclassification. Owners who fail to register, submit false information, or refuse to allow an inspection face civil fines of $1,000 for a first violation, $2,500 for a second, and $5,000 for each subsequent violation.9D.C. Law Library. District of Columbia Code 42-3131.10 – Penalties for Noncompliance Combined with the Class 3 or Class 4 rate, an unanswered response form can turn into a serious bill inside a single tax year.
