D.C. Mun. Regs. tit. 10, r. 10-B6609
DMPED shall deem a real property ineligible for the tax abatement if it determines that the owner or the real property fails to meet the conditions in the tax abatement certification, in this chapter, or in the D.C. Official Code §§47860.01 - .04 during the tax abatement period.
If at any time during the tax abatement period DMPED determines that the real property has become ineligible for the tax abatement, DMPED shall transmit to OTR and the owner a letter of termination, setting forth the reason(s) for the termination and the date on which the termination took, or shall take, effect.
If DMPED determines that the real property has become ineligible for the tax abatement, DMPED may, in its sole discretion, provide the owner a period to cure the real property's ineligibility. If the owner cures the property's ineligibility during the period to cure, DMPED may, subject to D.C. Official Code §§ 47-860.03(b), restore the tax abatement. The tax abatement shall not be provided for the period during which the real property was ineligible, and the period of cure shall not toll the 20-year period set forth in D.C. Official Code §§ 47-860.03(a)(1) and §§6605.7 of this chapter.
The real property shall be ineligible for the abatement on the first day of the tax half year following the date when DMPED determined the real property to be ineligible.
