D.C. Mun. Regs. tit. 9, r. 9-2018
Each appeal decision shall be based upon consideration of the entire record described in § 2020 of this chapter or such lesser portion of the record as may be agreed upon by the petitioner and the Deputy Chief Financial Officer, and approved by the Panel.
Each valuation decision shall include the Panel's determination of the estimated market value of the real property for the applicable tax year.
The Panel shall raise or lower the proposed assessment of any real property for which a petition has been properly filed that it finds to be more than five percent (5%) above or below the estimated market value of that property, except in the case of plain error. In the case of plain error, the assessment shall be clerically corrected.
A Panel shall not order an increase of the assessed value of any parcel of real property above its estimated market value or a decrease of the assessed value of any parcel of real property below its estimated market value solely on the basis of average ratio studies comparing sales and assessments, unless the studies are the primary basis for the assessment or reassessment of the concerned real property in question.
A Panel decision shall include an allocation of total assessed value between the improvements, if any, and the land.
In arriving at its determination, the Panel shall consider the evidence in light of generally accepted principles of valuation and shall take into consideration principles of equalization of assessments of the same or substantially similar properties.
The Panel shall accept any stipulation entered into by the petitioner and OTR which has been forwarded to the Commission and which disposes of an appeal, if the Panel is satisfied that the stipulation was agreed to knowingly and voluntarily by both parties.
Every decision by the Panel shall contain a detailed written statement of the basis for the decision.
Every decision by a Panel shall be signed by each member who participated in the decision and shall indicate whether each participating member agreed with or dissented from the decision.
In the case of an appeal of an annual proposed assessment, a Panel shall render its decision and notify the petitioner and OTR within thirty (30) days in the case of a residential real property appeal and eighty (80) days in the case of a commercial real property appeal.
A written notice of each decision, along with the decision itself, shall be sent to each party by first class mail or electronic mail within five (5) business days after the decision is issued.
The notice of the decision shall include the following text:
"The petitioner has the right to appeal an adverse decision of the Commission to the Tax Division of the Superior Court of the District of Columbia. Payment of all real property taxes, together with interest and penalties (if applicable), before the filing of a petition in the Tax Division of the SuperiorCourt, is a jurisdictional prerequisite to the appeal."
Every decision of the Commission shall be maintained by the Commission for three (3) years and shall be made available for public examination and photocopying at the expense of the requester, subject to the confidentiality provisions of D.C. Official Code § 47-821(d)(2)(A) and (B) (2012 Supp.).
Each decision of the Commission shall also be placed on the website of the Commission, subject to redactions based on the confidentiality provisions of D.C. Official Code § 47-821(d)(2)(A) and (B) (2012 Supp.).
