Developers, architects, lawyers, realtors, tax assessors, land owners, and others in the land use business often require definitive authentication of zoning classification of property for due diligence purposes. A Certification of Zoning is used as a means of gaining official written recognition of zoning from the DC Government.

A Certification of Zoning can be obtained by submitting a request through the Interactive Zoning Information System (IZIS)(link). The response will be provided within 10 business days.

Per OZ procedure, the request must include the name and address of the person making the request, the square and lot numbers of the property, and the address of the property. This process involves a $50 fee and must be accompanied by a PDF copy of a plat (no larger than 11" x 17") of the property, prepared by the DC Surveyor or an engineer licensed in the District of Columbia.

The Director of the Office of Zoning has the option to request additional information from the person requesting the certification so as to clarify the location of the lot, the dimensions of the lot or the location of any improvements thereon. The certification will bear the Director's certification of the zoning district which the official records of the Zoning Commission show as applicable to the particular lot and square. The Director of the Office of Zoning may waive any portion of these rules for good cause shown
