IMPORTANT NOTICE: Effective Monday, September 16, 2019, the Office of Zoning and Administrative offices will be temporarily relocated to 751 Twinbrook Parkway, Rockville, Maryland (next to Meadow Hall Elementary School). All OZAH hearings will be held in a temporary hearing room at the new Twinbrook location. OZAH’s telephone number and mailing address will remain the same. Deliveries and in person submissions should be sent to the new address. Thank you for your patience.



The mission of the Office of Zoning and Administrative Hearings is to conduct due process hearings in land use and other administrative matters in a manner that protects the rights of the participants, provides a complete record in each case, results in a thorough and balanced report or decision and serves the public interest.

Duties and Responsibilities

The principal responsibility of the Office of Zoning and Administrative Hearings (OZAH) is to conduct due process administrative hearings on land use cases and other matters. These include applications for rezonings, development plan amendments and floating zone plan amendments; all conditional use applications (formerly known as special exceptions); and accessory dwelling unit objection and waiver cases arising out of the Department of Housing and Community Affairs. OZAH also presides over matters referred for hearing by the Human Rights Commission, the Commission on Common Ownership Communities, the County's Merit System Protection Board, the Office of Consumer Protection, and the Office of the Chief Administrative Officer in appeals arising under the County's Prevailing Wage Law. 


Accessory Dwelling Units - New Regulations Effective December 31, 2019

Montgomery County has created a new process for obtaining waivers from on-site parking requirements for Accessory Dwelling Units.  It is designed to streamline the licensing process, making it easier for owners to pursue this option and increase the supply of affordable housing in the County.

Class 3 accessory dwelling unit licenses are issued by the Department of Housing and Community Affairs (DHCA), Licensing and Registration. If DHCA turns downs a license application because of a failure to meet on-site parking requirements you may file this Waiver Form seeking a waiver from OZAH.

Visit the Department of Housing and Community Affairs page for more information on the process of applying for an accessory dwelling unit license.

Weather Policy

When Montgomery County Schools are closed due to the weather, OZAH hearings will not be held. When Montgomery County Schools announce a late opening, OZAH hearings will be correspondingly delayed.
