The Loudoun County Board of Supervisors has adopted a new zoning ordinance, completing a nearly four-year process that included extensive public engagement with a broad range of stakeholders. The new Loudoun County Zoning Ordinance was adopted by the Board following a public hearing December 13, 2023. It is effective immediately and replaces the previous ordinance known as the Revised 1993 Zoning Ordinance.
The Mountainside Overlay District (MOD) Story Map is one companion tool that provides information and mapping that complements the Loudoun County General Plan and Zoning Ordinance. The MOD was established to minimize disturbance to the critical ecological resources in the county's mountainside areas.
