Subdivision Regulations Rewrite

The Montgomery County Planning Department invites community members and developers to review the newly approved rewrite of Chapter 50 of the Montgomery County Code that governs the subdivision of land in the county.

This is the most comprehensive rewrite of the Subdivision Regulations in 50 years and was undertaken at the direction of the Montgomery County Council. It responds to the county’s newly released Zoning Ordinance and seeks to clarify and streamline the review and approvals process for new subdivisions.

The Subdivision Regulations include the application requirements for subdividing property, as well as requirements for adequate public facilities and improvements to lots based on the impact of subdivision.
