Development Pipeline

Pipeline of Approved Development

Montgomery County, Maryland

The Montgomery Planning Department tracks the residential and non-residential development Pipeline for Montgomery County (Rockville, Gaithersburg, Laytonsville, and Poolesville included*). The Pipeline is an inventory of development projects that have been approved by the Montgomery County Planning Board but not completely built. This inventory covers unbuilt dwellings units and unbuilt non-residential building gross square footage.

Residential dwelling units are further characterized into single-family dwellings and multi-family dwellings. Non-residential gross floor area is characterized into the number of jobs and gross floor area for office, retail, industrial, and other non-residential types associated with the project.

* Rockville, Gaithersburg, Laytonsville, and Poolesville perform their own planning functions and have provided their pipeline data.
