The Montgomery Planning’s Development Applications and Regulatory Coordination (DARC) Division manages the timely review of development applications for consistency with adopted master plans as well as impact on the environment, quality of design, compatibility with neighboring uses and the availability of public facilities (water and sewer, transportation, schools). The application process involves several stages, including sketch, site and preliminary plans, that require Planning Board approvals. This review process can take up to 120 days.
Once the plans for the development project are approved by the Planning Board, the applicant must apply for a building permit at Montgomery County’s Department of Permitting Services (DPS). A building permit is required for all new construction, additions, alterations and changes of use in Montgomery County and municipalities, with the exceptions of the City of Rockville and the City of Gaithersburg.
