Permits & Inspections

Both commercial and residential properties in the City of Rockville are required to obtain permits before starting construction projects related to electrical, plumbing, mechanical, structural work and more. 

Work in or adjacent to the public right-of-way or impacting trees or stormwater facilities also requires permits.

Most permits also require one or more inspections before work is considered complete and final. Construction in Rockville is regulated by the city’s Municipal Code and Charter and Maryland Fire Prevention Code, among other codes and regulations.
