Permits & Inspections

    During the temporary City Hall closure, we are trying our best to accommodate our permitting process electronically.

    All inspections will be performed virtually, when possible. 

    For building, construction and trade permits, email

    For utility, sediment control, stormwater and all other general public works permits, email

    For fire protection systems, email

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.
