  • Fire Protection Equipment and Systems.  Includes fire alarm and detection, fire pump, fire sprinkler, standpipe, underground fire line, smoke control, fire protection supervisory, and alternative fire-extinguishing systems. For clarification about installation permit requirements related to periodic maintenance and simple repairs to defective existing fire protection systems and equipment, please consult the following letter to community and industry:

Installation permits were previously known as construction permits; however, the title was changed to "installation permit" to avoid confusion with building and trade permits issued by Land Development Services (LDS). Once issued, installation permits allow the permit applicant (i.e., licensed contractor) to install or modify equipment and systems regulated by the Virginia Construction Code (VCC) for which a permit and/or approval is required, in addition to applicable sections of the Fire Prevention Code and the water and fire regulations section of the Public Facilities Manual (PFM).

Installation Permit Fees. For a complete list of permit application and plan review fees associated with installation permits, consult the billable services and fees section of our web site.
