The Virginia Uniform Statewide Building Code requires a construction permit before any of the following work takes place: Constructing, enlarging, altering, or demolishing a building or structure.  Installing or altering any equipment regulated by code.  In general, a building permit is required for all additions, all alterations, all decks, all garages, retaining walls over 3 ft., and detached sheds over 256 sq. ft. or more than one story.  Any additions or alterations to electrical, plumbing, or mechanical systems would require separate  permits.

All contractors doing work within the town of Herndon must obtain a license from our finance department if the accumulated cost of work is over $25,000 in a calendar year. A business license must be obtained prior to applying for a permit.

In addition, all outstanding property taxes, levies, and fees must be paid to the finance department prior to applying for a permit.

Emergency permits (water service, electrical service, heat, etc.) can be applied for prior to meeting the finance requirements.

It is strongly encouraged that all applications and plans be submitted via email. Please apply by emailing all applications and plans to: buildinginspections@herndon-va.gov
