Vienna: town water, county building official

Who does what here

Water	The Town of Vienna operates its own system. Under the owner agreement, your share of the water pipe starts past the meter yoke. source
Sewer	Under the same agreement the owner maintains the sewer connection from the main to the building. The town's pages left open who operates the mains. source
Permits	Fairfax County acts as building official; the Town adds a street-cut permit where work opens its streets. source
Licensing	Contractor license classes follow job value under state law; the county, which inspects, can say what it requires. source
Lead pipes	We could not confirm a Town of Vienna lead service-line inventory from its pages. Ask the town's public works department. source

A town whose water crosses its own line

Vienna is one of the few places on this map where the water bill and the street address can point to different governments. The town says it serves nearly 5,600 customers and that about one-third live outside Town limits. A house in unincorporated Fairfax County may therefore get its water from Vienna, while a house inside the town would not need a county supplier. The county's own water-service map shows Vienna as a supplier beside Fairfax Water. Neighboring McLean and the Annandale sheet carry the same warning from the other side.

What the agreement says

The town's water and sewer agreement splits the pipes by a defined point. Past the meter yoke, the water pipe is the owner's. The sewer connection from the main to the building is the owner's too. The agreement is the town's own document, and it is the one to quote if a dispute arises. Read the agreement itself before assuming your boundary is where a neighbor's is.

Two offices for one project

The town's page lists Fairfax County as the building official, so plan on the county's PLUS portal and its inspectors. The town separately issues a street-cut permit when work opens its right of way. Digging in a street without both, where both apply, is a problem for the contractor and the owner. The county's rules for inspections are in permits by place.

For a pipe under a road, trench work belongs to licensed contractors, and 811 comes first. See digging and 811.

What the map can't tell you

• Whether your address is inside the town or just a Vienna mailing address. Only the tax record settles it.
• Who operates the sewer mains on your street. The town's pages did not confirm it for us.
• Whether a Vienna-supplied customer outside the limits is billed or governed differently. We found nothing that said.
• The condition of your service line, since no Vienna inventory was available.

Check your own address

1. Look at the top of your water bill: does it say Town of Vienna or Fairfax Water?
2. Pull the owner agreement the town links, and mark where the meter yoke sits on your lot.
3. Call the Town of Vienna public works office before any work that touches the street, and ask about the street-cut permit.
4. Ask Fairfax County's Land Development Services which permit your project needs, and book the inspection.
5. Gas smell: leave first, then call 911 and 844-927-4427 from outside.
