Plumbing Inspection in Herndon, VA
Roughly 22% of the people who own in Herndon bought since 2018. A normal rate for a town this size, and normal is where the gaps in a standard inspection do their quiet work.
The one-paragraph answer
Turnover in Herndon sits near the middle, with 22% of owner households arriving in 2018 or later. The figure that actually matters is in the standards of practice: a home inspection covers what is visible and operable, and the buried sewer lateral is not.

When Herndon moved in
An average rate hides two different populations: recent buyers with a report, and long-standing owners without one. The advice for the two is not the same.
| Owner households in Herndon | Share of all owners |
|---|---|
| Moved in 2021 or later | 6% |
| Moved in 2018–2020 | 15% |
| Moved in 2010–2017 | 28% |
| Moved in before 2010 | 50% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25038 (tenure by year householder moved into unit), 2023 release. Universe: 32,247 occupied housing units, of which 19,877 are owner-occupied. This counts when the CURRENT occupant moved in, so it measures recent moves as a share of the housing stock — not a rate of sales per year.
What the inspection will not cover
Neither standard requires an inspector to determine water flow, pressure, quality or potability. A report can be entirely clean on a house whose water arrives at a pressure nobody would live with, because that was never a defect it was looking for.

What it is required to cover
Sump pumps are in scope on both standards — InterNACHI for drainage pumps with an accessible float, ASHI for sewage ejectors and sump pumps. Accessible is the whole qualifier. A float nobody can reach is not a float anybody tested.
What is actually covered — because silence in a report means one thing about a covered system and something completely different about an excluded one.
What to do about it
Where a report says a condition was observed but its extent could not be established, that is the sentence to act on. It means the boundary of the inspection was reached, not that the problem is small.
The published standards settle most arguments: excluded, covered, and the separate instruction for everything past the building.
