Quick answers
- 2025 VA legislation adds septic inspection expectations around transfers — confirm current realtor/VDH guidance for your county.
- Most critical for rural and fringe lots, not typical Arlington row homes on public sewer.
- Plumbing on the house side (ejectors, grinders, filters) still needs a licensed plumber.
- We coordinate honestly when septic specialists must lead versus when house plumbing is the bottleneck.
When to use this guide
Use this when buying or selling a well/septic property in Fauquier, western Loudoun, or similar VA counties, or when a listing checklist suddenly mentions septic inspection.
Why the law changed
Failing septic systems create health and Bay-watershed risks. Transfer-time inspection rules surface problems before they become the next owner’s emergency.
How this interacts with house plumbing
Ejector pumps, grinder pumps, and laundry/fixture loads affect septic longevity. We diagnose the building plumbing; licensed septic professionals handle field/tank scope.
Customer plus
Fewer post-closing surprises, clearer repair sequencing, and a local plumber who already works the rural expansion map.

Failure modes to avoid
Ignoring septic until the week of closing
Repair timelines blow up deals. Inspect early on rural contracts.
Asking a plumber to “just certify the septic field”
Wrong license lane. We will tell you when a septic contractor must lead.

FAQs
Does this apply inside Arlington County?
Arlington is overwhelmingly public sewer. The legislation matters most for rural/septic properties — confirm with your agent for the specific parcel.
Can you inspect my septic tank?
Septic field/tank inspections are specialist work. We handle house-side plumbing that ties into the system.
Where do I book a pre-listing plumbing check?
See our code compliance & safety inspection Act page for sewer/water-heater/flue package scoping on applicable homes.
