Buying or Selling a Home With a Septic System in Virginia

Sourced from HB 2671, 12VAC5-610, 12VAC5-613, 9VAC25-830 and the Code of Virginia — last checked August 2026.

Start With What’s Actually Required

Nothing in Virginia law mandates a point-of-sale septic inspection. HB 2671, effective July 1, 2025, sets standards for what an inspection must contain when one is requested — it doesn’t require anyone to request one.

See our full explanation of HB 2671, including why several widely-read sites get this wrong.

What usually decides it is financing. FHA and VA lenders typically require evidence of a functioning system. Conventional lenders often escalate to a septic evaluation if a home inspection raises concerns. Cash purchases carry no requirement at all.

The Bedroom Count Question

If an inspection does happen, HB 2671 requires the inspector to determine the advertised number of bedrooms and the designed system size from local health department records.

A home marketed as four bedrooms on a system designed for three is exactly what that requirement is built to surface. If you’ve finished a basement or converted a room, check the permit before a buyer’s inspector does.

CBPA Pump-Out Records

If the property is in a Chesapeake Bay Preservation Area — which covers most of eastern Virginia — there’s a legal requirement to pump at least every five years, and localities track compliance.

A buyer’s agent who knows the market will ask for those records. Not having them isn’t fatal, but it’s a negotiating point you’d rather not hand over. A $400 pump-out before listing is cheaper than the concession it prevents.

See our CBPA guide, including the certified-inspection alternative some localities accept.

If It’s an Alternative System

Buyers should ask for three things:

The O&M manual. Required under 12VAC5-613-170 and written, by regulation, to be understandable to any potential owner. It documents design limits, components, site layout and maintenance schedules.

The operator’s log. Under 12VAC5-613-140 the seller must make a reasonable effort to transfer it to you. It’s the maintenance history.

The application date. Whether it was filed before or after December 7, 2011 determines whether renewable operation permits and laboratory sampling apply.

Sellers: the log transfer is an obligation, not a courtesy. And an operator relationship is a condition of the permit — a lapsed one is a problem the buyer inherits.

What Every Buyer Should Ask

Is it conventional or alternative? The obligations differ enormously.

What records does the local health department hold? Permits, as-built drawings, prior evaluations. On older rural properties there may be little.

How many bedrooms is the system designed for?

Is the property in a CBPA, and is pump-out compliance current?

Where are the tank, drainfield and reserve area? You need this before planning a shed, pool or driveway.

What would a replacement cost here? An inspection tells you the system works today. On a Piedmont clay lot or a Coastal Plain property with a high water table, a replacement could mean an alternative system, which costs materially more than a conventional field and adds ongoing operator costs. Ask the health department what the site would support now.

For Sellers

Getting ahead of it costs less than reacting.

Pull your permit file from the local health department. Confirm the bedroom count matches. Pump the tank and keep the receipt. If you’re in a CBPA locality, gather five years of pump-out records. If you have an AOSS, locate the O&M manual and the operator’s log.

A pre-listing inspection is a modest, predictable cost and means you find out about problems on your own schedule rather than during the buyer’s due diligence period, when time pressure works against you.
