Virginia requires septic disclosure on all property transfers (March 2026)
As of March 2026, Virginia law requires sellers to disclose the maintenance history and compliance status of any on-site sewage system (OSS) during property transfers. Buyers and their real estate agents are specifically seeking inspectors licensed as On-Site Sewage Professionals (OSSPs) — the state-designated credential issued by the Virginia Department of Health. Without an OSSP evaluation, deals can be delayed or fall through entirely. Inspections typically cost $400–$800 depending on system type and access requirements. Fairfax, Prince William, and Loudoun counties see the highest volume of real-estate-driven inspections. If you are under contract in Virginia, request an OSSP-licensed inspector specifically — other certifications do not satisfy the disclosure requirement.
