The Warner family occupied the house until 1967, when the property was purchased by the Washington County Board of Education as the site for Clear Spring Middle and High Schools.

Plumb Grove was placed on the National Register of Historic Places on December 7, 2011. It is owned by the Clear Spring District Historical Association. It has been restored and is open to the public.
