The governing body of every county and city shall provide courthouses with suitable space and facilities to accommodate the various courts and officials thereof serving the county or city; within or outside such courthouses, a clerk’s office, the record room of which shall be fireproof; a jail; and, upon request therefor, suitable space and facilities for the attorney for the Commonwealth to discharge the duties of his office. The costs thereof and of the land on which they may be, and of keeping the same in good order, shall be chargeable to the county or city. The fee simple of the lands and of the buildings and improvements thereon utilized for such courthouses shall be in the county or city, or jointly in a county and a city, and the governing body of the county or city may purchase so much of such property, as, with what it has, may be necessary for the purposes enumerated or for any other proper purpose of the county or city. However, any portion of the property owned by a county and located within a city or town and not actually occupied by the courthouse, clerk’s office, or jail may be sold or exchanged and conveyed to such city or town to be used for street or other public purposes. Any such sale or exchange by the governing body of a county shall be made in accordance with the provisions of § 15.2-1800. The amendments contained in Chapter 90 of the 1986 Acts of Assembly shall not apply to the City of Virginia Beach.
