Va. Code § 36-72
Industrialized building units and mobile homes, because of the manner of their construction, assembly, and use and that of their systems, components, and appliances, including heating, plumbing, and electrical systems, like other finished products having concealed vital parts, may present hazards to the health, life, and safety of persons and to the safety of property unless properly designed and manufactured. In the sale or rental of industrialized building units and mobile homes, there is also the possibility of defects not readily ascertainable when inspected by purchasers or users or by the local building official. It is the policy and purpose of the Commonwealth to provide protection to the public against those possible hazards and to promote sound building construction, and for that purpose to forbid the sale, rental, or use of new industrialized building units and mobile homes that are not so constructed as to provide reasonable safety and protection to their owners and users and involve reasonably sound building practices. It is further the policy of the Commonwealth to minimize the unique problems presented by a lack of uniform standards and inspection procedures affecting the mass production of housing and to hereby declare its intention to (i) encourage the reduction of construction costs and (ii) make housing more feasible for all residents of the Commonwealth.
