The word family as per BDA rules means, in relation to the person viz.: wife, husband, parents, children, sisters, brothers wholly dependent on him. In the light of the above, his son who is not dependent on his father is eligible for allotment of site by BDA. But if the wife owns a BDA or non-BDA site or house, the husband is not eligible for allotment. Likewise if the husband owns a site or house, the wife is not eligible.
