Mixed Hereditament

Mixed hereditament, means a hereditament which is not a domestic hereditament but in respect of which it appears to the rating authority or is determined that the proportion of the rateable value of the hereditament attributable to the part of the hereditament used for the purposes of a private dwelling or private dwellings is greater than one-eight. Any part of the hereditament used for the letting of rooms singly for residential purposes, whether by way of tenancy or licence and with or without board or other services or facilities, or used as sites for movable dwellings, is to be treated as used for purposes other than those of a private dwelling or private dwellings, Halsbury's Laws of England, 4th Edn., Vol. 39, para 192, at p. 169.
