Different approaches to the study of small accommodation enterprises emanating from outside of hospitality are identified and a new hospitality-derived approach described: the commercial home enterprise (CHE). The commercial home sector is a numerically important yet often neglected part of the commercial accommodation sector and is briefly described and associated statistical problems highlighted. A critical review is undertaken of key studies concerning the commercial home host, identified as an integral part of the commercial home product, and inferences drawn out. Finally, broad characteristics of the CHE are summarised and areas for future research suggested
