This article focuses on the relevance of a digital approach as BIM in the particularly dynamic and diversified renovation sector, mainly driven by micro enterprises (μEnt). The state of the art shows that few scientific references are devoted to this subject and that the technologies and tools available, which are often very costly, have not demonstrated their profitability (and feasibility) for this business typology. An extensive literature review is used to define the scope and terms of the field of renovation. It demonstrates the areas of interest for a BIM approach and highlights some gaps that should be filled with future works. It is necessary to better map the different observable renovation processes, as well as adapt or develop an appropriate BIM maturity measurement tool for this renovation sector and for μEnt.
