Yaumati Theatre has been a Grade II historic building since December 1998. The implications of this is that all alterations on the building have to comply with a set of heritage conservation requirements in order to guide its future use and protect its cultural significance, including long term development, conversation and maintenance plans for the building. The Heritage Impact Assessment (HIA) for Yaumati Theatre was carried out by Architectural Conservation Office on behalf of the Architectural Services Department in October 2008, with the agreement of both Cantonese Opera Advisory Committee and the Antiquities and Monuments Office of HKSAR Government.
