Pakubuwono X during his reign spent a large amount of money on upgrading the Juru Kunci administration buildings in Imogiri village, the Mosque at the foot of the stairs, the stairs and the Graveyard in general. He also constructed the Girimulya section as well. Hamengkubuwana VIII in the process of constructing Saptorenggo in the 1920s also conducted repairs on the earlier structures that required repairs. Various Suharto-era bureaucrats and army personnel with connections with branches of earlier rulers contributed to a number of roof renewals and other renovations. The Indonesian Government contributed to a project that rehabilitated the yard known by its split gate – the Supit Urang – under the auspices of the archaeology service and appropriate agencies in the 1980s. In the 1990s the main gate into Sultan Agungan also required repairs. The 2006 earthquake in the region saw considerable damage to the complex. It is not known yet to what extent repairs and renovations are possible again, and from where the funds will emanate.

Some immediate families of rulers were also buried in Imogiri, but not all; this was dependent upon each ruler's preferences. Printed lists of the burial plots within the royal graveyard complex are maintained for Imogiri to provide guidance for researchers looking for a specific grave site. This process is sometimes complicated by the multiple names some individuals were known by during their lives. Sections Each section is a walled compound with three internal sections –
