Since the renovation of the house in 2001, very little has been spent on upkeep of 24 Sussex Drive, leaving parts of it worn and outdated, including the heating and cooling systems, wiring, and roofing. On May 6, 2008, the Auditor General reported that the house was in poor condition and needed about $10 million in repairs and upgrades, which would require at least 12 to 15 months of "full access" to complete. In October 2015, Bryan Baeumler estimated $15 million might be necessary to properly renovate the residence. The NCC is devising a plan for major renovations, asserting such a project will require approximately 18 months.
