Knowing what you own is the whole job.
Boilers, lifts, roofs, AHUs, pumps, panels, doors. Residention keeps each one with its place in the building, its condition, its history, its cost of ownership and its renewal case — and refuses to let a declared life pretend to be a measured one.
Most asset registers are inventories: a list that was true on the day it was imported. What decisions need is different — the condition someone actually observed, the failures actually recorded, the money actually spent and how much of the estate those readings cover.
Residention treats every one of those as a separate, dated fact with its own provenance. That is what makes a replacement case defensible: not a confident number, but a number whose working can be opened.
