Multi-unit inspection: connect building condition with investment reality.

A multi-unit building must be read as a whole: envelope, structure, common systems, units, deferred maintenance and occupancy conditions may influence each other.

Define the scope before the visit

  • Number of units, common areas and technical rooms included.
  • Access to roofing, basements, service spaces and equipment.
  • Available documents: revenue does not replace physical condition; invoices, maintenance contracts and former reports are more useful technically.

Every unit or a sample?

  • Inspecting every accessible unit generally provides a stronger picture. Sampling may be agreed for larger properties, but it necessarily limits what can be concluded. The choice must be explicit in the scope and report.

Think in systems

  • A stain in one unit may relate to roofing, façade, common plumbing or interior use. The analysis identifies plausible relationships without claiming a concealed cause has been confirmed without evidence.

For investors

  • A separate cost assessment may complement the technical report when CAPEX planning is required. Separating technical observation from financial estimation makes assumptions clearer.
