What is the hoarding cleanup severity scale?

Hoarding scenes are rated on the ICD Clutter Hoarding Scale from Level 1 (normal household) to Level 5 (severe structural hazard and biological contamination). Levels 3-5 require biohazard protocols — PPE, bulk waste removal, pest remediation, and frequently unattended-death-grade decontamination. Per IICRC S540 and ICD Clutter Hoarding Scale.
