@nycmusic If there are vulnerable adults or seniors in the house, the report goes to Adult Protective Services, if there are children, to Child Protective Services - either in your county or state. A social worker investigates, and can order a cleanup, removal of the vulnerable person, even bring in officials to condemn the property if beyond saving.
These measures are for extreme situations, not just messy houses that may not meet my standards or yours. Examples - rotting garbage, rodents, pet feces, papers piled near/on gas stoves or space heaters, multiple exits blocked, non-working plumbing, water or heat.
