What is likely happening
Parapets are exposed on both sides, so they deteriorate faster than the walls below. Leaning, cracked mortar, or loose coping stones can fall to the street.
What you can safely check
- From the roof, look along the parapet line for lean or gaps.
- Keep people away from the base on the street side.
What an inspector will look at
- Plumbness and stability
- Mortar and coping
- Flashing and water entry
Does this affect compliance?
NYC requires an annual parapet observation (Local Law 126); other cities cover parapets under facade inspections.
When it becomes urgent
Urgent if anything is loose or visibly leaning.
