Alan Kidd, a 52-year-old former township councilman, was working on the house his grandmother lives in when the mishap occurred on a busy stretch of Franklin Turnpike near Stephens Lane, Mayor John Roth told Daily Voice.
A companion at the scene told police that they both were "doing painting and repairs to the second level of the two-story home from ladders," Police Chief Stephen Jaffe said. "Although he was not in visual contact, he heard a loud noise.
"Upon investigating he discovered the victim on the ground as well as the ladder that the victim had been on nearby."
Mahwah EMS and paramedics arrived and took over medical care, the chief said.
Kidd was taken to Hackensack University Medical Center by ambulance after an initial standby call for a medical chopper was cancelled.
