Relates to the appointment of fire chiefs and assistant chiefs

S 500 allows fire districts to appoint fire chiefs and assistant chiefs who are employees of the district, expanding eligibility beyond previous restrictions. It requires nominees to be current members of the fire department and permits the board of fire commissioners to mandate that officers reside in the district. The bill establishes an annual nomination process (typically in April, though districts may adopt resolutions to change the date) and prohibits individuals convicted of arson from holding these positions. This change affects fire department leadership appointments across New York State fire districts.
