E 9-1-1 Sign Law

Dutchess County law requires uniform signs when displaying addresses, so all properties can be easily identified by emergency responders. Property owners are responsible for affixing the assigned E-9-1-1 address number, so it is visible from the road.

For Residences

  • Numbers must be at least 3 inches in height, durable, and clearly visible. Reflective materials are even better.
  • Numbers should be of a contrasting color from the background on which they are mounted. For example, dark numbers on a light background.
  • If the home is more than 50 feet from the road or the entrance to the building is not visible from the road, numbers should be placed on a post along a walkway, driveway, or other location, so the address number is visible from the road from any direction and a second set of numbers should be placed on the building.

For Commercial & Industrial Buildings

  • Numbers must be at least 4 inches in height and displayed over the main entrance.

For Grouped Establishments

  • For groups such as apartments, town houses, shopping centers, and others where only one E-9-1-1 address number is assigned, numbers should be displayed at the main entranceway and should be at least 4 inches in height.
  • Individual unit numbers/letters should be displayed on, above or to the side of the main entrance to each unit, apartment, suite, etc.
