Can you keep chickens in Township of Plainsboro, NJ?

Plainsboro allows keeping fowl only as a farm use in its R-200 Rural Zone, not in ordinary residential zones, with shelters set well back from lines and neighbors.

The rules at a glance

Chickens allowedYes, with conditions
HensNo hard cap for small flocks (100+ fowl triggers larger setbacks)
RoostersNot specified
PermitAllowed as a farm use in the R-200 zone (no separate poultry permit named)
Coop setbackFowl shelter at least 30 ft from side/rear lines and 100 ft from an adjoining dwelling
Lot sizeR-200 Rural Zone, roughly 0.81-acre minimum lot; fowl not a permitted use in standard residential zones
DucksSame rules as chickens

Good to know

  • Farm and agricultural activities, including small animal and livestock raising, are a permitted use only in the R-200 Rural Zone.
  • Standard residential zones do not list fowl-keeping, so it isn't allowed there.
  • Larger flocks (over 100 fowl) face 90-200 ft setbacks.

What about ducks?

Only in the R-200 rural zone. Plainsboro's farm rules cover 'fowl of all kinds,' so ducks are treated like chickens: allowed only as a farm use in the rural zone, with shelters set well back.

§ 101-25; § 101-30: "shall be erected or used for the shelter of more than 100 head of fowl of all kinds or more than two head of other farm livestock." Duck coops we build.
