Good to know

  • Every principal occupant of a home or business within 600 ft of the coop or run must consent. Consent is assumed if no written objection arrives within 15 days of the Board's notice.
  • Poultry may not run or fly at large.
  • Coops must be kept dry, ventilated and cleaned daily.
  • A license can be denied if the birds would harm the health of the neighborhood.

What about ducks?

Yes, with conditions. Mountain Lakes' rules cover poultry, birds or fowl of any kind, so ducks face the same 60-foot setback and, within 600 feet of a neighbor's house, a Board of Health license and neighbor consent.

§§ 257-1, 257-5; § 249-15: "No person shall keep or maintain live poultry, birds or fowl of any kind, other than song birds, rabbits, hares, guinea pigs, or animal of any kind, other than dogs and cats, within 600 feet of any dwelling house" Duck coops we build.
