What kinds of animals can be emotional support animals in New Hampshire?

What the law says

HUD FHEO Notice 2020-01: "An assistance animal is not a pet" and "the species of the animal is a factor a housing provider can consider" — with "common household animals" (dogs, cats, small birds, rabbits, etc.) typically not requiring detailed justification, while "unique animals" may require additional information about how the animal helps.

In plain language

Federal guidance applied in New Hampshire treats common household animals — dogs, cats, small birds, rabbits, hamsters, gerbils, fish, turtles, other small domesticated animals — as the default for ESA accommodations, with housing providers generally not requesting additional information about why the species was chosen. For "unique animals" (reptiles other than turtles, barnyard animals, monkeys, kangaroos, etc.), HUD's guidance describes a more searching inquiry into whether the specific animal is necessary. Whether a particular animal in a particular building would be considered reasonable in New Hampshire is fact-specific.
