RSA 147:6: Removal Without Notice.

When the owner of a building, vessel or enclosure is unknown to the health officers, or does not reside in town, and the same is unoccupied, or the occupant is, in their opinion, unable to remove the same, they may, without previous notice, immediately cause the nuisance or other thing by them deemed injurious to the public health found therein to be removed or destroyed.
