Housing should be placed in the center of the most open spot available, about 30-120 feet from human housing. There should be no trees taller than the martin housing within 40 feet, preferably 60 feet. Generally, the farther the housing is placed from trees,the better. In the southern half of their breeding range, martins are less particular about house placement. Southern landlords can sometimes place housing within 15-20 feet of trees and still attract martins. Height of the housing can be anywhere from 10-20 feet. Keep tall bushes, shrubs and vines away from the pole. Do not attach wires to a martin house, especially if they lead to trees, buildings, or to the ground. If your yard has too many trees near the martin housing, relocate the housing to a more open area, mount the housing higher, or prune (or remove) trees to create a more open site. If you have a wooded lot, but live near a body of water, boat docks make ideal locations for mounting a martin house or gourd rack.
