As you can see it depends on the actual variety. If the tree has a ten foot spread you should place it 5 feet or more from the house. If the spread is 20 ft, it should be 10ft or more from the house. As a horticulturalist and designer I often have had to talk people into keeping tree's a healthy distance from the house. It's a shame how many times you see a 20 ft tree 3 ft from the house.
