to a house (or any other permanent structure) is the spread of the crown
at maturity. This is primarily to allow sufficient air circulation and to
avoid overcrowding of the branches, but it does tends to coincide somewhat
with the spread of the root system as well. This rule of thumb does not
hold true for all trees - fastigiate or columnar forms can be planted
closer, provided they do not have invasive root systems and some trees'
roots are just too aggressive to risk planting them close. Many trees'
roots, when encountering an obstacle such as a foundation, will just turn
away in another direction. FWIW, I have never seen or heard of a
foundation being damaged by a maple's roots.
