Not knowing where it is nor if it blooms, nor how old it is, I would say the leaves look like an ornamental crabapple. The tree has been tightly pruned for 10 years, at least. I see two shapes of leaves. One is the classic ovoid of an apple, the other is tri-lobed: the yellowish one right of center with another in the lower left. These lobed leaves look like what an immature apple produces. It could be yellowed due to excess watering. Apples are generally drought tolerant once established. There are some inconsistiencies with my theory of it being a crab, however. Crabs I am familiar with tend to have more exfoliation of the bark and the leaves are thinner. The brown spots are not inconsistent with several fungi, to which fruit trees are prone. Just my guess, though.
