Foundations: Things That Look Like Problems, But Aren't

architectural:  primarily cosmetic problems resulting from minor separations in the walls, floors (due to separation from foundation), ceilings, paving, etc.

functional:  affecting the use of the building; examples are doors or windows that stick, leak, will not close, or will not latch, and doors which open or close on their own ("ghost" doors). Some other examples include noticeable floor slopes or wall tilts, tilted countertops, and vertical pavement offsets sufficient to cause tripping.
