Detroit's oldest neighborhoods are built tight — narrow lots, short front yards, porches close enough to the sidewalk to say good morning from. RAFI HOME CARE works at that scale, mowing and trimming the small yards, edging the walks, clearing leaves once September starts letting them go along the streets near Hamtramck. Little properties reward attention more than big ones do, because every square foot of them is visible from the porch swing. By late fall the beds are cut back, the walk is swept, and the house plainly looks after. Yard care sized to the block it sits on.
