Downey splits exactly evenly between owners and renters, and we work both sides of that line.
Downey is an unusually even city: 50 percent of occupied housing is owner occupied and 50 percent is rented. Almost nowhere lands that squarely on the line, and it means the work here alternates between a homeowner who wants their back deck to last another twenty years and an owner who needs a shared walkway safe, compliant and back in service quickly.
The city is surrounded by South Gate and Bell Gardens to the west and northwest, Pico Rivera to the northeast, Santa Fe Springs and Norwalk to the east, and Paramount and Bellflower to the south, which is the classic Gateway Cities pattern of tight parcels and mixed building stock.
