No damper in duct work?

Just bought a new home (built in 1982) and was looking around at the HVAC ductwork in the basement to see if I could find a damper lever to adjust more airflow to the upper levels of the house. My old three story townhouse (1985) had these small damper levers in the basement that you could adjust so that the top floor would get more airflow as it was always warmer on that floor. However, I could not find any such thing on the ductwork for this new house. Am I missing it somewhere or do they not provide this feature on some duct work?

Dampers are optional. Most builders don't want to pay for dampers and air balancing.
