Baton Rouge Housing Stock
The median Baton Rouge home dates to 1975, according to the Census ACS. That makes the typical house about 51 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 41,000 households here own their home, 46.9% of the occupied total. Homes here have a median value of $224,500 and households a median income of $49,944. Those two numbers drive the labor adjustment in our estimate.
East Baton Rouge Parish had 17 hail days and 27 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 3.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. East Baton Rouge Parish also had 2 tornado days in that period.
