Mid 20th Century
The city directories and census data continue to show the evolution of the neighborhood from residential to commercial. There are fewer and fewer people listed each year. The 1939 real property survey and low income housing area survey map shows this change. The Brennan House, which is outlined in red, has a spotted background which indicates that it is a residential property. The solid black blocks are commercial buildings. The patterned buildings across the street are industrial. This map shows the last remaining historic residence on the block. Eventually, the house becomes the last historic residence in all of downtown Louisville. This is due in part to the popularity of the automobile and major roadway projects. These inventions allowed for people to move further and further away from the city center while still being able to access it easily.
