Originally an independent municipality, it was annexed to Brno in 1919, since November 24, 1990 it has been part of the city district of Brno-jih.

The area of today's Komárov was annexed to Brno in two phases: on July 6, 1850, the territory originally belonging to Trnitá; and on April 16, 1919, on the basis of Act No.

[citation needed] Komárov has an urban character, and as a district it was marked both by the development of industry and, in communist times, by the insensitive construction of a panel housing estate and roads on its territory.

In recent years, a number of new shops have sprung up along Hněvkovského street, south of the railway line passing through Komárov.

Since the 1980s, important and highly frequented roads have passed through Černovická, Svatopetrská and Hněvkovského streets, which sometimes cause traffic jams.
