The Income House of Karapet Chernov in Rostov-on-Don is one of the monuments of pre-revolutionary architecture in the city. Built in the 1890s, it was later raised to five stories according to the design of architect Yasinsky under the guidance of engineer Chorchopyan. The building is located at the intersection of Bolshaya Sadovaya Street and Voroshilovsky Avenue and is recognized as a cultural heritage monument of the region.

The facades of the house face Bolshaya Sadovaya and Voroshilovsky Avenue. Their appearance is defined by the brackets, which on the top floor connect with paired pilasters. The central part of the building is the corner semicircular section facing the intersection, with a loggia and columns above. On the first floor, the central brackets are highlighted by porticos, while on the third and fourth floors they are decorated with four-column porticos of the Ionic order. The fifth floor is adorned with long balconies with metal railings. The facades are richly decorated with stucco and plaster: on the first floor, heraldic shields; on the second, herms; as well as decorative window frames and inserts in the form of wreaths, garlands, and lion masks.

There is a legend associated with the house about a dispute between horse breeder Karapet Chernov and wool merchant Gavriil Melkonov-Yezekov. To determine who was wealthier, they decided to build two income houses opposite each other at the intersection. The winner was the one whose house was more luxurious. Initially, the buildings had three stories, but in the early 20th century, during a construction boom, both merchants raised them to five stories. The dome of Melkonov-Yezekov's house turned out to be higher, and Chernov, unable to raise his dome, installed columns on the roof. Because of this, the house earned the nickname 'the one with columns on supports.'

Before the revolution, institutions such as the St. Petersburg International Commercial Bank, the Merchant Society of Mutual Credit, the Agricultural Bank, and dentist Sabovich rented premises in the house. After the revolution, the building was nationalized, shops opened on the first floor, and other floors housed the Palace of Labor, the sports society 'Dynamo,' 'Sevkavsnabbyt,' and other organizations. In 1931, the building was transferred to a financial and economic institute, which became the Institute of National Economy in 1964.

During World War II, Chernov's house was heavily damaged, but in the late 1950s it was restored according to the design of architects Ishunin and Petrov, now without columns on the roof. Melkonov-Yezekov's house was completely destroyed and not restored. In the 1970s, a seven-story wing was added to the northern part of the building.

Today, the building houses the Rostov State Economic University and is included in the list of cultural heritage sites of regional significance.
