The house is located at 37 Chekhov Prospekt [ru] at the intersection of Chekhov Prospekt (formerly Maly Lane) and Suvorov Street (formerly Malaya Sadovaya Street). The Kostin House has the status of an object of cultural heritage of regional significance.

The building was erected in the late 19th century as a revenue house. Its owners were the Rostov merchant Yefim Yakovlevich Kostin and his wife Domna Ivanovna Kostina. They also owned an oil mill [ru] in a building next to the Kostin House. By resolution № 411 of the Rostov Oblast Administration on 9 October 1998 the house was designated an object of cultural heritage of regional significance. In the 2000s the building was restored.
