Earthquake is a natural phenomenon that cannot be ignored in Turkey as in the world. Since Turkey is located in the earthquake zone, research on these issues has increased in recent years in Turkey. In this study, the effects of the earthquake on the reinforced concrete and masonry/mixed buildings in the central neighborhoods of Bilecik province were examined by the Street Survey Method. In this context, a total of 1391 buildings including 1021 reinforced concrete and 370 masonry/mixed buildings on the central districts of Bilecik were examined. The average building earthquake scores for the reinforced concrete and masonry/mixed buildings of each neighborhood were calculated. In terms of reinforced concrete buildings, Bahçelievler, Cumhuriyet, Gazipaşa, Ismetpaşa and Istiklal neighborhoods were found to be at Low Risk in terms of Building Earthquake Safety, while Beşiktaş, Ertuğrulgazi and Hürriyet neighborhoods were found to be Safe in terms of Building Earthquake Safety. All masonry/mixed buildings were found to be Safe in terms of Building Earthquake Safety.
