This study examines the dynamic adaptability of Dashilar’s hutong system and its role in maintaining street vitality and functional mix in Beijing’s old city. Defined as small-scale incremental adjustments without large reconstruction, dynamic adaptability is evaluated through four dimensions: network connectivity, human-scale proportion, functional mix, and street-edge interaction. The results indicate that Dashilar’s well-connected network and human-scale streets support walkability and small-scale commerce, while historical comparison reveals how the area has continuously adapted to socio-economic changes, maintaining long-term street vitality through such adaptive spatial processes.
