Growing Vehicle Sizes Clash with Outdated Parking Standards as New National Guidelines Under Revision

In recent years, vehicles have generally grown larger, with many models now approaching two meters in width. This has led to difficulties in standard triple-row parking spaces: if adjacent cars are parked even slightly off-center, doors often cannot open properly—or worse, collide upon opening, causing dents or scratches. Complaints about "parking difficulties" have surged significantly on social media platforms. From the consumer perspective, demand for greater interior space has risen, with features like built-in refrigerators, large infotainment screens, and plush seating pushing automakers to design larger vehicles. On the industry side, new energy vehicles (NEVs) tend to be larger than their internal combustion engine counterparts of the same class due to battery packaging requirements—and larger models typically yield higher profit margins. Data shows that in the first quarter of 2026, retail sales of large SUVs grew substantially, recording the highest growth rate among all vehicle segments. In stark contrast, parking infrastructure standards have remained largely unchanged for decades. From 1998 to 2015, the minimum dimensions for compact car parking spaces saw no revision for nearly 30 years—and in practice, developers often further reduce stall widths during construction. The problem is even more acute with mechanical automated parking systems: early designs struggle to accommodate today’s larger NEVs, rendering some upper-level spots unusable and turning them into so-called “zombie” spaces. To address this mismatch between oversized vehicles and undersized parking spots, China has initiated a revision of the *Code for Garage Building Design*, with a new national standard for parking facilities expected to be released next year. The draft proposes increasing minimum length and width requirements for parking spaces. However, implementing the new standard nationwide faces significant challenges, including coordinating diverse stakeholder interests and retrofitting existing parking infrastructure. Industry experts recommend measures such as zoning parking areas by vehicle size and promoting time-sharing/shared parking schemes. The issue has evolved into a structural imbalance, requiring coordinated action across multiple government departments—and a gradual shift away from the consumer perception that “bigger cars equal higher status”—to achieve mutual adaptability between vehicles and parking infrastructure.
