A new law regulating subdivided flats in Hong Kong took effect in March 2026 [2], leaving many low-income residents facing potential eviction.

The reform targets the city's acute housing shortage and soaring rents that have historically forced families into tiny units. While intended to improve living standards, the phase-out of these illegal "shoebox" flats threatens to displace the most vulnerable populations who cannot afford standard housing.

These subdivided units are common in densely populated districts such as Kowloon [1]. Many of these spaces are exceptionally small, with typical units measuring only three square metres [1]. Residents like Lisa Lau and Guan Ci now face uncertainty regarding where they will live as their current dwellings are deemed non-compliant under the new legal framework.

The government introduced the measures to address decades of pervasive inequality and the proliferation of unsafe living conditions [4]. By mandating stricter regulations for subdivided flats, the law aims to eliminate the most extreme examples of overcrowding. However, the transition has created a gap between the removal of illegal housing and the availability of affordable alternatives.

Reports from late May 2026 [3] indicate that tenants are struggling to find viable options as the law is enforced. The move to phase out these units puts pressure on the city's social housing systems, which must now accommodate a surge of displaced residents from the informal rental market.

Local advocates said that without a corresponding increase in public housing, the reform may simply shift the crisis from illegal flats to homelessness, or further overcrowding in other unregulated sectors.

Typical units measuring only three square metres.

This regulatory shift highlights the tension between urban safety standards and the reality of Hong Kong's extreme real estate market. While the law removes hazardous and undersized living conditions, it does so without providing an immediate safety net for the low-income demographic it intends to help, potentially exacerbating the city's homelessness crisis.
