Operators of over 60% of subdivided flats apply for 3-year grace period to meet rules

Introduction

What Happened

The Hong Kong government rolled out a comprehensive regulatory regime for subdivided flats (SDUs) in late 2023, aiming to raise safety, hygiene and habitability standards in a housing segment that houses an estimated 200,000 residents. The rules require owners to secure fire‑safety certificates, improve ventilation, provide adequate sanitation facilities and meet minimum space requirements per occupant. Failure to comply can result in fines, compulsory remediation or even closure of the units.

Within weeks of the regime’s launch, a coalition of landlords and property managers representing the majority of SDU operators submitted formal applications for a three‑year extension. Secretary Ho confirmed that the applications involve more than 70,000 subdivided units, representing about one‑third of all SDUs in the city. The request is being processed by the Housing Authority, which will assess each case on its merits and verify that operators are taking genuine steps toward compliance.

Government officials say the grace‑period request reflects the practical difficulties many operators face, such as limited financial resources, the technical complexity of retrofitting older buildings, and the need to relocate tenants temporarily while upgrades are carried out. The Housing Authority has pledged to work closely with applicants to monitor progress and ensure that the extended timeline does not become a loophole for indefinite non‑compliance.

Key Details

The three‑year grace period, if approved, will extend the deadline for meeting the new standards from the original 2025 target to the end of 2028. During this time, operators must submit detailed renovation plans, obtain necessary permits, and demonstrate incremental improvements—such as installing fire‑exits, upgrading electrical wiring, and providing separate sanitation facilities for each subdivided unit.

Applicants are required to provide evidence of financial capability, including bank statements or loan agreements, to show that they can fund the required upgrades. The Housing Authority will also conduct spot inspections and may impose interim penalties if progress is deemed insufficient. Operators who fail to show measurable advancement could see their grace‑period applications rejected or shortened.

In addition to the safety upgrades, the regime mandates that each subdivided unit must have a minimum floor area of 12 square metres per occupant and a ceiling height of at least 2.4 metres. These specifications are intended to curb the extreme overcrowding that has plagued many SDUs, where multiple families often share a single, poorly ventilated room.

Background

Subdivided flats have long been a hallmark of Hong Kong’s housing market, emerging as a low‑cost solution for low‑income families, migrant workers and students. By partitioning larger apartments into smaller, self‑contained units, landlords can generate higher rental yields, while tenants gain access to affordable accommodation in a city where private housing prices are among the world’s highest.

However, the rapid proliferation of SDUs over the past two decades has led to serious concerns about fire safety, sanitation, and overall living conditions. High‑profile incidents—such as the 2019 fire in a Kowloon SDU that claimed several lives—prompted public outcry and intensified calls for stricter oversight. The 2023 regulatory regime represents the government’s most ambitious attempt to bring the sector under formal control, balancing the need for affordable housing with basic standards of habitability.

Why It Matters

The quality of subdivided flats directly affects the wellbeing of a sizable portion of Hong Kong’s population. Improved safety standards can reduce the risk of fires, electrical accidents, and the spread of infectious diseases in cramped, poorly ventilated spaces. Moreover, ensuring adequate living space and sanitation aligns with international human‑rights norms and the city’s own public‑health objectives.

From an economic perspective, the grace period could have mixed effects. On one hand, it gives operators the breathing room to secure financing, plan renovations, and avoid sudden rent hikes that could displace vulnerable tenants. On the other hand, prolonged compliance timelines may delay the overall improvement of the housing stock, potentially extending the period during which substandard conditions persist.

What Happens Next

The Housing Authority will now review each application individually, assessing the credibility of the operators’ renovation plans, financial readiness, and commitment to tenant protection. Successful applicants will receive a formal extension letter outlining specific milestones they must achieve each year. Failure to meet these milestones could trigger enforcement actions, including fines or compulsory remediation orders.

In parallel, the government is expected to roll out support measures, such as low‑interest loans, technical assistance, and a streamlined permit‑approval process, to help operators meet the upgraded standards within the extended timeframe. Tenant advocacy groups have called for safeguards to ensure that renovations do not lead to abrupt rent increases or forced evictions, urging the authorities to monitor the social impact of the transition closely.

Over the coming months, the Housing Authority will also conduct public awareness campaigns to inform both landlords and tenants about their rights and obligations under the new regime. These efforts aim to foster cooperation, reduce resistance, and ultimately achieve a safer, healthier living environment for Hong Kong’s most vulnerable residents.

Conclusion

The collective request by operators of over 60 percent of Hong Kong’s subdivided flats for a three‑year grace period underscores the magnitude of the challenges involved in upgrading a vast, informal housing sector. While the extension offers a pragmatic solution that balances regulatory ambition with economic reality, its success will hinge on rigorous oversight, transparent monitoring, and adequate support for both landlords and tenants. If managed effectively, the grace period could pave the way for a safer, more dignified housing landscape, delivering long‑term benefits to the city’s residents and reinforcing Hong Kong’s commitment to decent living standards for all.
