Since the Basic Housing Unit Ordinance (Cap. 658) came into force on 1 March 2026, owners of subdivided units in Hong Kong are working to a four-year timetable rather than a single form. Grace period registration closes on 28 February 2027, and certification has to follow within a 36-month grace period after that. Plenty has been written about floor area, ceiling height and fire safety. Far less has been said about the day the contractor starts work, which is the day your insurance position changes. This guide covers three phases: the works, the tenancy, and the situation nobody wants to be in, renting out a unit that was never registered.

FAQ
1. The timetable: four years, three deadlines
Date | What happens |
|---|---|
1 March 2026 | Cap. 658 takes effect; grace period registration opens |
28 February 2027 | The 12-month registration window closes. No registration means no grace period protection |
1 March 2027 | Enforcement begins. Renting out a subdivided unit with neither valid registration nor certification is a criminal offence |
1 March 2027 to 28 February 2030 | 36-month grace period: registered units may continue to be let while works and certification proceed |
28 February 2030 | Grace period ends. Every subdivided unit needs Basic Housing Unit certification |
The penalties are not nominal. Letting a subdivided unit without valid registration and certification carries, on summary conviction, a fine of up to HKD 100,000 and two years' imprisonment; on indictment, a fine of up to HKD 300,000 and three years. Both can carry a further daily fine of HKD 20,000 for a continuing offence, which passes HKD 600,000 inside a month.
The schedule to the ordinance sets eight minimum standards for the living environment: a floor area of at least 8 square metres (about 86 square feet), clear ceiling height, fire safety provisions, floor loading, an independent toilet, a water supply point and washing facilities, natural lighting and ventilation, and separate water and electricity meters. In practice almost every existing subdivided unit needs work to partitions, plumbing, wiring or fire provisions. That means a contractor on site.
2. During the works: the two certificates to see with your own eyes
The moment work starts, both your property cover and your legal exposure change. The common assumption at this stage is that the works are the contractor's problem. When something goes wrong, owners rarely walk away clean.
Ask the contractor for copies of two policies before anyone lifts a hammer. A verbal assurance is not a policy.
Policy | What it covers | What the owner should check |
|---|---|---|
Contractors' All Risks (CAR) | Section I: the works themselves, materials and completed sections. Section II: third party injury and property damage | Does the period of insurance cover the whole programme, including the maintenance period? Does the sum insured match the contract sum? Is the owner named or added as an insured? Is damage to neighbouring flats covered? |
Employees' Compensation (EC) | The contractor's own workers injured in your unit | Is the policy current? Do the insured trades and headcount match the job? Does it extend to sub-contractors and casual labour, which is where site injuries usually happen? |
Under the Employees' Compensation Ordinance (Cap. 282), primary responsibility for an injured worker rests with the employer, which is the contractor. Where the contractor has no valid EC cover, the injured employee may pursue the layer above in the chain of sub-contracting. Subdivision work is often sub-let two or three deep, and the principal contractor and the owner sit at the top of that chain. Asking to see a current EC policy is not paperwork. It is the wall between you and someone else's uninsured claim.
One more item gets missed regularly. Most subdivision work falls under the Minor Works Control System, which requires a registered contractor and, depending on the class of works, a registered inspector. A cheaper unregistered crew saves a five-figure sum on the quote and can cost far more than that on the day something goes wrong.
3. Once let: you are the occupier, not merely the owner
Once the unit is let, collecting rent is not the whole of your position.
Under the Occupiers Liability Ordinance (Cap. 314), the occupier of premises owes visitors a common duty of care: to take such care as is reasonable in the circumstances to see that the visitor is reasonably safe. Where one flat has been divided into several units, you usually retain control of the shared parts. Corridors, staircases, the meter cupboard, fire equipment, the rooftop water tank. Overloaded wiring that starts a fire, a leaking corridor that puts someone on the floor, a fire door blocked with stored goods: when any of that causes injury, the claim comes back to whoever controlled the space.
This is third party liability, and it is normally picked up by Public Liability cover or a landlord liability section. Buying it is optional. The duty is not. For how the Hong Kong courts have split responsibility between a registered owner, the person actually in charge, and the occupier, see our note on occupiers' liability.
4. Fire and householder cover: subdividing is a change of risk
Most householder policies are written for a flat in owner-occupation. Dividing that flat and letting it to several households is, in policy language, both a change of use and a material change of risk. Many policies carry an express condition requiring you to notify the insurer beforehand and obtain written agreement, failing which cover can cease to respond from the moment of the loss.
A mortgaged property carries a second layer. The fire policy the bank requires is normally written on a reinstatement basis. Turn one flat into four partitioned units with additional toilets, plumbing and wiring, and the cost of reinstatement is no longer what it was. Leaving the sum insured where it was is underinsurance, and the insurer can reduce the claim proportionally.
Situation | Policy that usually responds | Where it goes wrong |
|---|---|---|
Fire in the unit (overloaded wiring, appliances) | Fire or property policy | Subdivision and letting never notified, so the basis of cover is challenged; sum insured still reflects the old reinstatement cost, so the claim is scaled down |
Tenant's belongings destroyed | The tenant's own contents policy | A landlord policy does not usually cover tenants' property |
Someone injured in the shared parts | Public liability or landlord liability | Shared parts in a subdivided flat carry higher exposure; read the limit and the exclusions line by line |
Neighbouring flat damaged during the works | The contractor's CAR, Section II | If the owner is not on the policy, the owner has no claim under it |
A worker is injured | The contractor's EC | No cover, or no extension to sub-contractors, and the claim travels up the chain |
5. Renting unregistered: a policy problem as well as a legal one
From 1 March 2027, letting a subdivided unit with neither valid registration nor certification is a criminal offence. Most owners weigh that as a question of enforcement odds. There is a second consequence that gets discussed far less.
An insurance contract rests on accurate disclosure. How a property is actually used, whether owner-occupied, let as a whole, or divided and let to several households, is basic underwriting information. If the declared use does not match the reality, or the property is being let unlawfully, the insurer has grounds to question the basis of cover when a claim comes in. So an unregistered unit is not only a fine waiting to happen. It is the risk of having no one to pay for the fire.
A fine has a ceiling. A burnt-out floor with no cover does not.
6. A five-step checklist for landlords
Start with the deadline. Complete grace period registration before 28 February 2027. Without it, the 36-month grace period that follows does not apply to you.
Collect both contractor policies before work starts. CAR, with the period of insurance covering the full programme, a sum insured that matches the contract, and the owner's position on the policy made clear. EC, extended to sub-contractors and casual labour. Do not settle for "we're definitely covered."
Notify your own insurer in writing. State that the property will be subdivided and let, the scope of works and the expected completion date, and ask for written confirmation of how cover stands. Most owners skip this step, and it is the one most easily challenged later.
Revalue the sum insured. Reinstatement cost after subdivision is not what it was before. Adjust the fire sum insured so a claim is not scaled down for underinsurance.
Put the third party cover back. The shared parts are your exposure. The public liability limit and its exclusions should follow the number of units and the condition of the building.
When we go through policies with owners and contractors, three things come up again and again: the contractor's CAR has expired while the works are still running, the owner is nowhere on the CAR policy, and the householder policy was never told about the subdivision. None of that shows on a quotation. You only see it in the policy and the schedule.
FAQ
Q: When does Basic Housing Unit registration close, and what happens if I miss it?
A: The grace period registration window runs for twelve months from 1 March 2026 and closes on 28 February 2027. From 1 March 2027, letting a subdivided unit with neither valid registration nor certification is a criminal offence, carrying up to HKD 100,000 and two years' imprisonment on summary conviction, or up to HKD 300,000 and three years on indictment, plus a daily fine of up to HKD 20,000 for a continuing offence.
Q: Who insures the conversion works, the owner or the contractor?
A: Contractors' All Risks and Employees' Compensation are normally taken out by the contractor, but the owner should ask for copies and confirm three points: that the period of insurance covers the whole programme, that the sum insured matches the contract sum, and whether the owner is named on the policy. If a worker is injured and the contractor has no valid EC cover, the Employees' Compensation Ordinance (Cap. 282) allows the claim to travel up the sub-contracting chain, and the owner is not automatically clear of it.
Q: My flat is subdivided and let. Is my householder policy still good?
A: Ask the insurer. Most householder policies are written for owner-occupation, and subdividing then letting is both a change of use and a material change of risk, which most policies require you to notify in advance and have agreed in writing. If a loss happens and you never notified, the insurer can question the basis of cover. Notify in writing and keep the written reply.
Q: Does the fire sum insured need to change?
A: Usually yes. Fire cover is written on a reinstatement basis, and after subdivision there are more partitions, additional toilets, and new plumbing and wiring to reinstate. Leaving the old figure in place is underinsurance, and a claim can be reduced proportionally. Revalue once the works are complete.
Q: If a tenant falls in the shared corridor, is the landlord automatically liable?
A: Not automatically, but the landlord is regularly one of the defendants. The Occupiers Liability Ordinance (Cap. 314) requires the occupier to take reasonable care for visitors, and in a subdivided flat the corridor, staircase and meter cupboard normally remain under the landlord's control. That exposure is answered by public liability cover.
Next step
If you hold subdivided units and are about to register or have a contractor lined up, the useful move is not to raise a limit. It is to check three things: the dates and named insureds on the contractor's CAR and EC, whether your own property insurer has been told about the subdivision and letting, and whether the fire sum insured matches the reinstatement cost after conversion. Send us the policies, the schedules and the works contract and we will go through them with you.

Conclusion
Subdividing a flat and letting it out changes the risk, not just the paperwork. The two points that trip owners up: skipping the contractor's CAR and EC policies before work starts, and never telling your own insurer in writing once the unit is let. Either gap can cost you the claim exactly when you need it. Reviewing a subdivided unit? WhatsApp us and we will check the cover before anyone moves in.
