BHU Certification for
Mortgaged Properties
The most common question from mortgaged property landlords: do I need the bank's consent before registering or certifying my subdivided unit? The answer has two parts. Grace-period registration typically does not require bank consent. Renovation works — where required — are where the mortgage deed may become relevant.
| Compliance Step | Bank Consent Required? |
|---|---|
| Grace-period registration (before 28 Feb 2027) | Generally no — document submission only, no physical changes |
| Commissioning specified professional inspection | No — assessment involves no physical changes to the property |
| Unit already meets all Schedule 1 standards | No — no renovation required |
| Minor works (e.g. fire detector installation) | Generally no — not structural alterations |
| Toilet additions, ventilation systems | Check mortgage deed — plumbing/structural works may be covered |
| Independent water/electricity meter installation | Generally no — arranged by Water Supplies Dept / power company, not owner-initiated |

Who Is the “Owner” Under the Basic Housing Units Ordinance?
Under Section 17(1)(a) of Cap. 658, a recognition application must be made by the owner of the principal flat — or by any person with the owner's written consent. The bank, as mortgagee, is not the owner for this purpose. The registered owner in the Land Registry is the person responsible for compliance.
A mortgage transfers a security interest to the bank, not legal title. The owner retains the obligation to comply with the Basic Housing Units Ordinance, make the grace-period registration, and obtain BHU certification — irrespective of any outstanding mortgage.
⚠️ Section 8(2)(c): Mortgagee-in-Possession Exposure
Section 8(2)(c) of the Ordinance extends potential liability to “any other person who is for the time being entitled to receive the rent.” This could theoretically include a mortgagee that has taken possession of the property and is collecting rent directly. This legislative exposure is one reason why banks typically prefer to support BHU compliance rather than obstruct it — their collateral and potential liability are both at stake.
Grace-Period Registration: Why Bank Consent Is Typically Not Required
Grace-period registration under the Basic Housing Units Ordinance is a document submission to the Housing Bureau. No physical alteration is made to the property. Because standard Hong Kong mortgage deeds restrict physical alterations — not administrative registrations — grace-period registration does not trigger the alteration covenant.
Key facts about grace-period registration:
- Deadline: 28 February 2027 (12 months from 1 March 2026 when the Ordinance takes effect)
- Fee: $0 during the registration period (Schedule 2 of Cap. 658)
- Effect: Registers the existing subdivided flat under the Ordinance; preserves eligibility for grace-period certification
- Physical works: None required at this stage
- Mortgage status: Does not affect eligibility or timeline
⚠️ Do Not Wait for the Bank
Some owners delay registration assuming they need to notify or obtain approval from their bank first. This is almost always unnecessary and risks missing the 28 February 2027 deadline. The penalty for non-compliance (Section 8(3)) is severe: summary conviction carries a Level 6 fine plus 2 years imprisonment; indictment carries a $300,000 fine plus 3 years imprisonment — with an additional $20,000 per continuing day in either case.
Mortgage Deed Alteration Covenants: When Bank Consent May Be Needed
Standard Hong Kong mortgage deeds typically contain a covenant requiring the mortgagor to obtain the mortgagee's prior written consent before making any “alterations, additions or demolitions” to the property. Whether this applies depends on the scope of works required for BHU compliance.
No mortgage issue arises
If the unit already meets all Schedule 1 minimum standards — floor area, ceiling height, private toilet with flush toilet + washbasin + bathtub or shower, sink and water point outside the toilet, mechanical ventilation, fire detector, independent water and electricity meters, fire compartmentation — no physical works are required and the alteration covenant is not engaged.
Check the mortgage deed before commencing
- Toilet installation or plumbing works
- Partition wall construction or modification
- Fire door installations
- Structural alterations to achieve minimum floor area or ceiling height
Not owner-initiated physical alterations
- Independent water meter application (arranged by the Water Supplies Department)
- Independent electricity meter installation (arranged by the power company)
- Smoke/fire detector mounting brackets (minor fixtures, not structural)
Practical Steps If Bank Consent Is Needed
Where renovation works are required and the mortgage deed's alteration covenant applies, the following approach is recommended:
-
Review the mortgage deed and loan agreement
Obtain the exact wording of the alteration covenant. Some deeds distinguish between structural and non-structural works; others require consent for any works above a cost threshold. A solicitor can advise on the exact scope. -
Commission a specified professional assessment first
Before approaching the bank, establish precisely what works are needed. Under Section 17(2) of Cap. 658, a specified professional (registered architect, professional engineer in construction / building services / civil / fire / structural disciplines, or professional surveyor in building surveying — Schedule 3) must conduct a physical inspection. The resulting assessment tells you the exact renovation scope required and provides a professional basis for the bank application. -
Submit a written application to the bank with the scope of works
Attach the specified professional's assessment, estimated works cost, and confirmation that the works are required for statutory compliance under the Basic Housing Units Ordinance. Banks are generally receptive when compliance is the stated reason — it protects the collateral value. -
Document all correspondence in writing
Verbal discussions with bank representatives carry no legal weight. Ensure all requests, responses, and consent are in writing. If the bank does not respond within a reasonable period, follow up in writing and note the date of follow-up. -
Consult a solicitor if consent is refused or delayed
A solicitor can advise whether the specific works fall within the covenant's scope, and can assist in negotiating with the bank. Remind the bank of the statutory deadline — delays in granting consent do not extend the 28 February 2027 grace-period registration deadline or the 28 February 2030 certification deadline.
Recommended Compliance Sequence for Mortgaged Properties
-
Confirm grace-period registration status
Check whether registration has already been completed. This can be confirmed with the Housing Bureau. If not yet registered, do so immediately — it is free and does not require bank consent. -
Commission a specified professional assessment
The assessment determines current compliance status against Schedule 1 minimum standards and identifies any renovation works required. No physical changes are made at this stage. -
Determine renovation scope (if any)
If the assessment confirms the unit already meets all Schedule 1 standards, proceed directly to certification — no bank involvement required. -
Review mortgage deed alteration provisions
If renovation works are needed, review whether those specific works fall within the alteration covenant. Not all renovation works are covered. -
Engage bank early if renovation consent is needed
Allow sufficient time for the bank's internal review. Do not commence the works until written consent is obtained where required. -
Complete grace-period registration before 28 February 2027
This step should be done regardless of where the bank consent process stands. Registration and renovation are independent steps. -
Progress to BHU certification
Complete any required renovation, then proceed to formal recognition application. The early-bird certification fee is $0 for owners who registered between March–August 2026 and apply before March 2029. Standard fee is HKD 3,000 per unit. A valid BHU certificate is effective for 60 months from the recognition date (Section 16(2)).
Frequently Asked Questions
Does a mortgaged property still need to comply with BHU certification requirements?
Yes. The Basic Housing Units Ordinance places compliance obligations on the registered owner of the principal flat — not the mortgagee. A mortgage does not transfer ownership or exempt the property from compliance. Grace-period registration must be completed by 28 February 2027, and full BHU certification must be completed before 28 February 2030, regardless of any mortgage arrangements. Non-compliance carries a fine of up to $300,000 plus 3 years imprisonment, plus $20,000 per continuing day.
Does grace-period registration for a mortgaged property require bank consent?
Generally no. Grace-period registration is a document submission to the Housing Bureau — it involves no physical alteration to the property. Standard mortgage alteration covenants govern physical works, not administrative registrations. There is also no fee during the registration period (1 March 2026 to 28 February 2027). Owners should complete this step immediately without waiting for any bank approval.
The bank refuses consent for renovation works — what are my options?
In practice, this is rare — most banks support compliance renovations because they protect collateral value. If a bank refuses or fails to respond:
- Follow up in writing and document all correspondence with dates
- Consult a solicitor about whether the specific works fall within the covenant's scope — not all renovation works are covered
- Provide the bank with the specified professional's assessment demonstrating statutory necessity
- Note that delays in bank consent do not extend the ordinance deadlines — this should be communicated to the bank
A first step is always to commission the professional assessment, which tells you whether renovation is genuinely required and, if so, exactly what works — this is essential information before any bank engagement.
If my property is repossessed, who is responsible for BHU compliance?
For so long as the registered owner retains possession, compliance responsibility rests with that owner. However, Section 8(2)(c) of Cap. 658 extends potential liability to “any other person who is for the time being entitled to receive the rent” — which could theoretically include a mortgagee that has taken possession and is collecting rent. If repossession proceedings are underway and BHU compliance is outstanding, you should seek legal advice promptly. The bank's own liability exposure under this provision is another reason banks typically cooperate with compliance efforts.
After BHU certification, can I continue renting out subdivided units on a mortgaged property?
Yes. BHU certification is precisely what authorises continued lawful rental of subdivided units — once certified, they are referred to as “basic housing units.” A valid BHU certificate is effective for 60 months from the recognition date (Section 16(2)). Renting out a certified basic housing unit does not in itself breach standard mortgage terms, as the activity is lawful and the collateral value is protected. If in doubt about your specific loan agreement, consult a solicitor.
