BHU Certification Validity:
60 Months & HKD 2,400 Renewal
A BHU certification is not a permanent status — it expires after 60 months and must be renewed. This guide explains exactly how the 60-month clock works, what the HKD 2,400 renewal fee covers, and when landlords should start planning ahead to avoid a certification gap.
- Validity: 60 months from the recognition date (Cap. 658 s. 16(2))
- Renewal fee: HKD 2,400 per BHU (Cap. 658 Schedule 2)
- A new on-site inspection by a specified professional is required for renewal

The 60-Month Clock: When Does It Start?
Under the Basic Housing Units Ordinance (Cap. 658), section 16(2) states that a recognition is valid for the 60-month period beginning on the recognition date. The recognition date is the date on which the Housing Bureau Secretary grants the recognition — not the date you submit your application, and not the date of the specified professional's inspection.
- Start from the recognition date on your certificate
- 60 months = 5 calendar years
- Application and recognition dates may differ by weeks to months
- Record your expiry date as soon as you receive your certificate
- Recognition date: 1 August 2026
- Expiry date: 31 July 2031
- Start preparing by: January 2031
- New 60-month cycle begins on renewal
⚠️ "5 Years" vs "60 Months"
The Ordinance uses "60 months" — not "5 years." In most cases the practical effect is the same, but the specific month count controls where leap years or unequal month lengths would otherwise cause ambiguity. Always count 60 calendar months from the recognition date shown on your certificate.
What Happens If You Don't Renew
When a certification lapses without renewal, the unit loses its legal BHU status and reverts to an uncertified subdivided unit. Under Cap. 658 section 8 — which took effect on 1 March 2027 — renting out an uncertified subdivided unit is a criminal offence:
⚠️ Criminal risk of renting out a lapsed BHU
| Summary conviction | Level 6 fine + 2 years' imprisonment, plus HKD 20,000 per day |
| Conviction on indictment | Fine of HKD 300,000 + 3 years' imprisonment, plus HKD 20,000 per day |
Renewal Requirements: What You Need
The Housing Bureau requires — applying the same standards as initial certification under Cap. 658 s. 17:
- Application in the prescribed form to the Housing Bureau
- Prescribed fee: HKD 2,400 per BHU
- Report by a specified professional confirming the unit still meets minimum living standards
Under s. 17(2), the report is only valid if it is based on an on-site inspection conducted or arranged by the specified professional. The Housing Bureau requires that a specified professional — a registered architect (Cap. 408), a registered professional engineer in one of five disciplines (Cap. 409), or a registered professional surveyor in the building surveying division (Cap. 417) — physically inspects the unit. Document-only reviews do not qualify.
When to Start Preparing for Renewal
Because a lapsed certification creates immediate criminal exposure, landlords should leave ample lead time. The recommended preparation timeline:
⚠️ Allow Extra Time If the Unit May Have Deteriorated
If the inspection reveals compliance issues — worn fire detection equipment, a failing ventilation system, or plumbing problems — rectification works must be completed and re-inspected before renewal can be granted. Landlords who suspect any deterioration should commission a preliminary check a full year before expiry to avoid a compliance gap.
Initial Certification Fee vs Renewal Fee
The initial certification fee structure differs from the renewal fee. Renewal is a flat rate regardless of when the original grace-period registration was made:
| Application Type | Fee | Notes |
|---|---|---|
| Initial certification (early bird — registered Mar–Aug 2026) | HKD 0 | Free if certification submitted before March 2029 |
| Initial certification (standard rate) | HKD 3,000 | Applies where no early-bird discount is available |
| Renewal | HKD 2,400 | Flat rate per BHU per renewal cycle |
These are the Housing Bureau's prescribed fees only and exclude the specified professional's inspection and report fee, which is set by the market.
Frequently Asked Questions
How long is a BHU certification valid in Hong Kong?
Under the Basic Housing Units Ordinance (Cap. 658) section 16(2), a BHU recognition is valid for 60 months from the date of recognition — approximately five years.
When does the 60-month BHU certification validity period start?
The 60-month clock starts on the recognition date — the date on which the Housing Bureau Secretary grants recognition, as shown on the recognition certificate. It does not start from the application date or the specified professional's inspection date. Check your certificate for the exact date.
What is the BHU certification renewal fee in Hong Kong?
Under Cap. 658 Schedule 2, the Housing Bureau charges HKD 2,400 per BHU for each renewal. This flat rate is not affected by early-bird promotions or grace-period registration timing. It does not include the specified professional's inspection and report fee.
How far in advance should I apply for BHU certification renewal?
Start preparing at least six months before the expiry date. This allows time for a specified professional to conduct an on-site inspection, for any rectification works to be completed, and for the Housing Bureau to process the application. If the unit may have deteriorated, start a preliminary check one year before expiry.
What happens if a BHU certification expires without renewal?
Once the recognition lapses, the unit loses its BHU legal status and reverts to an uncertified subdivided unit. Under Cap. 658 s. 8 (in effect since 1 March 2027), renting out an uncertified subdivided unit is a criminal offence. On conviction on indictment: a fine of HKD 300,000, up to 3 years' imprisonment, plus a continuing fine of HKD 20,000 per day.
