A HK$3,000 fixed-price pre-assessment (fully credited after signing). An Authorized Person visits on site and reviews against the 8 standards item by item, helping you judge the extent of remediation, the cost direction and the next-step route — avoiding blind starts and rework.
The pre-assessment is a preliminary risk judgement and information review; it does not constitute a final statutory certification result. If you subsequently engage us to handle certification and related works, the HK$3,000 assessment fee can be deducted from the certification fee or works fee.
Whether a unit is worth turning into a BHU depends on the partitioning, each room's area, ceiling height, fire escape, ventilation, toilet, waterproofing and the position of the water/electricity meters. Quoting and starting work before examining these easily leads to rework, runaway costs, or even a unit that still can't pass certification after the works.
Some need only minor touch-ups; others need major restructuring, or it may not even be advisable to keep letting them as subdivided units.
The difference comes from area, escape routes, toilet position, waterproofing, water/electricity meters and fire safety requirements.
The HK$3,000 assessment first helps you see the risks and direction clearly before deciding the next step (the fee is deductible).
Whether the unit is suitable for remediation and formal certification, or whether you should consider another letting strategy.
Where the problems lie in area, height, fire safety, ventilation, toilet, water supply point, water meter and electricity meter.
Grouping the unit into minor, moderate, or major/high-risk.
The likely ranges for government fees, professional certification fees, works fees and water/electricity meter arrangements.
Whether to register first, complete documents first, remediate first, certify first, or hold off for now.
A WhatsApp summary or PDF is provided, handy for communicating with partners, tenants or the works party.
Actual results are subject to the site and professional judgement; the below is for preliminary decision reference only.

Conditions are broadly close to the requirements, mostly adding equipment, documents or local fixes.

Some conditions fall short, but there's still room to adjust.

Involving escape routes, structure or major restructuring — may not be worth continuing.
Which tier your unit falls into can't be guessed. A pre-assessment first makes it clearer whether further remediation is worthwhile.
A BHU involves certification, works, documents, testing, utilities, fire safety, tenants and returns. The assessment's role is to first build a picture of the total cost and the main risks.
Government applications, professional certification reports, drawings, and compiling title and identity documents.
Depending on area, ceiling height, fire safety, waterproofing, ventilation, water/electricity meters and partition adjustments.
Access coordination during remediation, works timing and the future letting strategy.
Not every unit is worth continuing; some should reduce rooms, let as a whole, or pause.
The official minimum standards cover area, height, fire safety, structure, toilet, water supply point, lighting and ventilation, and separate water/electricity meters. The assessment reviews each against the current condition to help you grasp the main risks.
On site, depending on the unit's actual condition, we review rooms, corridors, doorways, toilets, windows, utilities, fire safety and ventilation.












The photos above only illustrate assessment items; the actual scope is adjusted to the unit's on-site condition.
WhatsApp the address, room count and approximate area; a floor plan or photos are even better (but not required).
We give a preliminary view, confirm whether an on-site assessment is worthwhile, and set a time.
An Authorized Person reviews on site, followed by a written report and a 30-minute walkthrough.

If it's not worth doing, we'll tell you honestly — we won't overlook risk just to push works.
A HK$3,000 pre-assessment, fully credited after signing, giving you the preliminary judgement and route first.
Working with a team of Registered Authorized Persons, with a single point of contact across assessment, remediation and certification.
A free survey mostly focuses on a works quote; a pre-assessment focuses on the upfront decision — understanding the risk, extent of remediation, cost direction and whether it's worth continuing. Even if you don't use our services afterwards, the report is still yours to keep for reference.
No. The assessment's purpose is to help you judge whether it's worth continuing. Afterwards you can handle it yourself, use a works party you know, use our team, or hold off for now.
The assessment fee is for a professional upfront service already provided and is generally non-refundable once completed. But if the result advises against continuing, that conclusion itself has already saved you larger downstream costs; and if you continue to engage us, the fee is fully credited.
No. The assessment is a preliminary risk judgement and information review; it does not constitute final statutory certification. Formal BHU certification must be certified by a Specified Professional according to the actual conditions and submitted through the Housing Bureau's procedures.
If the unit is let, the tenant usually needs to grant access so we can review each room, the toilet, windows, utilities and shared areas. We suggest arranging access together on a single day where possible, to minimise disruption to tenants.
Yes. Provide the floor plan, photos, room count and approximate dimensions first, and we'll do a preliminary screening, then advise whether an on-site assessment is worthwhile. Cross-border owners can take part by video.

Before remediating, applying for water/electricity meters or commissioning certification, understanding the unit's risk and cost direction is usually safer than starting work blindly.
