- Starting a construction company in Hong Kong means registering an ordinary company, then clearing up to two extra gates. Only the company itself applies to everybody.
- Company registration is the same as for any Hong Kong business: Companies Registry plus Inland Revenue Department.
- Buildings Department registration applies only if you carry out building or street works for private developments, under section 8B(2) of the Buildings Ordinance. It lasts 3 years.
- Employees’ compensation insurance is mandatory from your first employee, with cover of not less than HK$100 million per event for employers with 200 or fewer staff.
- Employing anyone without that cover carries a maximum fine of HK$100,000 and 2 years’ imprisonment.
- A construction company isn't a special legal type: you register an ordinary Hong Kong business, then check two extra gates.
- Company registration: always, if you want a limited company.
- Contractor registration: only for building or street works on private developments, under section 8B(2) of the Buildings Ordinance.
- Employees' compensation insurance: always, from your first employee, at HK$100 million minimum cover.
Three rules decide how you start a construction company in Hong Kong, and most people research the wrong one first. Two of them catch far fewer businesses than the names suggest. The third catches every employer, from day one, and carries a HK$100 million minimum.
Contractor registration is the one everybody asks about. It’s also the narrowest: it attaches to building or street works for private developments, not to every business with “construction” in its name. Employees’ compensation insurance is the reverse. It isn’t a construction rule at all, which is exactly why it gets missed.
In this guide, you’ll learn:
- What a construction company is in Hong Kong, and what it isn’t
- Which of the three requirements apply to your specific work
- How to register the company itself
- What Buildings Department registration covers, and who genuinely needs it
- The insurance duty every Hong Kong employer carries, construction or not
What is a construction company in Hong Kong?
Hong Kong doesn’t have a separate legal entity called a construction company. You register an ordinary business, usually a private limited company, and the work you take on afterward decides which extra rules apply.
In everyday use, “construction company” means a firm that carries out building, fitting-out, repair, or related site work. The Buildings Department defines it more narrowly: only some of that work counts as building or street works for private developments. Design, project management, procurement, and many renovation jobs sit outside that definition, so two businesses with “construction” in the name can face completely different registrations.
What every construction business still shares is the company itself:
- Companies Registry incorporation
- An Inland Revenue Department Business Registration Certificate
- Employees’ compensation insurance once you hire anyone
Do you need contractor registration, or just a company?
It depends entirely on the work you do, and this table is the fastest way to find your own position.
Requirement | Does it apply to you? | Who decides |
Company registration | Always, if you want a limited company | Companies Registry and the Inland Revenue Department |
Registered contractor (RGBC or RSC) | Only if you carry out building or street works for private developments | Buildings Department, under section 8B(2) of the Buildings Ordinance. Valid 3 years |
Employees’ compensation insurance | Always, from your first employee, full-time, part-time or temporary | Statutory duty under section 40 of the Employees’ Compensation Ordinance (Cap. 282) |
The middle row is the one people get wrong, in both directions.
If you do design, project management, procurement, or trades outside building and street works, your answer differs from a main contractor’s. Assuming you need registration when you don’t wastes months. Assuming you don’t when you do is worse.
How do you register a construction company in Hong Kong?
Exactly as you would any other Hong Kong company. Nothing in the filing is construction-specific. Buildings Department registration, if you need it, is a separate application later.
Step 1: Choose the structure
Site work carries injury and liability risk, and a sole proprietorship holds that risk personally. A limited company keeps those liabilities off your personal assets, which is a stronger argument for incorporating here than in most trades. The trade-offs sit in choosing between a limited company and sole proprietorship.
Step 2: File for incorporation
You file Form NNC1 and the articles of association with the Companies Registry, usually through e-Registry. The form sets out the company name, the Hong Kong registered office, share capital, directors, shareholders, and the company secretary. Three rules to know:
- You need at least one natural-person director.
- The secretary must be a Hong Kong resident or a TCSP-licensed firm.
- A sole director cannot also be the secretary.
Step 3: Collect the Business Registration Certificate
Under the one-stop service, the Inland Revenue Department issues the Business Registration Certificate alongside the Certificate of Incorporation. For a new local company, there’s no separate IRD application to file.
Step 4: Set up the registers that must exist from day one
That includes the Significant Controllers Register, kept in Hong Kong. Miss it and you’re in breach already, even before you’ve taken a single job.
Contractor registration and insurance aren’t part of this filing. The company can exist before either is in place, but don’t start site work until the ones that apply to you are. For the full sequence, including banking, how to start a business in Hong Kong walks through each step.
Who actually needs registered contractor status?
Only contractors carrying out building or street works for private developments. If that’s your work, you must register as a registered contractor under section 8B(2) of the Buildings Ordinance. The requirement is set out in the Buildings Department’s contractor registration guides.
There are two categories:
- A Registered General Building Contractor (RGBC) covers general building works
- A Registered Specialist Contractor (RSC) covers specialist categories
Registration runs for 3 years in both cases.
Eligibility isn’t a form-filling exercise. The Department looks at four things:
- Your management structure, if you’re a body corporate
- Your personnel’s experience and qualifications
- Your access to plant and resources
- Whether the people appointed to act for you can actually do so
If your work sits outside building and street works for private developments, this may not apply to you at all. Small-scale renovation and repair often sit on a different register: Registered Minor Works Contractor (Company), or RMWC(Co), under the Building (Minor Works) Regulation.
Check which register covers your actual scope before you plan around it. Sleek doesn’t handle contractor registration, and applications go to the Buildings Department directly.
Key personnel cannot serve two registered contractors at the same time. The Buildings Department's eligibility rules cover the Authorized Signatory, Technical Director and Other Officer roles, and a person appointed for one registered contractor cannot simultaneously act for another. Borrowing a qualified technical director from a friend's company doesn't work.
What insurance are you legally required to carry?
Employees’ compensation insurance, from your first employee, with no exceptions for small teams. Section 40 of the Employees’ Compensation Ordinance (Cap. 282) is blunt about it. No employer shall employ any employee in any employment unless there is in force a policy of insurance covering injuries at work. That wording is quoted from the Labour Department’s guidance on the Ordinance.
It covers everyone you employ. Contract length doesn’t matter, nor do hours, nor whether the role is full-time, part-time or temporary. A two-person crew needs it as much as a two-hundred-person one.
The minimum cover depends on headcount:
- 200 or fewer employees: not less than HK$100 million per event
- More than 200 employees: not less than HK$200 million per event
Employ someone without that policy in force and you face a maximum fine of HK$100,000 and imprisonment for 2 years. Surcharges to the Employees Compensation Assistance Fund Board come on top.
One thing worth being clear about: This isn’t a construction rule. It’s a universal employer duty, and it catches construction businesses more often only because they hire earlier and carry more site risk. It sits alongside payroll and employer obligations generally.
The Labour Department says plainly that the statutory minimum is not the maximum liability you may bear under the law, including common law. For a trade where a single site accident can exceed any policy floor, treat HK$100 million as the legal starting point rather than an assessment of your actual exposure. Talk to an insurer about the work you genuinely do.
What else does a construction employer have to get right?
Hiring site staff brings the standard Hong Kong employer package, and none of it is construction-specific. You’ll need:
- Written employment terms
- MPF enrolment for eligible employees (the contribution side is covered in MPF obligations for your employees)
- Payroll records the Labour Department and IRD can both work from
Two things catch trade businesses in particular:
- A fluctuating crew doesn’t mean fluctuating obligations. Casual and short-term workers still count for insurance, and often for MPF.
- End-of-employment entitlements accrue quietly. Severance and long service payments are the ones people discover late.
If you’re unsure which other approvals touch your business, which licences and permits apply to your business routes by industry.
What does it cost to get started?
Three cost buckets, and only one of them is reliably knowable in advance.
1. Company setup: the predictable one
Incorporation fees, the business registration fee, and your company secretary are standard costs with published figures, broken down in what company registration costs.
2. Contractor registration: a prescribed fee
The Buildings Department sets this. Check the current amount on the Department’s fees page rather than a figure quoted in a guide, since it changes.
3. Insurance: quoted, not listed
Premiums depend on your trade, headcount, payroll, and claims history. An interior fit-out firm and a foundation contractor won’t pay the same for the same HK$100 million floor. Get quotes early: the policy has to be in force before your first employee starts, not after.
Plant, tools, and site setup are real costs too, but they’re commercial rather than regulatory. They vary too widely for a useful range, so budget them from actual quotes.

How do you win work once you’re set up?
Registration gets you permitted. It doesn’t get you paid. Those are two separate problems, and the second one takes longer to solve. Public and private work reward different things, so treat them as two tracks.
Government and public works
These run through their own approved contractor lists, held separately from your Buildings Department registration. Getting onto one is its own application, judged on track record, financial standing, and past performance rather than registered status alone. So a firm can be fully registered and still shut out of public tenders until it’s on the right list. Check the entry rules for the specific list you’re targeting before you build a plan around that pipeline.
Private work
Private jobs are won on things that sound unglamorous:
- A clean safety record
- References you can name
- Insurance certificates and registration details you can produce on request
None of that exists on day one, which is the real problem a new firm faces. Subcontracting for an established main contractor is how most build it: you earn site history, a paper trail of completed work, and a reference willing to vouch for you, all before you bid for contracts in your own name.
How Sleek helps you set up the company
Sleek handles the company side of a construction business, which is the part that looks the same whatever trade you’re in.
With Sleek, you can:
- Incorporate and register together: your Certificate of Incorporation and Business Registration Certificate handled as one process.
- Run payroll properly: MPF, employment records and the reporting that comes with a fluctuating site crew.
- Keep the books contract-ready: accounting for a construction business, including the job-level records main contractors and auditors ask to see.
- Stay ahead of filings: annual returns, business registration renewal and tax deadlines tracked so nothing lapses mid-project.
What Sleek doesn’t do is contractor registration or insurance. Those go to the Buildings Department and an insurer respectively.

FAQs about starting a construction company in Hong Kong
Yes. Hong Kong company ownership isn’t restricted by nationality or residence, so a non-resident can own and direct a construction company here. Contractor registration and the employer insurance duty apply the same way regardless of who owns the business. What changes is the practical side: you’ll need a Hong Kong registered office and, if you intend to work here yourself, the right visa.
Possibly, and it’s worth checking rather than assuming. Small-scale renovation and repair often sit under the Buildings Department’s Registered Minor Works Contractor (Company) register, not the RGBC or RSC registers for building or street works. Confirm your actual scope with the Department before you plan around the wrong category.
Main contractors and private clients commonly ask for third-party or public liability cover, and sometimes contractors’ all risks, as a contractual condition. None of those is a statutory requirement in the way employees’ compensation insurance is. Treat them as commercial terms you negotiate, and read what a contract actually obliges you to hold before you sign it.
It covers employees, so the answer turns on whether you’re one. A sole proprietor isn’t their own employee. A working director employed under a contract of employment generally is, and should be inside the policy. Check how your own position is treated with your insurer, because owners assuming they’re covered is a common and expensive gap.
No. Incorporation creates the company. It doesn’t authorise site work. You still need employees’ compensation insurance in force before anyone works, and Buildings Department registration if you carry out building or street works for private developments. Treat the Certificate of Incorporation as the first gate, not permission to start on site.

No. Registered contractor applications go to the Buildings Department, which assesses your management structure, personnel qualifications and access to plant. Sleek’s lane is the company itself: incorporation, company secretarial work, payroll and accounting. Those are separate workstreams, and you can run them in parallel.
