Hiring Construction Work Permit Holders in Singapore: Do You Need CRS Registration, a Builder's Licence, or Both?
To apply for or renew Work Permits for construction workers in Singapore, your company must be registered in the Building and Construction Authority's (BCA) Contractors Registration System (CRS). A builder's licence is a separate requirement. Holding one, even a General Builder Class 2 (GB2) licence, does not by itself let you hire foreign construction workers.
The two are easy to confuse because BCA runs both, and both are applied for on the same portal. This guide explains what each one does, who needs which, and the other early requirements that catch new construction employers out, such as the construction Work Permit quota.
This guide is for companies in Singapore that hire, or plan to hire, construction Work Permit or S Pass holders.
CRS registration: what lets you hire construction workers
Since 1 June 2025, every firm that wants to hire construction S Pass or Work Permit holders must first register with CRS. This applies whatever the worker's nationality, Malaysians included, and to firms working only on private projects.
The Ministry of Manpower (MOM) states it plainly on its construction sector page: to apply for or renew S Passes and Work Permits for construction workers, your company must be registered in CRS with BCA.
A few things to know about CRS:
There are about 50 workheads, grouped into five registration groups: Construction Workhead (CW), Construction-Related Workhead (CR), Mechanical and Electrical Workhead (ME), Trade Heads (TR) and Regulatory Workheads (RW). You register in the workhead that matches the work your firm actually does. An electrical contractor registered under an ME workhead is not at a disadvantage for hiring compared with a CW firm.
Each workhead has its own Specific Registration Requirements (SRR), covering financial standing, track record, personnel and, for some, certifications. Since 1 June 2025, every firm needs at least S$50,000 in paid-up capital when it applies for or renews CRS registration. Track record requirements depend on the workhead and grade: for example, the entry grade for General Building (CW01, grade C3) asks for a S$300,000 track record over the past three years. Firms still building their track record can use a probationary registration route, but must reach a S$100,000 track record by the end of it. Check the current SRR document for your workhead on BCA's CRS page before you apply.
Your financial grade (for example C3, L1 or Single Grade) sets your public-sector tendering limit. It does not set how many Work Permit holders you can hire. Your headcount is governed by MOM's quota, not your BCA grade.
Applications are made through BCA's Electronic Builders Licensing and Companies Registration Systems (eBACS) portal, with a recent BizFile extract from the Accounting and Corporate Regulatory Authority (ACRA), your latest accounts, personnel documents and track record evidence.
You can check any firm's registration status in the BCA e-Directory.
If a firm cannot meet the requirements and is deregistered, BCA says it can still operate in Singapore, but it can no longer hire new foreign construction workers or renew the work passes of its existing ones. Firms already registered before 1 June 2025 only need to meet the new entry requirements when they next renew.
Builder's licence: who actually needs one
The builder's licence comes from BCA's Builders Licensing Scheme (BLS), under the Building Control Act. It controls who may carry out certain building works, not who may hire.
You need a builder's licence if you carry out:
General building works where the plans need approval by the Commissioner of Building Control. BCA says that in general only main contractors need a General Builder licence. Subcontractors are generally not required to hold one, except for specialist works.
Specialist works in any of six categories: piling, ground support and stabilisation, site instrumentation and monitoring, structural steelwork, precast concrete work, and in-situ post-tensioning.
The licence classes:
General Builder Class 1 (GB1): projects of any value. Minimum paid-up capital S$300,000. Fee S$1,800.
General Builder Class 2 (GB2): projects of S$6 million or less. Minimum paid-up capital S$25,000. Fee S$1,200.
Specialist Builder: specialist works of any value within the licensed category. Minimum paid-up capital S$25,000. Fee S$1,500.
All licences are valid for up to three years, and BCA processes applications within 14 working days of receiving complete documents. Every licensed builder must appoint an Approved Person (AP) to manage the building works and a Technical Controller (TC) to supervise them.
BCA's own licensing page draws the line clearly: the builder's licence is for compliance with the Building Control Act, and firms that want to apply for or renew work passes for foreign construction workers must register in CRS.
CRS vs builder's licence at a glance
CRS registration | Builder's licence (GB1, GB2, Specialist) | |
|---|---|---|
What it is for | Hiring construction Work Permit and S Pass holders; public-sector tenders | Carrying out regulated building works and specialist works |
Who needs it | Every firm hiring foreign construction workers | Mainly main contractors on plan-approved works, and specialist builders |
Issued by | BCA, through eBACS | BCA, through eBACS |
Lets you hire construction Work Permit holders? | Yes. It is required | No. It is a separate requirement |
Many firms need both. A main contractor that hires its own foreign workers needs CRS registration to hire and a General Builder licence to carry out the building works. The two are also linked: BCA's registration requirements for CW firms require a General Builder Class 1 licence for grades A1 to B2, and a Class 2 licence for grades C1 to C3.

Other requirements new construction employers hit first
CRS registration opens the door. These are the next things that typically trip up a new construction employer:
Levy bond. A new business hiring migrant workers must buy a levy bond if it is a sole proprietorship, a partnership, or an incorporated company with paid-up capital under S$50,000. It is S$600 for each Higher-Skilled or Basic-Skilled worker and S$2,000 for each Unskilled worker. The monitoring period is usually 6 months for new companies, and any late levy payment extends it by 12 months.
An MOM interview. MOM may ask selected companies to attend an interview and submit documents about their business operations. Your ACRA-registered director must attend.
Quota. You can employ 5 construction Work Permit holders for every local employee earning the Local Qualifying Salary. See our quota guide.
The 10% Higher-Skilled rule. At least 10% of your construction Work Permit holders must be Higher-Skilled (R1) before you can hire or renew any Basic-Skilled (R2) workers. Our levy guide covers the four ways to reach R1.
Security bond. Every non-Malaysian Work Permit holder needs a S$5,000 security bond in place before arrival. See our security bond guide.
Not really a construction firm?
If your company is not registered in CRS and does not plan to be, it cannot hire construction-sector Work Permit holders. MOM publishes separate guidance for firms that want to move from the construction sector to the manufacturing or services sector, where different quota and source-country rules apply. Work out which sector genuinely matches your business before you apply, because the sector decides which workers you can hire and what you pay for them.
