What kind of construction business can I start?
Construction covers many kinds of business. Choose one you have the skills and equipment for:
- General building: new buildings, extensions and renovations
- Civil works: roads, paving, stormwater and earthworks
- Specialist trades: plumbing, electrical, roofing, painting, tiling, waterproofing
- Maintenance: ongoing repairs for property managers, schools and offices
- Subcontracting: supplying labour or a trade to a bigger main contractor
Many successful contractors start in one trade or as subcontractors before taking on whole projects.

How much does it cost to start a construction company?
The cost depends on your trade and whether you hire equipment or own it. The biggest need is usually working capital, because you buy materials and pay workers before you get paid.
| Cost item | Notes |
|---|---|
| Company registration and compliance | CIPC, cidb, NHBRC and COIDA paperwork |
| Tools and equipment | Start with hand and power tools; hire heavy plant per project |
| Transport | Bakkie or truck for workers, tools and materials |
| Safety gear | Hard hats, boots, reflective vests, harnesses, first-aid kit |
| Insurance | Contractor's all risks and public liability insurance |
| Working capital | Wages and materials until the first payment certificate is paid |
Do I need CIDB registration?
You need cidb registration to be awarded public-sector construction work above the small-value limit. Private clients and main contractors often ask for it too. New contractors start at Grade 1 in their class of work, and upgrade as their finances and completed projects grow. See CIDB registration.
Do I need to register with the NHBRC?
Yes, if you build new homes. Under the Housing Consumers Protection Measures Act, home builders must be registered with the National Home Builders Registration Council (NHBRC), and new homes must be enrolled with the NHBRC before construction starts. This protects buyers against major structural defects. Renovation-only and commercial contractors are generally not home builders, but check if your work includes building new houses.
What health and safety rules apply?
Construction is a high-risk industry. The Occupational Health and Safety Act and its Construction Regulations require employers to manage site risks, which includes:
- A health and safety plan and file for the project, which clients often ask for
- Appointing competent people for safety, scaffolding, excavations and other risky work
- Supplying protective equipment and training workers
- Reporting incidents
Larger projects need more. A construction work permit is required for bigger, higher-risk projects. Get advice from a safety professional when you take on bigger projects.
What tax and labour requirements apply?
- Register for income tax, and for VAT once taxable turnover exceeds R2.3 million in 12 months (from 1 April 2026)
- Register for PAYE, UIF and SDL as an employer, as they apply
- Register with the Compensation Fund under COIDA; construction has a higher risk rating. See COIDA.
- Pay at least the national minimum wage (R30.23 per hour from 1 March 2026), or more where a bargaining council for your trade or region sets higher rates
- Electricians and plumbers need their own trade competency registrations to sign off work
How do I price construction work?
Price from a bill of quantities or a detailed take-off of materials, then add labour, plant hire, transport, safety, insurance, overheads and margin. Include a contingency for price increases and unforeseen work, and agree payment stages in writing. See how to price your services.
How do I find construction work?
| Customer type | How to reach them |
|---|---|
| Homeowners | Referrals, Google Business Profile, Facebook, photos of finished work |
| Property managers and schools | Company profile, maintenance contracts, quick response times |
| Main contractors | Introduce yourself as a subcontractor for your trade |
| Developers | Track record, references and capacity |
| Government | CSD registration, cidb grade and tenders |
How do I get government construction tenders?
Register on CSD, keep your tax status compliant, register with the cidb in the right class, and prepare your B-BBEE affidavit, COIDA letter and company profile. Watch the eTenders portal and municipal procurement pages, attend compulsory site meetings, and bid only within your grade. See how to get government tenders.
What are the common mistakes?
- Taking a job larger than your cash flow can carry
- Under-pricing to win, then running out of money before completion
- Starting without a written contract and payment schedule
- Ignoring safety files and COIDA until a client asks
- Not keeping completion certificates, which you need to upgrade your cidb grade
