General contractor business guide: licensing, pricing & growth

Updated 2026-05-01

General contracting is one of the most complex and potentially most lucrative businesses in the trades. The GC is the one who coordinates everything — subs, materials, schedules, clients, and permits — and takes responsibility for the whole project. Done well, it's a highly profitable business. Done wrong, it's the fastest way to lose everything you built. Here's the complete picture.

Getting your GC license

General contractor licensing is state-regulated. Most states require:

1. Documented experience — typically 4–5 years in the trade, often requiring a journeyman's card or letters from employers
2. GC exam — tests trade knowledge, building codes, and business/legal requirements. NASCLA offers a multi-state exam accepted in many states.
3. Proof of insurance — GL coverage at state-required minimums (usually $300K–$1M)
4. Surety bond — license bond required by most state boards
5. Business registration — LLC or corporation in most states
6. Application fees — $200–$1,000 depending on state

States with the most rigorous GC licensing: California (CSLB), Florida (DBPR), Arizona (ROC), Nevada (NSCB). Texas has limited state licensing for GCs but strong municipality requirements.

Insurance and bonding — non-negotiable

GCs need more coverage than most trades because you're responsible for everything on the job site — including subs' work.

How to price a GC project

The GC pricing formula:

Never bid from gut feel or square-footage rules. Get actual sub quotes for every line item before submitting a bid.

Managing subcontractors

Your reputation is only as good as your subs'. Before putting anyone on your job:

• Verify their state license is current and matches the scope of work
• Get a COI and verify it's active — call the carrier if in doubt
• Check workers' comp coverage — if an uninsured sub is injured on your job, you may be on the hook
• Get references from GCs who've used them recently
• Use a written subcontract on every job — scope of work, payment terms, insurance requirements, and indemnification language

Contracts — never start without one

Your client contract should include:

• Detailed scope of work (what's included AND what's excluded)
• Payment schedule (typically 10–20% deposit, progress payments, final payment on completion)
• Change order process — how scope changes are priced and approved in writing
• Timeline with milestones
• Lien waiver language
• Dispute resolution process

The most expensive GC disputes come from unclear scope. Clients who add work mid-project and expect it included in the original price are the primary source of GC disputes. A clear change order process eliminates most of these problems.

Growing a GC business

• Referrals drive GC growth — a satisfied client who refers you to their network is worth $50,000–$200,000+ in future projects
• Before/after photos on Instagram and Houzz build credibility for larger projects
• Google Business Profile drives local search — "general contractor [city]" is searched frequently
• Relationships with architects and designers — they recommend GCs constantly. One strong relationship with a residential architect can fill your calendar
• Specialization — kitchen/bath remodelers, ADU builders, or historic restoration specialists command higher margins than generalists
