As a general contractor, you’re responsible for everything that happens on your job site — even the mistakes of your subcontractors. That’s why having a written contract and requiring liability insurance isn’t just a formality — it’s essential protection.

📝 Why Use a Subcontractor Contract?
- ✅ Defines the Scope of Work
Avoid miscommunication and make sure everyone knows their responsibilities. - ✅ Protects You Legally
Contracts provide a legal foundation if things go wrong — delays, poor workmanship, or missed deadlines. - ✅ Clarifies Payment Terms
Eliminate confusion with clear terms on compensation, timelines, and performance conditions. - ✅ Sets Quality & Safety Standards
Ensure every subcontractor meets your expectations and local code requirements. - ✅ Transfers Risk
With proper clauses (like indemnification), you reduce your liability exposure.
🛡️ Why Require Subcontractor Liability Insurance?
- ✅ Protects You from Costly Lawsuits
Covers injuries or property damage caused by your subcontractor’s work. - ✅ Limits Your Financial Exposure
Avoid out-of-pocket expenses for claims that aren’t your fault. - ✅ Meets Legal & Project Requirements
Most commercial and municipal projects require subs to carry valid coverage. - ✅ Makes You a Safer Bet
Show clients and insurers you’re serious about risk management — and potentially lower your premiums. - ✅ Eases Claims & Disputes
Insurance provides a reliable avenue for compensation if something goes wrong.
Here are four real-world claims scenarios where having a contract between a general contractor and a subcontractor makes a major difference in resolving liability and protecting the GC:
🏠 Scenario 1: Plumbing Subcontractor Causes Water Damage
The Situation:
A general contractor (GC) is overseeing the construction of a new custom home. The plumbing subcontractor improperly installs a fitting behind a wall, which later bursts and floods the newly installed hardwood floors, cabinets, and insulation. Total damage: $45,000.
With a Contract in Place:
- The subcontractor had signed a contract with an indemnification clause and provided proof of general liability insurance.
- The subcontractor’s insurer covers the damages, and the GC avoids out-of-pocket repair costs.
- The contract clearly defined the subcontractor’s responsibility for completed work, preventing legal disputes.
Without a Contract:
- The homeowner holds the GC responsible as the main builder.
- Without a written agreement or proof of insurance, the GC has no recourse and must either pay for the damages or file a claim under their own builder’s risk or general liability policy — risking higher premiums.
🧱 Scenario 2: Framing Subcontractor’s Worker Injured On-Site
The Situation:
During framing of a new home, a worker employed by a subcontracted framing crew falls from the second floor and suffers serious injuries. The worker sues the GC for unsafe site conditions and lack of fall protection.
With a Contract in Place:
- The subcontractor’s contract required them to follow OSHA standards and carry both workers’ comp and general liability insurance.
- The GC tenders the claim to the subcontractor’s insurer under the indemnification provision.
- Legal defense and damages are handled by the subcontractor’s policy, not the GC’s.
Without a Contract:
- The GC could be found liable as the site supervisor and general employer.
- Without a contract or insurance requirements in writing, the GC must handle the defense and damages, potentially costing tens of thousands and putting future projects at risk.
🔌 Scenario 3: Electrical Subcontractor Sparks Fire
The Situation:
A new home is nearly complete. During final walkthroughs, a homeowner notices flickering lights. An investigation reveals faulty wiring by the electrical subcontractor, which later causes an electrical fire. The fire damages the attic and part of the second floor — totaling $80,000 in repairs.
With a Contract in Place:
- The subcontractor’s agreement includes a clause requiring compliance with the National Electrical Code and mandates liability insurance coverage.
- The subcontractor’s insurer handles the claim, and the GC avoids delays, legal action, and financial loss.
- The indemnification clause protects the GC from any liability tied to the subcontractor’s negligent work.
Without a Contract:
- The GC becomes the primary party responsible in the eyes of the homeowner and their insurer.
- Without documented insurance requirements or indemnification, the GC is left to cover the costs or engage in costly legal proceedings to recover damages.
🏚️ Scenario 4: Roofing Subcontractor Causes Injury to Neighboring Property
The Situation:
While installing shingles on a two-story home, the roofing subcontractor fails to properly secure their equipment. A bundle of shingles slides off the roof and crashes through the windshield of a parked car on the adjacent property. The homeowner’s neighbor demands full compensation for the $4,500 in damage and files a claim for emotional distress.
With a Contract in Place:
- The subcontractor’s contract requires proper site safety protocols and lists the GC as an additional insured on their liability policy.
- The subcontractor’s insurer handles the property damage and any third-party claims.
- The GC maintains a positive relationship with both the homeowner and neighbor while avoiding direct financial exposure.
Without a Contract:
- The GC could be held liable for jobsite safety and face direct claims.
- If the subcontractor lacks coverage or refuses responsibility, the GC’s insurance may need to respond, affecting their loss history and premiums.
🧱 Bottom Line:
Don’t leave your business exposed.
Protect yourself with the right contracts and insurance requirements for every subcontractor on your site.
