5.3 Commercial General Liability (CGL) & Property Insurance

Commercial General Liability (CGL) & Property Insurance

Quick Summary: Commercial General Liability (CGL) insurance protects construction businesses against third-party bodily injury and property damage claims. While CGL is optional for sole proprietors and corporations, LLC contractors must maintain CGL coverage ($1M to $5M limits) under B&P Code § 7071.19. Contractors must understand the difference between Occurrence and Claims-Made coverage forms, navigate faulty workmanship exclusions, secure Additional Insured endorsements (CG 20 10 / CG 20 37), and carry specialized property floaters like Builder's Risk and Inland Marine Equipment Floaters.

CGL Policy Structure & Statutory Mandates for LLCs (B&P Code § 7071.19)

Commercial General Liability (CGL) policies are written on standard forms developed by the Insurance Services Office (ISO) (e.g., Form CG 00 01). A standard CGL policy provides three core coverages:

• Coverage A: Bodily Injury and Property Damage Liability.
• Coverage B: Personal and Advertising Injury Liability.
• Coverage C: Medical Payments (guest medical expenses regardless of fault).

Statutory CGL Mandates for Limited Liability Companies (LLCs)

While California law does not mandate general liability insurance for sole proprietorships or corporations, B&P Code § 7071.19 establishes strict mandatory CGL requirements for contractors licensed as LLCs:

Proof of CGL coverage for LLCs must be submitted directly to CSLB. Lapsing CGL insurance results in automatic license suspension under B&P Code § 7071.19(c).

Occurrence vs. Claims-Made Policies & California's 10-Year Defect Repose (Civil Code § 941)

Choosing the correct policy trigger format is critical in construction risk management due to long-term latent defect exposure under California Civil Code § 941 (Senate Bill 800), which allows property owners to file construction defect lawsuits up to 10 years after substantial completion.

Occurrence Form vs. Claims-Made Form

OCCURRENCE FORM:   [ Damage Occurs in 2024 ]  ────────────────► [ Claim Filed in 2032 ]  ► COVERED by 2024 Policy!
CLAIMS-MADE FORM:  [ Damage Occurs in 2024 ]  ───(Policy Lapsed)──► [ Claim Filed in 2032 ]  ► DENIED (No ERP/Tail)! 

Because latent defect claims (e.g., window flashing leaks or foundation settlement) often manifest 5 to 9 years post-construction, California general contractors overwhelmingly utilize Occurrence CGL policies.

Core CGL Exclusions: 'Your Work', Subcontractor Exceptions & Consequential Damage

A fundamental doctrine of insurance law is that CGL policies are not performance bonds or warranties. CGL policies are designed to cover fortuitous damage to other property, not the replacement of the contractor's own defective work.

Key Exclusions in Standard CGL Forms

1. Exclusion j (Damage to Property): Excludes coverage for property damage to the specific part of real property on which the contractor is actively working.
2. Exclusion l ('Damage to Your Work'): Excludes coverage for property damage to "your work" arising out of it or any part of it, after operations are completed.

The Subcontractor Exception & CG 22 94 Endorsement

Historically, Exclusion l contained a critical exception: "This exclusion does not apply if the damaged work or the work out of which the damage arises was performed on your behalf by a subcontractor."

[!CAUTION] Insurers frequently attach endorsement CG 22 94 (Exclusion - Damage to Work Performed by Subcontractors on Your Behalf) to residential contractor policies. Attaching CG 22 94 eliminates the subcontractor exception, leaving the general contractor completely uninsured if a subcontractor's defect causes destruction of the project!

Additional Insured Endorsements (CG 20 10 vs. CG 20 37) & Waivers of Subrogation

Project owners, developers, and public agencies routinely require general contractors to name them as Additional Insureds on the contractor's CGL policy.

Ongoing vs. Completed Operations Endorsements

• CG 20 10 (Additional Insured — Owners, Lessees or Contractors): Provides coverage to the additional insured only for liability arising out of ongoing operations actively being performed by the named contractor. Coverage terminates when project construction ends.
• CG 20 37 (Additional Insured — Completed Operations): Extends additional insured protection for liability arising out of completed operations (construction defect suits occurring post-completion).

[!IMPORTANT] Project owner contracts typically require BOTH CG 20 10 and CG 20 37 endorsements, combined with Primary and Non-Contributory endorsement wording and a Waiver of Subrogation (CG 24 04).

Builder's Risk Insurance & Installation Floaters

While CGL covers third-party liability, Builder's Risk Insurance (also known as Course of Construction coverage) is specialized property insurance protecting the structure itself while under construction.

Scope of Coverage

• Covered Property: The physical building structure, foundation, temporary structures (scaffolding, jobsite trailers), and building materials staged on-site or in transit.
• Covered Perils: Written on an "All-Risk" (Special Form) basis, covering fire, windstorm, theft, vandalism, and lightning (excluding flood and earthquake unless endorsed).
• Valuation Basis: Paid on a Replacement Cost basis as construction progresses.

Contractors Equipment Floaters (Inland Marine) & Commercial Auto / Umbrella Coverage

Contractors rely on specialized marine floaters and excess liability layers to protect physical capital and extend policy limits:

1. Contractors Equipment Floater (Inland Marine)

Standard CGL policies explicitly exclude property owned, rented, or leased by the contractor. An Equipment Floater covers heavy mobile machinery (excavators, backhoes, bulldozers, generators) against collision, overturn, theft, and jobsite damage anywhere in transit or on location.

2. Commercial Auto Policy (CA 00 01)

Required for all business-owned trucks, vans, and heavy hauling vehicles. Provides Auto Liability (Symbol 1 - Any Auto) and Physical Damage coverage (Comprehensive and Collision).

3. Commercial Umbrella / Excess Liability Policy

Provides additional policy limits (e.g., $5,000,000 or $10,000,000) over underlying CGL, Commercial Auto, and Employer's Liability policies to protect against catastrophic bodily injury or mass construction defect judgments.

Jobsite Case Example: Completed Operations & Additional Insured Coverage Dispute

Scenario

Pacific Crest Builders (General Contractor) builds a 12-unit residential condominium complex in San Jose. The owner requires Pacific Crest to provide CGL coverage with Additional Insured endorsements. Pacific Crest hires Framing Subcontractor, Blue Sky Framing. Blue Sky secures a CGL policy and provides an additional insured endorsement naming Pacific Crest Builders using Form CG 20 10 (ongoing operations only).

Three years after the condominium complex is completed and sold, severe winter storms cause roof trusses to sag and shear walls to crack due to improper framing connections installed by Blue Sky. The Homeowners Association (HOA) files a $600,000 construction defect lawsuit against Pacific Crest Builders.

Insurance Coverage & Endorsement Dispute Analysis

1. Additional Insured Claim Against Subcontractor's Insurer:

   • Pacific Crest tenders the defense of the HOA lawsuit to Blue Sky Framing's CGL insurer, demanding coverage as an Additional Insured.
   • Result: Blue Sky's insurer denies defense coverage to Pacific Crest. Why? Form CG 20 10 only covers liability arising out of ongoing operations. Because the framing work was completed 3 years prior to the lawsuit, CG 20 10 does not apply.
   • Lesson: Pacific Crest should have mandated that Blue Sky supply Form CG 20 37 (Completed Operations) in addition to CG 20 10.

2. General Contractor's CGL Response:

   • Pacific Crest tenders the claim to its own CGL carrier under its Occurrence policy written during the construction year.
   • Pacific Crest's carrier accepts the defense under Coverage A because the property damage manifested within California's 10-year statute of repose (Civil Code § 941). The carrier satisfies the $600,000 settlement and pursues direct subrogation against Blue Sky Framing.
