Zayo Subcontractor Insurance

Yes. Zayo Group requires all subcontractors to carry their own GL and workers' comp and name Zayo Group as additional insured. Zayo Group's MSA (Master Subcontractor Agreement) specifies minimum limits and endorsement requirements before any crew mobilizes.

Zayo Group's base requirements for all contractors: General Liability $1M each occurrence / $2M general aggregate / $2M products-completed operations aggregate; Commercial Auto $1M CSL; Workers' Compensation at statutory limits.

Construction & Turnkey contractors additionally require: Umbrella/Excess $5M/$5M and Employers' Liability $1M each accident / $1M disease each employee / $1M disease policy limit.

Agreement-specific coverages that may also be required depending on your work type: Professional Liability / E&O ($1M/$1M for A&E, structural, inspection, and elevated work; $2M/$2M for environmental services); Contractors Pollution Liability and Environmental Liability ($2M/$2M each, for remediation agreements); UAV / Drone Liability ($5M/$5M for UAS/drone service agreements). Employers' Liability limits also vary — $1M/$1M/$1M for Turnkey/Construction, vs $100K/$100K/$500K for all other agreement types.

COIs and policy documents must be submitted through Zayo Group's vendor portal Avetta. Certificate holder: Zayo Group c/o Avetta, PO Box 51387, Irvine, CA 92619. Zayo Group's own guidance: "Ensure you know the agreement(s) you are qualifying for as different requirements apply. Contact your sponsor to clarify any uncertainty."

Zayo Group subcontracts fiber installation and splicing, small cell node installation and maintenance, conduit installation, aerial fiber lashing, underground fiber boring, tower structural work, and last-mile fiber-to-the-node deployments for their nationwide network.

Zayo Group has very specific endorsement requirements. On your General Liability policy you'll need: Additional Insured for ongoing operations (CG 20 10 04 13 for network/fiber vendors, or CG 20 26 04 13 for tower vendors), Additional Insured for completed operations (CG 20 37 04 13), waiver of subrogation, primary & non-contributory, per-project general aggregate (for Turnkey/Construction), and 30-day notice of cancellation.

On your Auto policy: hired & non-owned auto coverage, additional insured, waiver of subrogation, primary & non-contributory, and 30-day notice. On Workers' Comp: waiver of subrogation. On Umbrella/Excess: GL, Auto, and Employers Liability must be listed as underlying. Your Umbrella must either follow form to the CGL, Auto, and Employers Liability — or you must provide separate copies of the Additional Insured, Waiver of Subrogation, and Primary & Non-Contributory endorsements specific to Zayo Group on the Umbrella policy.

Endorsement Language: Every endorsement must either include the exact named language "Zayo Group USA, Inc, and its parent, joint ventures, subsidiaries, and affiliates" listed in the schedule or form — or use blanket wording such as "as required by written contract/agreement." Both are acceptable; specific is fine, blanket is fine.

Policy Number Requirement: All endorsement forms must have a policy number listed that matches the policy shown on your COI. A schedule of forms with a policy number is also acceptable — as long as the required endorsement forms are listed on that schedule. Missing or mismatched policy numbers are one of the most common reasons Zayo Group COIs get flagged in Avetta.

Zayo Group maintains a list of non-compliant policy exclusions that will result in automatic rejection. Red (Non-Compliant) exclusions include: work height exclusions (if you're qualified for Construction, Turnkey, or TIA agreements), cross-suits exclusions for additional or any insureds, Action Over exclusions, any exclusion that removes coverage for Completed Operations, non-accumulation of limits endorsements, and Prior Work amendments that remove insured contract coverage.

Amber (Restricted Use) exclusions — flagged but may be conditionally acceptable — include: XCU exclusions (explosion, collapse, underground), work on bridges or highways, wildfire/welding exclusions, residential or condominium construction exclusions, Care/Custody/Control exclusions on real property for tower vendors, and cranes & boom trucks. We know which carriers have clean policies that meet Zayo Group's standards.

Zayo Group subcontractor insurance is not a standard policy you can quote online and bind in an hour. Because of the specialized work types (fiber, small cell, tower), the elevated limits required ($5M umbrella for Construction/Turnkey), and the strict endorsement requirements Zayo Group imposes, carriers underwrite each submission carefully. Plan on 1–2 weeks from the time you submit your information to the time your policy is bound and your COI is ready to upload into Avetta.

The earlier you start the process, the better — especially if you have a mobilization date coming up. We'll submit to underwriters immediately, follow up to keep things moving, and make sure the COI is issued with the correct Zayo Group additional insured language, endorsement form numbers, and policy documentation so it passes Avetta review without deficiency notes on the first submission.

Yes. Zayo Group requires workers' comp at statutory limits regardless of crew size. Construction and Turnkey subcontractors also need Employers' Liability at $1M each accident / $1M disease each employee / $1M disease policy limit. Note: if you are a Construction or Turnkey contractor, you cannot use a leasing company or Professional Employer Organization (PEO) to satisfy the workers' comp requirement — Zayo Group specifically disallows this for those agreement types.
