Overview
Crown Castle MSAs require standard insurance limits that most specialty tower contractors can meet without difficulty. Their GL requirement is $1M/$2M with no height exclusion, umbrella at $5M-$10M depending on scope, and blanket additional insured status. Small cell and fiber segments may carry separate, lower-limit requirements than traditional tower work. Crown Castle is generally considered one of the more straightforward MSAs to comply with in the industry.
The most common compliance issues contractors encounter with Crown Castle MSAs are: failing to provide blanket (rather than scheduled) additional insured endorsements, missing per-project aggregate endorsements, and not carrying adequate completed operations coverage. Crown Castle typically requires 2 years of completed operations tail coverage.
Crown Castle evaluates subcontractor insurance annually and may audit certificates mid-term. They require 30-day advance notice of cancellation and expect certificates updated within 10 days of renewal.

- •Crown Castle requires blanket additional insured — scheduled endorsements naming only Crown Castle are typically rejected.

Frequently asked questions
What are the minimum insurance requirements for Crown Castle subcontractors?
Crown Castle typically requires $1M/$2M GL (no height exclusion), statutory workers comp, $1M employers liability, $1M auto CSL, and $5M-$10M umbrella depending on scope. Blanket additional insured, primary & noncontributory, and waiver of subrogation are required on GL, WC, and auto.
Does Crown Castle allow height exclusions on GL policies?
No. Crown Castle prohibits height exclusions on GL policies for all subcontractors, regardless of scope. This is non-negotiable and consistent across all major towercos. Standard market GL policies with height exclusions at 15, 25, or 50 feet will not pass Crown Castle's compliance review.
How much umbrella coverage does Crown Castle require?
Crown Castle requires $5M umbrella for standard subcontractor scope (maintenance, L&A, small crew work) and $10M for tower erection, structural modifications, and major build projects. The umbrella must follow form with no additional exclusions beyond the underlying policies.
Does Crown Castle require inland marine coverage?
Inland marine is recommended but not always contractually required by Crown Castle. However, contractors working on Crown Castle sites should carry inland marine for their own protection, as leased equipment, rigging gear, and tools at height are significant loss exposures.
