Overview
SBA Communications MSAs are generally the easiest to comply with among the major towercos. Their employers liability requirement is $500K (compared to $1M at Crown Castle and American Tower), their umbrella requirement is typically $5M, and they accept either scheduled or blanket additional insured endorsements.
SBA's more flexible requirements make them an attractive first MSA for newer contractors building their insurance programs. However, contractors should be aware that meeting SBA's minimums may not be sufficient for other towercos — building a program to Crown Castle or American Tower standards from the start avoids having to restructure coverage later.
SBA requires only 1 year of completed operations tail coverage, the shortest among major towercos. Their waiver of subrogation requirements are limited to GL and WC (auto waiver is not typically required).
Key points for SBA Communications compliance
- •SBA's $500K employers liability requirement is the lowest among major towercos — but many contractors carry $1M anyway to meet other MSAs.
- •SBA accepts scheduled additional insured endorsements, unlike Crown Castle and American Tower which require blanket.
- •The 1-year completed operations tail is the shortest in the industry. If you also work for Ericsson or Nokia (3-year tail), your program already exceeds SBA's requirement.
- •SBA does not typically require waiver of subrogation on commercial auto, reducing that endorsement cost.
- •Meeting only SBA minimums may leave you non-compliant with other towercos. Build your program to the highest MSA you expect to encounter.
