How Modular and Prefab Construction Impacts General Liability Insurance

Modular and prefabricated construction is reshaping the building industry. Once considered a niche approach, modular construction has gained widespread traction due to its efficiency, cost savings, and reduced environmental impact. The global modular and prefabricated construction market is projected to reach $173.44 billion by 2028, signaling a major shift in how projects are built.

While modular construction speeds up timelines and reduces on-site labor needs, it also introduces unique liability considerations. The risks associated with transporting, assembling, and integrating prefabricated units differ from those in traditional construction. For brokers working with artisan contractors in this space, understanding how general liability insurance for contractors adapts to modular and prefab projects is essential.

Key Liability Risks in Modular and Prefab Construction

The modular construction process shifts many risks from the job site to off-site manufacturing facilities, but liability doesn’t disappear — it simply takes a different form. Contractors working on modular projects face distinct exposures that need to be addressed within their general liability policies.

Property Damage From Prefab Unit Defects

Because modular components are preassembled off-site, any design or manufacturing flaws in the units themselves can result in liability claims. If a defective module is installed and later causes damage — such as structural instability or water intrusion — the contractor may be held responsible for the resulting property damage or costly repairs. These risks must be accounted for in modular construction insurance policies.

Site-Specific Hazards Vs. Factory Hazards

In traditional construction, liability risks stem primarily from on-site activities like framing, electrical work, and plumbing. In modular construction, a significant portion of the work happens off-site in controlled factory settings, shifting liability to manufacturing partners. However, once modules are transported to the job site, general contractors are responsible for installing units safely, securing them, and integrating the structure with existing components. This transition of liability requires careful consideration when structuring insurance coverage.

How General Liability Insurance Adapts to Modular Construction

Modular construction challenges traditional risk assessment models, requiring insurers to adjust policies accordingly.

Third-Party Property Damage Protection

Traditional construction sees liability primarily in the form of gradual worksite risks, but modular projects can introduce sudden, large-scale exposures. If a module is dropped, misaligned, or damages an adjacent structure during installation, contractors could face expensive property damage claims. Brokers must ensure their clients’ policies provide adequate third-party property damage protection specific to modular construction.

Completed Operations Considerations

Liability doesn’t end after modular building assembly. If defects in the prefab units or improper site integration lead to failures after project completion, contractors may still be responsible. Completed operations coverage plays a crucial role in mitigating these risks, extending liability protection beyond the construction phase.
