Mitigating Environmental Risks in Life Science Leases

A lot of hazardous material passes through these facilities, so caution is necessary.

Life science industries span a range of uses — clinical research and trials; biologics; medical devices; pharmaceuticals; vaccines research, development, manufacturing, and distribution; plant and animal technology; and veterinary products, to name just a few. Leases for life science facilities can present unique challenges and considerations for building owners. Besides the particular demands life science uses place on electrical capacity, HVAC, floor loads, and waste removal, the activities within these facilities can pose many other risks.

Inherent in many life science facilities is the utilization, storage, and/or distribution of hazardous or toxic materials under applicable environmental laws. Of course, most common leases will contain standard indemnification clauses allocating responsibility to the tenant for losses resulting from its activities. 

When it comes to environmental issues, though, there are unique concerns for owners of life science properties. These include the ecological indemnity the principal owners provide to their lender (which typically comes from a well-funded source other than the property owner). There’s also the strict liability imposed under federal law on anyone in the chain of title for additional cleanup costs, whether or not they caused the contamination. 

Also, another lingering fact involves the owner would typically only have recourse from the tenant for a breach of the lease’s environmental restrictions.


(While the lease may include a security deposit, it is unlikely that it will be sufficient to address the incurred costs.) When the tenant is an established pharmaceutical company or medical device maker, the owner may feel comfortable with the financial stability that can support these obligations. However, many life science companies are startups, often backed by private equity or venture capital funds. These firms have more limited operating histories, capital reserves, and more uncertain future earnings.

Typically, the tenant has the most control over what material comes to the property and its handling, while the owner is more removed from day-to-day operations. Given the disconnect between the parties’ relative degree of control and potential for personal liability should environmental contamination occur, the owner of the life science project should include additional guardrails and mechanisms in the lease document to monitor operations at the property and protect against environmental exposure. Examples of steps owners may take to manage these risks include:

Upfront disclosure. Identify and limit the hazardous materials that come into the premises and the quantity of those items. Independent environmental professionals should review this materials list to confirm they are necessary and reasonable. Where the property or handled material is subject to a “right to know” law, ownership may need to provide notice to other tenants or neighbors of the specific materials in the building.

Monitoring. The owner must be able to enter and inspect the premises periodically to confirm compliance with applicable covenants and requirements.

Environmental insurance. Ownership should require the tenant to carry pollution-related legal liability insurance that covers the owner and the tenant against property damage, bodily injury, cleanup costs, and claims. The duration of this insurance should extend beyond the end of the lease. The terms and limits should be satisfactory to the owner. 

Reporting. If not already in hand, the owner or the tenant may want to perform a baseline report establishing the property’s environmental condition at the beginning of the lease term. (The owner will undoubtedly like the tenant to execute and deliver such a report to the landlord, at the tenant’s expense, if a release or contamination occurs and again, at the end of the lease term, whether or not a release has occurred.) Periodically throughout the period, the owner may want the tenant to provide (or ownership may want the right to perform) an updated report, with the responsibility for the cost of the update being a negotiable item. 

Decommissioning. At the end of the lease term, the tenant should dismantle and remove any equipment used to handle hazardous materials, remediate any contamination and restore the affected areas to a satisfactory condition.

These suggestions are in addition to the usual lease provisions requiring indemnification, compliance with laws, a notice of claims, and survival of liability. 

Other lease provisions may also warrant special attention in this context. One example is the assignment and subletting provision. Ownership may want to ensure that successors to the originally-named tenant, whether by merger or assignment, maintain adequate liquidity and net worth to meet the tenant’s obligations under the lease. Elsewhere, ownership may require periodic financial reports from the tenant to confirm that it maintains adequate liquidity and net worth to meet its lease obligations, whether or not a merger or assignment has occurred.

In light of the severe consequences, should a violation of environmental covenants occur, the owner must understand the nature of the ongoing activities by the life science tenant in advance and include provisions in the lease protecting it. Besides having these provisions crafted by qualified legal counsel, the substance and nature of the activities to be conducted by the prospective life science tenant will need to be reviewed by environmental professionals.
