In Lithko Contr., LLC v. XL Ins. Am. Inc., No. 31, Sept. Term, 2023, 2024 Md. LEXIS 256, the Supreme Court of Maryland considered whether a tenant who contracted for the construction of a large warehouse facility waived its insurer’s rights to subrogation against subcontractors when it agreed to waive subrogation against the general contractor. The court ultimately decided that the unambiguous language of the subrogation waiver in the development agreement between the parties did not extend to subcontractors. The court also held that the tenant’s requirement that subcontracts include a subrogation waiver did not, in this case, impose a project-wide waiver on all parties. The court, however, found that the requirement that the subcontracts include a similar, but not identical, waiver provision rendered the subcontract’s waiver clauses ambiguous and remanded the case to the lower court to determine if the parties to the development agreement – i.e., Duke Baltimore LLC (“Duke”) and Amazon.com.dedc, LLC (“Amazon”) – intended that the waiver clause in the subcontracts covered claims against subcontractors.

This case involved roof and structural damage to a warehouse in Baltimore, Maryland that Duke owned. In March 2014, Amazon entered into a development agreement with Duke for the construction of the warehouse. Amazon also agreed to subsequently lease the warehouse from Duke. Although Amazon essentially owned and/or developed the project, the development agreement identified Duke as “Landlord” and Amazon as “Tenant.”
