The lineage warehouse fire: Key considerations for property owners on solar, environmental risk and business resilience

When most people think of an environmental disaster, they picture leaking drums, oil spills, chemical releases, or hazardous waste sites.

They do not usually picture solar panels, one of the most visible symbols of clean energy. But the recent fire at a cold storage warehouse in Boyle Heights, California, is a reminder that “green” infrastructure can still create very real pollution conditions.

The week-long fire at Lineage's cold-storage warehouse captured national attention because of its size, complexity, and the challenges firefighters faced in bringing it under control. The fire, which started on June 17, 2026, was reported to have originated on the roof of the 500,000-square-foot, cold-storage warehouse containing about 85 million pounds of frozen food. According to reports, the fire burned for several days before being declared a knockdown by the Los Angeles Fire Department (LAFD). The fire sent significant amounts of smoke into the air, prompting shelter-in-place and air quality advisories, and raising questions about what contaminants may have been released into the air, deposited onto nearby properties, and what contaminants are present in the runoff from the firefighting efforts.  
 

A fire defined by multiple challenges

The fire was difficult to extinguish because of the rooftop solar panels, the size of the warehouse, structural concerns, foam insulation, and leaking ammonia tied to the facility’s refrigeration system.

Combined with the challenges of safely gaining access to the interior of the building, the large solar panels had a significant impact on how firefighters attacked the warehouse fire.  Before solar panels, it was common for firefighters to vent the roof and deploy aggressive interior tactics.  As these panels are always live, even with a cutoff switch, firefighters may need to avoid the roof and, in many cases, only make a defensive exterior attack. In the case of the warehouse fire in California, the LAFD deployed a defensive, heavy-equipment-supported strategy given the sheer size of the building, structural instability, inaccessible fire areas, cold-storage construction, and the challenges posed by the rooftop solar panels. This included water drops, high-capacity water cannons and excavators. 
 

Evolving risk profiles and solar technologies

While the solar panels were not the sole reason the fire became a week-long incident, they do highlight broader property and environmental considerations that owners should evaluate before a loss occurs. Solar panels may produce clean energy during normal operation but can release toxins when burning or damaged. Depending on the panel type and construction, they can include glass, plastics, polymers, wiring, solder, and trace metals such as lead, cadmium, copper, tin, and other regulated materials. Under ordinary conditions, those materials are contained within the panel. During a fire, heat, smoke, fire suppression, water, debris, and particulate matter can release those materials as pollutants.

Fires involving solar panels can release pollutants such as smoke and particulate matter that can travel beyond the affected property, settling on neighboring buildings, vehicles, soil, stormwater systems, and other surfaces.  

For property owners, the most important takeaway is not whether solar panels caused the fire. Solar technology remains a valuable tool for reducing energy costs, improving sustainability, and supporting corporate environmental goals. Rather, the incident highlights a broader reality: as buildings incorporate new technologies and energy systems, risk profiles evolve as well. Understanding those risks and having the appropriate insurance and risk management strategies in place can make a significant difference when an incident occurs.

Property owners may face additional regulatory, cleanup, and testing obligations after a loss involving photovoltaic (PV) equipment. Environmental agencies, insurers, remediation contractors, and legal advisors may all become involved in assessing potential impacts and ensuring damaged materials are handled appropriately.

For owners, the financial exposure often extends beyond rebuilding the structure itself. Environmental investigations, debris removal, disposal of damaged materials, regulatory reporting, and remediation costs can become significant components of the overall loss.
 

Insurance blind spots many property owners overlook

Many property owners, tenants, lenders, and contractors are surprised to learn that pollution-related losses are not always fully addressed by traditional insurance programs. Since the introduction of the absolute pollution exclusion in the mid-1980s, bodily injury, property damage, environmental cleanup costs, and related liabilities arising from pollution conditions have often been excluded or significantly limited under standard general liability policies. While certain property policies may include extensions for decontamination, cleanup, or pollutant removal to insured property resulting from a covered cause of loss, the scope of these coverages varies substantially and often does not address the full range of environmental exposures that can arise following a major event.

The challenge extends beyond the mere presence of a hazardous substance, which alone may not constitute a pollution condition. Exposures frequently develop from smoke, airborne migration, off-site deposition, contaminated runoff, environmental investigation costs, debris management, emergency response activities, and third-party claims from neighboring property owners or occupants. These are classic pollution-condition issues, even if the original asset was part of a renewable energy system. 

Dedicated pollution coverage such as site pollution or contractors’ pollution, or combined coverage solutions such as general liability and site pollution or general liability and contractors pollution, can address exposures for owners, operators, tenants, contractors, and other parties. These policies are becoming more common, but they remain underused by many commercial insurance buyers.
Responsibility can be complicated. The panels may be on the building owner’s roof, but they may be owned or operated by someone else. The tenant, maintenance contractor, installer, roofing contractor, or refrigeration contractor could also be pulled into the conversation. In a fire involving multiple systems and multiple insureds, that can quickly turn into coverage disputes, indemnity arguments, litigation, and expensive legal fees.
 

Defining responsibility before a loss occurs

At the center of these situations are contractual agreements, which play a critical role in defining responsibility. Leased structures, such as triple net arrangements, often shift building liability to the operator, while warehouse agreements govern obligations between the operator and its customers. Additional complexity arises when third-party assets, such as rooftop solar panel systems, are involved, creating another layer of contractual and insurance dependencies. In the event of a loss, insurers across these parties may seek recovery from potentially responsible third parties, including equipment owners, maintenance providers, or manufacturers. However, available insurance limits among these parties may not be sufficient to fully offset large-scale losses.

These events highlight the importance of proactive risk management. Clear, aligned contractual terms, consistent insurance requirements across all stakeholders, and strong oversight of third-party vendors are essential in reducing exposure. Where similar risks exist across a portfolio - such as facilities with rooftop solar installations - lessons learned from one event should drive improvements in maintenance practices, vendor selection, and contractual protections. Strengthening these elements can help mitigate the likelihood and severity of future losses.
 

A balanced approach for property owners

The takeaways from the Lineage warehouse fire are not that property owners should avoid rooftop solar installations. Renewable energy will continue to play an important role in commercial real estate and industrial operations. Rather, the incident demonstrates the importance of understanding how evolving technologies interact with existing property risks.

Property owners need to understand that there is still a risk involved. Building owners, tenants, developers, lenders, and contractors should evaluate whether their insurance programs address pollution conditions arising from solar systems, cold-storage facilities, automated warehouses, battery storage systems, and other specialized assets that can create unique operational and environmental risk. These exposures should be addressed through risk management planning and insurance program design. Property owners who proactively evaluate these exposures, engage with qualified engineers and insurers, and ensure appropriate environmental and property coverage is in place will be better positioned to navigate both the immediate impacts of a loss and the long-term recovery process.

The Lineage fire is a reminder that environmental risk is not limited to traditional pollutants or legacy industrial sites. At Howden, we help clients look beyond the immediate property damage to understand the full spectrum of operational, environmental, contractual, and insurance risks so they can build greater resilience before a loss and recover more effectively when one occurs.
