Insights Category: Code Updates

As battery energy storage systems (BESS) continue to increase in size and deployment, questions surrounding fire propagation and exposure protection have become increasingly important. Previous editions of NFPA 855 relied on UL 9540A testing to evaluate thermal runaway behavior and fire propagation potential. However, those test protocols did not require a sustained fire event involving ignition of vented gases, leaving uncertainty regarding how some systems could perform under more severe fire conditions.

To address this concern, the 2026 edition of NFPA 855 introduces new Large-Scale Fire Test (LSFT) requirements. The intent is to provide stakeholders with a more realistic understanding of fire propagation hazards and support risk-informed decisions regarding system spacing, exposure protection, and overall installation design.

What Changed in the 2026 Edition?

The new requirements mandate large-scale fire testing for electrochemical battery energy storage systems and include ignition of vented gases as part of the evaluation. The testing methodology is incorporated into the newly released sixth edition of UL 9540A and is intended to better represent credible fire scenarios that may occur in real-world installations.

The testing is designed to evaluate:

  • Potential fire propagation between adjacent BESS units or groups
  • Ignition hazards to nearby structures and combustible materials
  • Appropriate separation distances between systems and exposures
  • The effectiveness of proposed fire protection strategies in limiting fire spread

Rather than focusing solely on whether thermal runaway occurs, the new requirements place greater emphasis on understanding the consequences of a fire event and demonstrating that fire spread remains appropriately controlled.

Why This Matters for Project Teams

The implications of the new testing requirements extend well beyond manufacturers.

Owners and developers may need to revisit preliminary site layouts, spacing assumptions, and project constraints based on LSFT results. Designers and engineers must understand how tested configurations relate to proposed installations, particularly when reduced separation distances or higher energy capacities are being considered. AHJs will increasingly rely on testing documentation and engineering analyses to verify that proposed designs appropriately limit fire spread to adjacent equipment, structures, and exposures.

As jurisdictions begin adopting the 2026 edition of NFPA 855, project teams should expect additional scrutiny regarding how testing results are applied to specific projects. Early coordination between owners, developers, manufacturers, designers, and AHJs can help identify potential challenges before they affect permitting, schedule, or project execution.

This broader perspective reflects an important industry shift: In addition to meeting a prescriptive requirement, compliance also entails understanding risk, evaluating system performance, and demonstrating that proposed solutions support the life safety objectives of the code.

Looking Beyond Compliance

The introduction of large-scale fire testing represents an important step in the continued evolution of energy storage safety. By evaluating BESS installations under more representative fire conditions, stakeholders gain additional data to support informed decisions regarding system design, fire protection strategies, and exposure protection.

For project teams, the key takeaway is that LSFT results should not be viewed solely as a testing requirement. They should be viewed as a tool for understanding project-specific risk and validating that proposed installations can safely achieve their intended performance while protecting people, property, and adjacent operations. This risk-informed approach aligns with the fundamental intent of NFPA 855 and the ongoing effort to improve public safety as energy storage technologies continue to evolve.

The 2024 North Carolina State Building Code has been approved but is not yet in effect statewide. While many projects will continue to be designed under the current code, North Carolina does provide a pathway for project teams to request use of the 2024 Code before its official effective date.

For owners and design teams evaluating opportunities under the 2024 Code, the decision involves more than selecting a few favorable provisions. Understanding how the newer code can be applied, and the broader implications of doing so, is an important part of developing an effective code strategy.

Considering Early Use of the 2024 Code

While North Carolina provides a mechanism to request approval of adopted rules before their effective date, project teams should carefully evaluate what that means for the project as a whole. The decision to pursue the 2024 Code should be considered within the context of the overall code strategy rather than focusing solely on individual provisions.

Early discussions with the Authority Having Jurisdiction can help establish alignment on the proposed code strategy and approval approach.

Looking Beyond Individual Code Provisions

As design teams evaluate the potential benefits of the 2024 North Carolina State Building Code, it is important to look beyond individual code provisions and consider the broader project implications. Updates related to mass timber construction, laboratory facilities, and other building features may create opportunities for certain projects. However, those potential benefits should be evaluated alongside any associated changes to referenced standards, approval requirements, and overall project strategy.

Factors such as newer editions of referenced codes, permitting strategy, approval pathways, project schedule, and coordination with stakeholders can all influence whether pursuing the 2024 Code is the right approach.

Ultimately, the goal is not simply to use the newest code available, but to identify the code strategy that best supports the project’s objectives while maintaining compliance and public safety.

Planning for a Successful Code Strategy

Early coordination among owners, architects, contractors, code consultants, and Authorities Having Jurisdiction can help establish a clear code basis and identify potential impacts to permitting, approvals, project schedules, and document coordination. While every project is different, establishing a consistent code strategy can reduce uncertainty and support informed decision-making throughout the design and construction process.

How Code Red Consultants Can Help

Navigating a code transition can be challenging, particularly when project schedules, permitting milestones, and design decisions do not align with adoption timelines. Code Red Consultants works with owners, architects, contractors, and Authorities Having Jurisdiction to help project teams evaluate available code pathways, understand the implications of evolving requirements, and develop strategies that support both project objectives and public safety. As the adoption process continues to evolve, early planning and informed decision making can help reduce uncertainty and position projects for success.

Code applicability and acceptance may vary based on project conditions and the Authority Having Jurisdiction. Project teams should confirm the appropriate code basis and approval process for their specific scope of work.

On October 15, 2026, the Massachusetts Board of Fire Prevention Regulations (BFPR) voted to promulgate the next edition of the Massachusetts Comprehensive Fire Safety Code, based on the 2024 edition of NFPA 1. Included in the new edition are provisions addressing the inspection and replacement of recalled sprinklers.

The new requirements are intended to strengthen the inspection of existing sprinkler systems and help identify recalled equipment that could affect system performance.

What Is Changing for Sprinkler Inspections?

Annual sprinkler inspections are already required in Massachusetts under NFPA 25. Under the new provisions, the sprinkler list and spare sprinklers will also need to be compared against sprinkler recalls issued by the Consumer Product Safety Commission (CPSC).

If recalled sprinklers are identified, the sprinkler system will be considered impaired. The local fire department must be notified of the impairment, and the recalled sprinklers must be replaced expeditiously.

Lessons Learned from the Gabriel House Fire

The new provisions were developed following the tragic July 13, 2025 fire at Gabriel House in Fall River, Massachusetts, which resulted in the deaths of 10 residents.

The code change proposal was submitted by Fall River Fire Captain Joshua Hetzler and demonstrates how lessons learned from significant fire events can lead to meaningful changes in fire protection and life safety regulations.
Code Red Consultants’ Jen Hoyt, P.E., serves as a public representative on the BFPR and voted to approve the new fire code regulations.

What to Expect Next

Although the BFPR has voted to advance the new regulations, the adoption process is not yet complete. The updated code must proceed through the remaining governmental and public hearing process before becoming effective.

Building owners and facility teams should be aware of the upcoming requirements, particularly for existing buildings with older sprinkler systems, and be prepared to address recalled sprinklers identified through future inspections.

How Code Red Consultants Can Help

As Massachusetts moves toward adoption of the new Fire Code, our team can help clients understand upcoming requirements, evaluate their impact, and develop practical solutions that balance compliance, risk, and life safety.

Code Red Consultants provides risk-informed guidance rooted in public safety, helping building owners, facility teams, and design professionals navigate evolving fire protection and life safety requirements. Our experience across code consulting, fire protection design, existing facilities, and coordination with Authorities Having Jurisdiction allows us to bring an integrated perspective to complex compliance challenges.

Construction and renovation projects in healthcare facilities often require temporary impairments to fire protection and life safety systems. While Interim Life Safety Measures (ILSMs) provide an important framework for managing many of these conditions, some impairments introduce risks that extend beyond what a standard ILSM process is designed to address.

This is particularly important in hospitals, where the risk profile is elevated because many patients cannot evacuate independently during a fire. Rather than leaving the building, patients often must remain in place or be relocated by hospital personnel to protected areas within the facility. Fire alarm systems, sprinkler systems, compartmentation, egress, and emergency response procedures therefore function as an interdependent life safety strategy; when any one of these elements is significantly impaired, it can directly affect the staff’s ability to protect and safely relocate patients.

UNDERSTANDING THE RISK

Certain impairment conditions often warrant additional evaluation, including:

  • Fire alarm impairments lasting more than eight hours (NFPA 72).
  • Sprinkler impairments lasting more than ten hours (NFPA 25).
  • Changes to fire department access or emergency response procedures.
  • Significant impacts to egress routes (NFPA 101).
  • Disruptions to smoke or fire compartmentation relied upon by a hospital’s emergency plan (NFPA 101).

In these situations, the challenge is understanding how the impairment affects the facility’s overall life safety strategy, particularly in buildings where occupants may not be capable of self-evacuation.

COMMON CHALLENGES DURING CONSTRUCTION

A common mistake when evaluating an impairment is treating it as an isolated issue rather than assessing its impact on building operations, emergency procedures, and other fire protection features.

Additional challenges can arise when temporary conditions trigger permitting or approval requirements. For example, temporary modifications to elevator recall devices may require coordination with both an elevator official and the fire department depending on the jurisdiction. More jurisdictions are also requiring impairment planning as part of NFPA 241 construction fire safety programs, which are required by both the International Building Code and NFPA 101, the Life Safety Code. Early coordination with facility staff, contractors, designers, and Authorities Having Jurisdiction (AHJs) can help identify these requirements before they impact project schedules.

PLANNING FOR SAFE, CONSTRUCTIBLE SOLUTIONS

Effective impairment planning balances public safety, hospital operations, construction activities, and regulatory requirements. This often requires evaluating the affected systems, duration of the impairment, impacted occupants, temporary mitigation measures, construction sequencing, and approval requirements.
The most successful approaches are both technically sound and practical to implement. By understanding how fire protection and life safety systems interact, project teams can develop solutions that protect occupants while remaining constructible and manageable in active healthcare environments. This reflects the importance of public safety first and engineering solutions grounded in real-world application.

Los Angeles continues to see interest in converting underutilized office buildings into residential housing. While recent adaptive reuse initiatives have reduced zoning barriers, project teams have still faced a recurring question: how will building and fire code requirements be applied when an office building changes occupancy to residential?

To address that uncertainty, the Los Angeles Department of Building and Safety (LADBS) issued Information Bulletin IB-BC-2026-164, Change of Occupancy from Office to Residential, on September 14, 2026. The bulletin does not create new code requirements. Instead, it clarifies how LADBS and the Los Angeles Fire Department (LAFD) intend to apply existing provisions of the California Existing Building Code (CEBC) and California Building Code (CBC) to office-to-residential conversion projects.

Choosing a Compliance Path Early

One of the most significant clarifications in the bulletin is the requirement for project teams to identify a compliance methodology early in the permitting process. Design professionals must select either the Prescriptive Compliance Method under CEBC Section 506 or the Work Area Compliance Method under CEBC Chapter 10 and document that approach in the permit submission.

Because a conversion from office to residential is treated as a change to a higher-hazard occupancy, the selected compliance method can have a substantial impact on project scope. Depending on the approach, required upgrades may extend beyond the immediate work area and affect other portions of the building. While the Work Area Compliance Method may provide additional flexibility for some existing buildings, both approaches require careful evaluation of fire protection, means of egress, accessibility, and structural provisions.

Understanding these implications early can help owners and design teams make informed decisions regarding cost, schedule, and feasibility while reducing the likelihood of unexpected requirements later in the approval process.

High-Rise Fire Protection Requirements Remain a Key Consideration

The bulletin also clarifies several important high-rise requirements that continue to apply when converting office buildings to residential occupancy. Buildings exceeding 120 feet above the lowest level of fire department vehicle access are generally expected to provide at least one fire service access elevator meeting CBC Section 3007 requirements, subject to approved modifications by LADBS and LAFD. Existing passenger elevators are not automatically considered compliant fire service access elevators and may require significant evaluation.

Similarly, converted residential high-rises must comply with applicable requirements for automatic sprinkler protection, fire alarm systems, smoke control, standpipes, fire pumps, emergency power, emergency responder radio coverage, and fire command centers where required by the code. The bulletin also outlines circumstances under which modifications to smokeproof enclosure requirements may be considered for existing buildings.

These provisions demonstrate that office-to-residential conversions often involve much more than architectural modifications. Successful projects require coordination between multiple disciplines to evaluate how existing building systems align with current residential occupancy requirements.

Reducing Uncertainty for Adaptive Reuse Projects

While office-to-residential conversions remain complex, the bulletin provides valuable insight into several topics that have generated uncertainty on recent projects. LADBS confirms that exterior wall ratings generally do not increase because of the conversion, existing non-rated openings may often remain, and buildings without an existing emergency helicopter landing facility are not required to add one solely because of the occupancy change. The bulletin also establishes a documented path for certain smokeproof enclosure alternatives and clarifies expectations related to fire service access elevators.

At the same time, the bulletin reinforces that no guidance document can replace a project-specific code evaluation. Existing building conditions, selected compliance methods, planned renovations, building height, and system capabilities can all influence the feasibility of a proposed conversion. Project teams should view the bulletin as a tool for navigating complexity with greater clarity rather than a substitute for a comprehensive building analysis. This approach supports decisions that balance compliance, constructability, project goals, and public safety.

How Code Red Consultants Can Help

Office-to-residential conversions require project teams to evaluate existing building conditions, understand changing occupancy requirements, and coordinate compliance strategies across multiple disciplines. As adaptive reuse activity continues to grow, early code analysis can help identify potential challenges before they affect project schedules, budgets, or approvals.

Code Red Consultants works with owners, developers, architects, contractors, and authorities having jurisdiction to evaluate existing buildings, navigate complex code requirements, and support adaptive reuse projects from planning through permitting. Drawing on experience across codes, jurisdictions, project types, and stakeholder perspectives, our team helps clients make confident, informed decisions while developing practical compliance strategies aligned with code intent and project objectives.

Code requirements, interpretations, and enforcement practices may vary by project, building condition, and authority having jurisdiction. Project teams should confirm applicability based on their specific scope and location.

The 2026 edition of NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, refines and clarifies the standard’s approach to Explosion Control and Prevention, with a notable shift toward performance-based justification and clearer terminology. Throughout the chapter, language has been standardized to consistently reference “Explosion Control and Prevention,” improving alignment with NFPA 68, Standard on Explosion Protection by Deflagration Venting, and NFPA 69, Standard on Explosion Prevention Systems.

New Requirements for Energy Storage System Installations

Energy Storage Systems (ESS) that require explosion control and prevention must comply with NFPA 855 Section 9.7.6.7. This section introduces the following changes from the 2023 edition of NFPA 855:

  1. Clarifies that an explosion control and prevention system is required when the average vented gas concentration inside the ESS enclosure can accumulate beyond 25 percent of the Lower Flammability Limit (LFL),
  2. Acknowledges that localized gas pockets above 25 percent of the LFL likely exist inside the ESS enclosure and, therefore, a partial volume deflagration analysis must be conducted in accordance with NFPA 68.
  3. Requires that:
    1. Vented gases do not migrate between interconnected ESS enclosures, thereby limiting flame propagation and cascading events.
    2. The suitability of the NFPA 69 Explosion Control and Prevention system during a thermal runaway event should be demonstrated.
    3. An impact study of the logic used to determine the sequence of events for discharge when the ESS is equipped with a fire suppression system other than water must be submitted to the AHJ for approval.

While NFPA 68 explosion control systems were previously acceptable as a stand-alone explosion control method, an NFPA 69 Combustible Concentration Reduction System must also be provided for the ESS, resulting in greater resiliency and protection for the equipment, service personnel, and first responders.

Explosion Control & Prevention System Requirements

The Explosion Control and Prevention system is considered a critical safety system and must comply with emergency power supply, notification, commissioning, inspection, and testing requirements, including but not limited to:

  1. Compliance with NFPA 3, Standard for Commissioning of Fire Protection and Life Safety Systems (NFPA 855 Section 9.7.4.3) and NFPA 4, Standard for Integrated Fire Protection and Life Safety System Testing (NFPA 855 Section 9.7.4.2)
  2. Compliance with NFPA 110, Standard for Emergency and Standby Power Systems, or NFPA 111, Standard on Stored Electrical Energy Emergency and Standby Power Systems.
  3. Commissioning under the direction of a registered design professional,
  4. Confirm airflow against NFPA 69 evaluation reports.
  5. Undergo inspection & testing to confirm the systems operate as designed.

One year after the Gabriel House fire, Massachusetts has finalized comprehensive assisted living safety reforms designed to strengthen resident protections across the Commonwealth. The new regulations, which include updates to 651 CMR 12.00, introduce enhanced fire safety measures, expanded emergency preparedness requirements, increased expectations for staff training, and greater accountability for assisted living operators. These changes reflect a continued focus on improving resident safety and reducing the risk of similar tragedies in the future.

Understanding the New Requirements

The finalized regulations place a greater emphasis on emergency readiness at assisted living residences. While fire protection systems remain an important component of resident safety, the new requirements recognize that emergency preparedness also depends on staff training, emergency planning, resident support, and operational procedures. Collectively, these measures are intended to improve how facilities prepare for, respond to, and recover from emergency events.

The reforms also increase transparency and accountability by establishing clearer expectations for operators and strengthening requirements intended to support residents, families, and regulatory oversight. These changes reflect a broader commitment to ensuring that safety planning extends beyond compliance and considers the unique needs of assisted living populations.

Why Early Evaluation Matters

For owners and operators of assisted living residences, understanding how the revised regulations apply to existing facilities will be an important part of maintaining compliance and supporting resident safety. Evaluating emergency preparedness procedures, staff training programs, and fire protection and life safety code features early can help identify gaps and establish a clear path toward implementation.

As regulatory requirements continue to evolve, successful implementation often requires coordination among facility operators, regulatory agencies, and authorities having jurisdiction. This collaborative approach helps ensure that safety measures are aligned with both the intent of the regulations and the practical realities of facility operations. Consistent with the goals of the reforms, public safety remains the primary driver behind these requirements and the decisions that support them.

Energy Storage System (ESS) technologies are constantly evolving, and it is expected that the codes and standards governing these systems will continue to change as regulations work to keep pace with technological advancements. The 2026 edition of NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, continues the reorganization effort that started with the 2023 edition along with the introduction of several new sections, and section updates to best address safety concerns.

First, the standard expands the list of ESS technologies that are covered under NFPA 855 in Chapter 1, adding battery types such as Zinc-based, Iron-air/aqueous, Sodium-ion, and Nickel-hydrogen, as well as different types of capacitors. Alongside restructuring the standard, the new edition also expands on both Chapter 4, General, and Chapter 9, Electrochemical Energy Storage Systems, to help provide further guidance on the installation and design of ESS, with an emphasis on electrochemical systems.

Key Changes Affecting ESS Design and Installation

Some high-level changes to the 2026 NFPA 855 that are expected to impact the design and installation of battery ESS include:

  • A requirement for all indoor and outdoor ESS installations of the standard, to be provided with a Hazard Mitigation Analysis (HMA).
  • An expansion of the requirements for Emergency Planning and Training. Separate documents are now required for first responders in the form of an Emergency Response Plan (ERP) and for ESS personnel in the form of an Emergency Operations Plan (EOP) to provide the most suitable information for each audience.
  • Requirements for the ESS Owner/Operator to provide fire department training beyond the initial training before the ESS arrives on site, to now include fire department training on an annual basis.
  • In addition to the UL 9540A testing, the 2026 edition now requires a large-scale fire test in which vented gas must be ignited so that the explosion and fire propagation hazards associated with each design can be adequately evaluated.
  • ESS-based electrochemical technologies prone to thermal runaway must be equipped with Thermal Runaway Propagation Prevention (TRPP) Protection Systems. The new section provides requirements beyond being listed for UL 9540, such that TRPP systems need to meet additional system and testing requirements.
  • ESSs for which an explosion hazard has been identified during normal operation or a thermal event now require a more detailed deflagration analysis with regards to partial volume deflagration and system design. Additionally, these ESS must also be provided with a Combustible Concentration Reduction System (CCRS) in accordance with NFPA 69.

Early Coordination & How Code Red Consultants Can Help

As is the case with any rapidly evolving technology, early coordination is an important component of successful ESS projects. Collaboration with local AHJs supports compliance and approvals while also helping first responders understand the unique hazards associated with ESS installations and prepare for potential emergency events.

The Maryland Department of Housing and Community Development (DHCD) has introduced a new requirement that affects future Low Income Housing Tax Credits (LIHTC) projects, effective with the 2026 Qualified Allocation Plan (QAP) release on April 8, 2026. Under the current plan, affordable housing developments pursuing LIHTC in Maryland are required to engage a third‑party accessibility consultant to support compliance throughout the project lifecycle.

What Changed

The 2026 QAP includes a new provision requiring project teams to retain a third‑party accessibility consultant to assist with verification of compliance. The consultant’s role typically includes design review, construction-phase coordination, and documentation confirming compliance prior to project completion. The new requirement reflects a broader trend toward earlier and more formalized accessibility coordination within housing programs.

Key Dates and Milestones

  • Draft 2026 QAP Released: Early 2026
  • Potential Requirement Start: 2026 LIHTC application cycle
  • Final Adoption: April 8, 2026

We help teams navigate complex regulatory conditions and align accessibility considerations with broader code and life safety requirements.

On April 24, 2026, the Massachusetts Department of Fire Services and Board of Fire Prevention Regulations (BFPR) published and promulgated a new edition of 527 CMR 12.00, the Massachusetts Electric Code. 527 CMR 12.00 is an amended version of the 2026 Edition of the National Electric Code (NEC), produced and published by the NFPA as NFPA 70. Note that the applicable Massachusetts Electrical Code vests with the application date of the electrical install permit, rather than the date a building code permit may have been applied for.

The 2026 Edition of NFPA 70 isn’t just a routine update – it is a comprehensive modernization of the code designed to keep pace with a rapidly shifting energy landscape. As our world becomes more interconnected, the NEC has undergone a significant structural shift to better integrate data, power, and high-voltage systems.

Key highlights of the 2026 NFPA 70 revisions:

• Enhanced Transparency: Arc-flash labeling is no longer restricted by the 1000-amp threshold. Now, more equipment than ever requires clear labeling, including the specific date of the safety assessment.

• Limited Energy Systems Definition: Article 100 introduces a formal definition for “Limited Energy Cable” to replace outdated terminology and better cover modern low-voltage systems.

• Streamlined Integration: In a major move for usability, the code has moved many communication systems out of Chapter 8 and into Chapters 1–7, reflecting how data and power now function as one.

• Safety in the Green Sector: From updated load calculations for EV infrastructure to stricter installation rules for Energy Storage Systems (ESS), the 2026 edition provides a safer roadmap for renewable energy.

• GFCI Expansion: Ground-Fault Circuit Interrupters (GFCIs) are required in more non-dwelling areas, with new Class C, D, and E definitions for special applications.

• Working Space and Egress: New requirements clarify working space around equipment, including a 24-inch mandated egress path.

Detailed coordination with the design team’s engineer of record is recommended if an electrical permit was not applied for prior to the adoption of this new code.
