2025 Trends in Professional Liability Insurance: What Architects Need to Know Now

Each year, the AIA Trust, in collaboration with the American Council of Engineering Companies (ACEC) and the National Society of Professional Engineers (NSPE), conducts in-depth interviews with professional liability insurance carriers to better understand the state of the market, emerging risks, and evolving claims trends affecting design professionals.

The 2025 conversations point to a market that is largely stable—but increasingly nuanced. While overall conditions remain favorable, carriers are watching specific risk factors more closely, and expectations around documentation, contracts, and firm practices continue to rise.

Below are the key insights architects should keep in mind as they plan for the year ahead.

A Market That’s Stable—With a Few Watchful Eyes

Good news first: the professional liability insurance market for architects is stable and softening, with ample capacity and strong competition among carriers. Insurers continue to actively seek A/E firms, and this competition is helping keep pricing in check.

Looking ahead to 2026, most carriers anticipate flat to modest rate increases, generally in the 0–5% range. This continues a multi-year pattern of gradual adjustments rather than abrupt swings.

That said, pricing remains closely tied to fundamentals. Annual billings and claims history continue to be the primary drivers of premium calculations. As firms grow, premiums naturally follow—but strong, consistent risk management practices can help stabilize rates over time by reducing both claim frequency and severity.

Another trend gaining traction is the demand for higher insurance limits, particularly for large-scale and luxury residential projects. Coverage limits are increasingly shaped by project scope and contractual requirements, reinforcing the importance of reviewing insurance needs as projects and firm profiles evolve.

Where Underwriters Are Paying Closer Attention

While overall market conditions are favorable, carriers consistently flagged certain exposures that continue to challenge underwriting decisions.

High-risk project types remain a focal point, including design-build delivery, large infrastructure projects, multi-family residential and condominium work, and projects involving geotechnical services. Rising labor and material costs, combined with broader societal trends, are also increasing overall claim expenses.

One issue insurers emphasized repeatedly is the rise of “nuclear verdicts”—jury awards exceeding $100 million—which are becoming more common in litigation-heavy states and are driving long-term cost concerns across the insurance industry.

Contract quality also remains a critical concern. Poorly negotiated agreements and unclear scopes of services frequently surface in claims, with particular scrutiny on indemnification provisions, warranty or guarantee language, arbitration clauses, and attempts to elevate the standard of care beyond what is insurable.

What Claims Data Is Telling Us

Claims activity continues to cluster around familiar project types. The highest percentage of claims arise from commercial, multi-family residential and condominium projects, transportation work, and single-family residential projects.

Across these sectors, the most common drivers of claims include technical errors, inadequate project management (often tied to contractual terms), and breakdowns in communication or documentation.

Several broader trends are compounding claim severity. Social inflation and rising litigation costs are pushing claim values higher, particularly in transportation, multi-family, and residential project types. High-severity claims—especially those involving structural failures or bodily injury—are increasing, and carriers are watching the potential for class-action litigation with growing concern.

Operational pressures inside firms are also playing a role. Staffing shortages and high turnover can contribute to coordination gaps and construction defects, while mergers and acquisitions often introduce new exposure related to legacy liabilities and continuity of coverage.

Carriers continue to strongly encourage early claims reporting and pre-claims assistance. While most claims are still reported within the first three years of a project, resolution timelines are lengthening and overall claim severity is increasing, reinforcing the value of early engagement and proactive risk mitigation.

Emerging Topics Shaping the Conversation

Two issues surfaced repeatedly in 2025 discussions: artificial intelligence and climate change.

AI is now part of many placement and renewal conversations. Most A/E firms report using AI as a supplementary tool rather than for full design creation, and carriers are focused less on the technology itself and more on quality control, professional judgment, and potential copyright concerns. From a liability perspective, the standard remains unchanged: negligence is evaluated based on outcomes and professional responsibility, regardless of the tools used.

Climate change continues to emerge within the broader framework of sustainability and Environmental, Social, and Governance (ESG) considerations. As climate events become more frequent, design professionals are increasingly expected to adapt their practices to evolving standards of care—often beyond minimum code requirements. To date, carriers have not seen major claims tied directly to climate-related advice or carbon-neutral or net-zero commitments, but they view this as an area requiring proactive planning.

At the same time, alternative project delivery methods—such as P3 and design-build—are reshaping risk profiles and coverage needs, reinforcing the importance of aligning insurance strategies with how work is delivered.

Risk Management: Still the Most Powerful Tool

Across every interview, one message was consistent: effective risk management starts with communication. Clearly defining and managing client expectations—beginning with a well-scoped agreement—remains the single most effective way to reduce exposure.

Carriers emphasized the importance of strong contracts with appropriate risk allocation, including careful review of scope language, flow-down provisions, and liability limitations. Many insurers expressed a preference for firms that actively negotiate more favorable contractual terms and seek guidance before issues arise.

Additional best practices highlighted by carriers include regular reviews of insurance needs as firms evolve, thoughtful client selection and risk assessment, addressing climate considerations explicitly in contracts, maintaining appropriate office-based oversight, and investing in staff training and education.

Firms are strongly encouraged to review the terms, conditions, exclusions, and restrictions within their professional liability policies so there are no surprises regarding coverage availability in the event of a claim.

Turning Insight Into Action

Every insurer surveyed offers robust risk management and educational resources—underscoring their role not just as underwriters, but as long-term partners in professional practice.

The AIA Trust complements these offerings with a broad collection of tools, guides, and on-demand webinars developed specifically for architects. These resources are designed to support stronger contracts, more resilient internal processes, and informed decision-making at every stage of practice.

For firms evaluating their coverage options, the AIA Trust’s Professional Liability Insurance Database makes it easy to compare carriers, coverage features, and benefits side-by-side. Many of the insurers participating in this annual review are included—allowing firms to move from insight to action efficiently.

In addition, the AIA Trust offers professional liability insurance coverage tailored exclusively for AIA members. Whether you’re exploring new coverage or simply reassessing your current program, it’s a valuable starting point as your firm’s risk profile evolves.

Key Takeaways for A/E Firms

• Maintain strong risk management fundamentals through clear contracts, regular insurance reviews, and ongoing staff training

• Monitor emerging risks, including climate change, AI, and evolving project delivery methods

• Engage proactively with carriers by using educational resources, contract review programs, and early claims assistance
