Mitigation as market advantage: How builders are redefining insurability in a hard market

As insurance markets tighten across wildfire, wind, flood and freeze zones, mitigation is shifting from an optional upgrade to a baseline requirement, forcing homebuilders to rethink how resilience factors into construction, sales and long-term strategy. Rising reinsurance costs and record catastrophe losses have made carriers more selective, underwriting communities individually and rewarding demonstrated risk reduction.

In this conversation, Gabriel Salazar, Vice President of Agency Support Services at Westwood Insurance Agency, draws on more than two decades of builder-focused property insurance experience to explain how measures like Insurance Institute for Business & Home Safety (IBHS) wildfire standards, smart water shutoff valves and embedded insurance can support stronger insurability, improve carrier confidence and help stabilize premiums over time.

Which resiliency features actually influence insurability and premium stability

HousingWire: What specific mitigation (building and neighborhood resiliency) features are now showing a clear correlation with lower premiums or improved insurability across Westwood’s portfolio data?

Gabriel Salazar: Building and neighborhood resiliency has become a real focus, especially in California. One example is the IBHS wildfire preparedness standards, which allow homeowners to upgrade their properties in tiers to better withstand fire risk. That was highlighted during the Palisades fire, where one IBHS-prepared home remained standing while surrounding homes were total losses. We often highlight that example when speaking with customers and carriers considering business in California because it demonstrates a clear correlation: homes focused on risk mitigation tend to experience fewer losses, which can support more stable premiums and more consistent insurability over time.

Water damage is a frequent source of loss. We’re working with a carrier that offers an E&S product in California that includes a complimentary smart water shutoff valve. The device detects abnormal water flow and automatically shuts off the main valve, helping prevent costly interior water damage from broken pipes or plumbing failures. While large natural disasters dominate headlines, it’s often the $25,000 to $50,000 water claims that steadily impact carrier loss ratios and profitability nationwide. Programs like this address one of the most common and expensive drivers of loss, providing practical mitigation that benefits both insurers and homeowners.

In some higher-risk areas, we are also seeing mitigation shift from a “nice-to-have” to a prerequisite for securing coverage at all. Carriers increasingly require certain wildfire, water, or wind-resilience measures simply to provide a market for a community, so mitigation is becoming foundational to maintaining insurability, not just a support for pricing stability.

Why carrier alignment and risk transparency matter more than ever

HW: In today’s volatile insurance environment, what are homebuilders most often unclear about regarding how carriers view mitigation investments?

GS: Builders and insurers need clearer alignment around profitability and loss drivers. When builders understand where carriers are incurring losses, which states are underperforming, and where insurers are seeking growth, it changes the conversation.

Our account management team works directly with builders to share that insight. In some oversaturated ZIP codes, carriers may still deploy capacity if specific mitigation standards are in place. These decisions are increasingly data-driven and community-specific.

Diversification is another important shift. Historically, a single carrier might insure nearly every home in a community. Today, spreading risk across multiple insurers is often more sustainable. That requires coordination and transparency between carriers and builders. The more intentional the collaboration, the stronger the long-term stability of the community’s insurance ecosystem.

Reframing mitigation as a buyer value proposition

HW: Can you walk us through how homebuyers interpret mitigation as a value proposition — where it resonates emotionally and where they need more reassurance or clarity?

GS: With homebuyers, it begins with incentives and clarity. New construction already provides advantages such as updated systems and modern materials, which can qualify for lower premiums. When you add mitigation features like water shutoff valves, IBHS wildfire standards, or ember-resistant vents, the value becomes tangible, not necessarily in the form of lower premiums, but in stronger insurability and reduced risk exposure.

For many homebuyers, this is the largest investment of their lives. They cannot control property taxes, but they can influence insurance costs and risk exposure. When mitigation is framed as a way to stabilize monthly premiums and protect long-term affordability, it resonates both emotionally and financially.

Our agents lead with education early in the process so buyers understand that the home is not only new but built to be resilient and insurable.

HW: How can Westwood advise homebuilders on how to frame mitigation in their sales and marketing — not with fear, but with trust and readiness?

GS: Our approach to guidance is handled builder by builder. We don’t use a standardized handout or broad marketing campaign with flyers for every sales office. Instead, our account management team works directly with each builder, educating them on what steps make sense in their specific region or community. Because we collaborate with builders nationwide, our strategy varies by market, and we tailor our guidance accordingly.

HW: From your experience with homebuilders across regions, what kinds of homebuilders are leading the way in integrating mitigation into the purchase journey — and what makes their approach work?

GS: Working with America’s largest home builders, we see that despite regional differences, all builders — even regional ones — are scaling preventative measures beyond standard code requirements. They are intentionally building safer, more disaster-resilient communities and clearly communicating this advantage to insurers and homebuyers.

For example, in wildfire-prone markets such as Santa Clarita, California, some builders have invested in infrastructure enhancements that go beyond minimum proximity standards for fire protection. Others are intentionally building communities that outperform surrounding areas in disaster resilience and clearly communicating those investments to carriers and buyers.

Mid-sized and regional builders are also tailoring mitigation to local exposures and exceeding baseline requirements. That proactive posture strengthens carrier confidence and positions the home as a stronger long-term investment.

How embedded insurance strengthens the mitigation narrative

HW: How does embedded insurance change the conversation around mitigation — does it help builders surface the value of these features more effectively?

GS: Embedded insurance creates transparency and efficiency for the builder and homebuyer. Because we understand exactly how the home is constructed, we can apply appropriate discounts upfront. We are not verifying features at the closing table or reassessing underwriting details late in the process.

Sales teams provide construction data early in the process, allowing us to price accurately and incorporate mitigation-based discounts before closing. That transparency builds buyer confidence and reduces friction in the transaction. It also reinforces the value of the builder’s mitigation investments by supporting stronger insurability and long‑term cost stability.

What has changed in carrier expectations across risk zones

HW: What has changed over the past 12 to 18 months in carrier expectations for family homes in wildfire, wind, flood or freeze zones?

GS: Many mitigation features that were once considered optional are becoming baseline expectations. We are operating in a hard market, and carriers are underwriting communities individually rather than broadly accepting new construction.

Rising reinsurance costs have intensified scrutiny. Stronger wildfire defensible space measures, mandatory flood coverage in certain zones, and enhanced wind or freeze protections are increasingly required. What was once viewed as an upgrade is often necessary to secure coverage. New construction remains attractive, but acceptance is no longer automatic. Insurability now depends on demonstrated resilience.

Why mitigation is now a strategic imperative for builder leadership

HW: What should homebuilder C-suite leaders understand about insurance and mitigation right now?

GS: Today, intentional leadership isn’t a mere checkbox. It has to be about driving meaningful change for a greater purpose. We are talking about people’s homes, their largest asset and their sense of security. When builders invest in meaningful mitigation, they are reducing risk, stabilizing rates, and strengthening their competitive position.

Recent billion-dollar wildfire losses have reshaped the market. Carriers are increasing their focus on sustained mitigation education and clearer expectations. Builders who lean into that collaboration will be better positioned for long-term insurability and growth.

Mitigation is no longer simply a requirement. It is a strategic advantage.
