California’s Sustainable Insurance Strategy: Progress, Reality, and What Homeowners Should Actually Expect

California’s insurance market has spent the last several years tightening. Fewer options, higher premiums, stricter underwriting, and growing dependence on the FAIR Plan have become the norm.

That’s why California’s new Sustainable Insurance Strategy (SIS) — taking effect July 1, 2026 — is getting so much attention.

The strategy is designed to encourage insurance companies to write more policies in wildfire-prone areas by allowing carriers to use more advanced catastrophe modeling and pricing tools. In exchange, insurers are expected to increase availability in distressed areas and help reduce reliance on the FAIR Plan.

The recent announcements from Mercury Insurance and Travelers Insurance are early examples of carriers stepping into the program.

That’s encouraging.

But it’s also important to keep expectations realistic.

Quick Overview: What the Sustainable Insurance Strategy Actually Means

• California is allowing carriers to use more advanced wildfire modeling

• In exchange, insurers are expected to write more policies in distressed areas

• Mercury has committed to adding approximately 70,000 policies over two years

• Travelers has also announced participation in the strategy

• This does not mean insurance suddenly becomes easy or inexpensive

• Underwriting will likely remain strict, especially early on

• Homeowners should still review every renewal carefully

What Is the Sustainable Insurance Strategy?

The Sustainable Insurance Strategy is California’s attempt to stabilize the homeowners insurance market.

In simple terms, the state is saying to insurance companies:

“If we allow you to price wildfire risk more accurately, you need to write more business in California.”

For years, many carriers argued that existing regulations prevented them from properly pricing catastrophic wildfire exposure. The new strategy gives carriers more flexibility in how they evaluate and price risk.

But there’s an important tradeoff:

More availability may also mean higher premiums in hard-to-insure areas.

This is not a “premium reduction program.” In many cases, the strategy is actually allowing carriers to charge more adequate pricing for wildfire exposure.

That may improve long-term availability — but it does not automatically improve affordability.

Mercury Is First Through the Door

Mercury recently became the first insurer approved under the strategy and announced plans to:

• Expand wildfire mitigation discounts

• Increase policy availability

• Focus on FAIR Plan depopulation

• Grow policies in force by approximately 15% over two years

Travelers has also recently announced plans to participate.

That’s meaningful because it signals that major carriers are at least beginning to re-engage with the California market rather than simply shrinking their footprint.

The FAIR Plan Numbers Tell the Bigger Story

Here’s the reality: even meaningful carrier participation is still relatively small compared to the size of the overall problem.

California FAIR Plan residential policy counts and exposure totals have grown dramatically in recent years.

The FAIR Plan now represents hundreds of thousands of residential policies and hundreds of billions in insured exposure statewide

So while Mercury adding roughly 70,000 policies is absolutely positive, it’s still only a small piece of the broader market challenge.

This is progress — not a magic reset button.

What Homeowners Should Realistically Expect

1. Underwriting Will Still Be Strict

Even with the new strategy, carriers are still going to be selective.

Expect continued focus on:

• Defensible space

• Roof age and condition

• Prior losses

• Brush proximity

• Property access

• Home hardening features

Early participation does not mean relaxed underwriting.

2. Availability May Improve Slowly

Some carriers may remain cautious until deadlines approach or until they need additional policies to satisfy participation expectations.

In other words:

The market may loosen gradually — not overnight.

3. Pricing Will Still Be Challenging

One of the biggest misunderstandings about the Sustainable Insurance Strategy is the idea that it will suddenly lower premiums. That is unlikely.

The strategy is designed more around:

• Market stability

• Increased participation

• Improved availability

…than broad premium reductions.

Practical Steps to Lower Your Home Insurance Premiums

You can take several actions to reduce your insurance costs while maintaining adequate protection:

• Mitigate wildfire risk: Clear brush, maintain defensible space, and use fire-resistant landscaping.

• Upgrade your home: Install fire-resistant roofing, reinforce windows, and update electrical systems.

• Increase your deductible: Choose a higher deductible if you can afford the out-of-pocket expense.

• Bundle policies: Combine home and auto insurance for multi-policy discounts.

• Shop around: Compare quotes from multiple insurers to find the best rate.

• Maintain a good credit score: Insurers often use credit-based insurance scores to set rates.

  
  

These steps align with California’s sustainable insurance strategy by reducing risk and encouraging responsible homeownership.

What We Think This Means for the Future

This strategy is probably the most meaningful structural shift California has made in years regarding insurance availability.

That’s important.

But the reality is:

• The market did not tighten overnight

• It probably won’t reopen overnight either

What does seem likely is:

• More gradual movement

• More mitigation-based underwriting

• More documentation requirements

• More carriers cautiously testing the waters

For homeowners, the best move is still:

• Review every renewal

• Stay proactive

• Improve mitigation where possible

• Re-shop when opportunities arise

The days of “set it and forget it” homeowners insurance are probably over for now.

Bottom Line

California’s Sustainable Insurance Strategy is a positive development — especially compared to years of contraction and uncertainty.

But it’s important to understand what it is and what it isn’t.

It may improve long-term availability and encourage more carrier participation, but it does not instantly solve affordability or underwriting challenges.

Still, for the first time in a while, there are at least signs of forward movement.

If you’ve been impacted by non-renewals, FAIR Plan placement, or rising premiums, it’s important to review your options regularly as the market evolves.
