San Diego homeowners are losing insurance: what should you have inspected?

California homeowner insurance premiums have risen 84% since the end of 2020, according to research from Stanford's Center for Energy and Environmental Policy. The FAIR Plan (California's insurer of last resort) now covers approximately 5% of the state's single-family homes, up from 1.5% in December 2020. In 46 of 58 California counties, insurer nonrenewals outnumbered new policies written. And San Diego County, where the typical home value is approximately $928,000, sits squarely in the middle of it.

If you've received a nonrenewal notice, watched your premium double, or been told your home needs specific improvements before a carrier will write or renew your policy, you're not alone. The insurance market in California has fundamentally changed over the past several years, driven by wildfire losses, reinsurance costs, and regulatory shifts. And one of the most direct things a homeowner can do to improve their insurability is to address the physical conditions of their property that carriers evaluate.

This is where a home inspection intersects with the insurance conversation. The items that make a home harder to insure are often the same items that show up on an inspection report: roof condition, electrical panel type, plumbing condition, defensible space, and the building envelope. Understanding what carriers look at, and addressing the conditions you can control, gives you the best position when shopping for coverage.

What insurance carriers evaluate

Insurance underwriting for homeowner's policies has become increasingly data-driven and property-specific. While each carrier's criteria vary, certain conditions consistently affect a property's insurability in San Diego County.

Roof condition and age

Roof condition is frequently the first item carriers evaluate. An aging roof with visible deterioration, missing materials, or an age that exceeds the carrier's threshold can result in nonrenewal, a requirement for replacement before renewal, or exclusion of roof-related coverage.

What to inspect: The roofing material type, its current condition, estimated remaining life, and whether any areas show active deterioration or damage. The age of the roof is often the simplest question a carrier asks, and having documentation of its condition (through an inspection report or a roof certification from a roofing professional) gives you something to present beyond just the age number.

Electrical panel type and condition

Certain electrical panel types create insurability challenges. Federal Pacific Electric (FPE) and Zinsco panels, both widely installed in San Diego homes during the 1960s and 1970s, have documented safety concerns. Some carriers may require replacement of these panels before issuing or renewing a policy.

What to inspect: The panel manufacturer, age, capacity, breaker condition, and any signs of overheating or previous problems. If the panel is an FPE or Zinsco, documenting its condition and having a plan for replacement (or having already replaced it) significantly improves your insurance positioning.

Plumbing condition

Plumbing failures (burst pipes, slow leaks, water heater failures) are among the most common and costly homeowner's insurance claims. Carriers increasingly evaluate the age and condition of the plumbing system, particularly the water heater, supply line material, and any history of water damage claims.

What to inspect: Supply pipe material (galvanized steel is a concern), water heater age and condition, visible signs of past leaks or water damage, and the overall condition of accessible plumbing. A home with a 20-year-old water heater, galvanized supply lines, and evidence of previous water damage presents a very different risk profile than a home with updated plumbing and no claim history.

Wildfire risk and defensible space

This is the factor driving the largest number of nonrenewals in San Diego County. Properties in Very High Fire Hazard Severity Zones face the most scrutiny, and carriers are increasingly requiring evidence of defensible space compliance and home hardening measures.

What to inspect: Defensible space conditions in all zones (Zone 0 within 5 feet, Zone 1 at 5 to 30 feet, Zone 2 at 30 to 100 feet). Roof material (Class A fire-rated is preferred). Vent screening (ember-resistant mesh). Eave and soffit construction (enclosed vs. open). Combustible materials stored against the structure. Fencing material attached to the home. And the overall condition of the building envelope.

Some carriers are now requesting photos of defensible space conditions as part of the renewal process. Having a documented inspection of your property's fire readiness, with photos showing compliance, provides the evidence carriers want to see.

Trees and vegetation

Overhanging branches, dead trees, and vegetation touching or close to the structure create both wildfire and wind-damage risk that carriers evaluate. Properties with large trees close to the roofline or power lines may face additional requirements.

What to inspect: The proximity of trees and large vegetation to the structure, roof, and power lines. Dead or dying trees on the property. Branch overhang above the roofline. And root systems that may be affecting the foundation or underground utilities.

Overall property condition

Beyond the specific items above, the general condition of the property affects insurability. Deferred maintenance visible from the exterior (deteriorated siding, damaged fencing, unmaintained walkways, standing water issues) signals higher risk to underwriters.

What to inspect: The exterior condition of the home overall. A well-maintained property with good drainage, intact exterior finishes, and no obvious deferred maintenance presents a lower risk profile than one showing visible neglect.

What you can do to improve insurability

Not every insurance challenge is about wildfire. Many of the conditions that cause nonrenewal or premium increases are addressable maintenance and improvement items.

Immediate impact improvements

Replace a known-risk electrical panel (FPE, Zinsco) with a modern panel. Replace a water heater that's past its expected service life. Clear Zone 0 (the five-foot perimeter around the structure) of all combustible materials. Clean gutters and remove roof debris. Trim branches away from the roofline and power lines. Install or verify smoke and carbon monoxide alarms.

Medium-term improvements

Address roof condition if the roofing material is nearing end of life. Repipe galvanized supply lines if they're creating water quality or pressure concerns. Install ember-resistant vent screening. Enclose open eaves. Replace combustible fencing within five feet of the structure with noncombustible materials.

Documentation improvements

Get a professional home inspection and keep the report. Get a roof certification if the roof is older but in serviceable condition. Take photos of defensible space compliance and keep them updated seasonally. Document any improvements you make (receipts, photos, permits).

Carriers respond to documented conditions. A homeowner who can present an inspection report showing a maintained property with a sound roof, updated electrical, functional plumbing, and defensible space compliance has a significantly stronger position than one who simply calls the carrier and asks for a quote.

How to use your inspection when shopping for insurance

If you're shopping for coverage (whether because of a nonrenewal or because you want better terms), the inspection report becomes a marketing document for your property.

Here's how to use it:

With your broker: Share the inspection report with your insurance broker. Highlight improvements you've made (new panel, cleared defensible space, new water heater). A broker who works with multiple carriers can match your property's documented condition against each carrier's underwriting criteria.

With the carrier directly: Some carriers allow you to submit property photos and inspection documentation during the application process. A home with a documented inspection showing good condition, updated systems, and defensible space compliance presents a lower risk profile than a home with no documentation.

After improvements: If you've made specific improvements to address a nonrenewal (replaced the panel, cleared Zone 0, addressed roof concerns), document the work with before-and-after photos, contractor invoices, and permits. Then reshop. The property that was nonrenewed six months ago may be insurable today with documented improvements.

For rate comparison: Multiple quotes from different carriers allow you to compare not just premiums but coverage terms, deductibles, and exclusions. The inspection report gives each carrier the same information to work from, which makes the quotes more comparable.

The San Diego-specific insurance picture

San Diego County's insurance challenges are driven by a combination of wildfire exposure, coastal risk, and the overall tightening of the California insurance market. Different parts of the county face different challenges:

Properties in Very High Fire Hazard Severity Zones (Poway, Ramona, Alpine, Scripps Ranch, Rancho Santa Fe, parts of Encinitas and Carlsbad) face the most significant wildfire-related underwriting scrutiny. Defensible space compliance and home hardening measures are increasingly required for coverage.

Coastal properties face erosion, flood, and coastal storm risks that some carriers evaluate separately from wildfire. Flood insurance (through the NFIP or a private carrier) is separate from homeowner's insurance and may be required in flood-prone areas.

Urban properties in lower-risk areas may face less severe challenges but are still affected by the market-wide premium increases and the overall reduction in carrier willingness to write new policies in California.

The California Department of Insurance's Sustainable Insurance Strategy is designed to bring carriers back into the market by allowing them to use forward-looking catastrophe models and account for real-world reinsurance costs, with the requirement that they also commit to writing policies in underserved areas. This is a work in progress, and its effects are beginning to show in early 2026 data, but the full impact will take time to materialize.

The FAIR Plan: when traditional insurance isn't available

If you've been nonrenewed and can't find coverage in the traditional market, the California FAIR Plan provides a backstop. The FAIR Plan is a state-mandated insurer of last resort that cannot refuse to insure a qualifying property regardless of its wildfire exposure.

However, the FAIR Plan has significant limitations. It provides fire-related coverage but does not include many of the perils covered by a comprehensive homeowner's policy (theft, liability, water damage, loss of use). To restore those coverages, you need to pair the FAIR Plan with a Difference in Conditions (DIC) policy from a separate carrier. The combined cost of FAIR Plan plus DIC is often higher than traditional comprehensive coverage.

The FAIR Plan is a temporary solution. The goal for most homeowners should be to make improvements that allow them to return to the traditional market, where coverage is more complete and competition between carriers can work in the homeowner's favor. The property improvements described above are the path back.

How a home inspection helps with insurance

A home inspection creates a documented record of your property's condition. For insurance purposes, this documentation serves several functions:

It identifies the conditions that carriers evaluate, so you know what to address. It provides photographic evidence of the property's current state, which can be shared with carriers during the application or renewal process. It establishes a baseline condition that can be referenced if you file a claim (demonstrating that damage was caused by a covered event, not a pre-existing condition). And it gives you a prioritized list of improvements that will have the most impact on your insurability.

We evaluate every component discussed in this article during our standard inspection: roof, electrical, plumbing, HVAC, foundation, exterior condition, grading and drainage, and (for properties in fire-prone areas) wildfire readiness including defensible space and building materials.

Frequently asked questions

Q: Why are San Diego homeowners losing insurance?

The primary drivers are wildfire risk exposure, increased reinsurance costs, large claim losses from recent California wildfires, and regulatory changes that are still being implemented. Properties in or near wildfire-prone areas face the most scrutiny, but the market contraction has affected homeowners across the county.

Q: What home conditions cause insurance nonrenewal?

Common conditions include aging roofs past the carrier's acceptable age, known-risk electrical panels (FPE, Zinsco), plumbing in poor condition, inadequate defensible space, combustible materials against the structure, deferred maintenance visible from the exterior, and location in a Very High Fire Hazard Severity Zone.

Q: Can a home inspection help me keep my insurance?

An inspection identifies the conditions that carriers evaluate, giving you a roadmap for improvements. Documented evidence of property condition and maintenance (inspection reports, photos, improvement receipts) strengthens your position during the underwriting process.

Q: What is the FAIR Plan?

The California FAIR Plan is a state-mandated insurer of last resort that provides basic fire coverage to homeowners who cannot find coverage in the traditional market. It does not provide comprehensive homeowner's coverage; additional perils (theft, liability, water damage) require a separate Difference in Conditions (DIC) policy.

Q: What improvements have the most impact on insurance?

Replacing a known-risk electrical panel, addressing roof condition, clearing defensible space (especially Zone 0), replacing an aging water heater, and maintaining the property's exterior condition are among the most impactful improvements for insurability. Each carrier's requirements vary, so check with your insurer or broker for specifics.

Q: Does defensible space affect insurance?

Yes. Many carriers now evaluate defensible space conditions, particularly in fire-prone areas. Some require photos of compliance as part of the renewal process. Zone 0 (the five-foot ember-resistant perimeter) and Zone 1 (5 to 30 feet) are the most commonly evaluated areas.

Q: How much has insurance gone up in San Diego?

Research from Stanford indicates that California homeowner premiums have risen 84% since end of 2020. The impact varies by location, property characteristics, and carrier. Properties in high-risk areas have seen the steepest increases. San Diego County's typical home value of approximately $928,000 means even moderate premium increases represent significant dollar amounts.

Q: What should I do if I get a nonrenewal notice?

Start shopping immediately. Contact independent insurance brokers who work with multiple carriers. Address any property conditions that may be causing the nonrenewal (roof, panel, defensible space). If the traditional market isn't available, the FAIR Plan plus a DIC policy provides a coverage backstop while you work on improvements to return to the traditional market.

Q: Does a roof certification help with insurance?

A roof certification from a licensed roofing professional documents the roof's current condition and estimated remaining useful life. For older roofs that are still in serviceable condition, a certification can help satisfy carrier requirements that might otherwise result in nonrenewal based solely on the roof's age.

Q: Is the California insurance market getting better?

There are early signs of improvement. The California Department of Insurance's Sustainable Insurance Strategy is beginning to bring some carriers back into the market, and the FAIR Plan's growth rate has slowed in early 2026. However, premiums remain significantly elevated, and homeowners in high-risk areas continue to face challenges. The situation is evolving.

Final thoughts

The insurance conversation has changed. It's no longer just about premium cost. For many San Diego homeowners, it's about whether they can get coverage at all. The conditions that determine insurability are largely the same conditions that determine a home's safety, resilience, and long-term maintenance needs. Addressing them isn't just about keeping your policy. It's about taking care of the property that represents the largest financial asset most families own.

An inspection gives you the data. The improvements give you the control. And the documentation gives you the evidence that carriers increasingly require. In a market where premiums have nearly doubled in five years and the insurer of last resort now covers one in twenty California homes, being proactive about your property's condition isn't optional. It's how you stay insured. Start with the inspection. Address what you can. Document everything. And shop the market with evidence, not hope.
