Homeowners Insurance in San Diego: What Buyers Should Budget For in 2026
The short answer
Homeowners insurance has become one of the biggest wildcards for San Diego buyers. California's market is tight, more homeowners are relying on the California FAIR Plan, and the FAIR Plan's approved 29.1% rate increase takes effect October 15, 2026. Buyers should get insurance quotes as soon as they're under contract (ideally before), budget for the full annual premium, and understand that some homes may need more than one policy.
The purchase price is only the beginning
I'm Peter Seroter, an independent mortgage broker with 25 years of experience, licensed in Arizona and California. I live in North Phoenix and spend a lot of time in San Diego visiting my brother.
Here's a lesson I learned when I bought my SunTracker pontoon: the sticker price is just the start. Insurance, storage, registration, maintenance, and fuel all come after. If you only budget for the boat, the boat ends up owning you.
Homes work the same way, and in San Diego right now, insurance is the line item that catches buyers off guard most often. I've seen deals get tense in escrow because a buyer assumed insurance would be a quick phone call. In today's California market, it isn't always.
What's going on with California homeowners insurance?
After years of catastrophic wildfires, several insurers pulled back from writing new policies in higher-risk parts of California. That pushed more homeowners toward the California FAIR Plan, the state's insurer of last resort.
FAIR Plan enrollment rose about 43% between September 2024 and December 2025.
The FAIR Plan has been approved for a 29.1% rate increase beginning October 15, 2026, mainly affecting high-risk, fire-prone areas. It originally requested a larger increase.
The California Department of Insurance now allows insurers to factor climate risk into pricing, which could mean more rate changes ahead.
State officials and lawmakers are pursuing changes aimed at stabilizing the market and encouraging private insurers to return to higher-risk areas.
San Diego County has a mix of coastal, urban, and inland areas, and insurance availability and cost can vary a lot depending on where a home sits and its wildfire exposure.
Why the FAIR Plan might not be enough on its own
The FAIR Plan generally provides fire-focused coverage, not a full homeowners policy. Homeowners who rely on it often add a separate "difference in conditions" (DIC) policy to cover other risks like theft, water damage, and liability.
That means two policies, two premiums, and two sets of paperwork. When you're comparing homes, factor that possibility into your budget.
Why insurance matters to your mortgage
Your lender requires proof of adequate homeowners insurance before closing. That affects you in two ways:
1. It's part of your qualifying payment
Insurance is included in your total housing payment when your debt-to-income ratio is calculated. A higher premium can reduce how much home you qualify for. That's why I want a real quote, not a guess, as early as possible.
2. It can affect your closing timeline
If coverage is hard to place on a specific property, it can delay closing. Starting early protects your contract dates.
How San Diego buyers should approach insurance
Get quotes before you write an offer on a home you're serious about, especially if it's in or near a wildfire-exposed area.
Use an independent insurance agent who can shop multiple carriers, including the FAIR Plan and DIC options if needed.
Ask about mitigation discounts. Home hardening such as fire-resistant roofing, ember-resistant vents, and defensible space can help with eligibility or pricing.
Check the claims history on the property if possible. Prior claims can affect what's available.
Budget for the full year upfront. Your first-year premium is typically paid at or before closing.
Re-shop at renewal. The market is changing quickly, so the best option this year may not be the best next year.

San Diego homeowners insurance FAQs
Why is homeowners insurance so hard to get in California?
Wildfire losses led several insurers to limit new policies in higher-risk areas. That has pushed more homeowners toward the FAIR Plan and raised costs in many places.
What is the California FAIR Plan?
It's the state's insurer of last resort, designed for homeowners who can't find coverage in the regular market. It generally covers fire, so many owners pair it with a DIC policy.
When does the FAIR Plan rate increase take effect?
The approved 29.1% increase begins October 15, 2026, and mainly affects homes in high-risk, fire-prone areas.
Does insurance affect how much house I can afford?
Yes. Insurance is part of your monthly housing cost used to calculate your debt-to-income ratio, so a higher premium can lower your buying power.
