California FAIR Plan & Water Damage: Are You Covered?
If your homeowners insurance is a California FAIR Plan policy, a leaking ceiling may not be covered at all unless you also carry a second policy. Here's how that works, what the newly signed AB 1680 changes, and what to do if water damage happens now.
A standard California FAIR Plan policy doesn't cover water damage from leaks, burst pipes or appliances. To be covered, FAIR Plan homeowners have needed a separate Difference in Conditions (DIC) policy. AB 1680, signed September 27, 2026, pushes the FAIR Plan toward offering fuller homeowners coverage, but that won't change existing policies overnight. Check your declarations pages and ask your agent.

What the FAIR Plan is, and what it covers
The California FAIR Plan is the state's insurer of last resort, an association made up of the companies that sell property insurance in California. It exists so homeowners who can't find coverage on the regular market, usually because of wildfire risk, can still insure their homes.
A standard FAIR Plan dwelling policy is a named-perils policy built around fire. It covers a short list of causes of loss and leaves out much of what a typical homeowners policy includes, notably water damage, theft and personal liability.
| Coverage | Standard homeowners policy | FAIR Plan policy alone |
|---|---|---|
| Fire and smoke | Yes | Yes |
| Sudden water damage (burst pipe, failed hose) | Usually | No |
| Theft | Yes | No |
| Personal liability | Yes | No |
| Slow, long-term leaks | Usually excluded | No |
How a DIC policy fills the water damage gap
A Difference in Conditions policy is bought separately, from a different insurer, to pair with the FAIR Plan. Together, the two are meant to approximate a regular homeowners policy. For a ceiling leak, the DIC is the policy that would normally respond.
Things to check on your DIC before you need it:
- Does it cover sudden and accidental discharge from plumbing, appliances, AC and water heaters?
- What's the deductible for water losses? It may differ from the FAIR Plan's.
- Is there a separate limit for water damage or for mold?
- Does it include loss of use if the home isn't livable during repairs?
- How does it treat seepage and wear and tear?
Many FAIR Plan homeowners don't carry a DIC, often because of cost. If that's you, a ceiling leak is an out-of-pocket repair unless someone else's policy applies.
What AB 1680 changes in 2026
In February 2026, Insurance Commissioner Ricardo Lara and Assemblymember Lisa Calderon introduced AB 1680, the Make It FAIR Act. Governor Newsom signed it on September 27, 2026, along with AB 69 on FAIR Plan policy notices and renewals.
- Broader coverage. The law is aimed at having the FAIR Plan offer a more comprehensive homeowners option, closer to a standard policy, which would reduce the need for a separate DIC for water damage and liability.
- More oversight. It requires the FAIR Plan to act on the Insurance Commissioner's examination findings, and adds staffing, planning and transparency requirements.
- Not overnight. New coverage options have to be developed, filed and rolled out. Existing policies aren't changed retroactively.
The practical step for now: at your next renewal, ask your agent whether a broader FAIR Plan option is available yet, and compare it with keeping your DIC.
If your ceiling is leaking and you're on the FAIR Plan
- Stop the water and limit the damage. Shut off the supply, make wiring safe, and start drying. This is the cheapest part of the job whoever ends up paying.
- Find your policies. FAIR Plan declarations, any DIC, and for condos, your HO-6 and the HOA's master policy.
- Look at the source. If the water came from a neighbor's unit or a shared line, their policy or the association's may be the one that responds.
- Document it with photos, the timeline and the cause in writing, just as you would for any claim.
- Get a written estimate so you can decide between a claim and paying directly with real numbers.
The insurance claim help page covers the documentation to ask for, and the cost page explains what drives the price if you're paying directly.
Diamond Bar homeowners and the FAIR Plan
Diamond Bar sits against the Puente and Chino Hills and the Tonner Canyon open space, and some hillside and canyon-edge homes are in or near fire hazard severity zones. Those are the homes most likely to have been non-renewed and moved onto the FAIR Plan in recent years. If that happened to you, it's worth reading your current coverage with the same care you'd give a new policy, especially the water damage section.
FAIR Plan and water damage: questions
DIC policies, AB 1680 and what to do now.
Does the California FAIR Plan cover water damage?
A standard FAIR Plan dwelling policy doesn't cover water damage from leaks, burst pipes or appliance failures. It's built around fire and a short list of named perils. FAIR Plan homeowners have generally needed a separate Difference in Conditions (DIC) policy for water damage, theft and liability.
What is a DIC policy?
A Difference in Conditions policy, sometimes called a wrap-around policy, is a separate policy from another insurer designed to sit alongside a FAIR Plan policy and cover what it excludes. Depending on the policy, that can include water damage, theft, liability and loss of use. What it covers, and its limits and deductibles, vary a lot.
What does AB 1680 change?
AB 1680, the Make It FAIR Act, was signed on September 27, 2026. It strengthens state oversight of the FAIR Plan and moves it toward offering more comprehensive homeowners coverage, which could eventually include water damage. Changes like that take time to reach actual policies, and they don't apply retroactively. Ask your agent what's available for your renewal.
I only have a FAIR Plan policy and my ceiling is leaking. What can I do?
Stop the water and limit the damage right away; that's the cheapest step no matter what. Then check whether you have any other policy that might respond, such as a DIC, a condo HO-6 policy, or a neighbor's or HOA's policy if the water came from them. If none applies, get a clear written estimate so you can plan the repair and compare options.
Is a FAIR Plan common in Diamond Bar?
It's more common than it used to be. Statewide enrollment grew sharply as private insurers pulled back from wildfire-exposed areas, and homes near open space and fire hazard zones are the most likely to have been moved onto it. If you've been non-renewed in the last few years, check what your current coverage actually includes.
Does a DIC policy cover slow leaks?
Usually not, for the same reason standard homeowners policies don't: most exclude continuous or repeated seepage and wear and tear. A DIC is typically written to cover sudden, accidental water damage. Read its water damage and exclusion sections carefully.
