Some of the most expensive mistakes in this area are not decisions. They are assumptions that were never examined, usually inherited from an era when insurance was a formality on a California purchase. Five of them come up often enough to be worth naming.
This article extends the insurance guide. It is written by a real estate professional, not an insurance broker or an adjuster. Nothing here describes what any policy covers or what any carrier will do. Every specific belongs to a licensed insurance professional, to the carrier in writing, and where a consumer question arises, to the California Department of Insurance.
Myth one: insurance is a formality you handle near closing
This was true for a long time and it is the single most costly leftover belief. In the current California market the binding constraint is AVAILABILITY rather than price, and availability takes time to establish: multiple carriers, questions about the property, sometimes an inspection, sometimes documentation the buyer has to go and find.
The replacement habit is simple. Shop the day escrow opens, with the address in hand. If placement is going to be a problem, that fact is worth having while the inspection period is open and the ordinary negotiating machinery is available. The sequence is in the article on binding coverage in escrow.
Myth two: my coverage should equal what my house is worth
Market value includes the land, and the land does not burn. The dwelling limit is an estimate of what it would cost to REBUILD the structure, which is a construction question involving current labor and materials, site access, finish level and the code in force at the time of the rebuild.
The replacement habit is to ask a licensed broker what property characteristics the estimate was built from, check those against the actual house, and report improvements the carrier has never been told about. The reasoning is in the article on setting dwelling coverage.
Myth three: I have full coverage
There is no such product. A homeowners policy is a specific contract with specific coverage sections, specific limits, one or more deductibles, and a list of endorsements that add and subtract. Certain categories of loss are addressed by entirely separate coverages that most owners do not automatically have.
The replacement habit is to read the declarations page once a year and ask a licensed broker to translate the endorsement list into plain sentences. It takes minutes, and the method is set out in the article on reading a declarations page.
Myth four: a small claim is free
Loss history follows the PROPERTY, is visible to future carriers, and can shape later placement and renewal outcomes. That does not mean real damage should go unreported, and it does not mean owners should absorb serious losses to protect a record. It means the choice deserves to be a decision rather than a reflex, made with a licensed broker who understands the specific policy and the specific circumstance.
The replacement habit is to request and read the property's own loss history, so the record is a known quantity rather than a surprise during a placement. The mechanics are in the article on the CLUE report.
Myth five: a non-renewal means the house is uninsurable
A notice from one carrier is one company's decision under one set of guidelines. Different carriers use different models, different thresholds and different appetites, and the practical response is breadth of shopping through a broker with access to multiple markets, alongside addressing whatever the notice named.
Two cautions, both important. The rules governing these notices, the timelines involved and the availability of any backstop are set by California law and regulation, they are revised, and they are exactly the kind of specific that goes stale in writing. VERIFY THE CURRENT POSITION with a licensed broker and the California Department of Insurance rather than relying on any description, including this one. And nobody can promise an outcome for a specific property. What the options look like in structure is set out in the article on non-renewal options.
Why these five survive
Each one was true, or true enough, within living memory. Insurance really was a formality on a California purchase. Coverage really did get discussed as a single number. Policies really were more uniform. Claims really were less consequential to a record nobody consulted. And a carrier declining a house really was unusual enough to feel like a verdict.
Beliefs formed in a market do not update when the market does. They get passed along by people who were right the last time they said them, which is what makes them durable and what makes them worth naming explicitly rather than assuming everyone has noticed.
The habit underneath all five
Every one of these myths is a substitute for asking. The general lesson across this whole cluster is that the useful behaviors are unglamorous and cheap: start early, document what exists, read the page that summarizes the contract, report what changes, and put the specific question to the person licensed to answer it. None of that requires expertise. It requires doing the thing before the deadline rather than after it.
The takeaway
Insurance is not a formality, coverage is not market value, no policy is total, a claim is a decision, and one carrier is not the market. Take all five of those to a licensed insurance professional with your own address and your own policy in hand, get the answers in writing from the carrier, and raise consumer questions with the California Department of Insurance.

Frequently asked questions
When should I start shopping for home insurance on a purchase?
The day escrow opens. In the current California market availability rather than price is the binding constraint, and establishing whether a property can be written takes time. Late shopping converts a solvable problem into a closing crisis.
Should my coverage equal my home's value?
No. Market value includes the land, which cannot burn. The dwelling limit estimates the cost to rebuild the structure at current labor and materials, to current code, with the site and finish level factored in.
Is there such a thing as full coverage?
No. A homeowners policy is a specific contract with defined coverage sections, limits, deductibles and endorsements, and several categories of loss are addressed by separate coverages entirely. Ask your licensed broker to translate your own endorsement list.
Does filing a small claim really matter?
Loss history follows the property and is visible to future carriers, so a claim is a decision worth making deliberately with a licensed broker. That is not an argument for absorbing serious losses or leaving real damage unreported.
Does a non-renewal mean my home cannot be insured?
It is one carrier's decision under one set of guidelines, and different carriers use different models and thresholds. The rules and timelines governing these notices are set by California law and change, so verify the current position with a licensed broker and the Department of Insurance.
