Selling a Vacant House in California: Risks, Costs, and Options
Every month a vacant house sits, it costs you $1,500-$4,000+ in taxes, insurance, utilities, and maintenance. Here's how to stop the drain.

In short
The largest risk in a vacant California house is not vandalism — it is that the insurance policy quietly stops covering it. Standard homeowner policies restrict or exclude coverage once a property has been vacant beyond a stated period, which is exactly the point at which claims become most likely.
Key takeaways
- Tell the carrier the property is vacant and get appropriate coverage; standard policies limit claims after a stated vacancy period.
- Keep utilities on. Water damage from freezing and mold from an unventilated house cost more than the utility bills.
- Removing an unauthorised occupant who has established residence generally requires a court process — self-help lockouts are unlawful in California.
- A seller who never lived in the property may be exempt from the standard disclosure form but still owes disclosure of known material facts.
- Defensible space, weed abatement, and HOA obligations do not pause because nobody lives there.

The Hidden Costs of Owning a Vacant House
A vacant California house costs $1,500-$4,000+ per month in carrying costs: property taxes ($400-$1,200/mo), insurance ($200-$500/mo — if you can get it; some carriers won't cover vacant properties), utilities to prevent pipe freezing and maintain security systems ($150-$300/mo), yard maintenance ($200-$500/mo), and security monitoring ($50-$100/mo). Over 6 months, that's $9,000-$24,000 consumed by a property generating zero income.
Vacant properties also face specific risks: vandalism, squatter occupation (which creates legal complications for removal under California law), pipe bursts from lack of climate control, pest infestation, and the general accelerated deterioration that comes from a home without occupants monitoring and maintaining it.
Why Vacant Properties Need Cash Buyers
Traditional listing of a vacant home requires ongoing carrying costs during the 3-6 month marketing period, plus the risk that the home's condition deteriorates while sitting empty. Staging a vacant home adds $3,000-$8,000 in cost. Insurance complications on vacant properties (many carriers require occupied-dwelling policies) add another barrier.
A cash sale stops the financial bleeding immediately. Close in 10-14 days, end all carrying costs, eliminate the deterioration and security risks, and convert the non-performing asset into liquid capital.
The insurance gap that catches almost everyone
Homeowner policies are written on the assumption that someone lives in the house. Most contain a provision limiting or excluding coverage once the property has been vacant beyond a stated period — often measured in weeks, not months. The result is a property that is nominally insured and practically not, precisely during the period when an unnoticed leak, a break-in, or a fire is most likely.
The fix is unglamorous: tell the carrier the property is vacant and ask what coverage applies. Vacant property policies exist, they cost more, and they are worth it. This matters most for inherited houses and properties awaiting sale, where months pass while a family or an estate decides and nobody thinks to call the insurer.
Do not turn everything off
The instinct to shut off utilities to save money is understandable and frequently expensive. Without heat, plumbing freezes and bursts; without ventilation, moisture accumulates and mold follows; without power, alarms and sump pumps do nothing. Meanwhile inspectors, appraisers, and buyers cannot properly assess a house with no working systems, which slows a sale and invites conservative assumptions.
Where a property will sit through a cold season, winterising properly — rather than simply switching things off — is the right answer, and it is worth asking the carrier what they require. Some coverage depends on the property being maintained in a particular way.
Occupants who should not be there
If someone has moved into a vacant property, the response has to go through the courts. California prohibits self-help remedies — changing locks, removing belongings, cutting utilities — and the penalties for doing so are set by statute. Whether the situation is handled as a trespass or requires an unlawful detainer depends on the facts and on whether residency has been established, which is a question for an attorney and, in the first instance, for law enforcement.
The prevention is presence: someone checking the property, mail collected, the yard maintained, and the house visibly cared for. Most unauthorised occupation happens at properties that plainly nobody is watching.
Common mistakes
Leaving the existing policy in place after the house empties.
Instead: Tell the carrier about the vacancy and get suitable coverage. Standard policies restrict exactly the claims a vacant house generates.
Shutting off power and water to save money.
Instead: Freeze damage and mold cost far more than the utilities. Winterise properly and ask the carrier what they require.
Changing the locks on an unauthorised occupant.
Instead: Self-help is unlawful in California and carries statutory penalties. Go through law enforcement and the courts.
Assuming that never having lived there removes the duty to disclose.
Instead: Some fiduciary transfers are exempt from the standard disclosure form, but known material facts must still be disclosed.
Frequently asked questions
Can you buy a house that's been vacant for years?
Yes. We buy homes that have been vacant for any duration — months or years. Deterioration from vacancy affects our offer but never our willingness to purchase.
What about squatters?
We can purchase properties with squatter situations and handle the legal process for removal after closing according to California law.
Does my homeowner's insurance cover a vacant house?
Usually not fully. Most standard policies limit or exclude coverage once a property has been vacant beyond a stated period. Notify the carrier and obtain vacant property coverage — it costs more, and it is what actually responds when something happens to an empty house.
Should I turn off the utilities?
Generally no. Heat prevents frozen pipes, ventilation limits mold, and working systems let inspectors and appraisers do their jobs. If the property will be empty through winter, winterise it properly rather than simply shutting it down, and confirm what your carrier requires.
Someone is living in my vacant house. What can I do?
Contact law enforcement first, and an attorney. California prohibits self-help removal — changing locks, removing property, or cutting utilities — and imposes penalties for it. Whether the matter proceeds as a trespass or requires an unlawful detainer depends on the facts.
Do I have to complete a disclosure form if I never lived in the house?
Some transfers — for example by certain fiduciaries such as an executor or trustee who has never occupied the property — are exempt from the standard Transfer Disclosure Statement. That exemption does not remove the general obligation to disclose known material facts affecting value or desirability.
Bottom line
Call the insurer the week the house empties, leave the utilities on, and have someone physically check the property. Those three things prevent most of what actually goes wrong with a vacant California house — and all three are cheaper than the claims that a vacancy exclusion will not pay. Not legal advice.
