If you own property in California—a home, a rental, a storefront, even a vacant lot—you have a legal responsibility to keep it reasonably safe. That responsibility is called "premises liability."

Most people think of slip-and-fall lawsuits. But premises liability covers much more: swimming pool accidents, inadequate security, structural failures, and dog bites.

Here's what California property owners need to know about their legal duty—and how to protect themselves.

What Is "Duty of Care"?

In plain terms: you must act like a reasonably careful person would to prevent people from getting hurt on your property.

It's not a guarantee that no one will ever be injured. It's a requirement to take reasonable steps to identify and fix hazards.

Who Is on Your Property Matters

Your legal responsibility changes depending on why the person is there.

Invitee

Customers, tenants, clients—people there for business
Your duty: You owe invitees the highest duty of care. You must:
- Inspect the property for hidden or non-obvious dangers.
- Repair dangerous conditions you find.
- Warn them of any dangers that you haven't yet repaired.

Licensee

Social guests, friends, family
Your duty: Warn about hidden dangers you know about.

Trespassers

Someone with no right to be there
Your duty: Generally no duty, but you can't set traps.

Exception for children: California recognizes "attractive nuisance" doctrine. If you have something on your property that might attract children—a swimming pool, old machinery, a trampoline—you may owe a duty to keep it secured, even if the child is trespassing. Pool fencing laws are the most common example.

Wet floors without warning signs
Cracked sidewalks or uneven pavement
Poor lighting in stairwells or parking areas
Broken handrails or deteriorating stairs
Inadequate security in areas with known crime history
Unsecured swimming pools
Dog bites (California has strict liability—owners are responsible regardless of the dog's history)

How to Protect Yourself as a Property Owner

Inspect regularly. Walk your property looking for hazards. Do it routinely and document it.

Fix problems promptly. If you can't fix something immediately, put up a barrier or warning sign in the meantime.

Keep records. A log of inspections and repairs is your best evidence that you acted reasonably.

Follow local codes. Pool fencing, handrail height, smoke detectors—compliance matters.

Check your insurance. Make sure your liability coverage is adequate for your situation.

If Someone Is Injured on Your Property

Get them medical help if needed.
Document the scene. Take photos of the condition that caused the injury before anything changes.
Notify your insurance company.
Do not admit fault or make statements about liability.
Contact an attorney if the injured person retains one.

The Bottom Line

Your duty of care is ongoing. Regular inspections and prompt repairs reduce the risk of accidents—and create a strong defense if a claim is ever filed.

Whether you're a property owner facing a potential claim or someone injured by a hazardous condition, we're here to help you understand your options.
