The duty usually follows control of the property
California's general negligence rule requires people to use ordinary care in managing property. If you were injured on property controlled by someone else, the first question is often who had the practical and legal ability to inspect, maintain, repair, warn about, or restrict access to the condition. The answer may involve an owner, commercial tenant, residential landlord, property manager, contractor, or more than one of them.
Ownership alone does not decide every case. A tenant may control the space where you were hurt, while an owner may retain responsibility for structural systems or common areas. A management company may have accepted inspection or repair duties. Agreements can help define those relationships, but actual control and conduct may also matter. Each potentially responsible party must be connected to the particular condition that caused your physical injury.
Notice can be actual or constructive
A claim often turns on whether the responsible person created the danger, actually knew about it, or should have discovered it through reasonable care. Constructive notice means the condition existed or recurred in a way that may have allowed a reasonable inspection to find it. The time needed to discover a hazard depends on the property, the activity, and the nature of the risk.
A dangerous condition is not limited to one type of event. It can involve a walking surface, stairway, fixture, access point, lighting problem, falling object, pool area, or security condition. Those subjects may have dedicated pages with more specific rules. On this broader page, the common question is whether control, notice, and a reasonable response connect the property condition to your injury.
Open or visible conditions still require a fact-specific analysis
An owner or occupier may argue that a condition was obvious and that you could have avoided it. Visibility can affect comparative fault and the scope of a warning duty, but it does not automatically end every claim. The analysis may consider why you were there, where your attention could reasonably be directed, lighting, crowding, the available route, and whether the condition created a foreseeable risk despite being visible.
Your legal status on the property and the reason for your presence may also matter. A customer, tenant, invited guest, worker, child, or passer-by can present different circumstances. California generally focuses on reasonable care rather than relying only on old labels. Permission to enter does not guarantee recovery, and an unexpected injury does not itself prove that the property was negligently maintained.
Public property follows a separate statutory path
If a city, county, state agency, school district, or another public entity controlled the property, ordinary premises concepts are not enough. Government Code § 835 generally requires proof of a dangerous condition, causation, a reasonably foreseeable risk, and either creation by a public employee or legally sufficient notice. Statutory immunities, including possible design-related defenses, may limit responsibility even when an injury occurred on public property.
A personal injury claim against a public entity generally must first be presented within six months under Government Code § 911.2. That claim-presentation step is different from filing a lawsuit. California generally provides two years for many other injury actions, subject to exceptions, but you should not rely on that longer period when a public entity may be involved. Insurance and contractual notice requirements can create additional timelines.
