City sidewalk notice California litigation turns almost entirely on a single evidentiary question: did the public entity know, or should it have known, about the specific dangerous condition long enough before the injury to have fixed it. Without that showing, a claim against a municipality for a sidewalk defect fails regardless of how obviously hazardous the condition was on the day of the fall. This breakdown covers how referring attorneys and trial counsel build the notice record that Government Code section 835 requires.

Government Code section governing dangerous condition liability

Deadline to present a claim against a public entity
Government Code section 835 sets out two independent paths to liability against a public entity for a dangerous condition of public property: proof that a negligent act or omission by a public employee created the condition, or proof that the entity had actual or constructive notice of the condition under Government Code section 835.2 for a sufficient time before the injury to have taken protective measures. Sidewalk defect cases usually proceed under the notice theory rather than the creation theory, since sidewalks typically deteriorate gradually rather than being created dangerous by a specific act. Government Code section 830 defines a dangerous condition as one creating a substantial, rather than minor or trivial, risk of injury to a person using the property with due care in a reasonably foreseeable manner. That definition drives the trivial defect doctrine, under which California courts have found some minor sidewalk height differentials to be non-actionable as a matter of law.
Actual notice exists when the public entity had actual knowledge of the existence of the condition and knew or should have known of its dangerous character. The strongest actual notice evidence typically comes from prior complaints: 311 service requests, code enforcement referrals, prior claims filed against the city for the same location, or internal work orders showing the defect had already been flagged for repair. Public records requests for maintenance logs and complaint databases covering the specific block should go out immediately upon intake, since retention periods for these records vary by agency and can run out.
Constructive notice requires showing the condition existed long enough that the entity should have discovered it through a reasonable inspection system. Ask whether the city has a formal sidewalk inspection cycle, when this specific block was last inspected, and whether its own practices fell short of what a reasonable program would have caught.
Google Street View historical imagery, satellite photography, and neighborhood social media posts can sometimes establish how long a defect had visibly existed, corroborating a constructive notice theory even without a specific prior complaint.
Distinguishing a trivial defect from an actionable dangerous condition requires careful factual development around the size of the differential, lighting, foot traffic, and any aggravating circumstances such as debris or shadow that obscured the hazard.
Both paths satisfy Government Code 835, and a thorough case develops each one.

Refer a caseActual notice means the public entity had actual knowledge of the specific defect and its dangerous character, while constructive notice means the condition existed long enough that a reasonable inspection system should have discovered it.
There is no fixed number of days; courts look at the nature of the defect, the entity's inspection practices, and whether a reasonable inspection system operating with due care would have discovered the condition in time to correct it.
The trivial defect doctrine holds that minor, insignificant sidewalk height differentials do not create actionable liability even if a fall occurred, because Government Code section 830 requires a substantial risk of injury, not merely any imperfection.
