Retail store safety California litigation almost always turns on the store's own inspection practices, not on the hazard itself. A puddle on a tile floor is not, by itself, evidence of negligence. The question a jury has to answer is how long the puddle was there and whether the store's inspection interval was reasonable given the level of foot traffic and the type of hazard involved. Every major retail chain maintains some version of a documented inspection or sweep log, whether paper-based or maintained through an electronic time-stamped system. These logs are discoverable, and they are frequently the single most important piece of evidence in the case, because they show, in the defendant's own words, what the company's internal policy required and whether employees actually followed it. Where a store cannot produce a sweep log for the specific date at issue, plaintiff's counsel can still establish the store's own internal standard through habit and custom evidence under Evidence Code section 1105, which allows evidence of an entity's habit or custom to prove conduct on a specific occasion.
