In a California personal injury case where a customer slips on algae-covered concrete due to poor maintenance during the rainy season, the case likely falls under premises liability for negligence. This scenario presents a potentially strong claim for the injured party, especially if the business failed to inspect, clean, or warn about slippery surfaces during wet conditions.
⚖️ Legal Framework – Premises Liability (Civ. Code § 1714)
To recover damages, the injured person (plaintiff) must prove:
1. Duty of Care
- Property owners and businesses have a duty to maintain their premises in a reasonably safe condition.
- This includes anticipating and mitigating weather-related hazards, like algae growth on outdoor surfaces during the rainy season.
2. Breach of Duty
- Algae buildup on concrete is a known hazard—it becomes extremely slippery when wet.
- If the property owner:
- Failed to inspect the area regularly,
- Knew algae was likely to form during rainy months,
- Failed to pressure wash, clean, or treat the area, and
- Failed to post warning signs,
3. Notice – Actual or Constructive Knowledge
- Actual knowledge: The property owner or staff knew algae was present (e.g., complaints, inspections, visual observation).
- Constructive knowledge: The hazard existed long enough that they should have known and taken steps to fix or warn.
Given that algae buildup is seasonal and predictable, the business may have had constructive notice even without direct complaints.
4. Causation
- The plaintiff must prove that slipping on the algae caused their fall and resulting injuries.
- Photos of the surface, weather records, and witness statements help establish this.
5. Damages
- The plaintiff must show actual harm, such as:
- Medical expenses
- Lost income
- Pain and suffering
- Permanent disability or disfigurement (if applicable)
📎 Strong Evidence to Support the Claim
- Photos or video of the algae-covered area.
- Surveillance footage of the fall.
- Maintenance records (showing a lack of cleaning or inspections).
- Weather reports (proving rainy conditions).
- Witnesses who can confirm the condition of the walkway.
- Incident report and medical documentation.
⚠️ Comparative Negligence – California Rule
- California follows pure comparative negligence.
- If the customer is partially at fault (e.g., wearing inappropriate shoes or not paying attention), their damages are reduced by their share of fault.
Example: $80,000 in damages; customer is 25% at fault → recovery = $60,000
🕒 Statute of Limitations
- The plaintiff has 2 years from the date of injury to file a lawsuit (Cal. Code Civ. Proc. § 335.1).
- If the incident occurred on government-owned property, a government tort claim must be filed within 6 months.
✅ Summary
Slipping on algae-covered concrete during the rainy season may support a strong premises liability case if:
- The business failed to maintain outdoor surfaces in a safe condition,
- The algae hazard was foreseeable and preventable,
- There was no warning or signage, and
- The fall caused documented injuries.
