Why You Need a Proposition 65 Warning Notice (Safe Drinking Water and Toxic Enforcement Act)
The Proposition 65 Warning Notice is a mandated federal/state environmental compliance document required under California's Health and Safety Code, Division 20, Chapter 6.6 (commonly known as Proposition 65) and by the U.S. Environmental Protection Agency (EPA) through delegated programs. For San Jose restaurants, this is enforced locally by the California Environmental Protection Agency (CalEPA) and the Santa Clara County Department of Environmental Health. It demonstrates that you have been notified of a potential environmental release, typically involving chemicals like lead, arsenic, or benzene that are on the state's Proposition 65 list and require public warning. This notice is a prerequisite for operating in compliance with both state right-to-know laws and federal programs for water, air, and hazardous waste management that the state administers.
Failure to properly file and post the required Proposition 65 Warning Notice carries significant legal and operational risks for your restaurant. The consequences include:
- Civil penalties of up to $2,500 per day per violation from CalEPA and the California Attorney General's office for failure to warn.
- Third-party lawsuits from private enforcers, which can result in additional penalties and settlement costs that often reach tens of thousands of dollars.
- Exposure to criminal prosecution under federal statutes like the Clean Water Act or RCRA if the underlying violation involves hazardous substance release.
- Consent orders and mandatory cleanup liability requiring expensive environmental remediation and ongoing monitoring.
- Lease and insurance implications, as landlords and insurers may terminate agreements due to non-compliance with environmental laws.

Recent update: As of 2025, California updated its Proposition 65 warning language requirements for food and beverage exposures, and enforcement actions in Santa Clara County have specifically targeted restaurants for not using the new, clearer warnings regarding carcinogens and reproductive toxins.
Who Needs a Proposition 65 Warning Notice (Safe Drinking Water and Toxic Enforcement Act)?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required because establishments serving food and beverages likely expose customers to listed chemicals, such as acrylamide from cooked foods or mercury in certain seafood, exceeding the state's Safe Harbor Levels. |
| Bar / Nightclub | Required | Required because alcoholic beverages are a known source of Proposition 65 listed chemicals, such as alcohol (ethanol) and acetaldehyde, requiring a warning for on-site consumption. |
| Food Truck | Required | Required because mobile food facilities serve prepared food, often through frying or grilling, which can expose customers to listed chemicals like acrylamide, triggering the warning requirement. |
| Coffee Shop / Café | Required | Required because coffee naturally contains acrylamide, a Proposition 65 listed chemical, and the brewing/serving process constitutes an exposure requiring a clear and reasonable warning. |

1. Using Generic Warnings Without Specific Chemical Names
Posting a general Prop 65 warning sign that does not list at least one specific chemical (e.g., lead, acrylamide, mercury) present at your facility. This fails the 'clear and reasonable' requirement, leaving you non-compliant and vulnerable to 60-day 'Notice to Violate' letters from private enforcers, which can lead to costly settlements. Always consult your chemical inventory, Safety Data Sheets (SDS), or conduct a compliance review to identify the specific chemical of concern triggering the warning requirement for your restaurant (e.g., 'WARNING: This area contains lead, a chemical known to the State of California to cause birth defects or other reproductive harm.').
2. Improper Warning Placement & Sizing
Placing the warning sign in a low-traffic employee-only area or using font sizes smaller than the mandated minimums. Warnings must be 'reasonably calculated' to be seen before exposure, typically at each public entrance and in areas where the chemical is present (e.g., near the bar if alcohol is served). Signs with text smaller than the required type size (often 12-point or larger) are a common defect cited in enforcement actions. Measure your sign and ensure it is posted prominently where customers and employees can see it before entering or being in the affected area.
3. Failing to Update Warnings for Menu Changes
Not reviewing and updating warning notices when your menu changes to include new items known to contain listed chemicals (e.g., adding fried potatoes or coffee, which can expose acrylamide). Your initial compliance isn't a one-time task; the law requires warnings for current exposures. A failure to update can result in enforcement based on your new menu items, potentially restarting the 60-day notice period for a new violation and leading to separate penalties. Conduct an annual review of your menu and any new products against the updated Prop 65 chemical list published by OEHHA.

Determine If a Warning is Required for Your Water
First, review the California Office of Environmental Health Hazard Assessment (OEHHA) list of regulated chemicals and safe harbor levels. You must conduct or obtain a water quality analysis for chemicals like arsenic or lead that may be present in your drinking water. Compare your results to the 'No Significant Risk Levels' — if levels exceed these limits, a warning is required. This initial testing is the most time-consuming phase, often taking several weeks to schedule and receive certified lab results.
Draft the Compliant Warning Text
Using the OEHHA's 'Safe Harbor' warning language, draft your notice. For drinking water, the warning must clearly name at least one chemical (e.g., arsenic) that is present and state it can cause cancer or reproductive harm. The text must be in at least 6-point font and use the word "WARNING" in all caps. Many businesses fail by using generic signs or omitting the specific chemical name, which violates the law. ApronPrep's template library includes OEHHA-compliant language tailored to water exposure scenarios.
Post the Warning at Points of Exposure
You must ensure the warning is provided to individuals before exposure. For drinking water in a restaurant, this means posting the notice in a conspicuous location where customers are served water or where they fill cups (e.g., near water stations, on menus, at host stands). You must also consider employee exposure areas. The California Attorney General's enforcement guidelines state that warnings must be "clear and reasonable" — inadequate posting is a common basis for lawsuits, which can result in penalties of up to $2,500 per day per violation.

See All RequirementsThere is no standard processing time for this requirement, as it is based on your facility's compliance status. You must post warnings immediately upon determining an exposure to a listed chemical occurs. Timelines are dictated by your ability to conduct the necessary hazard assessment and implement signage, not by a government approval period. Contact the Office of Environmental Health Hazard Assessment (OEHHA) to confirm specific deadlines for your business.
There are no government filing fees charged by the state for the Proposition 65 warning requirement itself. Your costs are for producing and posting compliant signage and potentially for the required Building Permit if signage installation involves structural modifications. Legal liability arises from non-compliance, including potential civil penalties of up to $2,500 per day per violation, as stated in Health and Safety Code § 25249.7.
No, warnings are not transferable permits. They are based on the specific operations, chemicals, and exposure risks at a given physical location. If you move your restaurant, you must conduct a new hazard assessment for the new premises and post updated warnings based on that site's conditions. This requirement operates independently of other licenses, such as an California Liquor License (On-Premises), which also requires a separate application for a new address.
There is no formal renewal process. The warning is an ongoing obligation. You must review and update your warnings whenever there is a change in your operations, chemicals used, or the state's list of regulated substances (updated at least annually). Failure to maintain current warnings can trigger enforcement actions. Regular review should be part of your operational checklist, similar to maintaining your Backflow Prevention Device Certification.
Enforcement inspections are typically complaint-driven and conducted by the California Attorney General's office, local prosecutors, or private enforcers. They will verify that required warnings are posted conspicuously where exposures occur (e.g., entrances, points of sale) and that the warning language meets OEHHA regulations. Inspectors may also request documentation of your hazard assessment to prove you have evaluated potential exposures from chemicals in food, alcoholic beverages, or environmental contaminants like tobacco smoke.
