California Renters: Safe Drinking Water Standards Explained

Every renter deserves safe, clean drinking water at home. In California, laws protect tenants by setting minimum standards for water quality in rental properties. Understanding these requirements helps renters advocate for a healthier living environment and know when to seek help from official agencies.

What Are the Drinking Water Standards for Rental Properties?

California law requires all rental units to provide safe and potable (drinkable) water. This forms part of a landlord’s responsibility to maintain a rental property that meets basic health and safety standards.

• Potable Water: The rental unit must always have access to water that is safe to drink, cook with, and use for bathing.
• Plumbing Systems: Landlords must ensure that pipes, plumbing, and fixtures deliver water free from unsafe contaminants such as lead, bacteria, or dangerous chemicals.

These protections are part of California’s statewide implied warranty of habitability under the California Civil Code^[1].

Who Regulates Drinking Water Quality?

Drinking water safety is overseen by state and local agencies, including the California State Water Resources Control Board and your city or county health department. These agencies enforce water standards and investigate complaints about water quality in rental housing.

Your Landlord’s Responsibilities

• Promptly repair leaks or broken fixtures affecting water supply.
• Address reports of dirty, discolored, or foul-smelling water.
• Comply with all local and state water quality health codes.
• Respond to written requests about suspected water contamination.

Landlords cannot avoid or reduce their legal responsibility to deliver safe, potable water in rental units—this requirement cannot be waived in a lease agreement.

What Should You Do if You Suspect Unsafe Drinking Water?

If your tap water seems unsafe—due to color, odor, taste, or after receiving a public health notice—there are important steps you can take.

• Notify your landlord in writing about the issue. Clearly describe the water problem and request a fix.
• If your landlord does not respond promptly (within a reasonable time, often 30 days or less depending on urgency), you may file a health or code complaint.
• For urgent hazards (dangerous contamination), local health departments may intervene directly.

Official Complaint Forms and Process

• Request for Inspection (Form): Many local health departments offer a form to request an inspection of your rental for health and safety violations, including water quality.
  • When to use: If your landlord does not fix a reported water problem, submit this form to your city or county health department. For example, if your tap water is brown, and your landlord ignores your written request, you can formally ask the health department to inspect.
  • How to use: Visit your local or county health department website and search for "rental housing complaint" or "code enforcement inspection." Some cities, like Los Angeles, provide online reporting portals. If unavailable, you may call or visit in person.
• State Water Board Complaint Form: For suspected contamination by a public water system, file a complaint using the Drinking Water Program Complaint Form (no number).
  • This is most useful if the issue involves a broader water system serving multiple homes, not just your unit.

Name of Tribunal Handling Complaints

For unresolved habitability disputes, including water quality, renters may seek recourse through local housing code enforcement or the courts. In California, tenant–landlord dispute cases may be heard at your local Superior Court – Housing Division (if available) or Small Claims Court^[2].

Relevant California Law

• California Civil Code Section 1941.1 requires landlords to supply potable water and maintain pipes and fixtures in good working order. Read more in the California Civil Code – Housing and Rental Standards.
• California Health and Safety Code sets statewide public health standards for water quality; local ordinances may provide added protections.

FAQ: Safe Drinking Water in California Rentals

1. What should I do if my tap water is discolored or has an odd smell?
   You should immediately notify your landlord in writing. If the issue is not fixed quickly, you can contact your local health department to request an inspection, or file a complaint with the State Water Board if you suspect contamination from a public water system.
2. Is the landlord required to provide bottled water if the tap water is unsafe?
   If the tap water is unsafe, the landlord must provide a safe alternative (which may include bottled water) until repairs or corrections are made to restore safe tap water.
3. How quickly does the landlord have to fix water quality issues?
   Landlords must address threats to health and safety as quickly as possible—urgent hazards may require same-day or immediate action. Otherwise, repairs should be made within a reasonable timeframe (often up to 30 days), depending on severity.
4. What are my rights if my landlord refuses to fix unsafe water?
   You can file a complaint with your local health/code enforcement and, if necessary, take legal action in your local housing or small claims court to enforce habitability standards.
5. Are there official forms I should use to complain about water quality?
   Yes, local health departments provide rental housing complaint forms. You can also use the State Water Board’s Drinking Water Program Complaint Form for public water supply issues. Always save copies for your records.

Conclusion: Know Your Rights and Next Steps

• California law requires all rental properties to provide safe, drinkable water at all times.
