Illinois Rental Housing: Safe Drinking Water Standards Explained

Clean and safe drinking water is essential for all renters in Illinois. If you’re renting a house or apartment, both federal and state laws require your landlord to provide potable water that is free from health hazards. This guide explains what standards apply, what to do if you have water quality concerns, and where you can find official help.

Understanding Drinking Water Standards for Illinois Renters

Illinois law requires that landlords provide rental units that are safe, sanitary, and fit to live in, which includes access to safe drinking water. In most cases, rental properties receive water from a public water system regulated by the U.S. Environmental Protection Agency (EPA) and the Illinois Environmental Protection Agency (IEPA). These agencies enforce legal limits for contaminants such as lead, bacteria, and chemicals to ensure water is safe to drink.

Key Illinois Standards for Safe Water in Rentals

• Potable water must be provided to all tenants. This is required by the Illinois Forcible Entry and Detainer Act and the Illinois Lead Poisoning Prevention Act ^[1][2].
• Landlords are responsible for repairs if water supply pipes, fixtures, or the public system causes water contamination that makes it unsafe or unhealthy.
• Tenants can request water quality testing documentation from their landlord, especially in buildings constructed before 1986 due to higher risk of lead pipes.
• If your rental property relies on a private well, the landlord must maintain the well and ensure the water meets IEPA standards.

Who Regulates and Enforces These Standards?

The Illinois Environmental Protection Agency oversees drinking water safety for public systems. Tenant concerns about water quality in rental units are often handled at the municipal level, typically by your city or county’s housing or health department. Statewide, the Illinois Department of Human Rights and, in Chicago, the Chicago Department of Housing provide guidance on tenant rights. For residential disputes, the appropriate body is often a local circuit court, with legal guidance based on the Illinois Residential Tenants’ Right to Repair Act ^[3].

What Should Illinois Renters Do If Water Isn’t Safe?

If you notice unsafe drinking water—such as discoloration, unpleasant odor, or signs of contamination—you should:

• Promptly notify your landlord in writing about the issue.
• Request repairs or testing, and keep copies of all communications.
• If your landlord does not take corrective action, you may file a complaint with your local health or housing authority or, in some cases, seek repairs and deduct the cost from your rent (under certain legal requirements—see the section on forms and legislation below).

Important Forms Renters Should Know

• Notice to Landlord of Necessary Repairs (no official statewide form):
  Use a written letter or email to notify your landlord of water safety concerns. State the problem and request prompt repairs.
  Example: If you notice your tap water is brown, notify your landlord immediately, explaining the issue and requesting they investigate and make repairs.
• Demand for Repairs – City of Chicago: Residential Tenants’ Right to Repair and Deduct Form (Chicago Form):
  This form is used by Chicago renters if the landlord fails to make needed repairs after written notice. Tenants may, in qualifying cases, pay for repairs themselves and deduct costs from rent.
  Example: If the landlord does not fix a contaminated water supply after you’ve notified them, use this form to formally give notice and proceed with repairs under the law.

Always check with your local city or county housing office for required forms in your area.
