Can Your Water Be Shut Off in California for an Unpaid Bill?

Updated 2026-08-31 · Plumber Comparator editorial team

A hidden leak runs for two billing cycles, the bill arrives at four figures, and suddenly a plumbing problem has become a household finance problem. What happens next is governed by a state law most Californians have never heard of — the Water Shutoff Protection Act, Health and Safety Code sections 116900 through 116926 — and it gives you considerably more room than a shutoff notice implies. Here's what it actually requires.

It now covers essentially every water system in the state

The Act originally applied only to systems with more than 200 service connections, and a lot of online summaries still say that. It's out of date. SB 3 (2023) extended the Act to all community water systems — meaning any system with at least 15 service connections or that regularly serves at least 25 year-round residents — with compliance for the newly covered small systems taking effect August 1, 2024. If you get a bill from a water system in California, assume the Act applies. The only exemption in the chapter is a disconnection due to an unauthorized action by the customer, such as tampering.

One important limit: the Act applies to residential water service. It does not cover sewer or wastewater charges, a point the Attorney General's 2024 legal alert states explicitly. Where an agency bills water and sewer together, the delinquency that starts the clock may include sewer charges, and agencies keep separate remedies for sewer debt that this law doesn't touch.

The steps a water system has to take before shutting you off

• 60 days minimum. Section 116908 prohibits discontinuing residential service until a payment has been delinquent for at least 60 days. A shutoff threat on a bill that's three weeks late is not a lawful shutoff.
• Contact at least seven business days ahead. The system must reach the customer named on the account by telephone or written notice no fewer than seven business days before discontinuation.
• The notice has required contents: your name and address, the amount of the delinquency, the date by which payment or an arrangement is required, how to apply for an extension, how to petition for bill review and appeal, and how to request a deferred, reduced, amortized or alternative payment schedule. If the contact is by phone, the system must offer the written policy and discuss those options.
• If mail comes back undeliverable and phone contact failed, the system must make a good-faith effort to visit the residence and leave a notice of imminent discontinuation. If your mailing address differs from the service address, notice also goes to the property addressed to "Occupant."
• No shutoff while an appeal is pending. If an adult at the residence has filed an appeal of the bill, service cannot be discontinued while it's being decided. This is the single most useful sentence in the statute for someone facing a leak-inflated bill they intend to dispute.

Payment plans are now open to everyone

Section 116906 requires every covered system to maintain a written discontinuation policy containing a deferred or reduced payment plan, alternative payment schedules, a formal mechanism to contest or appeal a bill, and a phone number to discuss options. The 2023 amendments made an important change: those payment options must be available to any customer unable to pay, not only to customers who meet medical and financial criteria.

The policy has to be posted on the system's website if it has one, and provided in Spanish, Chinese, Tagalog, Vietnamese and Korean by systems with more than 200 connections, plus any language spoken by at least 10% of residents in the service area. If you can't find it, ask for it in writing — the obligation to have it is not optional.

The medical protection, and its three conditions

Section 116910 bars a shutoff when all three of these are true:

1. A primary care provider certifies that discontinuation would be life-threatening to, or a serious threat to the health and safety of, a resident of the premises;
2. The customer demonstrates inability to pay within the normal billing cycle — either by receiving CalWORKs, CalFresh, Medi-Cal, SSI/SSP, WIC or general assistance, or by household income below 200% of the federal poverty level;
3. The customer is willing to enter an amortization agreement, alternative payment schedule, or deferred or reduced payment plan.

Where that applies, the system must offer at least one repayment route, ordinarily structured to clear the balance within about 12 months, extendable to avoid undue hardship. A shutoff can then happen only five business days after a posted final notice, and only if the customer misses the plan or current charges by 60 days or more.

Reconnection fees are capped — for some households

Section 116914 caps the reconnection fee at $50 during normal operating hours and $150 during non-operational hours — but not more than the actual cost of reconnection if that's lower — with an annual CPI adjustment that began January 1, 2021. Read the eligibility limit carefully: those caps apply only to households below 200% of the federal poverty line or receiving the assistance programs listed above. There is no statutory cap for everyone else. Qualifying customers are also entitled to have interest on the delinquent bill waived once every 12 months, and self-declaration of income is sufficient.

Because agencies do their own CPI math and no state agency publishes an official adjusted schedule, the current figure varies by utility — the State Water Board's own FAQ still prints the flat $50 and $150. Ask your utility what it charges; some are well under the cap regardless (San Jose Water, for example, charges $20 in business hours and $30 after).

If you rent

Section 116916 covers the case where the landlord is the customer of record and the tenants are the ones about to lose water. The system must give written notice at least 10 days before terminating (7 days for a detached single-family dwelling) telling occupants they may become customers without paying the landlord's delinquent balance. Occupants have to meet the service terms, but proof of residence and prompt rent payment can substitute for a prior service history. And occupants whose rent includes water may deduct the reasonable charges they pay the water system from their rent. Our guide to landlord and tenant plumbing responsibilities covers the repair side of that relationship.

The assistance gap nobody advertises

The federal Low Income Household Water Assistance Program — the water equivalent of energy bill assistance — sunset on March 31, 2024, after distributing roughly $116 million in one-time funding in California. As of today there is no active statewide low-income water bill assistance program. What remains is utility-by-utility: lifeline rates, hardship funds and payment plans that vary enormously between agencies. If you're in trouble on a water bill, the phone call is to your own utility, and the ask is a payment plan under section 116906.

Why this is a plumbing article, not just a billing one

Because in most cases the honest fix for an unpayable water bill is finding the leak. Water affordability is a real and worsening pressure in California — a 2020 study by Teodoro and Saywitz in AWWA Water Science found low-income households spending an average of 12.4% of disposable income on water and sewer service, up from 10.9% (study on Google Scholar). And the stakes of a shutoff are not just inconvenience: a 2022 study by Zhang, Warner and Grant in the American Journal of Preventive Medicine found that state water shutoff moratoria measurably lowered COVID-19 infection and death growth rates, with the strongest effect where moratoria covered both public and private systems (study on Google Scholar). Running water is a public health input, which is why the protections above exist at all.

What to do this week if a bill has spiked

1. Check for a leak before you argue about the amount. Read the meter overnight with no water running, and dye-test every toilet. Our guides to reading your water meter and diagnosing a high water bill walk through it.
2. File the appeal in writing if the bill looks wrong. Service can't be discontinued while it's pending.
3. Ask for a payment plan under section 116906 in the same message. It's available to any customer who can't pay, not only to low-income households.
4. Fix the leak and keep the invoice — many California utilities will credit part of a leak-inflated bill, but only if you apply in time and can prove the repair. Deadlines range from 15 days to three years depending on the agency; our guide to water bill leak adjustments lists the real ones. With rates rising across the state, as our guide to 2026 water and sewer rate increases covers, that credit is worth more than it used to be.

If the meter keeps moving after you've ruled out toilets and fixtures, the leak is somewhere you can't see, and that's a job for professional leak detection rather than another billing cycle of guessing.
