Who is Responsible for the Water Bill After a Leak?

Finding an unusually high water bill due to a leak can be an unpleasant surprise for any homeowner. But who is ultimately responsible for covering the costs – the property owner or the tenant? When a costly water leak occurs, determining financial liability depends on several factors.

Responsibility Depends on the Source

The first question to answer is where did the leak originate? That will determine whether the landlord or renter shoulders the bill.

Property owner responsibilities:

  • Leaks in supply lines: The property owner is generally responsible for repair and water charges from leaks in the main supply line from the street to the house as well as any supply lines branching off to fixtures inside the home. These are considered part of the property itself.

  • Structural leaks: Leaks related to defects in the building like cracked pipes inside walls, leaky roofs, faulty appliances provided by the landlord, etc. are the owner’s responsibility.

  • Negligence: If the landlord fails to properly maintain the plumbing system or delays repairs after being notified, they may be liable for higher water bills.

Tenant responsibilities:

  • Fixture leaks: Renters are usually responsible for repair costs and water bills related to leaks from fixtures like sinks, toilets, tubs, washing machines, and other appliances they own.

  • Negligence: Tenants may be liable if they fail to report leaks promptly or cause damage by inappropriate usage.

Factors Impacting Responsibility

While the general guidelines above apply, there are a few other factors that can impact who pays for water leak bills:

  • Lease terms: The lease agreement may specify who is responsible for certain types of leaks or damage. This will dictate financial liability unless it violates state laws.

  • Local laws: Some states require landlords to pay for water bills, repairs, or damages from any leaks regardless of source. Check your state’s tenant-landlord regulations.

  • Insurance policies: Homeowner’s or renter’s insurance may cover some costs related to water damage. Review policies to understand coverage.

  • Leak forgiveness programs: Many municipalities offer leak forgiveness to offset the spike in water bills after qualifying leaks are repaired. This reduces the financial impact on both parties.

  • Shared liability: In rare cases where blame is unclear, landlords and tenants may mutually agree to split leak-related costs. But there should be written documentation of the arrangement.

Best Practices to Prevent Costly Leaks

While responsibility varies case-by-case, there are proactive steps both property owners and renters can take to minimize the likelihood of leaks and detect them early:

Property owner best practices:

  • Maintain all supply lines, gutters, appliances, fixtures, and infrastructure regularly.

  • Inspect for leaks during tenant turnover.

  • Encourage tenants to report drips or damp spots immediately.

  • Install smart leak detectors to alert you to flow after hours.

  • Check tenant water usage data for abnormalities if supply lines are metered separately.

Tenant best practices:

  • Review lease to understand liability for leaks and repairs.

  • Inspect appliances and fixtures and report drips, cracks, or damp spots right away.

  • Conserve water and fix dripping faucets to reduce chances of leaks.

  • Know where your main shutoff valve is and how to use it if pipes burst.

  • Alert landlord and insurance company about significant water damage.

What to Do About a Costly Leak

If you receive an expensive water bill caused by a leak, take these steps:

  1. Determine the source – Supply line, structural, or appliance/fixture? Who owns the equipment?

  2. Review lease and laws – Who is liable based on your lease and local statutes?

  3. File insurance claims – Both parties should contact insurance to see if covered.

  4. Repair leak ASAP – This may qualify you for leak forgiveness programs.

  5. Request billing adjustments – Follow utility procedures to seek reduced charges.

  6. Negotiate if needed – If liability is unclear, compromise on costs. Get it in writing.

  7. Update procedures – Change maintenance schedules, inspection processes, etc. to avoid recurrence.

Costly Leaks Can Be Avoided

Water leaks leading to sticker shock bills can create tension between landlords and tenants. But following best practices, understanding liability, fixing problems promptly, leveraging insurance and forgiveness programs, and negotiating reasonable cost shares can diffuse the situation. Open communication and collaboration to prevent leaks will serve all parties best in the long run.


Are you charged for a water leak?


This means that as soon as the water passes through the meter, you will be charged for it. Consequently, if there is a leak at any point after water passes through your water meter, you are responsible for both the repair of the pipe and the payment for that metered water whether you use it or not, including leaks.

Does a leak increase water bill?


Leaking toilets, pipes and taps can cause an increase in your bill.

Is a water leak my responsibility?


If you own your home, you’re responsible for any leaks within the boundary of your property. This includes the water supply pipe, internal pipes, fittings and appliances. If you’re a tenant, this is your landlord’s responsibility to fix and maintain. Leaks in public places are our responsibility to fix.

What is a leak allowance?


A leakage allowance is offered on a one-off basis and will ensure you don’t have to pay for any additional costs due to a leak. We’ll review your recent usage and remove any additional costs that are above your normal bill amount.
