The Hidden Cost of Water: 5 Warning Signs Every Property Owner Should Know

Water is something most of us take for granted until there is a problem.
A higher-than-usual water bill, a toilet that keeps running, or a wet spot on the ceiling may seem like small issues. But when water problems go unnoticed, they can lead to wasted water, higher operating costs, maintenance issues, and, depending on the situation, property damage.
For multifamily property owners, water management deserves extra attention because a property may have multiple units, shared plumbing, common areas, landscaping, and irrigation systems.
At Strategic Growth Real Estate, we believe good property management starts with being proactive. Here are five warning signs every property owner should know.
1. Your Water Bill Suddenly Increases
An unexpected increase in water usage is one of the easiest warning signs to notice.
A higher bill does not automatically mean there is a leak. Changes in occupancy, weather, landscaping, irrigation, or tenant usage can all affect water consumption.
However, if usage increases without an obvious explanation, it is worth investigating.
The California Department of Water Resources recommends tracking water bills and meters to help manage water use and identify potential problems. (water.ca.gov)
The takeaway: Don't just look at the amount of the bill. Look for changes in the property's normal pattern.
2. Your Water Meter Shows Unexpected Activity
A water meter can be another useful tool.
If all known water sources are turned off and the meter continues to show water use, there may be water flowing somewhere in the property.
This is a warning sign, not proof of a leak. Some properties have systems that use water automatically, and meter setups can vary. If something appears unusual, further investigation may be appropriate.
For multifamily properties, understanding normal water usage can make unusual activity much easier to recognize.
3. A Toilet, Faucet, or Fixture Keeps Running
Some water problems are easy to overlook because they happen every day.
A toilet that keeps running, a dripping faucet, or a fixture that does not shut off properly can result in unnecessary water use if the problem continues.
For tenants, the best thing to do is simple: report the problem.
For owners and property managers, having a clear process for receiving and responding to maintenance requests can help prevent small issues from becoming larger ones.
California's Department of Water Resources recommends repairing leaks, including leaky toilets, and using water-efficient fixtures where appropriate. (water.ca.gov)
4. You Notice Moisture, Stains, or Musty Odors
Not every water problem is visible.
Pay attention to:
New stains on walls or ceilings
Damp flooring
Swollen cabinets
Peeling or bubbling paint
Persistent moisture
Musty odors
Mold-like growth
These signs do not automatically mean there is a plumbing leak. Condensation, weather, and drainage problems can create similar conditions.
Still, unexplained moisture should be reported and investigated.
California's Attorney General provides information about landlord responsibilities concerning habitable rental housing, including working plumbing and waterproofing.
When in doubt, communicate early.
5. Your Landscaping May Be Using Too Much Water
Water waste does not only happen indoors.
For multifamily properties, landscaping and irrigation can also account for significant water use. A broken sprinkler, damaged irrigation line, or poorly timed watering schedule can waste water.
Property owners and managers can periodically check for:
Broken or misaligned sprinklers
Water spraying onto sidewalks
Areas that remain unusually wet
Inefficient irrigation
Opportunities for water-wise landscaping
California's Department of Water Resources recommends efficient irrigation and water-wise landscaping where appropriate.
What About Rebates?
Some cities and water agencies offer incentives for water-saving improvements, including turf replacement.
For example, LADWP currently offers turf-replacement incentives for qualifying customers, including certain multifamily properties. Program requirements, funding, eligibility, and rebate amounts can change, and pre-approval may be required. Property owners should always confirm current requirements directly with their local water agency before starting a project.
What Can Tenants Do?
Water management is a shared effort.
Tenants can help by:
Reporting leaks promptly
Turning off faucets when water is not needed
Taking shorter showers
Using dishwashers and washing machines efficiently
Reporting unusual moisture or water damage
Tenants are not expected to diagnose plumbing problems. The important thing is to report concerns early so the appropriate person can investigate them.
A Simple Water Check for Property Owners
Property owners and managers can make water monitoring part of their regular property management routine:
1. Review water bills for unusual changes.
2. Monitor water usage and understand what is normal for the property.
3. Pay attention to maintenance requests involving plumbing or moisture.
4. Check common areas and landscaping for visible signs of water waste.
5. Keep maintenance records to identify recurring problems.
These simple steps can help owners stay informed and respond proactively.
Final Thoughts
Water problems do not always start with a flooded room.
Sometimes the first warning is a higher water bill, unexpected meter activity, a running toilet, a small stain, or an irrigation problem.
None of these signs automatically means there is a leak. But they can be reasons to take a closer look.
For property owners and managers, the takeaway is simple:
Monitor. Communicate. Investigate. Maintain.
At Strategic Growth Real Estate, we believe proactive property management is about more than responding when something breaks. It is about protecting the property, keeping owners informed, and creating a better experience for tenants.
