Why Los Angeles buildings carry water risk
Los Angeles is a city of older apartment buildings. Hundreds of thousands of units fall under the city's Rent Stabilization Ordinance, which applies to buildings built on or before October 1, 1978. The city's soft-story program alone covers thousands of pre-1978 wood-frame buildings with tuck-under parking. Galvanized steel supply pipe was common before the 1960s, and once its zinc coating wears away it corrodes from the inside and leaks. A failed fitting upstairs runs down through every unit below and into the garage.
The newer stock carries its own risk. Downtown's 1999 adaptive reuse ordinance helped create thousands of homes inside existing buildings, and since February 1, 2026 a citywide ordinance fast-tracks conversions of buildings at least 15 years old. Each conversion threads new kitchens and bathrooms through floors built for offices. New towers fail too. Push-fit fittings, appliance connections and HVAC condensate lines are usually the first to let go, often within the first few years of occupancy.
Then cost and weather decide how expensive a leak gets. Commercial buildings and apartment buildings with five or more units on one meter pay a sewer charge estimated from the water they buy, so a hidden leak is billed twice. Much of the year's rain arrives in a few storms, like the two days in February 2024 that brought Los Angeles 7.03 inches. Eddy's 24/7 monitoring center in Toronto confirms every alert and can close a valve remotely when the building's response plan calls for it.
Where leaks start in Los Angeles buildings
Pre-1978 apartments on original pipe
Hundreds of thousands of rent-stabilized units sit in buildings from 1978 or earlier, and some still run original supply lines. Galvanized steel, common before the 1960s, corrodes from the inside until it leaks. The first sign is often a stain in the unit below or water in the garage.
Shaking strains joints and overhead pipe
A soft-story retrofit strengthens the frame, not the supply lines. In the 2001 Nisqually earthquake in Washington, most damage to building contents came from water from broken overhead pipes. Automatic shutoff closes the water when a line lets go.
A hidden leak is billed twice
Commercial buildings and apartment buildings with five or more units on one meter pay a city sewer charge estimated from the water they buy. LADWP raised water bills again in January 2026. Flow monitoring finds the quiet waste behind walls and under floors.
Conversions add plumbing to old shells
Office-to-housing conversions add kitchens and bathrooms to buildings never plumbed for them, and a citywide ordinance now fast-tracks them. New construction has its own early failures at push-fit fittings and appliance connections. The same system covers a building from construction through occupancy.
Smart leak detection in Los Angeles
A smart water leak detection system pairs wireless sensors and smart meters with automatic shutoff, so a Los Angeles building catches a leak in seconds instead of discovering it from a ceiling stain. Eddy runs the full stack as one managed program with a staffed 24/7 monitoring center on the chain.
Sensors plus flow intelligence
3-in-1 wireless sensors watch high-risk spaces for water, temperature and humidity while smart meters flag abnormal flow against thresholds learned from the building's own baseline.
No building Wi-Fi needed
Devices run on Eddy's own LoRaWAN network at 915 MHz, a long-range radio that holds a signal through concrete. Gateways backhaul over Ethernet or LTE cellular, and with cellular backhaul monitoring stays up even if building internet goes down.
Shutoff plus a live response
Automatic valves close the moment a configured rule fires, and Eddy's monitoring center calls the building's contacts within minutes of every alert. Every confirmed event closes with a Leak Incident Report.

Coverage map
How Eddy works in a Los Angeles building.
In Los Angeles, ground movement stresses joints and connections over time, and water is expensive and tightly managed. Turn the building to see where sensors, meters and valves sit, then run a leak through the system, from the first drop to the monitoring center's response.

What happens in a leak, step by step
- A washing machine supply hose bursts in a suite upstairs.
- Eddy H2O under the washer detects water and sends the alert over LoRaWAN.
- The building's gateway relays it. Your team and the 24/7 monitoring center are alerted at the same time.
- A shutoff rule closes the suite's Eddy IQ valve. The water stops at the source.
- An operator confirms the alert and calls your on-site team through the escalation protocol.
Automatic shutoff is configured per building. Some sites use operator-coordinated isolation instead.
Smart sensors at every leak point
Eddy places point-of-leak sensors and smart flow meters where water damage actually starts in Los Angeles buildings, from the mechanical room to a laundry hose, so a leak is caught at the source and shut off before it spreads.

Mechanical rooms
Boilers, water heaters and main risers, where a single failure floods fast.

HVAC and fan coils
Heat exchangers and condensate lines that drip behind walls and ceilings.

Kitchens
Supply lines, shutoffs and appliance connections under and behind the sink.

Bathrooms
Toilets, vanities and concealed in-wall fixtures on every floor.

Laundry
Washer hoses and laundry connections, a top source of overnight leaks.
Every minute changes the bill.
A leak gets bigger the longer it runs. Eddy detects in seconds and the monitoring center escalates within minutes, so the same failure is contained around minute two. Unmonitored, an after-hours leak runs six to eight hours before anyone arrives.
The leak starts at minute zero. Eddy contains it around minute two. Unmonitored, the same leak runs six to eight hours before staff arrive, and that red stretch is the avoided claim.

Water benchmarking under LA's EBEWE program
Under the Existing Buildings Energy and Water Efficiency program, buildings of 20,000 square feet or more, condos included, must benchmark whole-building energy and water use by June 1 each year, and the city publishes each building's water use. Every five years they also owe a water audit and retro-commissioning, and one exemption requires a certified 20% drop in water use intensity. A hidden leak shows up in those public numbers. Monitoring does not file the report. It documents the leak and flow history behind the numbers.
A team behind every alert
A 3 a.m. alert is one chime. Nobody is awake to hear it.
Fast response is not just the hardware. The technology sees the water in seconds, and the managed service behind it, a monitoring center that calls your team within minutes, turns that into a contained event before it becomes a claim.
Tuned by real events
Built over a decade in operating buildings.
Eddy has been inside buildings since 2014. Sensor placement, alert thresholds and the monitoring-center playbook are tuned by what real water events across our monitored properties keep teaching us.
Built for the building
Sized to how the water system behaves.
Multi-family stacks, commercial towers, hospitality suites, course-of-construction projects. Each water system has its own failure pattern. The coverage map, response chain and shutoff sequence are scoped to the property in front of us, not a template.
Detect, contain, document
Every event leads to a closed incident.
Sensors find where water escaped. Automatic shutoff isolates the affected zone. The 24/7 monitoring center calls your team within minutes and stays on it until it's closed, with a Leak Incident Report on file.
Trusted on a major Southern California campus
Eddy protects institutional buildings including a major Southern California university, where continuous monitoring guards dense, high-value space. Escalation and shutoff are handled around the clock by the monitoring center.

Los Angeles water leak detection FAQ
Do you serve Greater Los Angeles?
Yes. Eddy protects commercial, institutional and multifamily buildings across the LA basin, including Los Angeles, Santa Monica, Beverly Hills, West Hollywood, Culver City, Glendale, Burbank, Pasadena and Long Beach.
Does Eddy account for seismic risk?
Yes. A soft-story retrofit strengthens the frame, but supply lines and fittings can still break when the ground moves. Eddy watches flow and the presence of water around the clock and can isolate a line automatically when a leak appears after ground movement.
Can Eddy support California submetering?
Under SB 7, multiunit and mixed-use buildings that applied for a water connection after January 1, 2018 must have the water to each dwelling unit measured by a meter or submeter. Eddy smart metering measures water use at the unit level to support resident billing, and its flow monitoring watches the same water for leaks and can shut it off automatically or on a remote command.
Does our SB 721 balcony inspection cover the plumbing?
No. SB 721 requires owners of apartment buildings with three or more units to have wood-supported balconies, decks, stairways and walkways more than six feet up, along with their waterproofing, inspected by January 1, 2026 and every six years after. It covers those structures outside the walls, not the supply lines, valves and fittings inside, which is where Eddy's sensors and flow monitoring work.
Will monitoring help our insurance in California?
State Farm General began nonrenewing its California commercial apartment policies in 2024, and in 2025 the state raised FAIR Plan commercial limits to help associations priced out of coverage. Eddy's technology is approved by most insurers across North America to provide deductible or premium savings. Programs have documented premium savings of up to 20%, and deductible reductions of up to 80% have been documented at individual properties.
How Eddy works
What is Eddy Solutions?
Eddy Solutions is managed water leak detection for builders, commercial asset managers and property managers, hospitals, hotels and conference centers, data centers and multifamily residential buildings across the Greater Los Angeles Area. It combines point-of-leak and flow sensors, automatic shutoff, building wireless connectivity, a 24/7 monitoring center and insurance-grade reporting into one program from one vendor, so a leak is detected, contained, escalated and documented without your team running the response.
Eddy monitors 150,000+ active devices across North America and has prevented an estimated $98M (USD) in property damage last year alone. Aon's independent study found Eddy would have positively affected 58% of water-loss claims in commercial real estate.
How do we choose a commercial water leak detection company in the Greater Los Angeles Area?
Look for five things. Sensors where leaks start, not only a meter on the main. Shutoff valves that close on their own when water runs. A staffed monitoring center that calls your team instead of only sending an app alert. Wireless coverage that holds a signal through concrete to mechanical rooms and parking levels. And a documented record of every event that your insurer can read.
Eddy covers all five for buildings across the Greater Los Angeles Area, from a single tower to a full portfolio, with 150,000+ active devices in the field.
What happens after hours?
The 24/7 monitoring center is the after-hours response. Trained operators confirm every alert, escalate per the building's contact list, support the on-call contact, and stay on the line until the water is off and the response is verified.
Will this affect our insurance?
Yes. Eddy Solutions' technology is approved by most insurers across North America to provide deductible or premium savings. Given differences in asset types and building risk profiles, insurance incentives are not uniform. For specific insurance questions related to your property in the Greater Los Angeles Area, please reach out directly to sghanbarian@eddysolutions.com.
How is the system sized for a building, and what does it cost?
Eddy's team walks the building, or reviews the construction drawings, and produces a tiered design matched to the asset class, water systems and insurance program. Our first step is an exploratory call with the relevant stakeholders to understand the problem you are looking to solve. Proposals come from our technical team in 7 days or less.
You can also get started immediately with our Build Your System tool at eddysolutions.com/build-your-system.
Do we have to open walls to install Eddy?
No. Sensor installs need no drywall cuts. Wireless sensors sit where leaks start, at fixtures, appliances, fan coils and the foot of each riser, and Eddy provisions and configures the meters and valves on the lines that need them.
What is smart water leak detection?
Smart water leak detection uses connected sensors and flow meters to watch a building's plumbing in real time, instead of waiting for someone to find a leak. Point-of-leak sensors catch water at the source and smart flow meters spot an abnormal run or a burst riser, and the system can shut the water off automatically or on a remote command. With Eddy, a 24/7 monitoring center acts on every alert, so detection turns into a response, not just a notification.
How is commercial water leak detection different from a home leak detector?
A home leak detector is usually a single sensor that pings an app. Commercial and multifamily leak detection has to cover dozens of risers, suites and mechanical rooms, hold a signal through concrete and steel and produce the documented response insurers expect. Eddy is built for that scale, with building-grade LoRaWAN wireless, point-of-leak and flow coverage across the property, automatic shutoff up to building mains and a managed 24/7 monitoring center.
What is the difference between leak detection and water leak protection?
Leak detection finds the water. Water leak protection stops the loss. Detection on its own is an alert that still needs someone to act on it. Eddy pairs detection with automatic shutoff and a 24/7 monitoring center that escalates the alert and closes the water, so the building is protected, not just alerted.
Does Eddy work for both multifamily and commercial buildings?
Yes. Eddy protects multifamily and condo towers, Class A offices and mixed-use buildings, hospitality, institutional and industrial properties and active construction sites. The same managed program tunes the sensor density, shutoff strategy and reporting to how each building's water system behaves. See the full product suite at eddysolutions.com/products.
