No. LARS runs on the water submeters and transmitters your property already has. Connecting is a read-only data feed using the meter-platform credentials you already use — no devices, no installers, no capital cost. That's the core difference from hardware-based leak detection, which typically runs $200–600 per unit before it detects anything.

Standard metering alerts fire on usage spikes, which is why most of them are false — a filled bathtub and a burst pipe look the same to a threshold. LARS learns each unit's normal behavior from its own history and flags only when the pattern genuinely changes. It also catches what thresholds miss entirely: slow overnight leaks, baselines creeping upward for weeks, and usage in vacant units. Every alert includes plain-language evidence for why it fired.

Yes — that's the Premium plan. When a leak is confirmed in a unit, the resident is notified directly: an AI voice agent calls and explains what was found, backed by SMS text and a personalized email — in English or Spanish. It gets fixtures fixed faster, creates a logged, timestamped record that notice was given, and ends the billing disputes that start with "nobody told me about the leak." And because LARS needs no in-unit hardware, it's resident notification without a single device on the wall.

The Free plan — view-only detection with your full dashboard and leak list — is free forever for one property up to 100 units, no card required. Paid plans are priced per unit per month and quoted for your portfolio, with rates that scale down as your unit count grows — so LARS runs a fraction of the water loss it identifies at any scale. And the 60-day pilot costs nothing to evaluate: your property, your data, your numbers.

One property of your choice, a read-only data feed, and 60 days. We pull your meter data (with up to six months of historical backfill), run LARS, and return a leak and billing exception report — in dollars, at your utility's actual rates. Your property, your data, your numbers. No PMS change, no cost to evaluate, no commitment past day 60.

LARS syncs readings from your meters hourly and evaluates every unit's behavior against its own history. Detection speed depends on the leak: a catastrophic open-flow event stands out within hours of onset, while a slow or intermittent leak is confirmed over a few days as the pattern proves itself — either way, long before it would surface on a water bill. Once a leak is confirmed, severity decides who's told: your maintenance team gets an immediate alert with the unit, flow rate, and how long it's been running; managers see critical events right away and everything else in the weekly summary; and on Premium, the resident is notified directly. Low-confidence signals notify no one — LARS monitors them silently until the evidence resolves them, so every alert your team receives is one worth acting on.
