Rain Sensor Installation in The Villages
Florida requires a working rain sensor on every automatic irrigation system in the state. Installing or replacing one runs $100 to $250, and includes actually testing that it interrupts the system, not just bolting a sensor to the gutter and calling it done.
The law, in plain terms
Florida Statute § 373.62 states that anyone with an automatic landscape irrigation system “must properly install, maintain, and operate technology that inhibits or interrupts operation of the system during periods of sufficient moisture.” It goes further for contractors specifically: “A licensed contractor who installs or performs work on an automatic landscape irrigation system must test for the correct operation of each inhibiting or interrupting device or switch on that system,” and must install a new one or repair an existing one if it’s missing or not working, before finishing any other work on the system.
In plain terms: if we’re at your property for any reason and your rain sensor is dead or missing, that gets addressed as part of the visit, not left for another day. Local governments that adopt the statute’s model ordinance can fine a non-compliant system, up to $250 for a repeat violation under the model penalty schedule, though enforcement varies by jurisdiction.
What a rain sensor actually does
A rain sensor sits in-line with the controller’s power circuit to every zone valve. When it detects enough rainfall, it breaks that circuit and the whole system skips its next scheduled run, even if the controller’s program says to water. It’s a mechanical or electronic override, not a smart feature the controller has to be told to use.
How rain sensors fail, and what it looks like
- Stuck “wet”: the sensor thinks it’s still raining long after it stopped, and silently prevents every zone from running. This is one of the most common causes of a system that appears to have failed completely, since the symptom (nothing runs) looks identical to a dead controller or a power problem, but the fix is much smaller. See our rain sensor not stopping the system page, which actually covers the opposite failure (stuck dry): both directions are common enough to have their own page.
- Stuck “dry” or disconnected: the sensor never trips, so the system keeps running through real rainfall, which shows up as a water bill that doesn’t match the weather and, over time, general overwatering.
- Physical damage: cracked housing from age or a storm, or a sensor knocked loose from its mount.
What it costs
| Job | Range |
|---|---|
| Rain sensor installation (new, none currently present) | $100 to $250 |
| Rain sensor replacement (existing one failed) | $100 to $250 |
Pricing is the same whether it’s a first-time install to bring an older system into compliance or a straight swap of a failed unit.
Lightning is a real cause here
Florida leads the country in lightning-strike density, and Central Florida sits in the middle of it. A power surge from a nearby strike can travel through the wiring and damage a rain sensor along with a controller or a valve solenoid on the same circuit, which is one reason a “dead system” after a storm is worth a full diagnostic rather than assuming it’s just one part.
The variance option, briefly
Florida law also allows for a variance from day-of-week watering restrictions for properties using a certified soil-moisture-sensor system with remote monitoring, under conditions set and enforced by the applicable water management district and a monitoring entity (a local government, CDD, HOA, or utility). It’s a real provision but a narrow one, and it requires more than an off-the-shelf smart controller to qualify. Ask if you’re interested and we’ll walk you through what it would actually take, honestly, rather than oversell a standard rain sensor as something it isn’t.
Getting it installed
If your system doesn’t currently have a working rain sensor, or you’re not sure whether yours is functioning, that’s exactly what this visit is for. Full pricing for every job is on the pricing page.

Frequently Asked Questions
Am I legally required to have a rain sensor?
Yes. Florida Statute 373.62 requires every automatic landscape irrigation system in the state to have a working rain sensor or equivalent shutoff device, and requires any licensed contractor doing work on your system to test it and fix or replace it before finishing other work. This applies to systems already installed, not just new construction.
How much does it cost to install one?
$100 to $250 installed, which includes mounting the sensor, wiring it into the controller's sensor circuit, and testing that it actually interrupts the system when it should.
My system stopped running for no reason. Could it be the rain sensor?
It's one of the most common causes. A rain sensor stuck in the 'wet' position sits in the same circuit as the controller's power to every zone valve, so a failed sensor can look exactly like a total system failure rather than a small sensor problem.
Can I get an exemption from watering-day restrictions with a smart controller?
Florida law does allow a variance from day-of-week watering restrictions for certified soil-moisture-sensor systems under specific monitoring conditions set by the local water management district. It's a real but narrow provision, not something a standard rain sensor or off-the-shelf smart controller automatically qualifies for; ask us if you're interested and we'll tell you honestly whether your setup would likely meet it.
