Quick answer: A new in-ground sprinkler system in Lacey Township typically costs $3,200 to $6,500 installed for most homes. Small lots with 4 to 5 zones come in at the low end, and half-acre properties with 6 to 8 zones at the high end. Larger and wooded lots run more.

What Moves the Number in Lacey
Zone count
This is the biggest factor on any quote. Zones are set by how much water your supply delivers and how the yard is laid out, not by lot size alone. A simple rectangle of lawn needs fewer zones than the same square footage broken up by beds, a pool, and a side yard.
Sandy soil helps
Lacey sits on fast-draining sand. Trenching through it is quicker than cutting through the clay you find farther inland, which keeps labor down.
Trees do not
The wooded lots west of Route 9 are a different job. Roots slow the trenching, and mature oaks and pines block spray, so those yards often need more heads to get even coverage.
Well or municipal water
Homes on a private well need the system designed around what the pump can deliver. Sometimes that means more, smaller zones. See well water vs. city water for irrigation in Lacey Township.
Controller choice
A standard controller is included. A smart Wi-Fi controller adds roughly $180 to $280 and adjusts watering to the weather for you.
What You Should Expect to Be Included
- A design that covers every part of the lawn head to head, with no dry corners
- A backflow preventer, which New Jersey requires on irrigation connected to municipal water
- A rain sensor, also required on new installations in New Jersey
- Permit handling where the township requires one
- A walk-through of every zone before we leave
Yearly Costs After Installation
Budget for a spring startup at $75 to $110 and a fall winterization at $85 to $150. Skipping the winterization is what turns a new system into a repair bill.
Is It Worth It on a Small Lot?
For most Lacey homeowners the answer comes down to time and water. A properly zoned system waters at dawn, only where it is needed, and usually uses less than dragging a hose around. Our in-ground system vs. hose comparison runs the numbers.
