Sprinkler System Cost: What a Full Irrigation Install Runs in 2026

A new in-ground sprinkler system typically costs $1,600 to $5,500 installed in 2026 for a standard residential lawn, usually broken down per zone at roughly $585 to $1,335 per zone. Most homes need 4–8 zones depending on yard size and layout.

What actually drives the cost

Number of zones. More zones mean more valves, trenching, and heads — the single biggest cost driver.
Yard size and layout. Irregular shapes, slopes, and obstacles add design and labor time.
Water source and pressure. Tying into an existing line vs. a new tap or booster pump changes the job.
Controller type. A basic timer costs far less than a smart, weather-based controller.
Soil and trenching conditions. Rocky or clay soil takes longer to trench than sandy soil.

Typical job examples

Lot size	Zones	Typical installed cost
Small (1/4 acre)	4–5	$1,600 – $2,600
Medium (1/2 acre)	6–8	$2,600 – $4,300
Large (1 acre+)	8–12	$4,300 – $5,500+

These are reference ranges — real pricing depends on the property, water source, and zone count.
