Sprinkler system installation cost

What a new sprinkler system costs per square foot, per zone and for a typical lawn size, published cost by system type, and what pushes the price toward the top of the range.

Installing a sprinkler system costs $3,000 to $10,000 on average for a quarter-acre lawn, or $0.50 to $2.50 per square foot, according to published contractor pricing. Per zone, expect $600 to $2,000, and the average lawn needs three to five zones with five to ten heads each.

The total depends on the sprinkler type, the number of zones, your location and how difficult the yard is to work with. A simple, regular-shaped lawn sits at the bottom of every range below; a sloped, irregular or rocky yard sits at the top.

Measure	Published figure
Cost per square foot	$0.50 to $2.50
Cost per zone	$600 to $2,000
Total, quarter-acre lawn	$3,000 to $10,000

The per-square-foot rate and the quarter-acre total are both published as-is by the source and do not multiply out exactly (a quarter acre is 10,890 sq ft, so the per-square-foot rate alone implies a wider range); treat the quarter-acre total, not the per-square-foot rate times lot size, as the more reliable estimate for a typical lawn.

Cost by system type

Irrigation systems don't all cost the same per square foot. An above-ground system is the cheapest to install and the simplest to repair later, which suits smaller, straightforward lawns. An in-ground (underground) system costs more up front because the lines have to be trenched and buried, but it stays out of sight and holds up better against damage. Drip irrigation costs more per square foot than either lawn-focused option, and fits garden beds and specialty plantings rather than open lawn.

System type	Cost per square foot
Above-ground	$0.50 to $1.50
In-ground (underground)	$1.00 to $2.50
Drip irrigation	$1.50 to $4.50

Cost by number of zones

A zone is a section of the system that runs on its own valve and schedule. The average lawn needs three to five zones, with five to ten sprinkler heads on each. Many installers quote a rough $1,000 per zone, but the published range below runs closer to $600 to $2,000 per zone, so treat the round number as a starting estimate rather than the figure to hold a quote against.

Number of zones	Published installed cost
1	$600 to $2,000
2	$1,200 to $4,000
3	$1,800 to $6,000
4	$2,400 to $8,000
5	$3,000 to $10,000
6	$3,600 to $12,000
7	$4,200 to $14,000

Cost by yard size

Contractors often charge lower per-square-foot rates for larger yards. A yard several times the size does not necessarily cost several times as much.

Lot size	Square footage	Published installed cost
1/8 acre	5,445 sq ft	$2,000 to $7,000
1/4 acre	10,890 sq ft	$3,000 to $10,000
1/2 acre	21,790 sq ft	$5,000 to $14,000
1 acre	43,560 sq ft	$8,000 to $20,000

What pushes the price toward the top of the range

• Irregular or sloped yards: more piping, more zones and more labour. Difficult projects can reach $4.00 per square foot, well above the standard range.
• Automatic upgrades: rain sensors, Wi-Fi monitoring and similar features add $20 to $300 to the base cost.
• Backflow prevention: required in most areas for code compliance. Installing a backflow preventer costs $450 to $1,700; repairing one runs $150 to $500.
• Trenching for underground lines: $5 to $12 per linear foot on its own, or roughly $500 to $1,200 for an average lawn needing around 100 linear feet.
• Removing an old system: if an existing system is coming out first, expect an extra disposal fee on top of the installation price.
• Permits and inspections: some contractors handle these and fold the cost into their quote; ask before assuming it is included.
