Most homeowners pay $1,700–$5,000 to install an in-ground sprinkler system on a typical quarter-acre lot, with averages of about $2,500–$3,000. Contractors usually charge around $500–$1,000 per zone, and large or complex systems can reach $10,000 or more (Angi, HomeGuide, Fixr and Forbes Home data, as of October 2026).

An automatic sprinkler system saves hours of hand watering and, with a good controller, can use less water than hoses and portable sprinklers. It's most worth it for lawns in dry summers, new sod or seed, and homes where you're away often.
This guide covers installed costs by zone, yard size and system type, a line-item budget and the add-ons (backflow, permits, smart controllers) that quotes often leave out. If you already have a system that's leaking or not turning on, see our sprinkler system repair cost guide instead.
Average cost
Installed costs for residential lawn sprinkler systems, national averages as of October 2026:
| Scenario | Typical range | Notes |
|---|---|---|
| Small yard, 1–3 zones | $600–$4,000 | About $500–$1,000 per zone; townhomes and small lots |
| Typical quarter-acre lot, 4–6 zones, in-ground | $1,700–$5,000 | Most common project; averages about $2,500–$3,000 |
| Half-acre lot or 7+ zones | $3,500–$7,000 | More pipe, trenching and heads |
| 1 acre or complex system (smart controller, drip beds) | $7,000–$13,600 | Large lots, rocky soil, mixed spray and drip zones |
Sprinkler system cost by number of zones
Installed prices per system reported by Angi, Fixr and Forbes Home:
| Zones | Typical installed cost |
|---|---|
| 1 zone | $500–$1,000 |
| 2 zones | $1,000–$2,000 |
| 3 zones | $1,950–$4,000 |
| 4 zones | $2,000–$5,000 |
| 5 zones | $3,250–$6,000 |
| 6 zones | $3,000–$6,500 |
Cost by system type
| System type | Cost per quarter acre | Good to know |
|---|---|---|
| Above-ground (hose-fed, staked heads) | about $450 | Cheapest, but manual and visible |
| Drip irrigation | $450–$650 | Efficient for beds, shrubs and gardens |
| Automatic in-ground (underground) | $1,740–$4,700 | Buried pipe, pop-up heads, timer |
Cost breakdown: materials, labor, permits and extras
Line-item estimate for installing a 4–5 zone in-ground sprinkler system on a quarter-acre lot with a basic Wi-Fi controller. Ranges are national, as of October 8, 2026.
| Cost item | Typical range | What it covers |
|---|---|---|
| Materials (pipe, heads, valves, controller) | $700–$1,700 | Polyethylene or PVC pipe, 10–30 heads, zone valves, controller |
| Labor and trenching | $600–$1,800 | Trenching at $4–$12 per linear foot plus 8–16 hours of install labor |
| Backflow preventer, permit and inspection | $300–$1,000 | Required for city-water connections in many areas; permits $35–$200 |
| Lawn repair along trenches | $100–$300 | Re-seeding or sod patches over trench lines |
| Contingency (about 10%) | $200–$500 | Rocky soil, tree roots, extra heads |
| Estimated total | $1,900–$5,300 | Before any discounts or rebates |
Backflow and permit costs are where quotes differ most, so confirm they are included before you compare totals.
What affects the price
- Number of zones. Zones drive most of the price, because each one needs its own valve, wiring and pipe run. Expect about $500–$1,000 per zone; a typical lawn uses 4–6 zones.
- Yard size. Bigger lots need more pipe, heads and trenching. Angi puts an underground system at about $1,740–$3,400 for 1/4 acre and $3,480–$6,800 for 1/2 acre.
- Materials. Sprinkler heads run $2.50–$40 each, from basic pop-up sprays to gear-driven rotors. Drip lines for beds cost less than spray zones, and premium valves and heads add to the total.
- Controller (smart or basic). A basic timer is inexpensive, while a Wi-Fi smart controller costs about $50–$300 and rain or soil-moisture sensors $25–$50 each. A smart upgrade on a full system typically adds $200–$500.
- Trenching. Trenching typically costs $4–$12 per linear foot, or about $500–$1,200 for an average lawn. Rocky or hardpan soil and many tree roots push the price up.
- Backflow preventer and permits. Connecting to city water usually requires a backflow preventer, which costs about $450–$1,700 installed, plus a permit at $35–$200. Angi estimates plans, inspections, permits and backflow together at about $800.
Ways to save
- Design zones by plant type and sun exposure so you don't pay for more zones than you need; ask the installer to justify the count.
- Use drip irrigation for shrubs and beds, which costs far less per area than spray zones and uses less water.
- Install the system before laying new sod or seed so you don't pay to repair a new lawn along every trench line.
- Ask your water utility about rebates for WaterSense-labeled smart controllers and rain sensors before you buy one.
- Book installation in late summer or fall, after the spring rush, when contractors often have more openings.
- Get at least three itemized quotes listing the number of zones, head types, pipe material, controller model, backflow device and permits.
Related questions people ask
What is the cost to install a sprinkler system?
The cost to install a sprinkler system on a typical lawn is $1,700–$5,000, depending mostly on the number of zones. Angi reports an average of about $2,550, while HomeGuide puts quarter-acre systems at $3,000–$10,000 when backflow, smart controls and difficult soil are included.
How much does sprinkler system installation cost per square foot?
Sprinkler system installation cost ranges from about $0.20–$1 per sq. ft. for a standard underground system (Angi) to $1–$2.50 per sq. ft. for more complex in-ground jobs (HomeGuide). Larger lawns cost less per square foot.
How much does an underground sprinkler system cost?
An underground (in-ground) sprinkler system usually costs $1,740–$4,700 per quarter acre, and about $6,000–$13,600 for a full acre. That includes buried pipe, pop-up heads, valves and an automatic controller.
How to get an accurate quote
Ask at least three licensed irrigation contractors for written, itemized quotes. Give each the same information:
- A sketch or aerial photo of your lot showing lawn areas, beds, slopes, trees and where the water line enters the house.
- Your water pressure and meter size if you know them; the installer will test them on site.
- What you want watered (lawn only, or beds and gardens with drip) and whether you want a smart controller.
- Ask what is included: backflow preventer and testing, permits, lawn repair along trenches, winterization, and labor and parts warranties.
FAQ
How much does it cost to add a zone to a sprinkler system?
Adding a zone to an existing system usually costs $500–$650, according to Fixr, assuming the controller has an open station and the main line has enough capacity.
How much does sprinkler winterization cost?
Blowing out lines before freezing weather typically costs $50–$150 per visit. Many companies bundle it with a spring start-up for about $140–$400 a year.
Is a sprinkler system worth the cost?
For a lawn you plan to keep green through dry summers, usually yes. An automatic system with a smart controller waters on a schedule and skips rainy days, which can cut waste compared with hand watering.
