How Much to Charge for Irrigation System Installation
Irrigation installation is typically priced per zone at $600–$1,200 per zone installed, putting a standard 4–6 zone residential system at roughly $3,000–$6,500 including controller and backflow. Trenching runs $2–$5 per linear foot, boring under a driveway or walkway $8–$20 per foot, backflow devices $150–$500 plus permit and inspection at cost, and most contractors hold a job minimum around $2,000.

Measure pressure before you price anything
Static pressure and meter size determine how many heads a zone can actually support, which determines the zone count, which ends up being most of your price.
Two yards of identical size can need four zones or seven. Guess at this and you either lose the bid or build a system that just doesn’t cover the yard.
Walk for the crossings
Driveways, walkways, patios, and tree roots all mean boring or hand-digging. They’re nearly invisible on an aerial view, and they’re exactly where routine jobs turn expensive — walk the property and mark every crossing before you quote.
Sell the smart controller
A weather-based controller saves real water and often qualifies for a utility rebate. Quote it as an option on every job — it’s a small upgrade with good margin, an easy yes for most customers, and it cuts down on the callbacks about over- and under-watering.
Quote winterization at install
The system needs blowing out every fall, forever. Putting the annual service on the install proposal turns a one-time build into a customer you see twice a year, which is really the difference between an installation business and an installation-plus-service business.
Don’t compete on head count
A cheaper bid usually has fewer zones and more heads crammed into each one, which means weak coverage at the ends of the run. State your zone count and the pressure it’s designed around — it’s a spec the customer can go ask the other bidder about.
Frequently asked questions
Why price per zone instead of per head?
Because the zone is what drives cost — a valve, wire run, and controller station — while head count varies within it. Quote per zone as the base and adjust for head count and type, so a zone with eighteen spray heads isn't priced like one with six rotors.
How much does boring under hardscape add?
$8–$20 per foot, and it's slow, awkward work. A driveway crossing can add hundreds to a job that otherwise looks routine — walk the property and identify every crossing before quoting, because they're easy to miss on a satellite image.
Should I include the backflow permit?
Pass it through at cost with the jurisdiction named, and never skip it. Backflow prevention protects the potable water supply, it's code almost everywhere, and an uninspected installation is a liability with your name on it.
How does static pressure affect the price?
Directly. Low pressure or a small meter means more zones to cover the same area — more valves, more wire, more controller stations. Measuring pressure first is what separates an engineered quote from a guess, and it's why two identical-looking yards can differ by a thousand dollars.
