This article is brought to you by the team at TLC — Maryland’s trusted experts in erosion control, foundation drainage, and long-term yard protection.
If you’re thinking about adding sprinkler coverage to new parts of your yard, the first question is always:
“How much does it cost to add a zone for the front, back, or side lawn?”
Good question. And the answer depends on a few key things: size, access, water pressure, and where your main line and valve box are located.
Here’s what we see across Maryland in 2026.
Average Add-On Costs by Zone Location
| Zone Location | Typical Add-On Cost |
| Front Yard | $1,200 – $1,800 |
| Back Yard | $1,400 – $2,200 |
| Side Yard | $900 – $1,400 |
| Garden/Drip Zone | $800 – $1,200 |
These prices assume you’re tying into an existing system with a controller, valve manifold, and decent water pressure (50+ PSI). If we need to upgrade the controller or replace valves, we’ll build that into your quote.
What Drives the Cost?
1. Access to the Area
Are we working on open lawn where we can trench easily? Or do we need to work around trees, patios, fences, or utility lines? Narrow side yards, tight backyard gates, or steep slopes all increase complexity.
2. Distance from the Manifold
The farther we have to run pipe from the valve manifold, the more time and materials the job takes. We’ll measure the path and factor in what’s in the way.
3. Size and Shape of the Area
A simple rectangle of grass is faster to cover than a curvy flower bed with corners and obstacles. More coverage usually means more heads, more pipe, and more trenching.
4. Type of Zone
Turf zones typically use rotors or sprays. Garden zones often use dripline or bubblers. Drip is more precise, but takes longer to install properly.
5. Controller Compatibility
If your controller only supports 6 zones and you’re already using all 6, we may need to install a new controller or expansion module.
6. Water Pressure and Flow
If your system is already near capacity, we’ll check your PSI and gallons per minute to make sure we can add a zone without weakening performance.
What Does a Zone Include?
A typical sprinkler zone add-on includes: – New valve tied into the manifold (and box if needed) – Poly pipe for supply line and lateral lines – Sprinkler heads (rotors, sprays, or drip) – Trenching, backfill, and compaction – Wire to the controller (if it’s not already wired) – Pressure test and system flush
We include all parts and labor in our estimates. No hidden costs.
TLC Example: Side Yard Add-On in Annapolis
A homeowner wanted to irrigate a narrow strip of lawn beside the driveway. It was only 4 feet wide, but 70 feet long, and they were tired of dragging a hose.
We installed: – 3 spray heads for 400 sq ft of turf – 80 ft of pipe under mulch and lawn – A new valve tied into the existing manifold
Cost: $1,150
Time: 1 day
Result: Even green coverage and no overspray on the sidewalk
The homeowner told us, “I didn’t think it was worth it for such a small area, but now it looks better than the rest of the lawn.”
TLC Example: Back Lawn Zone in Crofton
A backyard had been skipped in the original install. The homeowners were tired of dragging hoses and spot-watering. We designed a zone to fit the space and work with their lawn shape.
We installed: – 5 rotor heads for 1,200 sq ft of grass – 120 ft of pipe – One new valve and a zone expansion module
Cost: $1,950
Time: 2 days
Result: Full-yard coverage and easy app-based scheduling
When We Recommend Separate Zones
You don’t always want to lump everything into one big zone. Here’s when we suggest separate zones:
- Front vs back: They get different sun, different soil, and different watering needs.
- Sun vs shade: Shaded areas need less water.
- Turf vs beds: Grass needs different heads and water rates than drip for gardens.
- Small strips or medians: A side yard often does better with its own timing.
We walk every zone and help you plan the right way.
Can I DIY a Sprinkler Zone Add-On?
If you’re handy, you can certainly try—but it depends on your system: – Do you know your PSI and GPM? – Can you locate and tap the existing main line? – Do you have valve box access? – Will your controller handle more zones?
We’ve helped dozens of homeowners who started DIY and called us when they hit the wiring or water pressure snag. We’re happy to take over or walk you through it.
Controller Tip: Smart Upgrades
If your controller is more than 10 years old, now is a great time to upgrade to a smart Wi-Fi unit: – Program zones by app – Get weather-based adjustments – Manage watering while you’re on vacation – Save water with cycle-and-soak schedules
We install Hunter Hydrawise, Rain Bird ESP-Me3, and Rachio systems.
Controller upgrade cost: $350 – $650 installed
How We Price Zones at TLC
We price each add-on based on: – Distance and obstacles – Soil conditions and hand-dig zones – Number of heads – Controller access – Water source pressure
We don’t price by square foot because not all square feet are equal. A tight strip between sidewalk and curb takes more time and precision than a wide backyard field.
Common Add-On Requests
- New side lawn after a patio install
- Garden beds added later
- Play areas that weren’t originally irrigated
- Small front or corner lawn not covered in the main plan
- Dog run, tree line, or pool landscaping zones
We match heads to plant type, sun, and water needs. It’s never a one-size-fits-all job.
What to Expect During Installation
- We mark all lines and utilities.
- We hand-dig around roots, wires, or tight spaces.
- We trench, install pipe, and set heads.
- We tie into the manifold and test pressure.
- We wire the valve to the controller.
- We backfill, compact, and level the soil.
- We test the zone and fine-tune spray.
Most add-ons take 1–2 days. You don’t need to be home all day, but we walk through everything with you before and after.
