Irrigation Permit Cost in Conroe, TX (2026)
Lawn irrigation (sprinkler) system permit fees for the City of Conroe, Texas (Montgomery County, north Houston metro), pulled from Ordinance No. 2756-25, Exhibit A - the fee schedule adopted November 13, 2025. Conroe prints named lines for exactly this work under Article X: a new residential irrigation system is a flat $115.00 with inspection included, and a repair or modification to an existing system is $75.00. That is useful, because irrigation is one of those jobs homeowners rarely think needs a permit at all - and in Texas it does. This schedule is also genuinely current: adopted in November 2025, it is one of the freshest verified fee schedules on PermitPrice.
This guide covers: the City of Conroe lawn irrigation system permit fees as printed in Ordinance No. 2756-25, Exhibit A, Article X - a flat $115.00 for a new residential system with inspection included, and $75.00 for a repair or modification to an existing system. Those figures are exact from the adopting ordinance. The residential new-system fee is a flat line; it does not vary with the number of zones, heads, or the value of the installation. Commercial systems are the only tiered irrigation line: $115.00 covers the first 10,000 square feet of coverage, plus $5.00 for each additional 2,000 square feet.
Why this schedule is worth trusting more than most: Ordinance 2756-25 was passed and approved on November 13, 2025, and Section 6 states the provisions are effective immediately upon adoption. That makes it roughly eight months old at extraction - comfortably inside our 24-month currency threshold, and newer than the fee schedules behind most Texas city pages on this site.
Backflow prevention is the item to ask about: a lawn irrigation system tied to the potable water supply requires a backflow prevention assembly under Texas rules, and Exhibit A prints "backflow prevention device installation $75.00 (inspection included)" as its own plumbing line. The ordinance does not state whether that $75.00 is folded into the irrigation permit or charged separately, so this page publishes the irrigation line on its own and discloses the backflow device as a likely companion cost rather than assuming it is bundled. Confirm at application.
This guide does NOT cover: the backflow device fee when charged separately, the cost of the irrigation equipment or its installation labour, licensed-irrigator charges (Texas requires a TCEQ-licensed irrigator for most systems), water and sewer tap or capacity fees (Chapter 70 under separate Ordinance 2759-25), fire-protection fees (Chapter 30, Ordinance 2757-25), Montgomery County or MUD fees, or HOA requirements.
A new residential lawn irrigation system permit in Conroe, TX is a flat $115.00 with the inspection included, printed as a named line in Ordinance No. 2756-25, Exhibit A, Article X, effective November 13, 2025. A repair or modification to an existing system is $75.00. Commercial systems pay $115.00 for the first 10,000 square feet of coverage plus $5.00 per additional 2,000 square feet. A system tied to the potable water supply usually also needs a backflow prevention device, which Conroe prints as a separate $75.00 line - ask whether it is charged in addition. Installing a system without the permit triggers an investigation fee of $2,000.00 or double the permit fee, whichever is greater. Texas adds no state levy.
- Conroe prints named irrigation lines under Article X: a new residential system is a flat $115.00 with inspection included, and a repair or modification to an existing system is $75.00 - so the number is knowable before you call.
- The residential new-system fee is flat. A four-zone yard and a twelve-zone yard both pay $115.00; the number of heads, the pipe run, and the equipment cost are irrelevant to the permit fee.
- Only commercial irrigation is tiered: $115.00 covers the first 10,000 square feet of coverage, then $5.00 for each additional 2,000 square feet. A residential lawn never reaches that structure.
- Backflow prevention is the real variable. A system connected to potable water needs a backflow assembly, and Conroe prints "backflow prevention device installation $75.00 (inspection included)" as its own line. Whether it is billed on top of the $115.00 is a department determination - ask at application.
- Texas requires a TCEQ-licensed irrigator to install most systems. That is a contractor-licensing rule, not a city permit fee, but it is why irrigation is permitted work rather than a weekend project.
- Skipping the permit is expensive out of all proportion to the job: the work-without-permit investigation fee is $2,000.00 or double the permit fee, whichever is greater. On a $115.00 irrigation permit, double is only $230.00, so the $2,000.00 floor governs.
- Source currency is a strength here, not a caveat: Ordinance 2756-25 was adopted November 13, 2025 and took effect immediately, making this one of the freshest verified schedules on PermitPrice. Texas has no statewide permit levy, and Exhibit A prints no technology or application surcharge.
Conroe Irrigation Permit Fee Structure
Every row below is a printed line in Ordinance 2756-25, Exhibit A. The residential irrigation lines are flat with the inspection included; the rows beneath them are the commercial tier, the backflow line that usually accompanies a new system, the penalty structure, and the re-inspection escalation.
| Item | Fee | How It Is Calculated |
|---|---|---|
| New residential irrigation system | $115.00 | Verified flat fee, printed with "inspection included" - same regardless of zone count, head count or equipment cost. |
| Repair or modification to existing system | $75.00 | Verified flat fee, inspection included. Applies to changes to a system that already exists rather than a new install. |
| Commercial irrigation system | $115.00 + $5.00 / 2,000 sq ft | $115.00 covers the first 10,000 sq ft of coverage; $5.00 per additional 2,000 sq ft. The only tiered irrigation line. |
| Backflow prevention device installation | $75.00 (inspection included) | Separate printed plumbing line. A potable-supplied irrigation system needs a backflow assembly; whether this stacks on the irrigation line is a department determination. |
| Re-inspection | $75 / $100 / $150 / $300 | First re-inspection $75.00; second for the same failure $100.00; third $150.00; fourth and each thereafter $300.00. |
| After-hours inspection | $300.00 | Printed for electrical, plumbing, fuel gas and mechanical inspections requested outside normal hours. |
| Work started without a permit | $2,000.00 or 2x, whichever is greater | Investigation fee printed in Exhibit A. On a $115.00 permit, double the fee is $230.00, so the $2,000.00 floor governs. |
| State / city percentage levy | None | Texas has no statewide permit levy; Exhibit A prints no technology, automation, application or credit-card surcharge. |

Worked Examples - Real Irrigation Jobs in Conroe
Every figure below is arithmetic on printed lines from Exhibit A. Where the ordinance is silent - whether the backflow device is billed separately - the example says so instead of assuming a number.
The standard job - a homeowner has a full lawn irrigation system installed for the first time.
- New residential irrigation system: $115.00 (verified flat)
- Inspection: $0.00 (included in the line as printed)
- Texas state levy: $0.00 (none)
- Verified permit cost: $115.00
One printed line, inspection included, no percentage add-ons and no per-zone charge. The one thing to confirm - whether the department also charges the separate $75.00 backflow prevention device line - is disclosed in the limits section below.
The same install, but the department bills the backflow prevention assembly as its own plumbing line - the more conservative scenario a homeowner should budget for.
- New residential irrigation system: $115.00 (verified flat)
- Backflow prevention device installation: $75.00 (verified flat, if charged separately)
- Estimated permit cost if both apply: $190.00
$115.00 + $75.00 = $190.00. Both figures are printed lines; whether they combine is the department's call. This is labelled an estimate precisely because the ordinance does not state that the backflow line stacks on the irrigation permit - it is the honest upper bound for a straightforward new system.
A homeowner adds a zone, relocates heads, or repairs a failed system that is already permitted and installed.
- Repair or modification to existing system: $75.00 (verified flat, inspection included)
- Texas state levy: $0.00 (none)
- Verified permit cost: $75.00
The repair line is $40.00 cheaper than a new install and, like the new-system line, includes the inspection. If the modification also touches the backflow assembly, the separate $75.00 backflow line may apply - ask when you file.
A homeowner or unlicensed installer puts in a system and the city finds out - often at resale or when a later permit is pulled.
- New residential irrigation system: $115.00
- Double the permit fee: $230.00
- Investigation fee floor: $2,000.00 - "whichever is greater" governs
- Verified investigation fee: $2,000.00
Because Exhibit A sets the investigation fee at $2,000.00 or double the permit fee, whichever is greater, the flat $2,000.00 governs on any residential system. On a $115.00 irrigation permit that is roughly 17 times the cost of simply pulling it - the single strongest financial argument for permitting the work.
When This Estimate May Not Apply
The flat $115.00 covers the printed new residential irrigation system line with its inspection. Route your job to the City of Conroe Building Inspections and Permits Department before relying on it if any of the following applies:
- The department also charges the separate backflow prevention device line. This is the main open question on the page. Exhibit A prints the irrigation line and a separate $75.00 backflow prevention device installation line, and does not state whether they combine. A system tied to potable water needs a backflow assembly, so budget for the possibility of $190.00 rather than $115.00.
- Your system is commercial. Commercial irrigation is the only tiered line: $115.00 for the first 10,000 square feet of coverage plus $5.00 per additional 2,000 square feet. A large commercial site can exceed the flat residential figure substantially.
- You are repairing rather than installing. A repair or modification to an existing system is the cheaper $75.00 line, not the $115.00 new-system line.
- The installer is not a licensed irrigator. Texas requires a TCEQ-licensed irrigator for most lawn irrigation systems. That licensing is separate from the city permit fee, but a permit will generally not be issued to an unlicensed installer.
- The inspection fails. Re-inspections run $75.00, then $100.00, $150.00 and $300.00 for repeats of the same failure, and an after-hours inspection is $300.00.
- You need water or sewer capacity work. Water and sewer tap and capacity fees are set in Chapter 70 under separate Ordinance 2759-25 and are not in this schedule. Montgomery County, MUD and HOA requirements are also separate.
- The ordinance has been amended since November 13, 2025. This is a mild caveat rather than a strong one - the schedule is only about eight months old at extraction - but the counter amount should still be confirmed before you file.
The separately billed backflow device, licensed-irrigator charges, commercial tiering above the residential flat fee, re-inspection fees, water and sewer capacity fees, fire-protection fees, Montgomery County and MUD charges, equipment and labour cost, and HOA requirements are all excluded from the $115.00 on this page, and the page-standard disclaimer applies - always verify with the Conroe Building Inspections and Permits Department before budgeting.
Conroe Irrigation Permit Cost vs Other Verified Texas Cities
The useful comparison here is how each city structures the fee, not just the headline number. Conroe and League City both print a residential irrigation line; New Braunfels instead prices irrigation per plumbing outlet, so no single system figure exists there. The table below is labelled peer context only.
| City | How a Residential Irrigation System Is Priced | Published Fee |
|---|---|---|
| Conroe, TX | Named flat line, inspection included (new system) | $115.00 |
| League City, TX | Named residential irrigation permit (flat) | $100.00 |
| New Braunfels, TX | Charged per plumbing "irrigation outlet", not per system | $2.00 per outlet |
Scope note: Conroe's $115.00 is a printed new-system line with the inspection included and no per-zone charge. League City prints a flat $100.00 residential irrigation permit ($100.00 plus $25.00 per zone for commercial). New Braunfels does not price irrigation as a system at all - its plumbing schedule charges $2.00 per irrigation outlet, so a system's total there depends entirely on outlet count and is not a like-for-like number. These are labelled peer figures for context, not a like-for-like comparison. Confirm current figures with each department.
