Water Heater Permit Cost in Conroe, TX (2026)

Water heater replacement 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 a named line for exactly this job: water heater replacement - $75.00, inspection included. That matters more than it sounds. Water heater swaps are one of the most common residential permits in America and one of the hardest to price in advance, because most cities bury them inside a plumbing permit whose cost depends on fixture counts. Conroe instead prints a flat line with the inspection folded in, so the number is knowable before you call anyone. This schedule is also genuinely current - adopted in November 2025, it is one of the freshest verified fee schedules on PermitPrice.

What This Guide Covers - and What It Does Not

This guide covers: the City of Conroe water heater replacement permit fee as printed in Ordinance No. 2756-25, Exhibit A - a flat $75.00 with inspection included. That figure is exact from the adopting ordinance. It does not vary with tank capacity, fuel type as printed, equipment cost, or the value of the installation, because the schedule prints it as a named flat line rather than a valuation tier or a per-fixture calculation.

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.

One open question, stated plainly: Exhibit A prints the flat "water heater replacement $75.00 (inspection included)" in its list of standalone plumbing flat fees, and separately prints a general Plumbing Base Permit Fee of $75.00 under Article IV with its own per-inspection charges. The ordinance does not state whether the flat water-heater line stands alone or sits on top of the Article IV base fee. This page publishes $75.00, because the flat line is printed as a complete item with the inspection included - but if the department stacks the base permit fee, your cost would be $150.00. Ask when you apply.

Gas-fired units may involve a second trade: a gas water heater can touch the fuel gas article, which carries its own $75.00 base permit fee plus per-inspection charges, and Exhibit A separately prints a "gas test on existing service" at $75.00. Whether your specific replacement draws a fuel gas permit in addition to the plumbing line is a department determination. No combined figure is asserted here.

This guide does NOT cover: tankless conversions that require new gas line sizing or electrical service work (electrical is a separate article with a $75.00 base permit fee), water heater equipment or labour cost, 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.

Key Takeaways
  • Conroe prints a named "water heater replacement" line at a flat $75.00 with inspection included - unusual and useful, because most cities route a water heater swap through a general plumbing permit whose cost depends on fixture counts you cannot predict in advance.
  • The fee is flat. A 40-gallon tank swap and a 75-gallon high-efficiency unit both pay $75.00, and the price of the equipment is irrelevant to the permit fee.
  • The inspection is inside the $75.00 - the ordinance says so on the line itself. That is the difference between Conroe's flat plumbing lines and its per-square-foot residential building permit, where inspections are priced by work area.
  • 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 $75.00 water heater permit, that is a $2,000.00 exposure - roughly 27 times the permit.
  • Failed inspections escalate: $75.00 for the first re-inspection, $100.00 for a second on the same failure, $150.00 for a third, and $300.00 for the fourth and each one after. A single re-inspection doubles the cost of the job's permitting.
  • The same Exhibit A prints several neighbouring plumbing flat fees worth knowing: backflow prevention device installation $75.00, building sewer or sewer line replacement $75.00, interior water line re-pipe or water line replacement $100.00, and grease trap or sand-oil separator installation $100.00.
  • 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 Water Heater Permit Fee Structure

Every row below is a printed line in Ordinance 2756-25, Exhibit A. The water heater line is flat with the inspection included; the rows beneath it are the neighbouring plumbing flat fees, the penalty structure, and the one item the ordinance leaves open.

Item Fee How It Is Calculated
Water heater replacement $75.00 Verified flat fee, printed with "inspection included" - same at any tank size, fuel type or equipment cost.
Plumbing base permit fee (Article IV) $75.00 - stacking on the flat line unstated The general plumbing base fee, with inspections priced by work area ($15.00 each up to 1,000 sq ft). The ordinance does not say whether it stacks on the flat water-heater line.
Fuel gas base permit fee (Article V) $75.00 - applicability project-specific May apply to a gas-fired replacement. Whether your job draws it is a department determination.
Gas test on existing service $75.00 (inspection included) Separate printed flat line. Relevant if the gas service has to be tested as part of the swap.
Backflow prevention device installation $75.00 (inspection included) Neighbouring plumbing flat line - shown for context on related work.
Interior water line re-pipe or water line replacement $100.00 (inspection included) Applies if the swap includes re-piping rather than a straight change-out.
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.
Work started without a permit $2,000.00 or 2x, whichever is greater Investigation fee printed in Exhibit A. On a $75.00 permit, double the fee is $150.00, 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 Water Heater Jobs in Conroe

Every figure below is arithmetic on printed lines from Exhibit A. Where the ordinance is silent - whether the plumbing base fee stacks, whether a gas permit is drawn - the example says so instead of assuming a number.

Example 1: Straight 50-gallon electric tank change-out

The most common version of this job - old tank out, new tank in, same location, same connections.

  • Water heater replacement: $75.00 (verified flat)
  • Inspection: $0.00 (included in the line as printed)
  • Texas state levy: $0.00 (none)
  • Verified permit cost: $75.00

One printed line, inspection included, no percentage add-ons. This is as clean as a residential permit calculation gets. The open question - whether the department also charges the Article IV plumbing base permit fee - is disclosed in the limits section below.

Example 2: 75-gallon high-efficiency unit, three times the equipment cost

A homeowner upgrades to a much larger, much more expensive unit. The permit fee does not notice.

  • Water heater replacement: $75.00 (verified flat - unchanged)
  • Capacity or equipment-cost adjustment: $0.00 (no tier exists in the ordinance)
  • Verified permit cost: $75.00

Worth noting because Conroe does use valuation elsewhere - the ICC Building Valuation Table governs commercial work and non-dwelling residential structures - and prices residential dwelling permits at $0.64/sq ft. The water heater line escapes both treatments.

Example 3: Replacement that fails its first inspection

The inspector finds a problem - improper venting, a missing expansion tank, a bad T&P discharge line - and returns.

  • Water heater replacement: $75.00 (verified flat, first inspection included)
  • First re-inspection: $75.00 (verified flat)
  • Verified permit cost: $150.00

$75.00 + $75.00 = $150.00. A single failed inspection doubles the permitting cost of the job. A second failure on the same issue adds $100.00 more, a third $150.00, and a fourth and beyond $300.00 each.

Example 4: Water heater replaced without a permit, then caught

A homeowner or unlicensed handyman swaps the unit and the city finds out - often when the house is sold or when a later permit is pulled.

  • Water heater replacement: $75.00
  • Double the permit fee: $150.00
  • 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 small job. On a $75.00 water heater permit that is roughly 27 times the cost of simply pulling it - the single strongest financial argument for permitting a change-out in Conroe.

When This Estimate May Not Apply

The flat $75.00 covers the printed water heater replacement 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 Article IV plumbing base permit fee. This is the main open question on the page. Exhibit A prints the flat water heater line as a complete item with inspection included, and separately prints a $75.00 plumbing base permit fee. The ordinance does not state whether they stack. If they do, your cost is $150.00 rather than $75.00.
  • Your replacement is gas-fired and draws a fuel gas permit. The fuel gas article carries its own $75.00 base permit fee plus per-inspection charges, and a separate "gas test on existing service" line at $75.00 exists. Whether either applies to your swap is a department determination and is not asserted here.
  • You are converting to tankless. A tankless conversion commonly requires resized gas piping, new venting, or a dedicated electrical circuit. Those touch other articles - the electrical article also carries a $75.00 base permit fee - and are not covered by the water heater replacement line.
  • The job includes re-piping. Interior water line re-pipe or water line replacement is its own $100.00 printed line, separate from the $75.00 replacement fee.
  • 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 unresolved plumbing-base-fee stacking question, fuel gas and electrical permits, tankless conversion work, re-piping, re-inspection fees, water and sewer capacity fees, fire-protection fees, Montgomery County and MUD charges, equipment cost and HOA requirements are all excluded from the $75.00 on this page, and the page-standard disclaimer applies - always verify with the Conroe Building Inspections and Permits Department before budgeting.

Conroe Water Heater Permit Cost vs Other Verified Texas Cities

The useful comparison here is not really price - it is whether a city prints a water heater line at all. Most do not, which is why a homeowner cannot get a straight answer before calling. The table below is labelled peer context only.

City How a Water Heater Swap Is Priced Published Fee
Conroe, TX Named flat line, inspection included $75.00
League City, TX No named line; general plumbing permit, $59.00 base + $5.00 per fixture Not published as a line
Beaumont, TX No named line; plumbing permit $15.00 per fixture, $70.00 minimum Not published as a line

Scope note: Conroe's $75.00 is a printed water-heater-specific line with the inspection included. League City and Beaumont print no water heater line at all on their verified schedules, so no water heater figure is published for them here - only the general plumbing permit structure that a swap would fall under. That is a deliberate refusal to guess, not an omission. These are labelled peer figures for context, not a like-for-like comparison. Confirm current figures with each department.

Frequently Asked Questions

A water heater replacement permit is a flat $75.00 with the inspection included, printed as a named line in Ordinance No. 2756-25, Exhibit A, effective November 13, 2025. It does not vary with tank capacity or equipment cost. One caveat: the ordinance separately prints a $75.00 plumbing base permit fee and does not state whether it stacks on the flat line, so confirm at application.
The city prints a permit fee specifically for water heater replacement, and Exhibit A sets a work-without-permit investigation fee of $2,000.00 or double the permit fee, whichever is greater. Whether your particular job requires a permit is a determination for the Building Inspections and Permits Department, but the fee schedule clearly contemplates that the work is permitted - and the cost of not permitting it dwarfs the $75.00.
No. The line is flat, so a 40-gallon replacement and a 75-gallon high-efficiency unit both pay $75.00. This is notable because Conroe uses valuation elsewhere - the ICC Building Valuation Table governs commercial work and non-dwelling residential structures - and prices residential dwelling permits at $0.64/sq ft plus $0.32/sq ft plan review. Water heater replacement escapes both.
Yes - the printed line says "inspection included". That is a meaningful distinction in Conroe, because the city's general trade permits price inspections separately by work area ($15.00 each up to 1,000 sq ft, escalating with size). A re-inspection after a failure is not included: the first is $75.00, then $100.00, $150.00, and $300.00 for repeats of the same failure.
The printed water heater replacement line does not distinguish fuel type, so $75.00 is the figure it gives. However, a gas replacement can touch the fuel gas article, which carries its own $75.00 base permit fee plus per-inspection charges, and Exhibit A separately prints a "gas test on existing service" at $75.00 with inspection included. Whether either applies to your job is a department determination, so no combined total is asserted here.
Exhibit A prints no tankless-specific line, so no tankless figure is published here. A conversion commonly requires resized gas piping, new venting, or a dedicated electrical circuit - and the electrical article carries its own $75.00 base permit fee with inspections priced by work area. Treat a tankless conversion as a multi-trade job and ask the department to scope it before you budget.
Exhibit A prints a work-without-permit investigation fee of $2,000.00 or double the permit fee, whichever is greater. Because double a $75.00 permit is only $150.00, the $2,000.00 floor governs on a water heater - roughly 27 times what the permit would have cost. This most often surfaces at resale or when a later permit is pulled on the same property.
Unusually current for this site. Ordinance No. 2756-25 was passed and approved on November 13, 2025, and Section 6 states the provisions are effective immediately upon adoption - roughly eight months before the July 2026 extraction, well inside our 24-month currency threshold. The figures were read from the text layer of the signed ordinance PDF hosted by the city. One process note: the Municode-hosted version of Appendix A returned an automated-access error and was not used; no conflict was observed, because the city PDF is the adopting instrument Municode codifies.

Always verify current water heater permit fees directly with the City of Conroe Building Inspections and Permits Department before budgeting or filing. The figures on this page come from Ordinance No. 2756-25, Exhibit A, effective November 13, 2025. The $75.00 is the printed water heater replacement line with its inspection included. Ask specifically whether the Article IV plumbing base permit fee is charged in addition to that line, whether a gas-fired replacement draws a separate fuel gas permit, and how a tankless conversion is scoped - the ordinance does not resolve any of those.
Disclaimer: All fee information on PermitPrice is for informational purposes only and is not an official permit quotation. Actual permit fees are determined by the City of Conroe Building Inspections and Permits Department at the time of application. The $75.00 water heater replacement line (inspection included), the $75.00 plumbing, fuel gas and electrical base permit fees, the $75.00 backflow prevention device and gas-test lines, the $100.00 interior water line re-pipe line, the $75/$100/$150/$300 re-inspection escalation, the $300.00 after-hours inspection and the $2,000.00-or-double work-without-permit investigation fee are exact from Ordinance No. 2756-25, Exhibit A; the $150.00 and $2,000.00 example totals are arithmetic on those printed inputs. The ordinance does not state whether the Article IV plumbing base permit fee stacks on the flat water heater line - if it does, the cost would be $150.00 rather than $75.00, and that limitation is disclosed on this page rather than resolved. No tankless-specific line is printed, so no tankless figure is published. Fuel gas and electrical permits, tankless conversion work, re-piping, water and sewer tap and capacity fees (Chapter 70, Ordinance 2759-25), fire-protection fees (Chapter 30, Ordinance 2757-25), Montgomery County and MUD fees, equipment and labour cost, and HOA requirements are all excluded. Verify all fees directly with the department before filing.
