Waco plumbing permits: a published no-permit list, and no fee to register as a contractor

Waco publishes two things we have not found stated this plainly anywhere else in Texas. The first is a list of work that needs no permit, written with the conditions attached rather than left to a reader to guess. The second is a single sentence that settles a question three other cities leave in conflict: Waco requires plumbing contractors to register with the city, and it says in its own words that there is no fee for it.

Neither sentence ranks. On a search for Waco’s plumbing permit requirements read on 6 October 2026, a permit template site held the top two results, followed by the city’s online code, the state statute and two old bills, with no City of Waco page in the set.

Who issues the permit

Inspection Services, a division of Development Services, at the Dr. Mae Jackson Development Center, 401 Franklin Ave.

The number is (254) 750-5612 and the division answers email at permits@wacotx.gov. Hours are Monday to Friday, 8 a.m. to 5 p.m. Applications, payments and inspection requests run through the city’s Citizen Self Service portal.

One current caveat, from the division’s own page: “The launch of the City’s new permitting software has been delayed while our software vendor works to resolve issues identified during the transfer of information from the current system to the new system.” Everything below describes the system in use. If you are reading this during the changeover, expect the portal to move.

Inside the Waco city limits, every plumbing permit comes from Inspection Services. The statewide rules sit on Texas plumbing permits: what needs one, and who can pull it, and the license-verified plumbers we list for the county are on McLennan County plumbing services.

What needs a permit, and what does not

Waco answers this with two lists: work that needs a permit, and work that does not. Most Texas cities give you one sentence about repairs and alterations and leave you to place your own job.

On the permit side, plumbing appears three times, each with its own permit type. Water heaters: “Installing a water heater requires a Residential Plumbing permit.” Water or wastewater: the entry opens “This includes all plumbing work performed within the property line”, and the trigger is the next line, “A Residential Plumbing permit is needed to address issues with the pipe system or to add new fixtures, such as adding a new sink in a laundry room.” Gas: “For work on a gas service line from the meter to the house, gas piping in the house, gas connections, or similar work, apply for a gas permit.”

Then the no-permit list, and this is the part worth the trip. Quoted whole, because the conditions inside it are the whole content:

Minor plumbing work, including repairing minor leaks, as long as the removal, replacement, or relocation of piping is not required; unclogging drains and sewers; replacing toilets, faucets, and other fixtures in the same location without altering the pipes

Three jobs, two conditions, and the conditions are where people get caught.

“As long as the removal, replacement, or relocation of piping is not required.” A leak you fix by tightening a connection or swapping a supply line is on the no-permit side. The same leak, fixed by cutting out a length of pipe, is not.

“In the same location without altering the pipes.” Replacing a toilet is on the list. Moving the toilet eighteen inches is not, even though it is still “replacing a toilet” in any ordinary sense of the phrase.

The city attaches its own caveat to that list: “Other exceptions found in IRC R.105 may apply to the permitting requirement.” So the list is where Waco starts, not where the question ends.

Waco also states its fixture rule twice, from both directions, which removes the usual ambiguity: adding a sink needs a permit, and “Changing out fixtures, such as replacing a toilet, does not require a permit.”

That maps onto state law more closely than most city lists do. Section 1301.551(c) of the Texas Occupations Code tells a city that adopts a plumbing ordinance it must require a permit for plumbing “other than the repairing of leaks, the replacement of lavatory or kitchen faucets, the replacement of ballcocks or water control valves, the replacement of garbage disposals, or the replacement of water closets.” Waco has written those jobs into its own list, in its own words, and attached a condition the statute does not impose: the pipes must not move. A city is allowed to do that, because the same subsection says the municipality “may prescribe the terms on which the permit is issued”. Nine cities’ versions of that line, side by side, are on which small plumbing jobs need a permit in Texas.

And the statewide answer on the one job people ask about most, with the cities that disagree about it, is on do you need a permit to replace a water heater in Texas. Waco is on the clear side of that split: a water heater needs a Residential Plumbing permit, and the city says so in a sentence with no conditions in it.

Can a homeowner pull a plumbing permit? Yes, on a homesteaded property, and the city attaches that condition to every trade permit

Waco repeats the same condition on entry after entry, in the same words each time. From the water heater entry: this permit “requires a licensed plumber, unless a homestead owner is doing the work themselves on their homesteaded property”. From the gas entry: “This work requires a licensed plumber, unless a homestead owner is doing the work themselves on their homesteaded property.” And from the water and wastewater entry: “Apply for a Residential Plumbing permit, which requires a licensed plumber, unless a homestead owner is doing the work themselves on their homesteaded property.”

And once as a general rule:

Electrical, plumbing, mechanical, and irrigation permits must be pulled by a licensed trade contractor unless you are permitting and completing the work yourself on your homesteaded property.

Note what that sentence requires of you, because it is tighter than it first reads. You must be both permitting and completing the work. A homeowner who pulls the permit and then has somebody else do the work is outside it. Dallas and Arlington write a similar no-assistance condition into their homeowner forms; Waco builds it into the permission itself.

What Waco does publish, in a document most people will never open, is one more condition. Its Homestead Owner submission checklist “Applies to electrical, plumbing, mechanical, and irrigation permits submitted by a homestead owner (not a licensed trade contractor)”, and asks for one document: a “Copy of the homestead owner’s driver’s license”. The condition under it is the part to read twice:

The name and address must match the homestead owner information on the McLennan County Appraisal District

So the appraisal district does gate this, as a matching check rather than a filing. If the license in your wallet does not carry the name and address MCAD holds for the property, the permit stops there. A recent move, a maiden name, or a license you never got around to updating is enough to fail it. That is the single most useful thing on this page and it is on none of the pages that rank.

What Waco does not publish is a homestead affidavit of the kind Irving and Garland rely on, a notarized form, or a cap on how many homeowner permits you may take in a year of the kind Austin imposes. We read the checklist for all three.

The state side is one sentence. Section 1301.051: “A property owner is not required to be licensed under this chapter to perform plumbing in the property owner’s homestead.” That exempts you from needing a license, not from the permit. Who is legally allowed to touch your pipes in Texas has the rest of it, including what the word homestead does and does not reach.

Registration: required, and free, and the city says so

From Waco’s residential permit page, repeated word for word on its commercial one:

Before building permits can be issued for plumbing, electrical, and mechanical work, the contractor must be registered with our office. Please note that there is no registration fee for contractors.

And the companion sentence: “Contractors must show proof of their state licensing for mechanical, plumbing, electrical, and irrigation work.”

Section 1301.551 lets a city do exactly this and bars it from charging. Subsection (h) permits a city to require a plumbing contractor to register with it. Subsection (g) is the limit: a responsible master plumber, plumbing contractor “or other person who is required to obtain a permit under this section is not required to pay a plumbing registration fee or administrative fee in a municipality or any other political subdivision.”

Waco has put both halves on its own page. That matters because three cities we have written up have not. Fort Worth publishes a $168.75 contractor registration with no exception on the page and an ordinance that exempts state-licensed plumbers by name. Arlington has the same shape of problem. And Mesquite, in the same batch as this page, contradicts itself: its FAQ says plumbing contractors pay nothing for the city credential and its commercial fee schedule prices that credential at $125.00. Plano resolves it the way Waco does, in the city’s own words. Waco’s version is the clearest of the set.

Registration itself is an email. The city asks for a Master Plumbing License, the driver’s license of the master holder, the cell phone number of the master holder, and a “Certificate of Insurance with the City of Waco listed as the certificate holder”, sent to permits@wacotx.gov. The certificate-holder detail is specific and easy to get wrong: a generic certificate naming nobody will not do.

One more rule that shapes who files what: “Sub-contractors (electrical, plumbing, and heating/air conditioning) must be licensed and are required to permit their own work.” On a job with a general contractor, your plumber pulls the plumbing permit. It does not ride on the builder’s.

Fees

Waco prices a plumbing permit in parts, and publishes no single number for a job.

These are the plumbing lines a residential job is most likely to draw, from the city’s fee page, which carries no date of any kind. We checked for one specifically: no effective date, no fiscal year, no revision date, no ordinance number. So read these as what Waco published on 6 October 2026, confirmed at the counter before you budget. The full Plumbing & Lawn Sprinkler section runs to eighteen lines and also prices commercial review, irrigation review, an appeals filing, an ETJ sprinkler trip fee, and a scope-of-work change at $60 plus 10% of the original permit fee.

Line	Fee
Plumbing & Irrigation Administration Fee	$60
Technology Fee – Plumbing & Irrigation	$15
For Each Plumbing Fixture, Trap, Grease & Sand Trap, Hot Water Heater, & Gas Fired Appliance	$8
For Each House Sewer, Water, & Gas Service (Yard Lines Installation or Repair)	$20 per line, per 100 feet
For Each Sump Pump, Grinder Pump, or Lift Station	$10
For Each Discharge Line & Roof Drain	$10
For Each Boiler	$50
For the First Vacuum Breaker or Back Flow Protective Device Installed Subsequent to the Installation of a Lawn Sprinkler System	$40
Each Additional Backflow Protective Device	$10
Contractor Transfer Fee	$60
Permit Renewal	50% of original permit fee or $60 minimum
Occupied & Down Reinspection / Not Ready	$125

A water heater replacement therefore draws the administration fee, the technology fee and one $8 appliance line. We are not printing a total, because the city does not state whether the administration and technology fees are charged once per permit, and three lines added up by us is not the city’s price.

The structure still tells you something. The fixed lines dwarf the per-fixture line: at $8 a fixture, the difference between permitting one fixture and five is $32. If you are weighing a bathroom in stages, the arithmetic argues for doing it on one permit.

Two lines are worth planning around.

“Occupied & Down Reinspection / Not Ready” is $125. It is a charge for the inspector arriving to find the work not ready, and at $125 it dwarfs the per-fixture and per-service lines an ordinary job draws: fifteen fixtures’ worth of permit for one wasted trip. In an occupied house, where the city also requires somebody to be there, that is a real risk and an avoidable one.

Starting without the permit doubles everything. The schedule’s own words: “In case any work, for which a permit is required by this chapter, is started prior to obtaining said permit, the fees above shall be doubled.” The statutory and enforcement side of that is on what happens if you skip a plumbing permit in Texas.

For comparison, Mesquite charges one flat $75 with the water heater written into the line, and McAllen prices a base fee plus $24 for a water heater. What a plumber charges in Texas covers the labor beside any of them.

The re-inspection fee: two city pages, two answers

Waco’s fee page prices three failures:

Line	Fee
1st Failed Reinspection	$55
2nd Failed Reinspection	$100
3rd+ Failed Reinspection	$150

Waco’s Inspection Procedures page says this:

A reinspection fee applies if a third inspection (second reinspection) is required. Any reinspection fees must be paid before scheduling the third site visit.

Those are two City of Waco pages, read on the same day, disagreeing about when you start paying. The fee schedule prices the first failed re-inspection. The procedures page says the fee starts at the second. Both readings are the city’s own text and we cannot reconcile them from anything either page says.

If a failed inspection is about to cost you money, ask Inspection Services on (254) 750-5612 which of its two pages is in force before you schedule. We would rather tell you there is a question here than publish a number that might be wrong by $55.

Inspections

Requested online by 4 p.m. the day before, and somebody has to be home.

The rule is flat: “All inspections must be requested online by 4 p.m. the day before the inspection is needed.” Miss it and “After 4 p.m., the inspection request will be pushed back an additional day.”

For a house you live in: “For occupied residential dwellings, contractor or property owner is required to be present during inspections.”

And one timing trap for paperwork rather than pipe: documents that need approval before an inspection can be scheduled “will require a minimum of 24 hours for the workflow to be changed or approved”. On a tight week, that is two days of lead time, not one.

Code cycle

Waco states it “has adopted the following codes as of January 1, 2026, as the Minimum Building Standards Codes of the City of Waco”. The plumbing one is listed as “International Plumbing Code, 2024 edition, including appendix E”.

That puts Waco in the newest cycle, alongside Plano, and unlike almost every city we have written up it attaches a date to the adoption. The energy code is the odd one out at the 2018 edition.

What this page does not claim

When a re-inspection fee starts. Two city pages disagree and the question is live.

That the fee figures are current-year. There is no date on the schedule to report, and saying so is more useful than implying one.

A total for a water heater permit. The components are above; the city publishes no combined figure.

Anything from Chapter 6 of the Code of Ordinances or the 2024 IPC itself. Everything here comes from the city’s permit, registration, fee, procedures and adopted-codes pages, which is what a Waco homeowner is actually handed. The ordinance behind them is wider than what they print.

Sources, and when we read them

Every figure on this page comes from one of the documents below, each published by the body that sets, measures or administers the thing it describes. We record the document’s own date and the date we read it, because published pages change without notice.
