Plano plumbing permits: where the homeowner rule actually lives

Plano has published its homeowner permit rule for years. We said otherwise, and we were wrong: our earlier research read the city’s FAQ pages, and the rule is not there. It is in a counter handout that has carried it since at least 2016, and since 1 August 2025 it is in the enacted ordinance too, word for word the same. This page quotes both.

Everything below is from the city’s own ordinances, handouts and pages. Where a document carries a date we print it. Several of Plano’s carry none, and we say so.

Who issues the permit

The City of Plano’s Building Inspections Department issues residential plumbing permits.

The counter is at 1520 K Avenue, Suite 140, Plano, TX 75074, inside the Plano Municipal Center. The department’s number is 972-941-7140. For email, the address the city prints on its permit paperwork is buildingpermits@plano.gov: it is in the header of the Residential Permit Application and in the footer of A Customer’s Guide to the Building Permit Process, revised 10/8/2024. The brochure the city currently links for telephone inspections gives the hours as 8AM to 5PM: “During our normal business hours, Monday through Friday,” it says, “you can still call Permitting Services at 972-941-7144 for assistance with other matters”.

Online permitting runs through eTRAKiT, which the city describes as the place to “Apply for building permits, search projects and contractors, and schedule inspections.” The city also publishes paper application forms.

Plano sits in two counties. The city’s own “Plano, TX Profile: Government”, updated January 2025, has a County Government section listing Collin County and Denton County, each with its county judge and four elected commissioners. Most of the city is in Collin County and the western edge is in Denton County. Either way an address inside the city limits is a city matter start to finish. Outside a city the picture is different: Texas counties have no general authority to require residential plumbing permits in unincorporated areas, and the narrow county authority that does exist is opt-in. We set that out with the statute and the county sources on Texas plumbing permits, and this page does not restate it.

Plano adopted the 2024 International Plumbing Code by Ordinance No. 2025-6-7 and the 2024 International Residential Code by Ordinance No. 2025-6-15, and the city’s codes page states that the “2024 Codes were adopted and went into effect on August 1, 2025”. That puts Plano a cycle ahead of Dallas, which works from amendments to the 2021 International Plumbing Code.

Can a homeowner pull a plumbing permit? Yes, and Plano has said so twice

The counter handout has said it since at least 2016. The 2024 code adoption put the same sentence in the ordinance.

Start with the handout, because it is the older of the two. The Building Inspections Information Sheet, marked FM624MP019 REV. 04/11/12 with “8/11/2016 Revised” on its face, sets out the residential rule in one paragraph:

“Residential permits require application submittal by registered, licensed (if appl.) contractors. Homeowners may obtain permits to do work at their residence without being registered and list themselves as a general contractor when assuming responsibility of that permit.”

Then the ordinance. Section R105.3, as Plano amends it in Ordinance No. 2025-6-15, starts from the opposite default: “To obtain a permit, the applicant shall be registered as a contractor.” After the registration terms it adds one line.

“Exception: Homeowners may obtain permits to do work at their residence without being registered.”

Word for word the same exception, nine years apart. What the 1 August 2025 adoption changed is not the rule but the instrument. A handout that disclaims itself, in its own footer, as “for informational purposes only and should not be relied on in place of official regulations and/or policies” became enacted text a homeowner can cite at the counter. That is a real improvement. It is not a new rule.

Worth saying why we missed it, because it is an easy mistake to repeat. Our earlier pass read Plano’s FAQ pages, where the answer is not. It was in a PDF handout and, later, in an ordinance exhibit. When a city’s FAQ is silent on who may pull a permit, the handouts and the adopting ordinance are the next two places to look, in that order.

Neither version attaches a homestead certificate, an owner-occupancy affidavit, a one-permit-per-year limit, or a promise to work alone. Dallas asks for a homestead exemption certificate and San Antonio for a sworn affidavit. Plano publishes neither. The handout adds the one practical condition either document states: a homeowner who takes the permit lists themselves as the general contractor, and takes on what that means.

Plano’s own contractor selection handout says what that costs you: “Be especially wary of contractors suggesting you obtain permits for their work. If you obtain the permit for a contractor, then you will be responsible for their work.”

Holding the permit is not the same as being allowed to do the plumbing. That is state law, and it is covered in who can legally do plumbing in Texas.

What needs a permit, and Plano’s own exempt list

Plano publishes a plain list, and water heaters are on the permit side of it.

The city’s “When is a Permit Required?” handout, linked from the Residential Additions and Alterations page, opens with the exemption: “Projects that are cosmetic, such as painting, wallpapering, carpeting, cabinets and trim work, etc., do not require permits. Additionally, permits are not required when replacing fixtures on existing wiring or plumbing.”

Five lines on the list of work that does need a permit touch plumbing:

• “Plumbing work.”
• “Water heaters (replacing or adding).”
• “Water softeners.”
• “Replacing water or sewer lines. (Repair work such as exchange of washers and faucets is exempt.)”
• “Irrigation systems (lawn sprinklers).”

The handout says of itself that this “is not an all-inclusive list”, and its revision marking reads 09/28/16. It is a 2016 document, and the city adopted a new code cycle on 1 August 2025.

Now the statute, because this is where guidance about Texas cities goes wrong. Tex. Occ. Code section 1301.551(c) requires a city that adopts a plumbing ordinance to 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.” That stops the state compelling a permit for those five jobs. It does not stop a city requiring one.

Plano’s list overlaps the statutory five without matching them. Faucet and washer swaps are exempt in Plano’s words too. Ballcocks, water control valves, garbage disposals and water closets appear nowhere in what Plano publishes, in either direction. On those four the city’s position is silence, not permission.

Water heaters are the question everybody asks, and Plano’s answer carries no qualification. The statewide picture is in do you need a permit to replace a water heater in Texas? Plano adds one detail worth knowing before you accept a tankless quote: its water heater handout says “A gas load calculation shall be provided on the jobsite when calling the first inspection.”

What happens when it is skipped: skipping a plumbing permit in Texas.

Registration: required of the plumber, and free

A plumbing contractor must register with Plano, and Plano charges nothing for it.

The city’s Contractor Registration Requirements handout groups plumbers with the fire and access control trades and sets the terms: a current Texas State Plumbing License, a current driver’s license, the state license carried on the job, and renewal every year. On money it is one line: “No registration fee will be assessed.”

The current fee schedule agrees by omission. Ordinance No. 2025-11-4, which the city labels “Fee Schedule” and dates “effective January 2, 2026”, lists annual registration fees for General Contractor, Irrigation Contractor, Sign Contractor and Solid Waste Disposal Contractor. Plumbing is not among them.

That is the statute working. Section 1301.551(g) says a responsible master plumber or plumbing contractor required to obtain a permit “is not required to pay a plumbing registration fee or administrative fee in a municipality or any other political subdivision.” A plumber who puts a Plano registration fee on your invoice is charging for something the city says it does not charge.

Fees: a current schedule, and one line that points nowhere

Plano publishes a current, dated fee schedule. Then it spoils the effect. The schedule’s own entry reads “PLUMBING PERMIT (See Mechanical Permit Fee)”, and it contains no Mechanical Permit heading to turn to.

The nearest thing to a residential trade figure is a heading, “SIMPLE TRADE PERMITS (MEP) each”, with a row under it reading “Residential” and “85.00”, and the Miscellaneous Simple Permit Application carries a Plumbing / Residential checkbox. We are not going to tell you those are the same line, because the city does not say so.

What the schedule does state plainly:

• Re-inspections: first $75.00, second $100.00, third $125.00, each additional $150.00.
• Same day inspection, per trade: $150.00.
• After hours inspections and Saturdays: $200.00.
• Plumbing site pre-build: $360.00.

One warning about the city’s own links. The Building Inspections landing page links the current schedule. The Residential Permits page still links a file titled “Building Inspections Fee Schedule” that is Ordinance No. 2020-3-6, repealed in its entirety by the 2025 one. Check the ordinance number on whatever you open.

Inspections

Plano gives contractors three automated ways to schedule, and routes homeowners to a person instead.

They schedule through eTRAKiT, through the SelecTXT text service, or through the automated line on 972-424-2534, entering a code per trade: 620 is a final plumbing, 650 a final plumbing service certificate, 680 a water heater final.

Homeowners are handled by hand. The city’s Inspection Services page says: “For Homeowner acquired permits (scheduling inspections), please call 972-941-7140 between 8 am and 5 pm or email your request. Please allow 24 hours for emailed requests to be scheduled.”

Same day inspections must be requested by 11am, Saturday inspections by 3pm on the Friday before.

One Plano requirement will catch an under-slab repipe. The city’s inspection requirements sheet for residential water and sewer line replacement under a slab, new in January 2025, asks the plumber for photos of all work, a schematic of how the piping was constructed, and “A letter from the Responsible Master Plumber (RMP), clearly describing the work that was completed. The letter must be signed and dated by the RMP and list the master’s license number.”

What we could not verify

Three things, stated so nobody mistakes silence for an answer. Plano publishes no plumbing permit fee we can point to with confidence. Beyond the registration exception and the handout’s line about listing yourself as the general contractor, it publishes no condition on a homeowner permit, and nothing about whether that homeowner may perform the plumbing themselves. And its exempt list is a 2016 handout the city did not refresh at the 2024 code adoption.

All three are one call to 972-941-7140. If the city tells you different, we want to know.
