McKinney, Texas
McKinney Checks the Licence, Not the List, When You Hire a Plumber McKinney Wide
We built three city pages this week in three different states and asked each one the same question: who has to be on a list before they may work on your pipes? The answers were so different that the comparison is worth putting at the top of this page.
McKinney is the loosest of the three, and deliberately so. Its building inspections department registers electrical contractors and master electricians, mechanical licence holders and plumbing licence holders, and it charges no registration fee for any of them. For general contractors it goes further: there is no fee and no form to fill out, and a portal account is the whole of it.
What the city asks for instead is a name and a signature. A Signature Verification Form has to be submitted for each project, signed by all master licence holders, before a permit is issued. McKinney is not maintaining a gate. It is checking that a state licensed master has personally put their name to your job.
The Registration Question
Read Both Statements, Because the City Makes Two
We are going to report this the way the city says it rather than smoothing it into one sentence, because the two statements apply to different people and collapsing them would mislead somebody.
For the licensed trades, the position is that licensed contractors must register with the City of McKinney before a permit can be issued, and the department lists the contractor types it registers as electrical contractors and master electricians, mechanical licence holders and plumbing licence holders. No registration fee is charged for any of those types.
For general contractors, the position is that there is no fee and no form to fill out and that contractor registration is not required, with a portal account being all that is needed. Contractors set up an account and email copies of the required licences so that the account can be reviewed and approved.
And the control that applies to everybody is the signature. A Signature Verification Form must be submitted for each project and signed by all master licence holders before a permit will be issued. That is a per project requirement rather than a once a year one, and it puts a named individual holding a state master licence behind each permit. If you are hiring, that is a fair thing to ask about: whose master licence is going on the form.
This is a genuinely different regulatory philosophy from its neighbours, and it is worth understanding rather than judging. Some cities build a local list and control who gets on it. McKinney leans on the state licence, removes the friction and the fee, and puts the accountability on a signature attached to a specific job.
Compare that with Rowlett, built the same day as this page, which states that plumbing contractors must be registered with the city in order to obtain a permit, publishes the list of currently registered contractors, and additionally requires an internal camera video of the sewer line before any final inspection. And compare both with Littleton in Colorado, where a water and sanitation district serving about 6,900 connections issues its own licence backed by a $10,000 surety bond. Three levels of government, three answers.
Where It Comes From, Where It Goes
The Same District Sells the Water and Takes It Back
Ask who owns the pipe, who takes the waste and who issues the permit, and McKinney gives the tidiest answer in this batch. The city purchases its water from the North Texas Municipal Water District, which uses Lavon Lake as its primary raw water source with additional raw water from Lake Texoma, Lake Chapman and reuse, and which supplies water to approximately 1.7 million people across ten counties.
On the waste side the answer is the same body. The city conveys all the wastewater from homes and businesses through wastewater pipes to the district, where it is treated. The city owns the collection network and the permit counter. The district owns both ends of the water.
Then the loop closes in a way that is genuinely unusual to state out loud. The city explains that the treated wastewater, known as effluent, is released into local waterways where it is used again to supply drinking water, to irrigate golf courses and to sustain aquatic life. Water leaving a McKinney house is part of the regional supply again downstream.
That is worth setting against Rowlett, which buys treated water from the same district and then contracts with the City of Garland to treat all of its wastewater. Same supplier, opposite answers on the waste side. One suburb hands its sewage to the city next door under a contract between two municipalities; the other hands it back to the district that sold it the water in the first place.
Before You Book Anything
The Move Test
McKinney draws its household permit line in a place that is easy to remember once you have seen it, and it is not where most people assume. The question is not what the fixture is. The question is whether any pipe comes out or changes position.
- Is any piping being removed, replaced or relocated? The city states that repairing minor leaks does not need a permit as long as the removal, replacement or relocation of piping is not required. That clause is the whole test. If pipe moves, you are in permit territory.
- Is the fixture going back in exactly the same place? Replacing toilets, faucets and other fixtures in the same location does not need a permit. Moving one does, because moving a fixture means moving pipe.
- Is it just a blockage? Unclogging drains and sewers does not require a permit. That is a broader exemption than several cities allow, and it is stated plainly rather than implied.
- Is it a water heater? Then yes, and the city routes it explicitly, telling applicants to search Water Heater in the portal application assistant. A water heater is permit work here regardless of how straightforward the swap looks.
- Is it gas, or a meter inspection, or stand-alone plumbing? The city routes those through a residential stand-alone plumbing application. Gas work is not a category to improvise in.
- Is it an appliance rather than a fixture? Replacing non-permanent components such as kitchen appliances does not need a permit. The distinction the city is drawing is between what is connected to the system and what is part of it.
- Who is signing? Whatever the answer above, if a permit is involved a Signature Verification Form signed by the master licence holder has to be in before it issues. Ask who that is.
The reason this framing is better than a list is that it survives contact with a job nobody wrote a rule about. A tap that drips is a fixture question. A tap that drips because the stub-out behind it has corroded is a piping question, and the answer changes even though the visible symptom did not. Asking whether pipe moves gets you to the right answer without needing to find your exact situation on a webpage.
One honest caveat. We did not read a McKinney fee schedule, turnaround time, adopted code edition or local amendment when this page was written, so none is quoted here. The exemptions above are what the city publishes for home repairs, and if your job sits near the line, the building inspections department is the place to settle it rather than a web page.
Ground and Houses
A Young City on Old Ground
McKinney has a genuine nineteenth century downtown and then, a short distance away, a city that mostly did not exist thirty years ago. That combination produces two entirely different sets of plumbing problems within a few miles of each other, and it is the main thing to establish before diagnosing anything.
Around the historic square and the older east side, the issues are the ones any old Texas town has: cast iron and clay drainage with joints, galvanised supply that has corroded from the inside, and a century of alterations layered on top of each other. In the growth neighbourhoods the housing is slab on grade with copper or PEX supply and PVC drainage, and the problems are younger: fittings, settlement and workmanship rather than material failure.
What unites them is the ground. North Texas expansive clay swells when it takes water and shrinks when it dries, and the movement is seasonal rather than gradual. A slab that moves takes the pipes under it with it. That is why a leak appearing after a wet spring following a dry summer is a pattern rather than bad luck, and why foundation and plumbing problems here are so often the same conversation.
For newer houses there is a specific and under appreciated version of this. A ten year old slab on expansive clay has been through ten cycles of that movement, and the failure point is usually a fitting or a joint rather than a length of pipe. That is why a camera survey on a modern house is not a waste of money, and why a leak in a young home does not mean somebody built it badly.
We do not have a hardness figure for McKinney and we are not going to invent one. The water arrives treated from a regional district, and the current water quality report is the right source for a number if you need one for sizing a softener or setting a descaling interval. Our Texas page covers the state wide picture.
Where Requests Come From
McKinney Neighbourhoods and the Collin County Edges
The list below is where enquiries reach us most often, and it is not a claim about coverage.
McKinney is the Collin County seat and it is surrounded by cities that have grown into it. Frisco, Allen, Prosper, Melissa, Princeton and Fairview all share edges with it, and each one adopts and amends its own codes on its own schedule. A neighbourhood name is not a jurisdiction, and the permit desk changes at the city line even where the water does not.
The city has also annexed outward over decades, so an address on the fringe may be city, may be another city, or may be unincorporated county. That matters for permits and for who inspects, and it is a five minute check that saves a wasted phone call to the wrong building department.
For anything involving a dig, call 811 first, regardless of which line you are on. In a city that has been building continuously for thirty years the density of buried services in newer neighbourhoods is higher than people expect.
What We Handle Here
Plumbing Services Across McKinney and Collin County
Slab leaks lead here because the combination that causes them is everywhere: slab on grade construction over expansive clay, with copper supply under the concrete in the 1990s and 2000s neighbourhoods. The cost of the repair is decided almost entirely by how precisely the leak is located first, which is what leak detection is for.
Drain problems on this soil are often a movement symptom rather than a blockage. Drain cleaning handles the clearable end, and a camera survey establishes whether you have roots at a joint, a settled section holding water, or a genuine break. Guessing between those is expensive when the answer involves opening a slab or a driveway.
Where a line is greased or scaled rather than obstructed, hydro jetting scours the pipe wall instead of punching a hole through the middle of the problem. Sewer line repair covers the structural end for the older neighbourhoods around the square.
Water heaters are permit work in McKinney, which makes the choice of who does it more consequential than in a city that exempts a like for like swap. Water heater repair covers tank and tankless work, and gas line services covers the fuel side, which is the part of a water heater job least worth improvising on.
In the older east side, galvanised supply corrodes from the inside and shows as falling pressure rather than a leak, so repiping is often the honest answer rather than another patch. Commercial plumbing covers the US 380, Custer Road and Eldorado corridors. Emergency plumbing covers what to do first when water is moving and you cannot stop it. We publish no response time for McKinney, because a number typed into a web page helps nobody standing in water.
McKinney Plumbing Questions, Answered Straight
What McKinney households actually ask about contractor registration, which repairs need a permit, where the water comes from and why young houses get slab leaks.
The city makes two statements and they apply to different people, so we will give you both. For the licensed trades it states that licensed contractors must register with the city before a permit can be issued, and that it registers electrical contractors and master electricians, mechanical licence holders and plumbing licence holders, with no registration fee for any type. For general contractors it states that there is no fee and no form to fill out and that registration is not required, with a portal account being all that is needed. Ask the building inspections department which applies to your job.
It is the control McKinney uses instead of a fee and a local list. The form must be submitted for each project and signed by all master licence holders before a permit is issued. It puts a named individual holding a state master licence personally behind your specific job, rather than relying on an annual registration that was completed months ago. If you are hiring, whose master licence goes on that form is a fair question to ask.
Usually not, and the wording matters. The city states that repairing minor leaks does not need a permit as long as the removal, replacement or relocation of piping is not required, and that replacing toilets, faucets and other fixtures in the same location is also exempt. So a tap swap is fine and moving a tap is not, because moving a fixture means moving pipe. The test to apply is whether any pipe comes out or changes position.
No. The city lists unclogging drains and sewers among the repairs that do not require a permit. That is a broader exemption than several cities allow and it is stated plainly. What changes the answer is if clearing the blockage turns into replacing or relocating pipe, at which point you are back in permit territory.
Yes. The city directs applicants to search Water Heater in the portal application assistant to get started, and routes gas and meter inspection work through a residential stand-alone plumbing application. That is a stricter position than some Texas cities take on a like for like swap, so it is not a job to treat as a weekend project.
The city purchases its water from the North Texas Municipal Water District, which uses Lavon Lake as the primary raw water source with additional raw water supplied by Lake Texoma, Lake Chapman and reuse. The city states that the district supplies water to approximately 1.7 million people across ten counties.
The same district that supplies the water. The city states that it conveys all the wastewater from homes and businesses through wastewater pipes to the North Texas Municipal Water District where it is treated, and that the treated effluent is then released into local waterways where it is used again to supply drinking water, irrigate golf courses and sustain aquatic life. That is a different arrangement from Rowlett, which buys from the same district but contracts with the City of Garland to treat its wastewater.
Because the ground is much older than the house. North Texas expansive clay swells when wet and shrinks when dry, and that movement is seasonal, so a fifteen year old slab has been through fifteen cycles of it. The failure usually shows up at a fitting or a joint rather than along a length of pipe, which is why a leak in a modern home is not evidence that it was built badly and why a camera survey is worth doing rather than assuming.
