Texas is moving its adopted plumbing codes to the 2021 editions. Here is where that actually stands.
If you have heard a rumor that the code is changing, it is not a rumor. It is a proposed rule, it is public, and it is not adopted yet. Here is the honest status.
What is being proposed
The Texas State Board of Plumbing Examiners has proposed an amendment to 22 TAC 367.2, the rule that names which editions of the plumbing codes are enforceable in Texas. The move is from the 2018 editions to the 2021 editions.
Rule 367.2 is short and it matters more than its length suggests. It is the rule that decides which book you are actually being inspected against.
Where it stands today
- Published for comment: August 14, 2026
- Comment deadline: 30 days from publication, so September 13, 2026
- Status right now: proposed, not adopted
That last line is the one to hold onto. A proposed rule is not the law. Until the board votes to adopt and the adopted version is published by the Secretary of State, the currently adopted editions still govern your work. Anybody telling you to install to the 2021 book today because they read about the proposal is getting ahead of the state.
What a code edition change actually costs you
Three editions of the same code are never three different trades. Most of what you do on Monday will be identical. But a code cycle moves a handful of specific things, and those are the ones that cost money when you get them wrong:
- Sizing tables. The math does not change. The table you look the number up in sometimes does.
- Materials and joining. What is listed, what is approved for what service, and what an inspector will accept without a fight.
- Venting. Where the allowances moved, and which arrangement you have been running for ten years that is now spelled differently.
- Fixture and flow provisions. These interact with the Texas water conservation statutes, which are separate from the code and which do not move on the code cycle.
The trap is the last one. Texas has its own statutory requirements on flow rates and on lead content, and those are not the code. A code edition change does not touch them. Plenty of plumbers assume a new code book resets everything, and it does not.
What you should do about it right now
Nothing, other than know it is coming. Do not rebuy books, do not change your standard details, and do not let a supply house tell you a product is now acceptable because of a rule that has not been adopted. When it is adopted, the change is a half hour of reading, not a new career.
How to check it yourself
Do not take our word for it, and do not take anybody else's. The board posts proposed amendments publicly, and the Secretary of State keeps the official text of the adopted rules. Both are linked below. If you read a claim about Texas plumbing rules anywhere, including here, the fastest way to settle it is to open the rule.
