Can You Get a Plumber License with a Criminal Record? (2026)

If you have a criminal record and want to become a licensed plumber, you may be wondering how your past will affect your ability to get licensed. Like other trade professions, plumber licensing focuses primarily on technical competency, though background checks are increasingly common. A criminal record does not automatically disqualify you — licensing boards evaluate each applicant based on individual circumstances.

This guide explains what plumber licensing boards generally consider, provides a state-by-state overview of background check requirements based on our data, and outlines steps you can take to strengthen your application.

How Plumber Licensing Boards Evaluate Criminal Records

Plumber licensing boards primarily focus on technical competency and safety knowledge. When a background check is required, boards typically consider the following factors:

• Nature and severity of the offense — Boards distinguish between misdemeanors and felonies, and between violent and non-violent offenses.
• Relationship to the profession — Because plumbers often work in homes and businesses, offenses involving theft, burglary, or fraud may receive closer scrutiny. However, the primary licensing focus remains on technical ability and code compliance.
• Time elapsed since the offense — A significant period of time since the offense, combined with a clean record, is generally viewed favorably.
• Evidence of rehabilitation — Completing apprenticeship programs, maintaining steady employment, and obtaining character references can demonstrate rehabilitation and professional competence.
• Number of offenses — A single, isolated incident is typically viewed differently than a pattern of criminal behavior.

Steps to Improve Your Chances

If you have a criminal record and want to pursue a plumber license, these steps may help strengthen your application:

1. Obtain your criminal record — Request a copy of your record so you know exactly what the licensing board will see. Errors on background checks are more common than you might expect, and correcting them before you apply can prevent delays.
2. Check your state board’s policy — Many state plumbing boards publish guidelines on how they evaluate criminal records. Look for any disqualifying offenses, waiting periods, and fair chance policies.
3. Consider a pre-application review — Some states offer a preliminary review process that lets you find out whether your record might affect your eligibility before you invest in an apprenticeship.
4. Gather rehabilitation evidence — Collect documentation of completed treatment programs, community service, steady employment, apprenticeship completion, and character references.
5. Consult an attorney — A lawyer experienced in occupational licensing can review your specific situation and advise on the best approach for your application.
