Plumbing License South Dakota: No Journeyman or Master, and Two License Calendars Six Months Apart (2026)

The South Dakota Plumbing Commission is the state board that licenses every plumber in the state, and if you have been searching for a journeyman or master plumber license from that commission, here is the first thing to know: it does not issue either one. Neither title exists in the statute, the administrative rules, or on any application the Commission publishes.

That is not a technicality. It is the reason so many guides to South Dakota plumbing licensing are wrong from the first paragraph. Pages that lead with "journeyman" and "master" are describing Minnesota, or Iowa, or a generic national template, not South Dakota's own vocabulary.

At a glance

• No journeyman or master plumber license exists at the state level; the ladder runs apprentice, third-year apprentice, plumber, plumbing contractor (SDCL 36-25-1).
• Plumbing contractor and plumber licenses expire December 31 and must be renewed by the following January 31; five specialty trades and the on-site wastewater license expire June 30 and must be renewed by the following July 31 (SDCL 36-25-19.4).
• Current contractor fees: $50 application, $100 exam, $275 initial license and annual renewal (ARSD 20:53:12, effective July 2, 2025).
• Four hours of continuing education are due every year, two of them on code (SDCL 36-25-32).
• A rural or small-town restricted license waives part of the exam and ladder for towns under 1,500 people (SDCL 36-25-17.1).

South Dakota runs a four-rung plumbing ladder with its own vocabulary, six separate specialty trades that sit beside it, a restricted license for small towns, and two renewal calendars six months apart. This guide walks the real system, built from the South Dakota Plumbing Commission's own current pages and forms, South Dakota Codified Law chapter 36-25, and the Administrative Rules of South Dakota article 20:53. For every other state, see how to get a contractor license in each state.

The four rungs South Dakota actually issues

The ladder has four steps, and the names matter because they are what appears on the application form itself, not a journeyman or master title borrowed from somewhere else.

Notes on the table:

• All experience and hour figures come from the Commission's own licensing page and match ARSD 20:53's experience rules.
• "1,900 per year" is a per-year floor, not an average; see the next section.

Apprentice plumber

You apply, pay the $20 application fee, and once approved the Commission tells you what license fee is due for that year of apprenticeship. The license issues after that fee is paid.

Third-year apprentice plumber

This rung surprises people, and it is genuinely useful. To apply you need two years as an apprentice plumber with at least 1,900 hours in each of those two years. What it buys you is real: after 3,800 hours across those two years, and after passing a state-administered exam, you may work without supervision during your third and fourth year, but only on single-family dwellings. That lets a third-year apprentice run residential work alone, which changes the staffing math for a residential plumbing company in this state.

Plumber

Four years as an apprentice plumber, at least 1,900 hours per year across those four years. A military provision applies here: credit for military plumbing work is given at the rate of one year of credit for every two years served, up to a maximum of five years.

Plumbing contractor

Six years as a plumbing contractor, plumber, or plumber's apprentice, with at least two of those six years at plumber or contractor level, and at least 1,900 hours per year across all six. Read that middle clause carefully: six years of apprentice time alone does not qualify you. Two of the six have to be at plumber level or above.

Moving up the ladder, in order:

1. Register as an apprentice plumber and log verified hours under a licensed plumbing contractor.
2. After two years and 3,800 verified hours, sit the third-year apprentice exam to work unsupervised on single-family homes.
3. After four years and 7,600 verified hours, apply for the plumber license and sit its exam.
4. After two more years at plumber or contractor level, six total, apply for the plumbing contractor license and sit its exam.

The hours are a floor, not a bank

Third-party guides often convert these requirements into a single total, "7,600 hours" for the plumber license or "11,400" for the contractor license. The arithmetic is not wrong, but the framing is. South Dakota does not ask you to accumulate a bucket of hours; it asks for a set number of years, each of which contains at least 1,900 hours. A year logged at 1,400 hours is not a qualifying year, and stacking two light years never produces one good one.

This matters because verification happens per employer and per period. A licensed plumbing contractor or specialty contractor you worked under must sign off on your experience, or the out-of-state equivalent must. You cannot verify your own experience.

The six specialty ladders beside plumbing

The Plumbing Commission does not only license plumbers. It licenses five other trades, each with its own contractor and installer tier, plus a standalone wastewater license with no published experience ladder at all.

• Sewer and water, contractor needs one year as a sewer and water installer; installer needs two years as a sewer and water apprentice.
• Appliance, contractor needs one year as an appliance installer; installer needs two years as an appliance apprentice.
• Manufactured and mobile home, contractor needs one year as an installer; installer needs two years as a mobile home apprentice.
• Underground irrigation, contractor needs one year as an installer; installer needs two years as an apprentice.
• Water conditioning, contractor needs one year as an installer; installer needs two years as an apprentice.
• Individual and small on-site wastewater system installer, the septic license. There is no published experience ladder; you complete the certification application and submit it with the application fee.

The pattern holds across all six: one year from installer to contractor, two years from apprentice to installer, a far shorter runway than the plumbing ladder. That is why many South Dakota companies hold a specialty contractor license alongside, or instead of, a plumbing contractor license. Under SDCL 36-25-17.3, an individual and small on-site wastewater system may only be altered, repaired, constructed, or installed by someone holding that specific installer license.

The restricted license nobody writes about

SDCL 36-25-17.1 lets the Commission waive part of the licensing requirements for an applicant in a rural area or a municipality of fewer than 1,500 people, by the last federal decennial census, if the applicant passes an exam on the laws and rules governing plumbing. The trade-off sits in the same section: anyone licensed this way is restricted to performing plumbing in a rural area or a town under that same population line.

That is where the restricted plumbing contractor and restricted plumber license types come from. They show up in the Commission's continuing education rules and in statute, but not on the main licensing page, which is why they tend to vanish from third-party summaries. If you work small-town South Dakota, this is a legitimate and faster route into licensed work. If you plan to bid in Sioux Falls or Rapid City, it is not, and you need the unrestricted license.

Who runs this, and why the fees keep moving

The Commission has five members appointed by the Governor: a plumbing contractor, a plumber, a representative of the state Department of Health, and two consumer members. It meets quarterly, three virtual sessions and one in-person meeting each July, and it is self-supporting, funded entirely by the fees applicants and licensees pay. That self-funding structure is worth knowing before you read the fee schedule below; it is also why a July 2025 rule change raised several of these fees specifically to keep the Commission funded long term.

What it costs

South Dakota rewrote its fee rules in 2025. The current schedule sits in ARSD 20:53:12, effective July 2, 2025, which means most fee figures published before that date are stale.

Government and board fees are set by the Commission and change. Verify current amounts with the Commission before you send money.

Initial application fees (non-refundable, due with the application):

• Apprentice license, $20
• Installer and plumber license, $50
• Contractor license, $50

Examination and reexamination fees (non-refundable, due before the exam):

• Plumber license, $100
• Installer license, $100
• Contractor license, $100
• Third-year apprentice plumber licensed by examination, $50

Initial license fee and annual license renewal fee:

• Apprentice license, $20 the first year, $30 the second year, $40 the third year, $50 for four or more years
• Plumber or installer license, $105
• Appliance, manufactured and mobile home, underground irrigation, or water conditioning contractor, $200
• Sewer and water contractor, $235
• Plumbing contractor, $275

Other fees:

• Temporary license, $50
• License verification, $20 per request
• License duplicate or replacement, $10

Three details are easy to miss and expensive to learn late. A license is not transferable. All fees are non-refundable. And license and renewal fees must reach the Commission before the license issues; paying late does not just delay paperwork, it delays the license itself.

The two-calendar trap, and the city layer that makes a third

This is the single most useful thing on this page for anyone running a South Dakota plumbing company, and it is easy to get wrong even when you have read the statute. The two groups share the same shape of renewal window, a one-month grace period after expiration before a reinstatement application is required, but their expiration dates sit six months apart.

Under SDCL 36-25-19.4, licenses expire annually on two different dates:

• Plumbing contractor and plumber licenses expire December 31.
• The five specialty contractor and installer licenses, plus the on-site wastewater system installer license, expire June 30.

What several third-party guides, and an earlier version of this page, get wrong is treating a single long grace period as covering both groups. The Commission's own current renewal forms draw the line in the same place for each group: a plumbing contractor or plumber license expires December 31 and may be renewed no later than the following January 31, and a specialty contractor, installer, or wastewater installer license expires June 30 and may be renewed no later than the following July 31. Miss that one-month window in either group and the Commission requires its reinstatement application instead of its renewal form.

Miss either deadline and you are not simply late; you need the Commission's reinstatement application rather than its renewal form, for either group. File within one year of the original expiration and the exam is waived. File after that year and you are back to an initial application, with the $50 application fee and $100 exam fee due again.

A company holding both a plumbing contractor license and a specialty license, say underground irrigation, is tracking two expiration dates six months apart, each with its own one-month renewal window. The Commission mailed 2026 to 2027 specialty renewal forms in April 2026, on the June cycle, while the plumbing side was still eight months from its own December 31 deadline.

Companies working inside Sioux Falls carry a third calendar on top of these two. The city requires its own Journeyman Plumber and Master Plumber licenses, issued only after the state license, and renewed every two years rather than annually; an expired city license cannot be renewed at all more than 12 months after expiration, and requires retesting instead. Sioux Falls is the one place in South Dakota where "journeyman" and "master" are real license titles, just not state ones.

The exam, and the scheduling problem in it

South Dakota does not send applicants to a national testing vendor. The Plumbing Commission itself administers and sets the educational, training, and exam requirements for every occupation it licenses.

Where you sit the exam is worth planning around:

• Pierre: exams run at any time by advance appointment; call or email the Commission to schedule.
• Sioux Falls and Rapid City: exams run only when the office has enough applicants to justify the trip, and the Commission sets eight to 10 applicants as the minimum to warrant travel.

That is a real constraint. If you are waiting on a Sioux Falls session, your test date depends on seven to nine other people applying at the same time. As of this writing, the Commission has sessions posted for Rapid City on October 23, 2026 and Sioux Falls on October 30, 2026; confirm both are still on before you plan travel around them.

For first-time examinees, the application fee and exam fee must both be paid, and the applicant approved, before any exam can be scheduled, in Pierre or elsewhere. For re-exams, the re-exam fee must be submitted at least two weeks before a scheduled Rapid City or Sioux Falls session to be added to it.

Continuing education: four hours, and two of them are code

Several widely shared pages state that South Dakota requires 16 hours of continuing education every two years, with 8 hours on code. That figure is off by a factor of four.

The Commission's rule is four hours annually. Under SDCL 36-25-32, to renew each year, every licensee holding a plumbing contractor, restricted plumbing contractor, plumber, restricted plumber, or third-year apprentice plumber license must complete at least four hours of continuing education on the plumbing trade during the previous calendar year, and two of those four hours must cover code.

Proof of completion must reach the Commission before renewal. If your provider does not report directly to the Commission, you supply the certificate yourself. The Commission may grant exceptions for health, military service, or other reasonable cause, with adequate proof.

Who needs a license, and the four exceptions

SDCL 36-25-17 is the operative rule: no one may engage in licensed plumbing work on any property connected to a public waterworks or sewerage system without a Commission license. Four exceptions apply, for work that still meets the Commission's minimum standards:

• Plumbing on premises the person owns and actually occupies as their residence.
• Plumbing on a single-family dwelling under construction, if the person owns it and intends to occupy it when construction finishes.
• Repair work on premises where the person is employed, performed by that employee.
• Repair work on the person's own property.

The third exception is the in-house maintenance carve-out, and it is narrower than people assume. It covers repair, on premises where you work. It does not cover installation, and it does not cover sending maintenance staff to a second property.

Local governments keep their own authority on top of the state floor. SDCL 36-25-16 lets a municipality adopt and enforce its own plumbing requirements and fees, which is exactly how Sioux Falls ended up with its own Journeyman Plumber and Master Plumber licensing layer described above, on top of the state's apprentice, plumber, and contractor system.

The part that decides who can hold the license

South Dakota's statutory definitions in SDCL 36-25-1 describe the ladder in terms of employment, not just skill. A plumber is "any person other than a plumbing contractor who, as that person's principal occupation, is engaged as an employee of, or otherwise working under, the direction of a plumbing contractor in the installation of plumbing, and who is lawfully qualified and registered as a plumber." A plumber's apprentice is "any person other than a plumber or plumbing contractor who is engaged in working as an employee of a plumbing contractor under the immediate and personal supervision of either a plumbing contractor or plumber."

There is no separate company license in this state. The plumbing contractor license is both the individual credential and the authority to conduct the business of plumbing. Everyone below that license is defined by their employment relationship to the person who holds it, and the license itself is not transferable, so it cannot move between companies.

This is the same structure other states express through a named qualifying agent or responsible managing employee; South Dakota just writes it into the employment definitions instead of giving it a title. A qualifying agent QUALIFIES the company as an owner or full-time W-2 employee who actually supervises the work, a structure explained in full in what a qualifying agent is and in hiring a qualifying agent. For a company that does not already have a licensed plumbing contractor on staff, our contractor qualifier services are built around placing that person the right way, the same point South Dakota's non-transferability rule reinforces.

Penalties

SDCL 36-25-30 makes any violation of the plumbing chapter a Class 2 misdemeanor for "any person, firm, or corporation." Under SDCL 22-6-2, a Class 2 misdemeanor carries a maximum of 30 days in county jail, a $500 fine, or both.

The Commission separately holds authority to refuse, revoke, or suspend a license under SDCL 36-25-27. SDCL 36-25-23 allows temporary, revocable permits for a period not to exceed one year, for a $50 fee. A Commission rule used to narrow that to three months, but that rule, ARSD 20:53:02:19, was repealed effective July 2, 2025, the same reform that rewrote the fee schedule, so the one-year statutory ceiling is the operative rule today.

Rules that just changed, and the ones still moving

The fee overhaul above, effective July 2, 2025, is not the only rulemaking in motion. The Commission held a public hearing by Microsoft Teams on October 2, 2026, on proposed amendments to administrative provisions covering notifications and licensing procedure (ARSD 20:53:02:08, 02:09, 02:10, 02:20, 02:22, 02:24), plumbing permits (20:53:10:02, 10:04), a new chapter 20:53:13, and a state plumbing code provision (20:54:02:01). The stated aim is to align notification requirements with a new licensing database, align the rules with SDCL 36-25, and clean up outdated language.

Written comments closed September 29, 2026, and the state's Interim Rules Committee held its own hearing on October 14, 2026. As of this writing, no adopted version or effective date has been published. If you hold a South Dakota plumbing license, check the Commission's rulemaking page for the outcome before assuming today's notification deadlines still match what was proposed.

Frequently asked questions

Does South Dakota have a journeyman plumber license? Not at the state level. The Commission licenses apprentice plumbers, third-year apprentice plumbers, plumbers, and plumbing contractors; "plumber" is the closest state equivalent to a journeyman. Sioux Falls does issue its own city Journeyman Plumber license, on top of the state one, but that is a municipal credential, not a state one.

Does South Dakota have a master plumber license? Not at the state level. The top state rung is the plumbing contractor license, requiring six years of experience with at least two at plumber level or above. Sioux Falls again is the exception, with its own city Master Plumber license required for anyone paid for plumbing work inside city limits.

How long does it take to get a plumbing contractor license in South Dakota? Six qualifying years at minimum, each containing at least 1,900 hours, with at least two of those years at plumber or contractor level. Realistically that means four years to the plumber license, then two more before sitting the contractor exam.

Can an apprentice work alone in South Dakota? Yes, in a narrow case. After two years and 3,800 hours, and after passing a state exam, a third-year apprentice plumber may work without supervision in their third and fourth years, but only on single-family dwellings.

When does my South Dakota plumbing license expire, and when must I renew it? Plumbing contractor and plumber licenses expire December 31 and must be renewed by the following January 31. The five specialty licenses and the wastewater installer license expire June 30 and must be renewed by the following July 31. If you hold licenses in both groups, you are tracking two different deadlines six months apart.

What happens if I miss the renewal? For a plumbing contractor or plumber license, you have until January 31 to renew; for a specialty or wastewater installer license, you have until July 31. After that, a reinstatement application is required for either group, with the exam waived only if you file within one year of the original expiration.

How much does it cost to get licensed as a plumbing contractor in South Dakota? On the state side, $50 application, $100 exam, and $275 for the license and each annual renewal, plus continuing education. What it costs to get a company licensed and operating depends on the trades you hold, the cities you work in, and whether you already employ someone who can hold the contractor license.

Do I need a South Dakota HVAC license too? There is no state HVAC license in South Dakota, but Sioux Falls and Rapid City license mechanical work locally. The South Dakota HVAC licensing guide covers both cities.

Do I need a city license if I already hold the state plumbing license? In Sioux Falls, yes. The city requires its own Journeyman Plumber or Master Plumber license, applied for only after the state license, and renewed every two years on a schedule separate from the state's annual cycle.

Where this leaves you

South Dakota is a state where the vocabulary is the real barrier. The ladder is not unusually long, the fees are moderate, and the Commission is accessible by phone. But if you go in looking for a journeyman license and a master license from the state, you will spend weeks looking for two things that do not exist there, and you may miss the third-year apprentice rung and the rural restricted license, the two fastest legitimate routes into licensed work in this state.

The other thing to plan for is the top of the ladder. The plumbing contractor license is the business credential, it is not transferable, and everyone below it is defined by their employment relationship to the person holding it. Companies that grow faster than their licensed contractor can grow into the role are the ones that end up stuck.

If your company needs a licensed plumbing contractor to hold that credential and you do not have one on staff, that is the problem we solve. We place qualifying agents as full-time W-2 employees, never as contractors and never on a per-project basis, because that is the only structure that survives contact with definitions like South Dakota's. If South Dakota is one of several states you are working toward, our licensing services in all 50 states cover the rest, or browse licensing requirements by state directly. For the electrical side of South Dakota, which runs through a separate commission entirely, see our South Dakota electrician licensing guide, and for a neighboring state that structures its plumbing ladder very differently, compare North Dakota plumbing licensing.
