Home Addition — South Dakota license requirements
01 The project
The starting point is the work itself — Home Addition in South Dakota. The job determines which trades are involved, and the trades determine which license classifications may be required.
No project components are seeded for this project — we do not invent component lists without evidence.
02 Jurisdiction
This project is evaluated for South Dakota — the no-general-contractor-licence state. The State Electrical Commission (SDCL ch. 36-16) licenses only electrical, and only on its own terms: no dollar threshold, a $10,000 undertaking with liability insurance, biennial June 30 even-year renewal; the State Plumbing Commission (SDCL ch. 36-25) runs the plumbing ladders on annual December 31 licences; and every person entering a construction contract needs DOR's 2% contractor's excise licence. Local permits and any municipal registration are a separate layer under SDCL 36-16-35. South Dakota jurisdiction page.
sdlegislature.gov serves a JavaScript app shell to this project's fetcher, so SDCL ch. 36-16 and ARSD 20:44 were read IN FULL from DLR's official Wiring Bulletin PDF and ARSD 20:53 from the Commission's LRC-approved rule package PDF; the ch. 36-25 penalty cross-reference (§ 36-25-30) is surfaced from the official rule page and flagged reported. Permit fees, local construction rules and any municipal business-licence rate were not researched and remain LOCAL_AUTHORITY_REQUIRED. Both conflicts ($15/$20 wiring-permit caps; annual vs "2026-2027" specialty term) are published side by side. State requirements are not the complete story for any locality.
03 Trade → license
Relations below are recorded per state — only this jurisdiction's classifications are shown.
Trades involved: no seeded components — trade resolution follows from the classification relations below.
- Component basis ONSITE-WASTEWATER-INSTALLER — Individual and Small On-site Wastewater System (Septic) Installer (SD Plumbing Commission) confirmed S-SD-PLUMBING-LICENSING rule SD-PLB-EXAMA rural addition that is NOT on a public sewer needs the Commission's individual and small on-site wastewater (septic) installer licence — a Commission occupation with a $50 application and $105 annual installer fee, $100 exam (rule SD-PLB-EXAM). This is the page's South Dakota-specific credential.
- Alternative path ELECTRICAL-CONTRACTOR — Electrical Contractor (SD Electrical Commission) confirmed S-SD-WIRING-BULLETIN rule SD-ELEC-LICENSENew circuits and lighting for the addition need the electrical Commission licence (no threshold) — or the owner's exemption if the addition is the owner's own new single-family dwelling they will occupy (SDCL 36-16-15(3), permit first). There is NO state GC licence to hold for the addition itself: local permit + the 2% excise licence fill that layer (rules SD-NO-GC, SD-EXCISE on this page).
- May require PLUMBING-CONTRACTOR — Plumbing Contractor (SD Plumbing Commission) confirmed S-SD-PLUMBING-DEFAULT rule SD-PLB-LICENSEAn addition's new fixtures need the plumbing licence stack (contractor/plumber, no threshold) — and where the addition includes a new OWNER-OCCUPIED single-family dwelling, the homeowner paths (36-16-15(3) wiring, SDCL 36-25-17 plumbing) may apply with their permits (rule SD-PLB-LICENSE).
04 Scope
What the official sources say about the work involved — typed assertions, never a boolean "covers". Interpretations are marked as such.
- Officially included ELECTRICAL-CONTRACTOR Contract Electrical Work Of Any Kind (may_perform) SDCL 36-16-13, 36-16-14 S-SD-WIRING-BULLETIN The only class that may contract electrical work of any kind (rule SD-ELEC-CONTRACTING).
05 Requirements
| Requirement | Kind | Statement | Source |
|---|---|---|---|
| No statewide general contractor licence exists (verified absence) DLR Boards & Commissions list (dlr.sd.gov, read 2026-10-09) + DOR excise page | license | South Dakota issues NO general contractor, builder or construction-licence credential at state level. Evidence assembled from three official machine-read sources (2026-10-09): (1) DLR's own boards list shows every occupational board it directs — Abstracters, Athletic, Accountancy, Barber, Technical Professions, Cosmetology, ELECTRICAL, PLUMBING, Real Estate — with NO construction contractor board; (2) the only state construction-trade licences are electrical (SDCL ch. 36-16) and plumbing (SDCL ch. 36-25); (3) the Department of Revenue frames the state credential a construction contractor needs as the contractor's EXCISE TAX licence — 'Any person entering into a contract for construction services … must have a South Dakota contractor's tax license.' | S-SD-BOARDSSource S-SD-BOARDS — South Dakota Department of Labor and Regulation (DLR)DLR — Boards & Commissions under the direction of the South Dakota Department of Labor and Regulation (the absence evidence) — DLR Boards & Commissions list (dlr.sd.gov, read 2026-10-09) + DOR excise page https://dlr.sd.gov/boards_commissions_councils.aspx Retrieved 2026-10-09 · last verified 2026-10-09 Machine-read 2026-10-09 (HTTP 200). Lists every occupational/professional licensing board DLR directs: Abstracters' Board, Athletic Commission, Board of Accountancy, Board of Barber Examiners, Board of Technical Professions, Cosmetology Commission, ELECTRICAL Commission, PLUMBING Commission, Real Estate Commission — plus Banking, Human Rights, advisory councils and 'Other occupational and professional licensing boards and commissions, including those not under DLR'. NO general/building/roofing/HVAC contractor board exists. Together with the two trade chapters and DOR's excise page this is the evidence base for REQ-SD-NO-GC-LICENSE-001 and REQ-SD-NO-TRADE-LICENSE-001 (both confidence 'reported' — an assembled absence, never a gap). |
| Plumbing work requires a State Plumbing Commission licence (all seven occupations) SD Plumbing Commission front page (dlr.sd.gov, read 2026-10-09) | license | The Commission's front page verbatim (machine-read 2026-10-09): it 'Licenses all qualified plumbers, sewer and water installer, appliance installers, manufactured and mobile home, underground irrigation installers, water conditioning installers, and individual and small on-site wastewater system (septic) installers within the state,' and 'Administers the state laws and regulations concerning plumbing, sewer and water, appliance installation, manufactured and mobile home, underground irrigation, and water conditioning.' The licensing page enumerates the licence families (contractor/plumber/third-year/apprentice + six specialty families). SDCL 36-25-17 is titled 'License required for plumbing work on property connected to public water or sewer system — Exceptions' (official chapter index, surfaced), and the Homeowner Plumbing page quotes it as the homeowner exception. Violation of ch. 36-25 is a Class 2 misdemeanor per § 36-25-30 (rule cross-reference, surfaced — see REQ-SD-PLB-PENALTY-001). | S-SD-PLUMBING-DEFAULTSource S-SD-PLUMBING-DEFAULT — South Dakota State Plumbing Commission (within DLR)South Dakota Plumbing Commission — home (duties, occupations licensed, annual Dec 31 expiry) — SD Plumbing Commission front page (dlr.sd.gov, read 2026-10-09) https://dlr.sd.gov/plumbing/default.aspx Retrieved 2026-10-09 · last verified 2026-10-09 Machine-read 2026-10-09 (HTTP 200).

| Owner's exemption: wire your own residence/farmstead — but the permit comes FIRST DLR Homeowner Wiring page (dlr.sd.gov, read 2026-10-09) + SDCL 36-16-15 | exemption | SDCL 36-16-15 verbatim (official Wiring Bulletin, read 2026-10-09): 'No license is required of a person installing electric wiring in or on: (1) The person's own residence, including attached or unattached accessory structures and the parcel of land upon which the structures are situated; (2) The person's own farmstead; (3) The premises of a single-family dwelling unit that is in the process of being constructed if the person owns the premises and intends to occupy [it] …; or (4) The premises of any private, non-habitable property owned by the person …' — but 'Entrance installations in excess of sixty amperes capacity, circuits, or the installation of electrical parts of other apparatus shall be subject to inspection and payment of an inspection fee,' and 'Failure to report this work as required by law is a Class 2 misdemeanor'; 'residence' means a detached owner-occupied single-family dwelling. The Commission's Homeowner Wiring page adds: the owner's exemption (rule 20:44:14:01(12)) requires an approved HOMEOWNER PERMIT BEFORE starting any electrical work, proof of ownership, no commercial/rental property, mobile/modular only on an owner-occupied lot (otherwise a licensed electrical contractor must wire it), 72-hour inspection notice, rough-in + final inspections, and a permit life of three years. | S-SD-ELEC-HOMEOWNERSource S-SD-ELEC-HOMEOWNER — South Dakota State Electrical Commission (within DLR)SD Electrical Commission — Homeowner Wiring (the owner's exemption, permit-first rule) — DLR Homeowner Wiring page (dlr.sd.gov, read 2026-10-09) + SDCL 36-16-15 https://dlr.sd.gov/electrical/homeowner_wiring.aspx Retrieved 2026-10-09 · last verified 2026-10-09 Machine-read 2026-10-09 (HTTP 200).

SDCL 36-25-17 is titled 'License required for plumbing work on property connected to public water or sewer system — Exceptions' (official chapter index, surfaced — the chapter's full text sits behind sdlegislature.gov's JavaScript shell). The Commission's licensing page (machine-read) enumerates exactly which occupations require licences: plumbers, plumbing contractors, third-year apprentices, sewer and water installers, appliance installers, manufactured and mobile home installers, underground irrigation installers, water conditioning installers, and individual and small on-site wastewater system installers. The Commission's front page states the licence is issued by the State Plumbing Commission; violating SDCL 36-25 is a Class 2 misdemeanor (SDCL 36-25-30, surfaced — confidence `reported`, no dollar/day figures read).

09 Rule: SD-NO-GC
Verified absence: South Dakota issues NO statewide general contractor licence. The DLR boards list (machine-read 2026-10-09) names every occupational board the department directs — Abstracters, Athletic, Accountancy, Barber, Technical Professions, Cosmetology, Electrical, Plumbing, Real Estate — and no construction contractor board exists; the only two construction trades licensed by the state are electrical (SDCL ch. 36-16) and plumbing (SDCL ch. 36-25); DOR's own page frames the credential every South Dakota construction contractor holds as the contractor's EXCISE TAX licence. Confidence `reported`: an absence assembled from three official sources, not a single statute reciting 'no general contractor licence'. A caller reporting an 'SD general contractor licence' holds an electrical or plumbing credential, the excise tax licence, or a municipal licence.
