South Dakota does not test or license general contractors, builders, or remodelers at the state level. Statewide competency licensing in construction covers only electrical work (State Electrical Commission, SDCL ch. 36-16) and plumbing (State Plumbing Commission, SDCL ch. 36-25). A general contractor must sub those trades to licensees.
What the state does require is tax registration: every contractor whose receipts come from realty improvement contracts needs a contractor's excise tax (CET) license from the Department of Revenue and owes 2% on gross receipts, including owner-furnished materials (SDCL 10-46A-1, -4, -15). Materials are bought tax-paid at the state rate, 4.2% now and 4.5% from July 1, 2027 under SDCL 10-45-2. Local governments can and do layer on their own licensing and permits.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
South Dakota has no state contractor license for this trade, so cities and counties are free to add their own contractor licensing, registration, and permit rules. State law requires contractors to post their DOR contractor's excise tax license number with the building permit for a realty improvement project (SDCL 10-46A-12.1), and SDCL 10-46A-11 authorizes a municipal contractors' excise tax of up to one-half percent. Electrical and plumbing licensing remain statewide, though both chapters allow stricter local rules (SDCL 36-16-35, 36-25-16).
The local offices section below names the exact permit desk for every South Dakota county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
The DOR license proves you are registered to pay the contractor's excise tax; it says nothing about competence, and no exam is involved.
SDCL 10-45-2 sets the state sales and use tax at 4.2% now and 4.5% effective July 1, 2027 — budget materials for jobs that run past mid-2027 accordingly.
CET applies to the value of materials the owner supplies, and the contractor owes use tax on them if the owner can't show tax was paid.

Each item names the issuing authority, cycle, and citation.
Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Engaging in business subject to the contractor's excise tax without obtaining the license is a crime; so is failing to file returns or pay the tax within 60 days of the due date.
Keeping on without a license after DOR notifies you in writing that you are a contractor subject to the tax (unless you apply within three days), or working after revocation, is a felony.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.
Every fact in this file was checked against these official sources on October 2026.
Pending verification: That DOR charges no fee to issue a contractor's excise tax license — SDCL 10-46A-16 says a license is valid 'without further payment of fees' and the January 2026 CET guide lists no fee, but neither states expressly that issuance is free · Municipal contractor licensing, registration, or bonding in Sioux Falls, Rapid City, and other South Dakota cities (outside the scope of this state-level record) · Whether any municipality currently levies the local contractors' excise tax of up to one-half percent authorized by SDCL 10-46A-11
