Step 1 of 4

What you are actually required to carry

Workers' compensation in South Dakota

Yes — South Dakota requires workers' compensation at 0 employees, and you are above that threshold.

Statutory threshold on file: 0 employees · Local municipal licensing (no statewide contractor license) · statutory citation and enforcement detail below

  1. Workers' Compensation

    Required by law

    Medical care and lost wages for employees injured on the job.

    Typical limits
    $100,000 – $1M

    Triggered by your state's employee threshold. Employers liability (Part B) limits are what contracts actually specify.

    • Workers' compensation is elective in South Dakota, but employers without it lose statutory defenses and most GCs require it.

  2. Commercial Auto Liability

    Required by law

    Liability for vehicles owned or used by the business.

    Typical limits
    $1M

    Any vehicle titled to the business or used primarily for business needs a commercial auto policy; a personal auto policy will deny a business-use claim. Contracts standardly require a $1M combined single limit.

  3. General Liability

    Required by contract

    Third-party bodily injury and property damage arising from your operations.

    Typical limits
    $1M – $2M

    No state requires general liability by statute, but essentially every client contract, lease and job-site agreement demands $1M per occurrence / $2M aggregate. Treat it as mandatory in practice.

    • Job-site work means you will be asked for additional insured (CG 20 10 / CG 20 37), primary and non-contributory wording, and a waiver of subrogation.

  4. Commercial Umbrella / Excess

    Required by contract

    Extra limit sitting above GL, auto and employers liability.

    Typical limits
    $1M – $5M

    General contractors and enterprise clients routinely require $2M–$5M of excess limit above the primary policies before they will let you on site.

  5. Tools & Equipment (Inland Marine)

    Strongly recommended

    Your own tools and portable equipment, on site or in transit.

    Typical limits
    $10,000 – $50,000

    General liability covers other people's property, never your own. Portable tools and equipment in vehicles or on site need an inland marine schedule.

  6. Installation Floater

    Situational

    Materials you have purchased but not yet installed at a job site.

    Typical limits
    $25,000 – $150,000

    Materials you have bought but not yet installed belong to you until acceptance. Builder's risk covers the structure, not your staged materials.

The law behind this in South Dakota

SDCL § 62-3-3

Who it reaches
Workers' compensation is elective by statute, but employers without it lose common-law defenses.
If you go without it
Operating without required coverage exposes the business to stop-work orders, civil penalties assessed per employee per day, personal liability for the full cost of an injured worker's medical care and lost wages, and loss of the statutory defenses that normally cap an employer's exposure. South Dakota Department of Labor and Regulation administers enforcement.
Vehicle liability minimums
25/50/25; commercial contracts typically demand $1M CSL

Prior claims, higher limits, added endorsements

  • Grading Contractor is rated elevated hazard; this drives the general liability base rate more than any other single factor.
  • Workers' compensation is the largest line item at your headcount — published benchmarks for construction run around $3,100 per covered employee before state adjustment.
  • Job-site work adds an umbrella requirement, which typically adds $600–$2,500 annually.
  • South Dakota prices commercial risk at an index of 86 against a national median of 100, so identical operations cost 14% less here.
  • Claims history, years in business and prior coverage continuity move the final number more than limit selection does.

Faulty workmanship discovered months after sign-off causes a substantial property loss at a client's premises. Completed-operations coverage inside your general liability policy responds to the repair and consequential damage claim.
