Non-compete laws in South Dakota: what you need to know

South Dakota restricts non-competes for a broad range of healthcare professionals, including physicians, physician assistants, chiropractors, dentists, and optometrists, among others. This extensive list of protected professions makes South Dakota one of the states with the broadest healthcare-specific non-compete protections.

For workers outside the protected healthcare professions, South Dakota relies on common law standards to evaluate non-compete enforceability. Agreements must be reasonable and protect a legitimate business interest. South Dakota courts have generally been willing to enforce reasonable non-competes in non-healthcare industries.

South Dakota is notable for allowing non-competes of up to two years, which is longer than the statutory maximum in some other states. Courts evaluate the duration as part of the overall reasonableness analysis, and agreements at or below two years are more likely to be deemed reasonable.

Workers in South Dakota should evaluate their non-compete against the traditional reasonableness standards. If you are a healthcare professional on the protected list, your non-compete is likely void. For other workers, the key factors are whether the agreement is narrowly tailored, reasonable in duration and geographic scope, and protects a genuine business interest.

South Dakota's broad list of protected healthcare professions is one of the most extensive in the country. Workers in any of the covered healthcare fields should be aware that their non-compete is likely void or significantly restricted. The specific list of protected professions is defined in the statute, and workers should verify whether their specific role is covered.

For non-healthcare workers in South Dakota, the common law framework applies. Courts evaluate non-competes for reasonableness, with a focus on whether the restriction is proportional to the employer's legitimate interest. South Dakota's allowance of non-competes up to two years is longer than some states, but agreements at or near that limit will face closer scrutiny.

For non-healthcare workers in South Dakota, the two-year maximum duration means that career disruption from a non-compete, while significant, has a defined end point. Workers should plan career transitions with this timeline in mind. If your non-compete restricts you for two years, understanding when the clock starts (typically from the date of separation, not the date of signing) and planning your next steps accordingly can help minimize the impact on your career and finances.
