Overview

South Dakota sets its age of consent at 16. S.D. Codified Laws Section 22-22-1(5) makes it rape for sexual penetration with someone 13 through 15, but only where the perpetrator is at least three years older. Below that gap, this specific subdivision does not apply.

A separate statute, Section 22-22-7, covers sexual contact without penetration, and reduces the charge from a felony to a misdemeanor where the victim is 13 or older and the actor is less than five years older.

Close-in-age rules in South Dakota

South Dakota uses two different mechanisms depending on the type of conduct:

  • Sexual penetration, victim 13–15: not covered by Section 22-22-1(5) if the perpetrator is less than three years older. This is a true exemption from rape.
  • Sexual contact only, victim 13 or older, under 16: Section 22-22-7 reduces the charge from a Class 3 felony to a Class 1 misdemeanor if the actor is less than five years older, but the conduct remains a crime either way.
Neither allowance applies to a victim under 13. Section 22-22-1(1) makes any sexual penetration with someone under 13 rape in the first degree, the most serious class of felony under this statute, with no age-gap consideration.

Exceptions and defenses

Section 22-22-7 excludes the actor’s spouse from coverage. A subsequent conviction of either Section 22-22-1(5) or Section 22-22-7, following an earlier conviction under either, is enhanced to a Class 2 felony under Section 22-22-7.7, regardless of the original age gap.

Practical examples

These are simplified, hypothetical illustrations only, not legal advice, and not a prediction of any real case’s outcome.

Example 1. A 15-year-old and a 17-year-old, sexual penetration, a two-year gap. Because the gap is under three years, Section 22-22-1(5) does not reach this conduct.

Example 2. A 14-year-old and a 18-year-old, sexual contact only, a four-year gap. Because the gap is under five years, this is a Class 1 misdemeanor under Section 22-22-7 rather than the base felony.

Example 3. A 12-year-old and a 15-year-old, sexual penetration, a three-year gap. Because the victim is under 13, Section 22-22-1(1) applies regardless of the gap, the most serious class of felony.

Frequently asked questions about South Dakota

What is the age of consent in South Dakota?

16. S.D.C.L. Section 22-22-1(5) and Section 22-22-7 apply different gap thresholds for penetration and contact with a victim 13 through 15.

Does South Dakota have a Romeo and Juliet law?

Yes, in two forms. Penetration is not covered by rape if the gap is under three years. Contact-only conduct is reduced from a felony to a misdemeanor if the gap is under five years.

Is the contact allowance a full exemption?

No. It reduces the charge from a felony to a misdemeanor; the conduct remains a crime either way.

Does either allowance apply to a victim under 13?

No. A victim under 13 is covered by the most serious rape provision regardless of the age gap.

Are married couples treated differently?

Yes, for contact-only conduct. Section 22-22-7 excludes the actor’s spouse from coverage.
