South Dakota caps personal medical cannabis cultivation at three flowering plants per registered patient, with stricter household limits, applicable to Sioux Falls residences.
Under SDCL §34-20G-2, a qualifying medical patient authorized to grow may possess no more than three cannabis plants at one time, plus the cannabis those plants produce, kept securely at the registered residence. A designated caregiver may cultivate for up to five qualifying patients but limits stack within statute. Sioux Falls does not impose additional plant counts but does require code compliance for any modified electrical, ventilation, or lighting work. Building permits may be needed for substantial grow-room build-outs, and odor controls help avoid Chapter 80 nuisance citations.
Possessing more plants than authorized, sharing or selling home-grown cannabis, or operating a grow without provider authorization triggers state felony charges and city code enforcement.
