Full Breakdown
Texas prohibits all home cultivation of marijuana, and Richardson has no authority to override state law. Under Texas Health & Safety Code Chapter 481, marijuana remains a Schedule I controlled substance, and the Texas Compassionate Use Program (Occupations Code Chapter 169) only authorizes licensed dispensing organizations to grow low-THC cannabis. Cultivating even a single plant in a Richardson home is a criminal offense: possession of the plants and resulting usable marijuana is prosecuted by weight, starting at a Class B misdemeanor (up to 180 days jail) for under 2 ounces and escalating to a felony for larger amounts or when cultivation equipment suggests manufacture or delivery. Hemp (under 0.3% THC) is legal to grow only with a Texas Department of Agriculture license. Richardson code enforcement may also cite unpermitted indoor grow rooms for electrical and building code violations.
