A structure enclosed and used for the cultivation or protection of tender plants. In municipal zoning code, greenhouses are considered an accessory structure. A hoop house is a more temporary and easily transported structure that serves a similar purpose.
Note: Under the MN Green Acres program (Statue 271.111, Subdivision 3 https://www.revisor.mn.gov/statutes/cite/273.111), the presence of a greenhouse may qualify an agricultural site to meet its requirement for significant tax reductions (through a three-year rolling deferment program that continues as long as the site continues to be used for agriculture).
