**2.7 Legal considerations**

When selecting and purchasing a site, there are various legal considerations. Permits, licenses, and zoning regulations govern where a greenhouse may be built and often even dictate what type of building materials may be used. Such considerations may also involve relevant mandates from the Occupational Safety and Health Administration that ensures employee safety. Selecting an appropriate site also involves how the greenhouse operation affects its neighbours (schools, hospitals, parks, farms or ecological areas, etc.).
