Is there a difference between production and retail greenhouses?
Yes, the codes are very specific as to the usage of a greenhouse with respect to the general public. Fire code issues are an example of one of the major differences. A production house is defined as a greenhouse that is occupied for growing a large number of flowers and plants on a production basis or for research, without public access. A retail greenhouse is occupied for growing large numbers of flowers and plants while having general public access for the purposes of viewing and purchasing various products. Included in this category are greenhouses occupied for educational purposes.
