How do I find out how a piece of property is zoned?

Call the planning and zoning department in the city which the property is located. Ask them if a greenhouse is an acceptable use for the zoning. Also check the city ordinance (its usually online) and that should help as well.

Contact your local municipality City or county depending where the property is located to inquiry about the land use and zoning. Typically the planning or zoning department. many agencies will provide GIS information such as mapping to verify land use and Muni codes of ordinaces will describe each zoning code to full detail inclusive of what type of business is allowed, special uses height and setbacks of the types under the code. Fit your greenhouse within the required setback limits.

Local zoning ordinance is probably online. Look at zoning map and permitted uses for the zone. Also look at the conditional uses for the zone to see if greenhouses are listed. Mostly likely not listed. thus - meet with zoning officer at town for ruling.

Most municipalities allow horticultural uses in residential areas. It may depend on the intensity of activity. What kind of greenhouse are you pretending to build? size? etc. What is the pretend business you had in mind?
