If you are referring to a stand-alone building, and not a prefabricated one, check with your local buildings codes. At a minimum it should be a block building, aluminum or fiberglass doors (including roll-ups), explosion proof electrical, mechanical and passive ventilation and no floor drains. All entry/exit points should have a 4" lip to contain spills within the building. Floor and 6" up the wall should be sealed using an epoxy product (certain states only allow certain products) and no wooden shelves. This building may also need to be a certain distance from any other occupied structure.
Fertilizers and chemicals will need to be stored in separate rooms with a fire wall in between. They may not allow you to store your sprayers in the same room, and therefore you may need another room dedicated to them.
When permitting, if you call this a chemical/fertilizer storage building, your local municipality may make you jump through a great number of hoops - including installing a dry fire extinguisher system. Save yourself a headache and build it with the above mentioned requirements and call it simply a "storage building".
