Looking to purchase a land or warehouse around Houston

I looked at redfin har zillow and loopnet but this information is never included in descriptions.

Basically what I am trying to understand is which neighborhoods have commercial zones or mixed zones. Obviously if the land is designated for residential, I can not build a warehouse there but where do I look to see if a land for sale is commercial or mixed?

Ft Bend or harris county appraisal websites do not have this info either.

Also, if it turns out to be mixed, does it mean I can build a house and a warehouse in the same land?
