Unofficial copy. It may be out of date. Not legal or zoning advice. Zoning rules change, and only the city or county can say for sure what is allowed on a property. Confirm with the city or county planning department before you buy, sign or build.

Confirm anything here with Tooele County planning before you rely on it.
Some nonconforming uses, such as mining or
gravel extraction must be expanded in order for the use to continue at all. Such businesses shall be allowed to expand without limitation or restriction to the immediate area excavated at the time the ordinance was passed regardless of the current zoning onto the rest of the property acquired for such a use. This shall not allow for the purchase of additional property with which to expand, but does allow that all property held at the time the more restrictive ordinance was passed can be used for the intended purpose.
