•   Can I put a taco stand on any street corner?
•   I have weeds, what should I do?

No, you need to talk to the Davis County Health Department (the link to their page is here:

Then, you need to find a place of business who will allow you to put it in their parking lot.

Additionally, you need to comie into City Hall and talk to Stacey Steckler. Stacey's direct number is: 801-936-3877, x 108

Each spring season brings a crop of weeds that continues through the summer and fall months. As the fall season approaches, weeds and grasses dry up and increase the risk of fire and rodent harborage. However, another risk is beginning to be recognized by several people and agencies—the threat of noxious and invasive weed species.

North Salt Lake's ordinance require all weeds to be cut and maintained at a height not exceeding six (6) inches. By doing so, the risk of fire, rodents and invasive weeds can be reduced. To help in this effort, the Code Enforcement Officer of North Salt Lake is responsible for the enforcement of the weed ordinance. When he receives a complaint, he makes an on-site visit to verify the violation. He then contacts the owner of the property by mail to inform him/her of the violation and instruct them to cut the weeds. A reasonable amount of time is given the property owner to do so. If the owner complies, the problem is resolved for now. However, weeds continue to grow and they may require two or three cuttings during the season. If the owner does not comply, the Code Enforcement Office will contract with a weed cutting contractor to cut the weeds. A bill for the weed cutting and administrative costs will then be sent to the property owner by certified mail. If the owner does not pay that bill, a copy of the costs along with certification that the property owner has been notified will be sent to the County Treasurer with a request to have the amount placed as a lien against the property.
