Additionally,as was discussed on September 22, 2021,please remember that the fence will need to have Knox key switch on the gate(if electronic)or a key box on the gate with a fire department key. As you requested, I have enclosed the City's building permit application and driveway permit application form. So long as you include all of the information required in the conditions of approval in your building permit submittal,you would not need standalone zoning or grading permits,though a separate driveway permit is still required.
