1st review:  Provide a written response to comments with revised plans.

1.  What specifically makes this a "U Occupancy"?   What will be stored in the building that you would call it a utility shed?  The facility looks like it is either a "S1 - Storage Warehouse or an S2 - Aircraft Hangar".  Correct code study where applicable.

2.  Provide an address on the building visible from the street fronting the property.  Show location on elevation sheet.

3.  Provide a Knox brand keybox at the main entrance mounted approximately 5 ft above grade.  Show location on elevation sheet.

4.  Show on plans size, type, & location of required fire extinguishers.  Placing one at each exit should mmet code.

5.  Show location and available fire flow from the closest hydrant.

6.  Indicate on the plans the intended fire access route between the hydrant and the building.  Are there any gates or fencing involved?  Hydrant distance is measured along the fire access road and depending on occupancy type is either 450 (If S1 or S2) or 600 ft (If U) maximum.

7.  Two exits are required since common path of travel exceeds both 75 ft and 100 ft as measured rectilineal.  Since two exits are required provide both exit signs and emergency lighting fixtures (EM's) as required per code.  Show locations on plans to include EM's at the exterior exit discharges.
