Except as may otherwise be provided in this Code, no Building Permit shall be issued for a Lot unless such Lot has the Area, width, and depth as required, and Frontage on a Street shown as a private or Public Street on the Streets Master Plan, or on a private easement connecting the Lot to a Street shown on the Streets Master Plan. 

All Development activity must comply with the following minimum Lot and Site requirements:

1. LOT SIZE. The minimum Lot Area is 1,875 square feet for a Single Family Dwelling and the maximum Lot Area is 3,750 square feet. The minimum Lot Area is 3,750 square feet for a Duplex and the maximum Lot Area is 7,500 square feet. For properties platted as lots within the historic Park City Survey and originally platted as 25 foot wide 75 foot deep with a lot size of 1,875 square feet, the Planning Director may make a determination that the minimum Lot Size may be reduced up to 20 square feet if subsequent surveys find that the final lot dimensions are less than 25 feet by 75 feet. The Footprint shall be reduced in accordance with the Lot Size and no variation to setbacks will be allowed.
2. LOT WIDTH.
   The minimum width of a Lot is twenty five feet (25'), measured fifteen feet (15') back from the Front Lot Line. In the case of unusual Lot configurations, Lot width measurements shall be determined by the Planning Director.
   
3. BUILDING ENVELOPE (HR-1 DISTRICT). The Building Pad, Building Footprint and height restrictions define the maximum Building envelope within which all Development must occur, with exceptions as allowed by Section 15-2.2-3.
   
4. BUILDING PAD (HR-1 DISTRICT).  The Building Pad is the Lot Area minus required Front, Rear, and Side Setback Areas.
   
   1. The Building Footprint must be within the Building Pad. The Building Pad must be open and free of any other Structure except:
      
      1. Porches or decks with or without roofs;
         
      2. At Grade patios;
         
      3. Upper level decks, with or without roofs;
         
      4. Bay Windows;
         
      5. Chimneys;
         
      6. Sidewalks, pathways, and steps;
         
      7. Screened hot tubs; and
         
      8. Landscaping.
         
   2. Exceptions to the Building Pad Area, excluding Bay Windows, are not included in the Building Footprint calculations, and are subject to Planning Director approval based on a determination that the proposed exceptions result in a design that:
      
      1. provides increased architectural interest consistent with the Design Guidelines for Historic Districts and Historic Sites;
         
      2. maintains the intent of this section to provide horizontal and vertical Building articulation.
         
5. BUILDING FOOTPRINT (HR-1 DISTRICT). The maximum Building Footprint of any Structure located on a Lot or combination of Lots, not exceeding 18,750 square feet in Lot Area, shall be calculated according to the following formula for Building Footprint. The maximum Building Footprint for any Structure located on a Lot or combination of Lots, exceeding 18,750 square feet in Lot Area, shall be 4,500 square feet; with an exemption allowance of 400 square feet, per Dwelling Unit, for garage floor area. A Conditional Use permit is required for all Structures with a proposed footprint of greater than 3,500 square feet.
   
   Accessory Buildings listed on the Park City Historic Sites Inventory that are not expanded, enlarged or incorporated into the Main Building, shall not count in the total Building Footprint of the Lot.
   
   MAXIMUM FP = (A/2) x 0.9^A/1875
   
   Where FP = maximum Building Footprint and A= Lot Area. 
   
   Example: 3,750 sq. ft. lot: (3,750/2) x 0.9^(3750/1875) = 1,875 x 0.81= 1,519 sq. ft.
   
    
   
   
6. FRONT AND REAR SETBACKS. Front and Rear Setbacks are as follows:
   
   TABLE 15-2.2a
   

   Lot Depth	Minimum Front/Rear Setback	Total of Setbacks
   Up to 75 ft., inclusive	10 ft. each	20 ft.
   From 75 ft. to 100 ft.	12 ft./13 ft. (or vice versa)	25 ft.

7. FRONT SETBACK EXCEPTIONS. The Front Setback must be open and free of any Structure except:
   
   1. Fences, walls, and retaining walls not more than four feet (4') in height, or as permitted in Section 15-4-2, Fences and Retaining Walls. On Corner Lots, Fences more than three feet (3') in height are prohibited within twenty-five feet (25') of the intersection, at back of curb.
