Lot Coverage

Lot coverage is the percentage of the total lot area covered by structures.  Structures not counted in measuring lot coverage are as follows:

• Structures less than 30 inches above the finished grade level (such as paved terraces or ground-level decks)
  
• Windowsills, bay windows, fireplace chases, belt courses, cornices, eaves, and similar incidental architectural features
  
• Accessibility ramps
  
• Fences, trellises, poles, posts, ornaments, lawn furniture, and similar custormary yard accessories
  
• Covered stairways and walkways that are roofed but not fully enclosed and are installed to provide public access between grade-separated areas, but not intended to provide access to any particular structure
  
• Ground floor porches running parallel to and projecting a minimum of four feet from the street facing facade of the building that is unenclosed or only partly enclosed up to a maximum of 200 square feet
