Yurt Design Criteria

Yurt Design Criteria Considerations



  • 2009 International Building Code
  • Pertinent local amendments?
  • Other pertinent codes?
Site Location
  • Address or Latitude, Longitude, Elevation
  • Site plan or survey drawings
  • Site description: flat, steep slope, waterfront, exposed site, sheltered,
  • Soils information
  • Other special conditions
Anticipated Yurt Usage
  • Full-time, part-time,
  • Heated or unheated?
Snow Loads
  • Ground snow load in psf (pounds per square foot)
Wind Speed
  • Wind speed in mph (miles per hour for a 3-second gust)
  • Wind Exposure
  • Exposure B.  Urban and suburban areas, wooded areas or other terrain with numerous closely spaced obstructions having the size of single-family dwellings or larger.  Exposure B shall be assumed unless the site meets the definition of another type of exposure.
  • Exposure C.  Open terrain with scattered obstructions, including surface undulations or other irregularities, having heights generally less than 30 feet (9144 mm) extending more than 1,500 feet (457.2 m) from the building site in any quadrant.  This exposure shall also apply to any building located within Exposure B-type terrain where the building is directly adjacent to open areas of Exposure C-type terrain in any quadrant for a distance of more than 600 feet (182.9 m).  This category includes flat open country, grasslands and shorelines in hurricane-prone regions.
  • Exposure D.  Flat, unobstructed areas exposed to wind flowing over open water (excluding shorelines in hurricane-prone regions) for a distance of at least 1 mile (1.61 km).  Shorelines in Exposure D include inland waterways, the Great Lakes and coastal areas of California, Oregon, Washington and Alaska.  This exposure shall apply only to those buildings and other structures exposed to the wind coming from over the water.  Exposure D extends inland from the shoreline a distance of 1,500 feet (460 m) or 10 times the height of the building or structure, whichever is greater.
  • Soil Site Class, if known (A, B, C, D, E, F)
  • Seismic Use Group category (I, II, III, IV)
  • Seismic Design Category (A, B, C, D)
Building Department Information
  • Building department contact information
  • Brochures or written instructions
  • Other special instructions/requirements from building department
Other Design Needs
  • Deck and foundation design
  • Interior platform floor and foundation
  • Other site buildings
