Tips
- Green River's IRC design criteria (30 psf snow load, 115 mph wind, Seismic Category C, 42-inch frost depth, -20°F winter design temp) are unique to the city's elevation (6,132 ft) and climate — do not reuse Front Range Colorado or lower-elevation Wyoming city values.
- The Building Permit Application form requires you to state whether the property is in a Design Review District and/or Flood Plain — check both boxes carefully.
- Call ahead for approval status before making a trip to City Hall; the 14-working-day review target assumes a complete application.
- Green River's building permit review routes through Planning and Zoning, State/Fire (for certain project types), Building, and Engineering — budget time for multi-department sign-off.
