Pole Barn /Accessory Building Restrictions  

It is important for home owners to understand that pole barns are generally NOT designed for 

residential family dwellings.  Problems occur when homeowners attempt to build or remodel 

a pole barn for a residential occupancy.  Issues with the foundation system, fire separation, 

plumbing and roof design may occur.  These issues can require costly alterations to bring the 

structure into compliance with the current building codes adopted by Laramie County.   

In addition, there may be land use regulations that prohibit a second residence or a residence 

created for a rental unit.  If the pole barn is built to be occupied as a residential dwelling it 

shall meet the requirements of the 2015 International Residential Code, shall be permitted 

with a residential permit and meet the requirements of the Laramie County Land Use 

Regulations. 

If you have any questions regarding permitting and the use of the pole barn structure please 

ask! 

I have read and understand that this application for an accessory structure does not meet the 

requirements of a family dwelling and will not be inhabited as a family dwelling.
