Do we have to depreciate our shed asset for LLC partnership or can we use section 179 deduction?

My sister and I started an LLC partnership in 2017 to run our clothing business.  We built a shed in her backyard that is used 100% for the business.  Do we have to depreciate the cost over the course of 27.5 years or can we elect the section 179 deduction for this asset?  We only spent around $5,000 to build it.
