Great question. Many people leave these up for months at a time. Some companies rent them out as glamping tents. Officially, they are designed for camping so the warranty won't cover extended use. The biggest threat is constant moisture, humidity, and rot. That can happen if it's set-up in an area where it doesn't dry out daily, but is just constantly wet, especially near the bottom where the floor and wall seam meet. If it is surrounded by grass or shrubbery that doesn't allow that to dry it will eventually rot. So, with that in mind, some people (especially businesses renting them out) leave them up for months at a time and replace them as needed. We had some customers in Hawaii that would put a canopy over them to protect it from long-term uv ray damage and they would often get a full year out of them. All the elements, but especially moisture, factor into how long it would last as a long-term shelter which, again, isn't covered under the warranty.
