Permitting will not be needed in some areas, and in others, you will need architectural drawings and signed stamped engineered drawings. Either way, we seldom run into any issues getting our structures permitted. To start, email us to get a copy of the generic technical drawings and build manual so you can educate your permitting office on what an Arched Cabin is! This might be all you need. Our design is considered to be a permanent structure. Because the engineered snow loads etc. are determined by location, you would need to get engineered plans for your location to be 100% sure you meet requirements when required. However, we are very confident our structures will meet any requirements. The highest standard we have accomplished for wind was 165mph in Gulf Shores, Alabama. In Washington state, we received a 110 lbs PSF snow load rating. We have also achieved seismic ratings in San Bernardino County, California. We have engineer licenses in all 50 states that we work with that can get you started in this process if it is necessary for your location.
