You will need your ENGINEERED drawings that have been provided by Cascade Pole Buildings. Take these to the county office to apply for your permit as soon as possible. All counties require a PLOT map to go with the engineered drawings. Check with Cascade Pole Buildings and/or county official regarding how to draw the plot map.
Some counties will issue a permit in one day and some can take up to two years. When you turn in your permit, ask how long the average turn around time is so you can be prepared.
