The most challenging part of building a home is knowing what order to install the products and the details of the installations. Exteriors gives you step-by-step directions to build a house; this class starts by helping the student understand city permits and inspections. The idea is before you dive into building a home, you should check with the city before even purchasing land. Questions like, what are the building codes? How do I apply for the permits? Do I need a job site folder? What is the difference between load-bearing and non-load bearing walls? Even more is addressed with this program.
