My husband and I built a huge 3-car garage about four years ago. For the first three years, there was no electricity running to it because we didn't have the money or the knowledge to run the electric to it. Last year, we spent our extra money on having the garage hooked up to the electricity and learned how to run the wiring. Before the flip was switched for the first time, we had an electrician come out and inspect what we had done. We made many mistakes that are actually quite common for DIYers. Find out what they were here on our blog.
