Most homeowners want to do their own renovations. This gives them a sense of pride and accomplishment, not to mention allows them to save some money.
This is all good, as long as the homeowner got all the necessary permits. Most homeowners aren't aware of all the permit requirements, or that certain work requires not only municipal permits, but also inspections by BC Safety Authority.
