That's especially true when planning a home improvement project - big or small.
It didn't take long for homeowner Maureen Dunlap to figure out something was wrong after her new furnace was installed.
Dunlap says, "It was held together with some duct tape or furnace tape and a flimsy board. When the furnace came on, the walls would suck in and I knew that wasn't right."
She called a different contractor for a second opinion and that contractor found a number of code violations.
HVAC contractor Alan Winters says, "Most common code violations we find are breakers are too large for the appliance that they are serving. In some cases, the wiring is not sized properly and a breaker is a point of contact so if something goes wrong that's supposed to give out first to protect the home, protect the equipment and everything."
Angie Hicks, the creator of the website, Angie's List, says, "If you ignore code violations in your home you might find that you face financial fines as well as legal ramifications."
Many contractors offer code violation correction work. You can also contact your local code enforcement agency if you are unsure whether you have an issue. If something is up to code when you put it in and then that code changes, you don't have to make any changes, but it might still be a good idea from a safety standpoint. Also, many homeowners' insurance policies won't cover damage or loss to an area that is not up to the current code.
