When it comes to remodeling a home, adding an extension or just doing some house upkeep, do you always need to get a permit taken out in order to do any construction work? I imagine if it's work inside the home, you can probably get away with not getting a permit, but anything on the outside of a home might require a permit correct? What if it's just repairing a door or window? I figure an extension or an add-on will require a permit, but small things don't. Right?
