Don't get started on a home improvement project without checking to see if you need a building permit! Permits are required anytime you are changing anything that is structural, plumbing, or electrical. Stamped architect plans or a letter from a Structural Engineer are required when structural changes are being done. Starting a project without a permit can lead to work stoppage, money loss, and a lot of frustration. So, head over to the City of Darien's website for more information and applications
