If you are planning to add a home addition or do any remodeling project this spring or summer, you first need to contact the Northlake Building Department. Many remodeling jobs require building permits. Depending on the job, you may even need some rezoning approval. Permits are required to insure that the building meets the minimum standard of safety assured by building codes. Also permits can guarantee that a contractor is bonded and the homeowner is protected from fraud. If you have any questions, please call 708-343-8700 and ask for the building department.
