If you are doing external work, you must submit a plat of survey of the property indicating what you are doing with distances from property lines and existing structures. Most work also requires drawings with all existing and new construction clearly marked including measurements. If you have a homeowner’s association, you must submit a copy of their written approval. If you are a tenant, you must submit written permission from the property owner. For more specific information on your project, contact the department at 815-741-5106.
