Generally, a plumbing permit is required if you are altering the plumbing system of the bathroom by moving or adding water lines, installing or moving toilets, sinks, showers, bathtubs, water heaters, etc. An electrical permit may be needed if you are adding or moving lighting, installing new outlets, changing the electrical panel, etc. A building permit may also be required for more extensive bathroom renovations that involve altering the structure of the house.
To obtain the necessary permits, you will need to submit a permit application to the City of Chicago Department of Buildings. The application fee can vary depending on the scope of work and the permit required. You may also need to hire a licensed professional to prepare and submit the permit application on your behalf.
Homeowners are encouraged to contact the Department of Buildings for specific permit requirements and guidance before starting the bathroom remodeling project. The department can provide information about permits and inspections and ensure compliance with all applicable building codes and regulations.
