Do I need a permit for interior remodeling in Downers Grove?
Most likely yes. Interior remodeling usually requires a permit in Illinois. Confirm the specifics with Downers Grove.
Interior remodels that move walls or alter electrical, plumbing, or mechanical systems require a permit in Downers Grove. Simple cosmetic finishes may not; confirm the scope with Community Development. Trade work triggers separate applications, such as the Electrical Application, and licensed contractors registered with the Village. Illinois publishes no statewide list of work exempt from a residential building permit, so the line is drawn by your municipality or county. Most Illinois jurisdictions treat purely cosmetic work such as painting, flooring, cabinets and countertops as exempt, while moving walls or altering electrical, plumbing or mechanical systems requires a permit. Confirm the local threshold before you start. Plumbing changes must be performed by an Illinois-licensed plumber under the statewide Illinois Plumbing Code, which is one of the few residential requirements Illinois does set at state level. A remodel that moves walls or includes electrical, plumbing, or mechanical work falls outside cosmetic exemptions, which cover finishes such as paint, flooring, trim, and cabinets. Each trade normally needs its own permit and inspection on top of the building permit, and removing or altering a load bearing wall usually requires a beam detail or engineering before the work is approved. Opening walls in an older home can trigger separate lead paint, asbestos, and smoke alarm requirements, so raise those with your department at application time.
