Do I need a permit for interior remodeling in Highland Park?
Most likely yes. Interior remodeling usually requires a permit in Illinois. Confirm the specifics with Highland Park.
Highland Park requires a permit for most interior remodeling that changes walls, plumbing, electrical, or mechanical systems, including kitchen and bathroom remodels and basement finishing. Purely cosmetic work such as painting or flooring generally does not need a permit. Confirm your scope with the Highland Park Building Division. Plumbing changes must be done by an Illinois state-licensed plumber and electrical work by a state-licensed electrical contractor registered with the City. A homeowner performing their own work may need to sign the Homeowner as General Contractor agreement. Basement or lower-level work near a ravine or in a flood-prone area can carry extra drainage and grading requirements, so ask the City before you start. 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.
