Permit Requirements for Highland, Illinois
For home remodeling and renovation projects in Highland, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Madison County.
Authority Having Jurisdiction (AHJ)
The governing body responsible for issuing building permits, reviewing plans, and conducting inspections varies depending on exactly where the property sits in Madison County:
- Within City Limits: The Highland Building Department typically oversees all Highland building, trade, and safety permits.
- Unincorporated Areas: Properties located outside of official Highland boundaries are generally governed by the Madison County Building & Safety Division.
Common Remodeling Permit Triggers
Remodeling is a broad category, and permit requirements depend heavily on the scope of your work. While cosmetic updates—such as painting, installing new flooring, or replacing like-for-like kitchen cabinets—generally do not require approval in Illinois, you will almost certainly need a permit for the following:
- Space Conversions: Altering non-living spaces (such as finishing a basement, finishing an attic, or converting a garage) into habitable living areas.
- Structural Changes: Removing, adding, or modifying load-bearing walls, headers, or the roofline.
- Demolition: Extensive interior renovations or "gutting" a space often requires a specific demolition permit prior to or concurrent with the standard building permit.
- Systems Alterations: Rerouting plumbing pipes, adding new electrical circuits, or moving HVAC ductwork.

Madison County Building & Safety Division
The Madison County Building & Zoning Department is responsible for administering and enforcing building codes within the county. They adopt and follow various International Codes, including the International Building Code, International Residential Code, and others, to ensure safe construction and occupancy of buildings. Permits are required before commencing any construction, and a building inspector will check progress at selected milestones.
Unincorporated Areas
For properties located in unincorporated areas of Madison County, the Building & Zoning Department administers the International Building Code.
Demolition Permit Triggers
A demolition permit is required for all structures that are demolished and/or removed from their current location. The review process for a demolition permit can take a minimum of ten working days after all required documents are submitted. Landfill receipts are mandatory for all waste removed from the demolition site.
Converting Non-Living Spaces to Habitable Areas
Converting spaces like garages, attics, or unfinished basements into habitable living areas generally requires a building permit. This is because such conversions often involve changes that impact the building's structure, safety, and occupancy. Specific requirements may include:
- Garages: Converting a garage into living space typically requires permits for building, electrical, and plumbing work. It may also necessitate upgrades to insulation, ventilation, and accessibility features to meet code requirements for habitable rooms. The garage is usually considered non-habitable space initially, meaning it may have limited requirements for insulation or ventilation.
- Attics and Basements: Remodeling or altering basements generally requires a permit. For basements, specific requirements like egress windows are crucial, especially if the bottom of the window is below ground level. These windows must meet minimum size and height/width requirements for emergency escape.
It's important to note that specific definitions and requirements can vary, and it is always best to consult directly with the Madison County Building & Zoning Department for precise guidance on your project.

The following statewide building codes and regulations apply universally to all jurisdictions within Illinois:
Illinois Remodeler Legislation, Codes, and Guidelines
Illinois State Building Codes and Legislation for Remodelers and Residential Renovations
Illinois has recently enacted significant changes to its building code structure, aiming for statewide uniformity. As of January 1, 2025, Public Act 103-0510 mandates that all municipalities and counties must adopt building codes that meet the minimum standards set by the International Code Council (ICC). This includes the International Building Code (IBC), the International Existing Building Code (IEBC), and the International Residential Code (IRC). Local governments have until June 1, 2025, to ensure their codes align with these statewide requirements. For jurisdictions that have not adopted a building code, builders and homeowners must still adhere to a "baseline" code, which aligns with ICC standards from the 2018, 2021, or 2024 editions. Areas with existing codes must ensure their standards are at least as stringent as those established by the ICC within the last nine years.
The primary state agencies involved in setting and enforcing these standards include the Illinois Capital Development Board (CDB), which oversees the statewide code implementation, and the Illinois Department of Financial and Professional Regulation (IDFPR), which provides guidance for building code enforcement officials and design professionals.
For residential renovations, the International Residential Code (IRC) is generally applicable. The International Existing Building Code (IEBC) is relevant for alterations, repairs, and additions to existing structures. While the state has not adopted a specific statewide building code for repairs to existing single-family residences, local Authorities Having Jurisdiction (AHJs) may regulate these repairs.
The Illinois Home Repair and Remodeling Act (HRRA) provides consumer protections for residential projects. This act requires a written contract for any home repair or remodeling work exceeding $1,000, detailing the total cost, parts, materials, and contractor information. For projects costing $1,000 or less, contractors must provide a "Home Repair: Know Your Consumer Rights" pamphlet.
Generally, cosmetic remodels that do not alter the structure or systems of a building may not require permits. However, structural alterations, such as converting attics or basements to habitable spaces, removing load-bearing walls, or significant electrical or plumbing updates, typically require permits and adherence to building codes.
Demolition guidelines in Illinois involve obtaining necessary permits from local authorities and potentially the Illinois Environmental Protection Agency (IEPA), especially if hazardous materials are involved. Specific requirements for demolition permits, including timelines and recycling of construction debris, can vary by municipality. For instance, Chicago requires a demolition permit for altering a building that permanently reduces its area.
