Permit Requirements for Martinsville, Illinois
For home remodeling and renovation projects in Martinsville, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Clark 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 Clark County:

- Unincorporated Areas: Properties located outside of official Martinsville boundaries are generally governed by the Clark 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.

Clark County Building & Safety Division
The Clark County Building & Safety Division is the Authority Having Jurisdiction (AHJ) for building permits and inspections within Clark County. They are responsible for ensuring that all construction and renovation projects comply with local building codes and safety regulations. The division offers services such as permit management, plan review, and on-site inspections. You can find permit application forms on their Citizen Access Portal.
Unincorporated Areas
For properties located in unincorporated areas of Clark County, building permit requirements generally apply as they would for other areas within the county. It is always recommended to confirm specific requirements with the Clark County Building & Safety Division, as regulations can sometimes vary.
Demolition Work During Remodels
Demolition work that is part of a larger remodel project may often be included and approved within the scope of the remodel permit itself. However, if the demolition is extensive, or if it involves specific elements like septic systems or electrical wiring, detailed plans may be required. In some cases, a separate demolition permit might be necessary, especially if the demolition is substantial or if it's a standalone activity. It's advisable to consult with the Building Department to determine the exact requirements for your specific demolition scope.
Converting Non-Living Spaces to Habitable Areas
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas typically requires a building permit. This process ensures that the converted space meets current building codes for safety and occupancy. Specific requirements often include:
- Minimum Ceiling Height: Habitable rooms generally require a minimum ceiling height, often around 7 feet, though some areas like bathrooms or utility rooms may have slightly lower allowances.
- Minimum Floor Space: A minimum floor area, frequently around 70 square feet, is usually mandated for habitable rooms.
- Egress Requirements: Adequate emergency exits are crucial. This typically involves having at least one egress window of a specified size and sill height, or an exterior door. Bedrooms often have stricter egress requirements.
- Insulation and Ventilation: Converted spaces must meet current code requirements for insulation and ventilation to ensure comfort and energy efficiency.
- Structural Considerations: Any structural modifications, such as adding or moving walls, or altering the roof structure, will require detailed plans and potentially engineering review.
- Electrical and Plumbing: New electrical wiring, outlets, lighting, and any new plumbing fixtures will likely necessitate separate electrical and plumbing permits.
- Parking: For garage conversions, some jurisdictions may require that you demonstrate provision for adequate on-site parking.
It is highly recommended to consult with the Clark County Building & Safety Division early in the planning process to understand all applicable requirements and to obtain the necessary permits before commencing work.

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.
