Idaho Falls, Idaho Remodeler Local Permit Ordinances and Codes
Idaho Falls Municipal Permit Ordinances for Remodelers and Home Renovations
The City of Idaho Falls Building Division is the Authority Having Jurisdiction (AHJ) for building permits and related ordinances within the city limits. They adopt and enforce the International Building Code (IBC) and the International Residential Code (IRC), 2018 Editions, with modifications as specified in their city code.
Permit Triggers: Demolition vs. Standard Residential Building Permit
A distinct demolition permit is generally required for any project involving the removal of part or all of a structure, including significant interior demolition that alters structural components. While there isn't a universally defined trigger, common situations requiring a demolition permit include major structural changes, such as removing load-bearing walls, relocating significant plumbing or electrical systems, or altering a building's footprint. Full or partial removal of a garage also typically requires a permit. For standard residential building permits, any owner or authorized agent intending to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure, or to install or replace any electrical, gas, mechanical, or plumbing system, must obtain the required permit.
Certain minor renovations may be exempt from requiring a building permit. These can include cosmetic bathroom updates without electrical or plumbing changes, replacing light fixtures or outlets with the same type, and replacing an existing driveway in the same footprint. However, it is always advisable to consult with the Building Division to confirm specific requirements for any project.
Space Alterations: Converting Non-Living Spaces to Habitable Areas
Converting non-living spaces such as basements or garages into habitable areas typically requires building, electrical, and mechanical permits. Zoning ordinances also play a role, as garage conversions may trigger specific occupancy requirements. It is essential to review local zoning regulations, which may include requirements for setbacks and lot coverage, before undertaking such conversions.
Fee Nuances and Inspection Stages
Permit fees in Idaho Falls vary based on the project's valuation. For example, the estimated fee range for detached garages over 120 sq ft is $135–$450, while attached garages range from $180–$630. Converting a garage to living space can range from $180–$720. A general permit issuance fee of $30.18 is also noted.
Inspections are a critical part of the building permit process, and no inspections can be made until the required permits are issued. Working without a required permit can result in double fees being assessed for the project. The City of Idaho Falls uses Cityworks software for permit applications, fee payments, and scheduling inspections.

Because Idaho Falls is located within Bonneville County, the following broader county regulations may also apply to your project:
Idaho, Bonneville County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Bonneville County, Idaho Remodeling and Renovation Permit Requirements
In Bonneville County, Idaho, the Building & Safety Division acts as the Authority Having Jurisdiction (AHJ) for building permits and inspections. This division is responsible for ensuring that all construction and renovation projects comply with state and local building codes. For properties located in unincorporated areas of Bonneville County, the same permit requirements enforced by the Building & Safety Division apply as they do for incorporated areas within the county.
Demolition Work During Remodels
Permit requirements for demolition work during a remodel in Bonneville County depend on the scope of the demolition. Generally, any demolition that involves the removal of structural components or a significant portion of the building may require a separate demolition permit. It is advisable to consult directly with the Bonneville County Building & Safety Division to determine if a permit is needed for your specific demolition plans, as this can vary based on the extent of the work and potential safety or environmental concerns.
Converting Non-Living Spaces to Habitable Areas
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas in Bonneville County requires a building permit. This process typically involves a review of the proposed plans to ensure compliance with building codes related to structural integrity, insulation, ventilation, egress (emergency exits), electrical, and plumbing. The definition of a "habitable space" generally refers to any area within a building designed for sleeping, living, or cooking. Specific requirements will be detailed during the permit application process, and inspections will be conducted at various stages of construction to verify code compliance.
- Definition of Habitable Space: Areas intended for living, sleeping, eating, or cooking.
- Permit Triggers: Any alteration that changes the use or occupancy of a space to a habitable one.
- Required Inspections: Typically include framing, insulation, electrical, plumbing, and final inspections.

The following statewide building codes and regulations apply universally to all jurisdictions within Idaho:
Idaho Remodeler Legislation, Codes, and Guidelines
Idaho Building Codes for Remodelers and Residential Renovations
Idaho's building codes and legislation for remodelers and residential renovations are primarily governed by the International Code Council (ICC) standards, adopted and enforced at the state level. The state has adopted specific editions of these codes, which form the basis for regulations concerning new construction and alterations to existing structures.
1. Adopted State Statutes and Codes
- Idaho has adopted the 2021 International Building Code (IBC) and the 2021 International Residential Code (IRC).
- The state also adopts the 2021 International Energy Conservation Code (IECC), the 2021 International Mechanical Code (IMC), the 2021 International Plumbing Code (IPC), and the 2021 International Fire Code (IFC).
- Crucially for renovations, Idaho has adopted the 2021 International Existing Building Code (IEBC). This code is specifically designed to address repairs, alterations, additions, and changes of occupancy in existing buildings.
2. Primary State Board or Agencies
- The primary state agency responsible for setting and enforcing building codes in Idaho is the Division of Building Safety (DBS), under the Department of Labor.
- The DBS is responsible for adopting, administering, and enforcing building codes throughout the state, including those related to residential renovations and remodels. They also oversee the licensing of contractors and inspectors.
3. Classification of Remodels and Demolition Guidelines
The 2021 IEBC provides the framework for classifying remodels and determining when demolition guidelines apply. Generally:
- Cosmetic Remodels: These typically involve minor changes that do not affect the structural integrity or life safety systems of the building. Examples include painting, re-carpeting, or replacing fixtures without altering plumbing or electrical systems. These often require fewer permits and inspections, though local ordinances may still apply.
- Structural Alterations: These involve changes that affect the building's structure, such as converting attics or basements into habitable living spaces, moving walls, altering load-bearing elements, or making significant changes to electrical, plumbing, or mechanical systems. These types of renovations generally require building permits and are subject to more rigorous plan review and inspections to ensure compliance with the adopted codes (IBC, IRC, IEBC).
- Demolition Guidelines: Demolition activities, whether partial or full, are also regulated. The IEBC and local ordinances will specify requirements for obtaining demolition permits, safety precautions during demolition, and proper disposal of debris. The extent of demolition and the potential impact on surrounding structures or public safety will dictate the specific guidelines and permits needed.
