Minnesota, Hennepin County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Hennepin County Building & Safety Division
Hennepin County's Building & Safety Division acts as the Authority Having Jurisdiction (AHJ) for building permits in unincorporated areas of the county. For properties within incorporated cities, the respective city's building department is the AHJ. It is crucial to identify the correct AHJ for your specific location before starting any renovation project.
Unincorporated Areas
In Hennepin County, unincorporated areas are subject to the county's building codes and permit requirements. This means that if your property is not within the boundaries of an incorporated city, you will need to work directly with the Hennepin County Building & Safety Division for all permit-related matters.
Demolition Permit Triggers
Demolition work during a remodel in Hennepin County typically requires a permit. Specific triggers include:
- Full or partial demolition of structural elements.
- Removal of load-bearing walls.
- Demolition that may affect the building's structural integrity or safety.
- Any demolition involving hazardous materials, such as asbestos or lead paint, will have additional specific requirements and may necessitate specialized permits and licensed contractors.
It is always recommended to consult with the Hennepin County Building & Safety Division to determine the exact permit requirements for your specific demolition scope.
Permit Requirements for Non-Living Space Conversions

Minnesota Remodeler Legislation, Codes, and Guidelines
Minnesota State Building Codes and Legislation for Remodelers and Residential Renovations
In Minnesota, the regulation of building codes and residential renovations falls under the purview of the Minnesota Department of Labor and Industry (DLI), specifically its Construction Codes and Licensing Division (CCLD). The state has adopted various codes, primarily based on the International Code Council (ICC) series, to ensure safety and quality in construction and remodeling projects.
1. Specific State Statutes and Codes Adopted
Minnesota has adopted the 2020 Minnesota State Building Code (MSBC), which includes several key components relevant to residential renovations:
- International Building Code (IBC): Minnesota Rules, Chapter 1305 adopts the 2018 IBC.
- International Residential Code (IRC): Minnesota Rules, Chapter 1309 adopts the 2018 IRC. This code is particularly relevant for one- and two-family dwellings and townhouses.
- International Existing Building Code (IEBC) Equivalents: Minnesota Rules, Chapter 1311 pertains to the "Rehabilitation of Existing Buildings." While not a direct adoption of the IEBC by year, this chapter addresses alterations, repairs, and additions to existing structures, ensuring they meet accessibility standards and other safety requirements.
- Other Relevant Codes: The MSBC also incorporates other codes such as the Minnesota Plumbing Code (Chapter 4714), Minnesota Energy Code, and Minnesota Accessibility Code.
2. Primary State Board or Agencies
The Minnesota Department of Labor and Industry (DLI), through its Construction Codes and Licensing Division (CCLD), is the primary state agency responsible for promulgating and administering construction-related codes and licensing laws. This division oversees the enforcement of health and safety codes for both new and existing structures.
3. Classification of Remodels and Demolition Guidelines
Minnesota's building codes generally distinguish between cosmetic and structural alterations. While the codes do not explicitly define "cosmetic remodel" versus "structural alteration" in simple terms, the need for permits and adherence to specific code sections is triggered by the scope of work:
- Cosmetic Remodels: Minor updates like painting, replacing flooring, or updating fixtures typically do not require permits unless they involve work on electrical, plumbing, or mechanical systems.
- Structural Alterations: Projects involving framing, altering load-bearing walls, converting spaces like attics or basements into habitable areas, or significant changes to the building's structure will require permits and must comply with the relevant sections of the IRC and other applicable codes. For instance, finishing a basement or converting an attic into living space involves specific requirements for ceiling height, emergency egress, insulation, and ventilation.
Demolition Guidelines:
- Demolition permits are generally required for the demolition of residential and commercial structures.
- Before demolition or renovation, especially for structures built before 1978, there are requirements for identifying and removing hazardous materials, including asbestos. The Minnesota Pollution Control Agency (MPCA) has specific guidelines and notification requirements for demolition projects.
- A pre-demolition inspection may be required by local authorities, such as Ramsey County, to ensure proper removal and disposal of hazardous waste.
- If demolition is part of a larger renovation project, a separate demolition permit may not be necessary if there is no significant delay between demolition and new work, provided the remodel permit application includes details about the materials to be removed.
- Contractors performing demolition must comply with state and local regulations, including proper waste disposal and management.
