Permit Requirements for Lennon, Michigan
For home remodeling and renovation projects in Lennon, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Shiawassee 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 Shiawassee County:
- Within City Limits: The Lennon Building Department typically oversees all Lennon building, trade, and safety permits.
- Unincorporated Areas: Properties located outside of official Lennon boundaries are generally governed by the Shiawassee 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 Michigan, 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.

Permit Triggers for Demolition Work During a Remodel
Demolition work during a remodel in Shiawassee County requires a Demolition Permit, which is obtained through the Zoning Administrator. To apply for a demolition permit, you will need:
- A completed Zoning Permit Application with a notarized "Affidavit of Compliance."
- Proof of Ownership (recorded land contract, deed, or tax billing statement with a full legal description).
- A Plot Plan showing property dimensions, setbacks, and the location of structures, utilities, well, and septic systems.
- Soil Erosion & Sedimentation Review from Shiawassee Environmental Health.
- A performance bond may be required, not exceeding $1,000 for each 1,000 square feet of floor area to be razed.
Separate permits are also required for electrical, plumbing, heating, ventilating, or air conditioning work associated with the demolition or remodel.
Permit Requirements for Altering or Converting Non-Living Spaces
A building permit is required to convert non-living spaces such as garages, attics, or unfinished basements into habitable living areas. Depending on the scope of work, separate electrical, plumbing, or mechanical permits may also be necessary. It is recommended to meet with the Development Services Center (DSC) staff early in the planning process to discuss zoning and building issues.
Key considerations for these conversions include:
- Existing Conditions: Unfinished areas may not meet current building code requirements for ceiling height, windows, stairs, or insulation.
- Living Space Minimums: Living space generally must have at least 70 square feet of floor area, with specific ceiling height requirements (at least 6'8" for basements).
- Egress: Basements with living space and sleeping rooms must have at least one egress window or exterior door. Egress windows should have a sill height of 44 inches or less.
- Insulation: New or existing insulation must meet current code requirements.
- Garage Conversions: You may need to demonstrate how a required on-site parking space will be provided.
- Doors: Doors leading into converted spaces must be at least 6'2" high and 30 inches wide.
Meeting with DSC staff is crucial to evaluate the feasibility and understand the specific code requirements for your unique conversion project.

The following statewide building codes and regulations apply universally to all jurisdictions within Michigan:
Michigan Remodeler Legislation, Codes, and Guidelines
Michigan Remodeling and Residential Renovation Building Codes
Michigan's building codes are primarily governed by the Stille-DeRossett-Hale Single State Construction Code Act (Public Act 230 of 1972). This act mandates statewide enforcement of construction codes to standardize building methods and requirements. The state adopts and amends model codes published by the International Code Council (ICC) and the National Fire Protection Association (NFPA).
1. Specific State Statutes and Codes Adopted
- Michigan has adopted the 2021 editions of the International Residential Code (IRC), International Building Code (IBC), International Mechanical Code (IMC), International Fuel Gas Code (IFGC), and International Energy Conservation Code (IECC), effective February 4, 2024.
- The Michigan Electrical Code is based on the National Electrical Code (NEC), with the 2023 NEC adopted.
- The state also utilizes the Michigan Rehabilitation Code for Existing Buildings, which addresses renovations and improvements to existing structures.
- Specific codes for residential renovations include the Michigan Residential Code (MRC), which is based on the International Residential Code (IRC) with state-specific amendments.
- The Michigan Rehabilitation Code for Existing Buildings is also relevant for renovations.
2. Primary State Board or Agencies
- The Michigan Department of Licensing and Regulatory Affairs (LARA), specifically the Bureau of Construction Codes (BCC), administers and enforces the statewide construction code.
- Local units of government (cities, villages, townships, and counties) also have the authority to enforce construction codes within their jurisdictions.
3. Classification of Remodels and Demolition Guidelines
- Cosmetic vs. Structural Alterations:
- Cosmetic renovations generally refer to aesthetic improvements that do not alter the structural integrity of the building. This can include painting, replacing fixtures, or updating finishes.
- Structural alterations involve modifying or reinforcing load-bearing components such as walls, foundations, floors, and roofs. These changes are more complex and often require professional design and engineering.
- Converting attics or basements to habitable living spaces typically involves structural changes and requires compliance with specific code requirements for egress, ceiling height, and fire safety.
- Any changes to load-bearing walls or structures require approval and must meet specific standards.
- Demolition Guidelines:
- A building permit is generally required for the demolition of a residential structure, especially for structures over 200 sq. ft., in-ground pools, or any portion of a house.
- Before demolition begins, an engineering survey must be conducted by a competent person to assess the structure's condition, potential impact on adjacent structures, and utility services.
- Demolition work must be performed safely, starting from the top and proceeding downward, with measures to protect adjacent properties and public access.
- Utility services must be disconnected and sealed by the relevant companies before demolition commences.
- Specific regulations apply to the removal of hazardous materials, such as asbestos, which may require specialized training and licensed contractors.
