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

Scotland County, Missouri: Remodeling and Renovation Permit Requirements
Scotland County, Missouri, like other jurisdictions in the state, requires permits for various construction and renovation activities to ensure compliance with building codes and safety standards. Since Missouri does not have a statewide building code, local authorities having jurisdiction (AHJs) manage permit review and issuance. For unincorporated areas, county building departments typically handle these responsibilities. It is crucial to verify specific requirements with the Scotland County Planning and Zoning Department or the relevant county office, as local ordinances may be stricter than state regulations.
1. Authority Having Jurisdiction (AHJ)
In Scotland County, Missouri, the local authority responsible for building and safety regulations, including the issuance of permits, would typically be the county's building department or planning and zoning office. For unincorporated areas, the county government is the AHJ. It is advisable to contact the Scotland County Clerk's office or a designated county planning official to confirm the exact department and procedures for obtaining permits.
2. Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Scotland County, building regulations are generally managed at the county level. Missouri Revised Statutes § 65.677 grants township boards the power to regulate and restrict aspects of buildings in unincorporated portions of the township for the promotion of health, safety, and general welfare. However, these regulations typically do not apply to agricultural uses like farming, orchards, or forestry. It is essential to confirm with Scotland County officials whether specific zoning or building permit requirements apply to your property in an unincorporated area, as regulations can vary.
3. Permit Triggers for Demolition Work During a Remodel
Demolition work, even as part of a larger remodel, often triggers the need for a permit. In Missouri, demolition of existing structures is generally listed as a project requiring a building permit. Specific requirements for demolition permits may include:
- Notification to the Missouri Department of Natural Resources for asbestos testing and abatement, especially for older structures.
- A plot plan showing which structures will be demolished and which will remain, if multiple buildings are on the site.
- Compliance with local ordinances, which may be stricter than state regulations.
It is crucial to contact the Scotland County building department to understand the specific demolition permit requirements before commencing any demolition work.
4. Permit Requirements for Altering or Converting Non-Living Spaces
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas almost always requires a building permit. This is because these conversions involve structural changes and require the space to meet specific building codes for safety and occupancy. General requirements for such conversions include:
- Garages: Converting a garage into living space typically requires a building permit and may necessitate providing alternative parking if required by local ordinances. The conversion involves ensuring proper insulation, ventilation, electrical, and plumbing, and meeting egress requirements.
- Attics: Creating habitable space in an attic usually requires a permit. This involves meeting minimum ceiling height requirements (often around 7 feet for at least 50% of the space), minimum room dimensions, and ensuring adequate egress, such as a staircase and an egress window.
- Unfinished Basements: Finishing an unfinished basement to create living space requires a building permit. This includes meeting requirements for ceiling height (often a minimum of 7 feet), emergency escape and rescue openings (egress windows), smoke detectors, and proper electrical, plumbing, and mechanical installations.
In all cases of converting non-living spaces, detailed construction plans, site plans, and potentially contractor information will be required for the permit application. Electrical, plumbing, and mechanical permits may also be necessary depending on the scope of work.

The following statewide building codes and regulations apply universally to all jurisdictions within Missouri:
Missouri Remodeler Legislation, Codes, and Guidelines
Missouri State-Level Building Codes and Legislation for Remodelers and Residential Renovations
Missouri does not have a single, statewide building code. Instead, building codes are adopted and enforced at the local level by municipalities and counties. These local jurisdictions typically reference model codes from the International Code Council (ICC). The most commonly adopted versions of these codes in Missouri include the 2015 editions of the International Building Code (IBC), International Residential Code (IRC), International Existing Building Code (IEBC), International Plumbing Code (IPC), and International Mechanical Code (IMC). Some areas may also reference the 2009 International Energy Conservation Code (IECC) and the National Electrical Code (NEC), which are enforced locally. It is crucial for remodelers to verify the specific codes and any local amendments in effect with the local building department for their project's location. Some municipalities, like O'Fallon and Town and Country, have adopted the 2021 or 2024 editions of the International Existing Building Code, respectively.
The primary state board or agencies that set these standards are not centralized at the state level for building codes. Instead, the Division of Professional Registration supports various professional licensing boards and commissions responsible for regulating professions within the state. However, for building codes, enforcement and adoption are primarily handled by local building departments and officials.
Generally, the classification of remodels and when demolition guidelines apply are determined by local ordinances and the adopted building codes. The International Residential Code (IRC) and International Existing Building Code (IEBC) provide frameworks for alterations and repairs. Structural alterations, such as converting attics or basements to habitable spaces, typically require permits and are subject to more stringent requirements than cosmetic remodels. Demolition guidelines are also locally enforced and often require specific permits, advance notice to neighbors, and adherence to safety and debris removal protocols. For instance, some municipalities require a notice of intention to demolish to be sent to properties within 200 feet, and demolition must proceed continuously and be completed within a specified timeframe.
Missouri law broadly defines remodeling as any work that erects, demolishes, alters, or repairs improvements to a property. This includes kitchen and bathroom renovations, room additions, structural changes, and electrical, plumbing, and HVAC upgrades. For substantial renovations, Missouri statute defines it as modifications affecting at least fifty percent of the square footage of a building or costing at least fifty percent of the building's fair market value.
