Missouri, Perry County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas

Perry County, Missouri Remodeling and Renovation Permit Requirements

Information regarding building permits in Perry County, Missouri, particularly for unincorporated areas, can be complex due to varying local regulations. It is crucial to confirm specific requirements with the relevant authorities before commencing any work.

1. Authority Having Jurisdiction (AHJ)

The primary AHJ for building and safety in Perry County appears to be the Perry County Planning and Zoning Department for unincorporated areas, which issues Improvement Location Permits. For properties within city limits, the respective city's building department or inspector serves as the AHJ. For instance, the City of Perryville has a Building Inspector/Zoning Administrator. It's important to note that Missouri permits are generally administered at the local level.

2. Rules for Properties in Unincorporated Areas

In unincorporated areas of Perry County, the Planning and Zoning Department issues Improvement Location Permits for structures that are erected, constructed, reconstructed, moved, converted, or enlarged. Permit fees vary, and construction must commence within one year and be completed within two years of permit issuance. Before a residential structure is permitted in these areas, a sewage disposal system must be approved by the Perry County Health Inspector. An improvement location permit is required before occupying or using vacant land, occupying or using a structure that has been constructed, reconstructed, moved, or enlarged, changing the use of a structure or land, or changing a nonconforming use. The jurisdiction of the Perry County Plan Commission and Zoning Appeals covers all unincorporated land within Perry County, extending beyond two miles from the corporate limits of any city or town.

It is noted that the unincorporated areas of Perry County do not have zoning ordinances.

3. Permit Triggers for Demolition Work During a Remodel

Demolition work during a remodel generally requires a permit. The City of Perryville, for example, has a specific "Building Demo Permit" application. For demolition projects, specific requirements may include:

The Missouri Department of Natural Resources also regulates demolition and renovation projects and requires notification at least 10 working days before a project begins, especially if asbestos is involved.

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 typically requires a building permit. Depending on the scope of work, electrical, plumbing, or mechanical permits may also be necessary.

Key considerations and potential requirements for such conversions include:

It is recommended to consult with the local building department or planning and zoning office early in the planning process to understand all applicable requirements and to ensure compliance with zoning and building codes.

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.
