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

Ray County Building & Safety Division and Unincorporated Areas

In Ray County, Missouri, building permits are generally issued by individual city and town building departments. However, for properties in unincorporated areas, the Ray County Planning & Zoning Department serves as the authority having jurisdiction. It is crucial to confirm the specific requirements with the relevant city or county department before starting any construction project, as rules and fees can change.

Permit Triggers for Demolition Work During a Remodel

A Demolition/Relocation Permit Application is available through the Ray County Planning & Zoning Department. While specific triggers for demolition during a remodel are not detailed, it's important to note that demolition of existing structures generally requires a building permit in Missouri. For demolition projects, there are also state and federal regulations concerning asbestos-containing materials that must be followed, including notifying the Missouri Department of Natural Resources at least 10 working days before demolition begins.

Permit Requirements for 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.

Definition of Living Space: Living space must have at least 70 square feet of floor area. In areas with sloped ceilings, no more than half of the required floor area can have a ceiling less than 6'8" in height, with no part of the required area less than five feet in height. Basements designated as living space must have a ceiling height of at least 6'8".
Egress Requirements: Basements with living space and all sleeping rooms must have at least one egress window or exterior door for emergency escape. Egress windows in basements must have a sill height of 44 inches or less.
Door Dimensions: Doors leading into converted attics, basements, or garages must be at least 6'2" high and 30 inches wide. Exterior doors used for emergency escape must meet the same size requirements.
Garage Conversions: If converting a garage, you may need to demonstrate how required on-site parking spaces will be provided. Detached garages may also need to meet setback requirements, and if the exterior wall is less than three feet from a property line, a fire wall will be required.
Structural Integrity: For attic conversions, the existing attic floor structure must be strong enough to support the weight of people and furniture.
Permit Fees: The building permit fee for residential use is $0.40 per square foot of livable space, which includes finished basements, bonus rooms, and attics.

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.
