Properties in Unincorporated Areas

For properties located in unincorporated areas of Howard County, the county building department typically handles permit review and issuance. It is essential to confirm whether your project falls under the jurisdiction of a specific city or the county. Howard County, Missouri, has a zoning map that outlines land use and development standards for unincorporated areas.

Permit Triggers for Demolition Work During a Remodel

Demolition permits are generally required for the removal of all buildings or structures. When undertaking a remodel that involves demolition, it is crucial to check with local city and county regulatory agencies, as local ordinances may be stricter than state regulations.

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, additional electrical, plumbing, or mechanical permits may also be necessary.

Garages: Converting a garage to living space may require demonstrating how a required on-site parking space will be provided. If the garage is detached, it may need to meet setback requirements, and if it's close to a property line, a fire wall might be necessary.
Attics: Attic conversions must meet minimum space requirements (e.g., 70 sq. ft. of floor space, at least 7 ft. in any direction, and at least half the floor space with a ceiling height of 7 ft. or more). A code-compliant staircase and a secondary means of egress (like an operable window) are also required.
Basements: Finishing or remodeling a basement to create living space requires permits for framing, electrical, and egress. A minimum ceiling height of 6'8" is generally required for basement living spaces. Egress windows or exterior doors are mandatory for basements with living space and sleeping rooms to ensure emergency escape.

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.
