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

Crawford County, Missouri Remodeling and Renovation Permit Requirements
Crawford County, Missouri, does not have a county-wide building codes program that requires a general building permit for all construction and renovation projects. However, permit requirements can vary significantly depending on whether a property is located within an incorporated city or in an unincorporated area, and specific project types may still necessitate permits. It is crucial to verify requirements with the relevant local jurisdiction before starting any work.
1. Authority Having Jurisdiction (AHJ)
In Crawford County, building permits are typically issued by individual city and town building departments. For properties in unincorporated areas, the county commission or a designated county department may be the authority. The Meramec Regional Planning Commission (MRPC) administers the county's floodplain management program.
2. Rules for Properties in Unincorporated Areas
For properties in unincorporated areas of Crawford County, a general building permit is not always required. However, a floodplain development permit may be necessary if the property is located within a floodplain. Some unincorporated areas may have township boards that regulate building, but this requires approval by a vote of the people. It is essential to confirm with the county commission or relevant county office for specific regulations pertaining to unincorporated areas.
3. Permit Triggers for Demolition Work During a Remodel
While specific demolition permit triggers for general remodeling are not explicitly detailed for Crawford County, state regulations require notification for asbestos abatement projects at least 10 working days before work begins. Additionally, Missouri state law (RSMo Chapter 319) mandates contacting Missouri One Call (811) at least two working days, but no more than ten, before any demolition or excavation to locate underground utilities. Local ordinances may impose stricter requirements, so checking with local city and county agencies is advised.
4. Permit Requirements for Altering Non-Living Spaces
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas generally requires a building permit. This is because these conversions often involve structural changes, electrical, plumbing, or mechanical work, and the converted space must meet current building code requirements for safety and occupancy.
- Garages: Converting a garage into living space typically requires a permit. This may involve demonstrating provision for required on-site parking, meeting setback requirements if detached, and ensuring structural integrity.
- Attics: Attic conversions to habitable space almost always require a permit. The space must meet minimum ceiling height (often 7 feet for at least 50% of the area), room dimensions (e.g., 70 sq. ft. floor space, 7 ft. width), and egress requirements (e.g., a full-size staircase and an egress window). Structural changes like adding dormers or altering roof structures will also necessitate permits.
- Unfinished Basements: Converting an unfinished basement into living space also requires a building permit. Minimum ceiling height (often 6'8"), egress windows or exterior doors for safety, and proper stairways are key requirements.

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.
