South Dakota, Custer County Roofing Permit Regulations and County Ordinances for Unincorporated Areas

Roofing Permit Requirements in Custer County, South Dakota

In Custer County, South Dakota, the responsibility for building permits and code enforcement is divided between the county government and incorporated municipalities, such as the City of Custer. It is important to distinguish between these jurisdictions, as their requirements differ significantly.

Building and Safety Jurisdiction

Custer County, at the county level, does not have a comprehensive building code that requires permits for routine maintenance or repairs on existing structures. According to county guidelines, building permits are generally required for new construction, additions, and major structural changes, but they are explicitly not required for routine maintenance or the repair of damaged structures, provided the square footage of the building is not increased.

Conversely, the City of Custer maintains its own Building Department and Code Enforcement office. The City of Custer follows the International Building Code (IBC) and lists a "Roofing Permit" as part of its specific permit application offerings. If your property is located within the city limits of Custer, you must contact the City of Custer Building Department to determine if your specific roofing project requires a permit.

Rules for Properties in Unincorporated Areas

For properties located in the unincorporated areas of Custer County (outside of city limits), the following rules generally apply:

No General Building Code: Custer County does not enforce a general building code for residential roofing repairs or replacements.
Routine Maintenance Exemption: Routine maintenance, remodeling of existing structures, and the repair of damaged structures are exempt from the requirement for a building permit, provided there is no increase in the building's square footage.
State-Level Requirements: While the county may not require a permit for roofing, all construction must still conform to applicable South Dakota state codes and regulations, particularly those regarding electrical and plumbing installations if those systems are affected by the work.
Verification: Because regulations can change and specific property locations may have unique zoning or covenant restrictions, it is highly recommended to contact the Custer County Planning Department directly to confirm the status of your specific project before beginning any work.

State-Level Building Code Adoption in South Dakota

South Dakota does not enforce a single, uniform statewide building code for roofing or general construction. Instead, the state operates under a decentralized system where building codes are primarily adopted and enforced at the local level (cities and counties). Under South Dakota Codified Law (SDCL) Chapter 11-10, the state establishes the 2021 International Building Code (IBC) as the default design standard for jurisdictions that have not adopted their own local building code ordinances. Municipalities also have the authority to adopt the 2021 International Residential Code (IRC) to govern residential structures, including roofing requirements.

Primary Agencies and Oversight

Because building code enforcement is largely local, there is no single state board that sets or enforces roofing-specific standards for all projects. However, the following entities play roles in the broader regulatory framework:

Local Building Departments: These are the primary authorities for issuing permits, conducting inspections, and enforcing specific roofing codes (such as those found in the IBC or IRC) within their respective jurisdictions.
South Dakota Department of Public Safety (State Fire Marshal): The State Fire Marshal oversees fire safety standards and administers specific codes (such as the International Fire Code) that may impact building construction and safety, particularly for commercial or public facilities.
South Dakota Department of Revenue: While not a building code agency, this department is responsible for issuing the mandatory Contractor's Excise Tax License, which all contractors performing construction or repair work in the state must obtain.
