Greene County, Alabama Plumbing Permit Requirements

In Greene County, Alabama, plumbing permits are generally required for the installation, alteration, repair, or replacement of plumbing systems. The specific requirements and jurisdiction can vary, especially between incorporated and unincorporated areas.

County-Level Jurisdiction and Building Safety Divisions

Greene County, Alabama, does not appear to have a centralized "Building & Safety Division" explicitly listed for general building permits in the same manner as some other counties. However, the Greene County Commission oversees various departments that handle aspects of development and infrastructure.
For plumbing permits, the jurisdiction often falls under the purview of the county engineer or a designated department responsible for infrastructure and development.
It's crucial to identify the correct county department responsible for issuing plumbing permits, as this can be managed by different offices depending on the specific nature of the work and the location within the county.

Rules for Properties in Unincorporated Areas

For properties located in unincorporated areas of Greene County, the county government typically holds the primary jurisdiction for issuing permits, including those for plumbing.
While Alabama state law (Ala. Code § 22-26-5) previously addressed permits for plumbing installations outside municipal corporations, this section was repealed in 2016. This suggests that current regulations are primarily handled at the county level.
It is essential for property owners in unincorporated areas to directly contact the Greene County Commission or its relevant departments to ascertain the precise requirements for obtaining a plumbing permit. This may involve submitting plans, undergoing inspections, and adhering to specific codes.
The Greene County Commission's directory lists departments such as the County Engineer/Highway Department, which may be involved in overseeing infrastructure-related permits.

Note: It is always recommended to contact the Greene County Commission directly to confirm the most current and specific plumbing permit requirements for your project, as regulations can be subject to change and may have specific nuances based on the type of work and location.

Plumbing Codes and Legislation in Alabama

Alabama does not utilize a single, mandatory statewide building code for all construction. Instead, building regulation is largely handled at the local level, with cities and counties choosing whether to adopt and enforce specific codes. However, the state does maintain standards for certain projects and professional licensing.

For projects under the jurisdiction of the Alabama Division of Construction Management (DCM), the state has adopted the 2021 International Plumbing Code (IPC). Additionally, the Alabama Plumbers and Gas Fitters Examining Board mandates that certified plumbing contractors comply with the 2021 International Plumbing Code for commercial installations and the 2021 International Residential Code (IRC) for residential plumbing installations, particularly in the absence of locally adopted codes.

Primary State Boards and Agencies

Alabama Plumbers and Gas Fitters Examining Board: This board is responsible for the statewide licensing, examination, and regulation of plumbers and gas fitters under the authority of the Alabama Plumbing and Gas Fitters Act (Code of Alabama § 34-37).
Alabama Division of Construction Management (DCM): Part of the Alabama Department of Finance, this division adopts and enforces building codes (including the IPC) for state-owned or state-funded projects.
Local Building Departments: In most jurisdictions, local municipal or county building departments are responsible for administering permits, conducting inspections, and enforcing the specific codes adopted by their local governing bodies.
Alabama Department of Public Health (ADPH): This agency oversees regulations regarding private sewage disposal systems and well connections.
