For properties within unincorporated Jefferson County, the Louisville Metro Government's Construction Review division is the relevant authority for building and safety permits.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Jefferson County, the Louisville Metro Government's Construction Review division oversees building and safety regulations. This includes the requirement for permits for new construction, additions, alterations, and certain trade work like electrical, mechanical/HVAC, and plumbing.
Plumbing permits themselves are issued by the Kentucky Department of Housing, Buildings and Construction, Division of Plumbing. This applies to both incorporated and unincorporated areas of Jefferson County. Homeowners can obtain plumbing permits for their personal residences, but all work must comply with the Kentucky State Plumbing Code and be performed by the homeowner or a licensed plumber.

Kentucky Plumbing Legislation, Codes, and Guidelines
Kentucky Plumbing Statutes and Codes
Plumbing in Kentucky is primarily governed by Kentucky Revised Statutes (KRS) Chapter 318, which establishes the legal framework for the practice of plumbing, licensing requirements, and the authority to promulgate the state plumbing code. The technical standards for plumbing installations, materials, and methods are set forth in the Kentucky State Plumbing Code, which is codified under 815 KAR Chapter 20 of the Kentucky Administrative Regulations.
Unlike some other building codes that may adopt a specific edition of the International Plumbing Code (IPC) by reference, the Kentucky State Plumbing Code is a distinct set of regulations developed and maintained by the state. While it incorporates industry standards, it is specifically promulgated by the state department to address local, climatic, and regulatory conditions within the Commonwealth.
Regulatory Agencies
The primary state agency responsible for the administration, oversight, and enforcement of plumbing standards and licensing in Kentucky is the Department of Housing, Buildings and Construction (DHBC), specifically through its Division of Plumbing. This division is responsible for:
- Issuing and renewing licenses for master and journeyman plumbers.
- Reviewing and issuing plumbing construction permits.
- Conducting inspections to ensure compliance with the Kentucky State Plumbing Code.
- Administering the state plumbing examination through the State Plumbers Examining Committee.
While the DHBC maintains state-level authority, certain local jurisdictions may be authorized to administer and enforce the state plumbing code within their boundaries, provided they adhere to state regulations and employ qualified inspectors.
