4.Identify the scope and applicability of the 2018 Georgia Plumbing Code and its relationship to the 2018 Georgia Gas Code.
5.Distinguish between the roles and responsibilities of the master plumber, journeyman plumber, and the local code official (Authority Having Jurisdiction, AHJ).
6.Apply the correct permit, inspection, and approval processes for plumbing and gas work in Georgia.
7.Interpret the legal authority, penalties, and enforcement provisions that govern plumbing work.
8.Navigate the code structure to locate administrative, definitional, and technical requirements efficiently during the exam.
1.1 The Foundation: Code Adoption and Legal Framework
The 2018 Georgia Plumbing Code is based on the 2018 International Plumbing Code (IPC), with specific state amendments. Similarly, the 2018 Georgia Gas Code is based on the 2018 International Fuel Gas Code (IFGC). Both are adopted under the authority of the Georgia Construction Industry Licensing Board, Division of Master and Journeyman Plumbers.
Key point for the master exam: The code is not merely a technical manual—it is a legally enforceable regulation. The master plumber is the responsible licensed individual for all work performed under their license. This means you are accountable for code compliance, permit accuracy, and the actions of journeymen and apprentices under your supervision.
Scope of the Plumbing Code (IPC Chapter 1):
The code applies to the erection, installation, alteration, repair, relocation, replacement, addition to, or use of any plumbing system.
This includes: sanitary drainage, storm drainage, venting, water supply, and fixtures.
The Gas Code (IFGC Chapter 1) applies to fuel gas piping, appliances, and venting.
Georgia-specific amendment: The state has not adopted the optional appendices of the IPC unless specifically referenced. You must know which appendices are enforceable—typically, none are mandatory unless the local jurisdiction adopts them.
1.2 The Authority Having Jurisdiction (AHJ)
The AHJ is the local building official, plumbing inspector, or code enforcement officer. Their duties include:
Receiving and reviewing permit applications.
Conducting inspections at required stages.
Issuing approvals or notices of violation.
Maintaining records of permits and inspections.
Master-level responsibility: The code gives the AHJ the authority to interpret the code and to approve alternative methods or materials if they are deemed equivalent. However, the burden of proof for equivalency rests on the applicant—you, the master plumber. If you propose an alternative design, you must provide technical documentation, test data, or engineering analysis.
Exam trap: The AHJ does not have the authority to waive code requirements. They can only approve alternatives that meet the intent of the code. A waiver is a legislative act, not an administrative one.
1.3 Permits: When Required and When Exempt
General rule (IPC Section 101.2 and Chapter 1): No plumbing system shall be erected, altered, or repaired without a permit. This applies to both residential and commercial work.
Exemptions from permit (typical Georgia amendments):
Minor repair work involving the clearing of stoppages or the replacement of faucets or valves where no alteration of the piping occurs.
Replacement of an existing fixture with a similar fixture, provided the work does not involve changes to the drainage or supply piping.
Emergency repairs, provided a permit is obtained within a specified time (often 48 hours or the next business day) after the work is performed.
Exam trap: The exemption for "minor repairs" does not include replacing a water heater, rerouting a drain, or adding a fixture. Those require a permit. Also, a permit is required for rough-in work even if the final connection is not made.
Permit application requirements:
Name and address of the owner or the licensed master plumber.
Description of the work and location.
Plans and specifications as required by the AHJ (for commercial or complex work).
Payment of fees.
Georgia-specific requirement: The permit application must be signed by the master plumber of record. This is a legal attestation that the work will comply with the code. If the work is performed by a journeyman, the master plumber is still the responsible party.
1.4 Inspections and Approvals
Required inspections (IPC Chapter 1):
47.Rough-in inspection: All drainage, venting, and water supply piping must be inspected before being covered or concealed.
48.Final inspection: After the system is complete and all fixtures are installed, the AHJ conducts a final inspection.
Additional inspections (as required by the AHJ):
Underground inspection (before backfilling).
Water supply pressure test.
Backflow prevention device testing (must be performed by a certified tester).
Gas piping pressure test (under the Gas Code).
Notice of inspection: The permit holder (or the master plumber) must notify the AHJ when work is ready for inspection. The AHJ has a reasonable time (often 24–48 hours) to respond. Work shall not proceed beyond the inspection point until approval is granted.
Exam trap: If the AHJ fails to inspect within the required time, the work may proceed at the risk of the permit holder. This does not mean you are automatically approved—if a later inspection reveals noncompliance, you must correct it.
Testing requirements (IPC Chapter 1 and Chapter 7):
Drainage and vent systems must be tested with water or air. Water test: 10 feet of head (or the highest point of the system), minimum 30 minutes. Air test: 5 psi for 15 minutes.
Water supply systems must be tested at 1.5 times the working pressure, minimum 100 psi, for 15 minutes.
1.5 Violations and Penalties
Enforcement provisions:
The AHJ has the authority to issue a stop-work order for any work that is being performed without a permit or in violation of the code.
Occupancy of a building shall not be permitted until final approval is granted.
Penalties for violations are set by local ordinance and state law. For a licensed master plumber, violations can result in fines, suspension, or revocation of the license.
Master-level responsibility: You are not only liable for your own actions but also for the actions of those you supervise. If a journeyman under your license performs defective work, you are held accountable. This is a critical legal distinction—the license is a public trust.
1.6 Definitions: The Language of the Code
The exam will test your understanding of code terminology. Key definitions from IPC Chapter 2 that you must know cold:
Plumbing system: Includes the water supply and distribution pipes, fixtures, traps, soil, waste and vent pipes, and all connections to the public sewer or private disposal system.
Drainage system: Piping that carries sewage or other waste to a point of disposal. Does not include the vent system.
Vent system: Piping installed to provide a flow of air to or from a drainage system to protect trap seals.
Trap: A fitting or device that provides a liquid seal to prevent the passage of air or gas.
Fixture: A receptacle or device that is supplied with water or receives wastewater.
Indirect waste pipe: A pipe that discharges into a receptor without a direct connection.
Backflow: The flow of water or other liquids into the potable water supply from any source other than the intended source.
Cross-connection: Any physical connection between the potable water supply and any other substance or source.
Gas Code definitions (IFGC Chapter 2):
Fuel gas: Natural gas, liquefied petroleum gas (LP-gas), or manufactured gas.
Appliance: Any device that utilizes fuel gas to produce heat or power.
Vent: A passageway for conveying flue gases to the outdoors.
Exam trap: The code distinguishes between a drainage system and a sanitary drainage system. The latter specifically carries sewage. Storm water is handled separately (Chapter 11 of the IPC). Do not confuse them.
1.7 Code Navigation: Where to Find It

Georgia amendments: The state amendments are typically found in the front of the code book or in a separate supplement. They modify the base IPC text. For example, Georgia may adjust the required water supply fixture unit values or the minimum number of fixtures for certain occupancies. Always check the amendment section first when a question involves a specific number.
1.8 Practical Field Points for the Master Plumber
89.Permit posting: The permit must be posted on the job site and be accessible to the inspector. Failure to post is a common violation.
90.Scheduling inspections: Do not cover any piping until the rough-in inspection is approved. This is the #1 cause of failed final inspections and costly rework.
91.Pressure test records: Keep a written log of all pressure tests, including date, time, test pressure, and the names of witnesses. This protects you in a dispute.
92.Backflow prevention: As a master plumber, you are responsible for ensuring that all cross-connections are eliminated. This includes not only code-required devices but also field-identified hazards.
93.Gas work coordination: Gas piping and plumbing are often inspected by the same AHJ, but they are separate codes. A gas test is distinct from a water test—do not combine them.
1.9 Common Exam Traps
Trap 1: "The AHJ approved it, so it's legal." False. The AHJ cannot waive code requirements. Approval of an alternative does not set a precedent for other projects.
Trap 2: "A journeyman can pull a permit." False. Only a licensed master plumber can pull a permit for plumbing work in Georgia. A journeyman works under the master's license.
Trap 3: "Emergency repairs don't need a permit." Partially true. You may perform the repair immediately, but you must obtain a permit retroactively within the time specified by the local jurisdiction.
Trap 4: "The plumbing code covers gas piping." False. Gas piping is covered by the Georgia Gas Code (IFGC). The plumbing code only covers water, drainage, and venting. However, a master plumber is often licensed to install both.
Trap 5: "A water test and an air test are interchangeable." False. The code specifies when each is acceptable. An air test is not allowed on systems that will be subjected to water pressure until the system is fully charged.
1.10 Summary
The administrative chapter is the foundation of your legal and professional obligations. You must know:
The scope of the code and what triggers a permit.
The inspection sequence and testing requirements.
The limits of AHJ authority.
The definitions that govern all other chapters.
The distinction between the plumbing code and the gas code.
A master plumber is not just a technician—they are a licensed professional accountable to the public and the state. The administrative provisions are where that accountability is defined and enforced. Master this chapter, and the rest of the code becomes easier to navigate.
