Honolulu County Plumbing Permit Requirements

In Honolulu County, plumbing work generally requires a permit. This includes new installations, alterations, repairs, and replacements of plumbing systems, fixtures, and appliances. However, certain minor repairs, such as clearing stoppages or repairing leaks that do not involve replacing or rearranging pipes or fixtures, may be exempt. Additionally, replacing existing fixtures like faucets or sinks with similar ones in the same location for non-commercial residential use might not require a permit. For specific details on exemptions, it is advisable to consult the Revised Ordinances of Honolulu (ROH) Chapter 18-3.1.

Permits are typically obtained through the Department of Planning and Permitting (DPP). For projects that do not qualify for an "Instant Online Permit," plans may be required. These plans must meet specific formatting checklists and may need to be stamped and signed by a licensed professional if the work value exceeds certain thresholds or if the project is in a special management area or flood hazard area.

Electrical and plumbing repair work performed by a licensed contractor may be exempt from permit requirements if the cost does not exceed $2,500 within a 12-month period, provided it does not involve service entrance equipment for electrical work.

State-Level Plumbing Codes and Legislation in Hawaii

The State of Hawaii has adopted the Uniform Plumbing Code (UPC) as its statewide plumbing code. Specifically, the state has incorporated the 2018 edition of the Uniform Plumbing Code, published by the International Association of Plumbing and Mechanical Officials (IAPMO), into the Hawaii Administrative Rules (HAR) under Title 3, Chapter 183. This adoption includes specific state-level amendments to address local requirements, such as seismic support standards and definitions tailored to Hawaii's regulatory environment.

While the state establishes these minimum standards, the enforcement of plumbing codes is primarily handled at the county level. Each county in Hawaii may adopt the state code by ordinance and is responsible for issuing permits and conducting inspections for plumbing installations within its jurisdiction.
