Summary

Iowa City requires a permit before any plumbing work under Title 17 of the City Code, which adopts the Iowa State Plumbing Code (Iowa Code section 105.4(1)(a)) as its governing standard. Only a licensed master plumber, a company employing one full time, or an owner-occupant of a detached single-family home may pull the permit.

Subject to the following amendments... the City further adopts, Section 10 ... 5.4(1)(a) of the Iowa Code (the Iowa State Mechanical Code and the Iowa State Plumbing Code). Collectively, they shall be known as the Iowa City Building Code or the Building Code. ... 105.9 (IBC) and R105.11 (IRC) Permittee: 1. An electrical, plumbing or mechanical permit may be issued to any person holding a valid master license for the respective trade as described in Section 17-11-1 of the Iowa City Code, or to any company who employs a duly licensed master in the respective trade on a full-time basis who supervises the work of the apprentice and or journeymen during the company's normal business hours. 2.

Full Breakdown

4(1)(a) to govern all plumbing systems inside city limits. Together these are known as the Iowa City Building Code, administered by the Building Official under the administrative provisions carried in Chapter 1 as amended. 11 of the IRC, adopted as local amendments in section 17-1-3, restrict who may obtain a plumbing permit: it can go to any person holding a valid master plumber license under section 17-11-1 of the City Code, or to a company that employs a full-time licensed master plumber who supervises apprentices and journeymen during normal business hours.

A narrow owner exception lets a homeowner of an owner-occupied, detached single-family dwelling pull an electrical, plumbing, or mechanical permit for that residence and its accessory structures, but the exception never extends to an apartment, a rental unit, or an apartment building, and it excludes an electrical dwelling service upgrade or replacement. Plan review is triggered separately once a project's value passes $15,000, and a refund of an erroneously collected fee must be requested in writing within 180 days of payment.

Violations & Fines

Doing plumbing work without the required permit, or letting an unlicensed person perform it, is a municipal infraction under section 17-1-4, punishable as set out in subsection 1-4-2D of the City Code. The Building Official can also order work halted, require correction before final approval, and withhold a certificate of occupancy until the permit and required inspections are complete.
