Plumbing Permit in Corpus Christi, Texas
Permit required
Yes, a permit is required
Before installing a water heater, adding water lines, connecting to sewer, extending or altering gas pipe, installing or replacing a drain or vent, or installing an irrigation system or backflow preventer, inside the Corpus Christi city limits

Quick answer
Corpus Christi requires a plumbing permit for water heater installation, added water lines, sewer connections, extending or altering gas pipe systems, installing or replacing a drain or vent, and installing an irrigation system or backflow preventer. Three jobs are published as not needing one: stopping and repairing leaks in drain or water pipes, clearing drain stoppages, and removing and reinstalling a plumbing fixture with no modifications. Homeowners may pull their own plumbing permit on their homestead with one hard exception, since new or altered natural gas service systems must be permitted and installed by a state licensed plumber. Rough-in, Top out and Final are the required inspections, with gas rough, gas final and backflow added depending on scope.
Typical threshold: A plumbing permit is needed to install a gas or electric water heater, add water lines, connect to sewer lines, extend or alter gas pipe systems, install or replace a drain or vent, or install an irrigation system or backflow preventer; stopping and repairing leaks, clearing drain stoppages, and removing and reinstalling a plumbing fixture without modifications are excluded.

How to apply in Corpus Christi
You apply for a residential plumbing permit at your local building department by filing an application that describes the scope of work and site, along with construction documents, before any regulated plumbing installation, alteration, or repair begins. Minor repairs that do not touch piping or fixtures are generally exempt, and once issued the permit only stays valid if work is started within its time limit.
What most plumbing permit applications include:
- A permit is required before any owner or authorized agent constructs, alters, repairs, removes, converts, or replaces a plumbing system regulated by the code (IRC R105.1).
- The application must identify and describe the work, describe the site, state the intended use and occupancy, and be signed by the applicant or an authorized agent (IRC R105.3).
- Two or more sets of construction documents must accompany the application, drawn with enough clarity to show the location, nature, and extent of the proposed plumbing work and how it will conform to code (IRC R106.1, R106.1.1).
- Minor plumbing repairs, such as clearing a stoppage or removing and resetting a water closet without rearranging pipes or fixtures, are exempt from permit (IRC R105.2).
- Once issued, a permit is only valid for a limited window, commonly 180 days, and becomes invalid if the work is not started or is abandoned within that time, though extensions can be requested (IRC R105.3.2, R105.5).

Inspections and closing out your permit
Plumbing inspections are timed to whatever is about to hide the pipe: underground and under-slab piping is checked before concrete covers it, rough-in piping is pressure or water tested before walls close up, and a final inspection checks every fixture and backflow protection once the work is complete.
- Piping and equipment placed under a slab or floor must be in place and inspected before any concrete is poured or floor sheathing is installed over it (IRC R109.1.1.1).
- Rough plumbing, along with the mechanical, gas, and electrical rough-in, must be inspected prior to covering or concealment and before fixtures or appliances are set (IRC R109.1.2).
- Rough drain, waste, and vent (DWV) piping is tested with water, air, or (for plastic piping) a vacuum, and must show no evidence of leakage before it is closed in (IRC P2503.5.1).
- The water-distribution piping is tested and must hold tight under the system's working pressure, or under a 50 psi air test for non-plastic piping, before it is concealed (IRC P2503.7).
- The framing inspection cannot proceed until the plumbing rough inspection, along with the mechanical and electrical rough inspections, has been approved (IRC R109.1.4).
- At the final drainage test, each fixture is filled and then drained, and its traps and fixture connections must prove watertight by visual inspection (IRC P2503.5.2).
- Final inspection is made after all work required by the permit is complete, and includes confirming backflow protection, such as vacuum breakers on hose bibbs, is installed (IRC R109.1.6, P2902.4.3).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Corpus Christi permit portal or by phone at 361-826-3240.

- Where do you apply for a plumbing permit in Corpus Christi?
- You can apply through the Corpus Christi permit portal or contact the City of Corpus Christi Development Services Department, Building Division directly. The links are listed on this page.
- Can a homeowner pull a plumbing permit themselves in Corpus Christi?
- Under Texas law (Tex. Occupations Code 1305.003(a)(6), 1301.051; Tex. Local Government Code 233.157(c)): Texas licenses individual construction trades rather than general contractors, so no state statute requires a license to act as your own general contractor on your own house. For electrical work, the state licensing law does not apply to work performed in or on a dwelling by a person who owns and resides in it, but only where no municipal ordinance specifically regulates that work, so city electrical licensing and permit rules still control inside city limits (Occupations Code 1305.003(a)(6)). For plumbing, a property owner does not need a state license to perform plumbing in the owner's homestead (Occupations Code 1301.051). In opt-in counties' unincorporated areas, an individual who builds their own house or acts as their own contractor is exempt from the Class C misdemeanor penalty for inspection notice failures if they intend to use the home as their primary residence (Local Government Code 233.157(c)). None of these exemptions waive local permit or inspection requirements where they apply. Confirm how Corpus Christi applies this before you apply.
