Chandler plumbing inspections: the required list and inspection codes

The Homeowner Building Permit Manual lists the minimum inspections and says the "building inspector must approve all work before construction can proceed to the next level. All work to be inspected must be accessible and exposed." The plumbing-related stages are:

The manual adds that rough electrical, plumbing and heating and ventilation inspections are typically done concurrently, and that the framing inspection happens with plumbing, mechanical and electrical rough-ins in place but not covered. It also says to consult your building inspector for all inspections specific to your project.

• Groundwork (underground): pipe below the slab or in the ground, inspected before it is covered.
• Rough-in (topout): pipe inside walls and ceilings, inspected under pressure test before drywall.
• Shaded: bedded in sand or fine fill, as the manual describes for building drain and sewer pipe.
• Correction notice: what the inspector issues when the work does not pass.

The city's inspections page lists these plumbing and gas codes:

The same list also carries 737 (Haz Mat Gas Systems), 738 (Secondary Cont Piping), 739 (Process Piping), 740 (Roof Drains), 743 (Plumbing Special) and 744 (Plumbing Other). The inspection card issued with your permit lists the codes that apply to your job.

It covers any work done under a Chandler plumbing or building permit, whether a homeowner pulls the permit for their own home or a licensed contractor does. The manual is written for homeowners, but the city's inspection codes are the same ones contractors use. Exempt work, such as a like-for-like water heater swap, has no permit and so no permit inspections. When a changeout does need a permit (an upsize, a relocation or new piping), inspection code 742, Water Heater Changeout, is the one you book.

A bathroom addition. The plumber runs the drain and vent in the wall, pressure tests the rough plumbing, and books code 733 before drywall goes up. The inspector passes it, the wall is closed, and the final inspection (745) happens after the fixtures are set.

A slab job. The under-slab building drain is installed, shaded with bedding and under a pressure test. The plumber books the groundwork inspection before the concrete crew arrives. If the pipe is covered first, the inspector cannot approve what they cannot see.

The edge case: a water service or meter change. Code 745 is named "Plumbing Final and Water Meter Verified," so the final inspection includes the city's meter verification. Ask the inspector what they need at the meter when you book it.

1. 1Have your permit number and the three-digit inspection code from your inspection card.
2. 2Book at least one business day ahead, as the manual instructs.
3. 3Use any of the city's channels: the CLICS portal (chandleraz.gov/clics), the automated phone line at 480-782-3100, or text to 844-281-3520 in the format "s permit-number inspection-code date."
4. 4Make sure the work is exposed and under test when the inspector arrives.
5. 5Check the result online, by phone or by text. The inspector either approves the work or issues a correction notice.

• "I can cover it and call later." The manual requires work to be accessible and exposed for inspection.
• "One rough-in inspection covers everything." Underground stages, upper-level drainage and water service each have their own request point.
• "Any code works." Use the code that matches the work, such as 731 for the building drain and 745 for the plumbing final.
• "The pressure test is the plumber's business." The manual says several stages are inspected under pressure test, so the test must be ready when the inspector shows up.

Chandler can revise its inspection procedures. This page reflects the manual revised April 9, 2026 and the city's inspection page as checked on the date above.
