Phoenix's online permits flyer lists three commercial plumbing jobs a licensed contractor can permit online: Replace Water Heater, Minor Plumbing Repipe and Gas Pipe Repair. The work must be minor enough to skip plan review. New permit applications now go through the SHAPE PHX portal.
“The following permits can be obtained by applicants with licensed contractors for minor electrical, plumbing, and mechanical work at commercial properties.”
- Applies to:
- Licensed plumbing contractors and the owners, tenants and property managers of commercial buildings in the City of Phoenix
- Official fee:
- Table A valuation-based fee; the $98 water heater minimum is written for residential water heaters (PDD Fee Schedule, Ord. G-7465, effective 2026-01-20)
- In force:
- 2024 Phoenix Building Construction Code (Ord. G-7397); flyer undated, since August 1, 2025
- Last verified:
- September 28, 2026, against the official page
A dead water heater in a restaurant does not wait for plan review. Phoenix built a fast lane for that kind of small commercial job: a licensed contractor buys the permit online, and a city inspector checks the work afterward. The catch is that the fast lane is narrow, and the city's own list of eligible jobs is a flyer that has not kept pace with the new permit portal.
What does the city's flyer say?
The Online Permits flyer (TRT 00933) says "The following permits can be obtained by applicants with licensed contractors for minor electrical, plumbing, and mechanical work at commercial properties." It adds that "the contractor must verify in advance the building's electrical and plumbing systems can handle the change." The plumbing-related entries on its commercial list are:
- Replace Water Heater
- Minor Plumbing Repipe
- Gas Pipe Repair
The flyer says these permits cover minor work "that does not need plan review," that "code compliance will be verified by a city inspector," and that you can "purchase a permit and schedule an inspection online when work is complete." It is undated and predates the new portal. Phoenix's PDD Online page now says new applications go through the SHAPE PHX Portal after the April 27 release, and it links "Quick Commercial Permits" for triplexes, fourplexes, apartments, condominiums and commercial properties.
What do the key terms mean?
- Minor: the flyer does not define it. Read it as work small enough that the city does not need drawings, which is the flyer's own "does not need plan review" test.
- Licensed contractor: Phoenix's administrative provisions require permitted plumbing work to be done by a licensed journeyman or apprentice, with an exception for a person licensed as a contractor by the State of Arizona (Section 119.1).
- Annual Facilities Program (AFP): a Phoenix registration program for large facility owners. AFP properties "should work with their assigned inspector or call 602-262-7501" to get permits.
Who does this cover?
Licensed contractors doing small jobs at commercial properties. It does not cover properties in designated historic districts or any property with unresolved non-permitted construction cases, which the flyer says are not eligible. It does not cover work that needs plan review. And the water heater exemption that lets a homeowner's contractor skip the permit applies only to one- and two-family dwellings (Section 105.2 Plumbing item 5), so a commercial water heater swap needs a permit.
Quick check: which route does my commercial job take?
| Job | Route | Why |
|---|---|---|
| Replace a commercial water heater | Online permit by a licensed contractor | Flyer lists it, and the code's water heater exemption is for houses |
| Small repipe, no relocation of fixtures | Online "Minor Plumbing Repipe" permit | Flyer lists it |
| Repair a gas pipe | Online "Gas Pipe Repair" permit | Flyer lists it |
| Clear a stoppage or fix a leak with no pipe replaced | No permit | Section 105.2 Plumbing item 2 |
| Repair or replace a 2-inch or smaller secondary backflow assembly | No permit, with a certified tester's report | Section 105.2 Plumbing item 6 |
| Add or move fixtures, or a full build-out | Commercial plan review | Not minor work |
| Property in the Annual Facilities Program | Work through the assigned inspector | Flyer |
| Historic district or open unpermitted-work case | Not eligible for online permits | Flyer |
What does this look like in real life?
- Friday night water heater failure at a restaurant. The replacement heater goes in over the weekend. Phoenix's code says equipment replacing existing equipment that serves an occupied part of a building may operate if an inspection request is filed within 72 hours after the work is finished and before anything is concealed. The contractor pulls the online permit and files the request inside that window.
- Office building repiping one restroom group with no fixture moves. This matches the flyer's Minor Plumbing Repipe entry. If the job reroutes or adds fixtures, it is no longer minor.
- Retail suite in a historic district. The same water heater swap cannot use the online lane. It goes through the regular commercial channel.
- A property with an open unpermitted-work case. The online permit is closed to it until that case is resolved, which flips the answer for an otherwise routine repair.
What should you do next?
- 1Hire a plumbing contractor licensed in Arizona. Phoenix's permit lane is for licensed contractors, not owners.
- 2Have the contractor confirm the building can handle the change: gas capacity for a new heater, electrical capacity for an electric one, water pressure and pipe condition for a repipe.
- 3Rule out the exclusions: historic district, open unpermitted-work case, or Annual Facilities Program registration (602-262-7501).
- 4Set up a business account in SHAPE PHX (questions go to shapephx@phoenix.gov) and choose Quick Commercial Permits. Because the flyer predates the portal, call PDD at 602-262-7811 to confirm the current list of quick permit types before you buy.
- 5Buy the permit, finish the work, and schedule the inspection in the portal. For replacement equipment serving an occupied space, request the inspection within 72 hours.
What do people get wrong?
- "A commercial water heater swap is exempt like a house." The exemption is written for one- and two-family homes and a licensed contractor.
- "Online means no inspection." The flyer says a city inspector still verifies compliance.
- "Any repipe qualifies." Only minor work that needs no plan review does.
What happens if you skip the permit?
The PDD Fee Schedule lists an investigation fee of "$250 or the permit fee, whichever is greater, but not to exceed $2,500 for every day or portion of a day from the time unpermitted work began until a permit is obtained."
