How to Hire a Sewer Contractor in Arizona
Arizona runs contractor licensing through a single registrar, which makes checking a sewer company easier than in most states. This page explains which Registrar of Contractors classifications cover a lateral, who permits the work in Phoenix, Tucson and Mesa, where city responsibility begins under the street, and why caliche matters.

Who licenses sewer contractors in Arizona
The Arizona Registrar of Contractors, known as the ROC, licenses every contractor doing work above its handyman threshold, and sewer laterals fall squarely inside that. Two classifications matter most. C-37 Plumbing covers plumbing within property lines, and its scope expressly allows the sewer run to the nearest public connection even across an easement. A-12 Sewers, Drains and Pipe Laying is the commercial classification for right-of-way work and for connecting a collector line to a building drain; the dual CR-80 version adds residential rights. A general engineering A license covers it too. The old residential-only R-37R sewer card is closed to new applicants, so a company holding only that is an older company, fine if still active. Use the ROC's Contractor Search to confirm the number on the bid is current, bonded and free of open complaints. Arizona's Residential Contractors' Recovery Fund protects homeowners failed by a licensed residential contractor.
Permits and inspections
In Phoenix, a sewer repair on private property is a plumbing permit from Planning and Development, and anything in the street or alley requires a right-of-way permit before the cut. Tucson splits duties: the city building official permits the private pipe, while Pima County Regional Wastewater Reclamation Department owns the public sewer and its connection records. Mesa handles both through Development Services. Expect an inspector to see the trench open before backfill and, for a lined pipe, a post-lining camera pass. Arizona 811 requires a locate ticket two working days before excavation, held by the contractor. The licensed contractor pulls the permit under its ROC number; a request that you apply as owner-builder usually means the firm lacks that scope.
Who owns the pipe under the street
Phoenix writes the rule into city code: the owner must clean, unstop, maintain and repair the building connection from the structure to the public sewer. For single-family homes and duplexes, though, the city itself repairs a damaged section lying in the public right-of-way. Commercial and multifamily owners fix the street portion at their own cost and need a permit first. Pima County takes the stricter line around Tucson, treating the private house connection sewer as owner property up to and including the connection to the public pipe. Mesa, Chandler and Gilbert generally follow the Phoenix model, but confirm with the utility. Arizona has no point-of-sale lateral ordinance. The utility makes the tap.
What is under Arizona, and why it shapes the bid
Two things define Arizona digging: caliche and heat. Caliche is a cemented calcium carbonate layer that can sit a foot below the surface across the Phoenix and Tucson basins, and breaking through it with a hoe ram is slow, so excavation footage costs more than the same trench in loam. Soils are otherwise alkaline sands and gravels with little groundwater, so open cuts are shallow and shoring is simpler than back east. Pipe eras run cast iron and clay in pre-1960 Phoenix neighborhoods, ABS and some Orangeburg in 1960s and 1970s tracts, and PVC since. Summer ground temperatures affect resin cure for lining. Flagstaff adds frost and volcanic rock; mesquite roots find every joint.
For the lining methods themselves, the Sewer Pipe Lining Arizona pipe lining guide goes into what fails in the ground here and which method fits.
What a Arizona sewer bid must include
- The ROC license number and classification, with C-37, A-12 or CR-80 named rather than a generic reference.
- The Phoenix or Tucson permit type, who pulls it and whether right-of-way work is included.
- Caliche excavation as a separate unit price, since it can double digging time.
- Who performs the tap at the public main and whether the county or city charges.
- Pavement, sidewalk and landscape restoration with the city's compaction and asphalt specifications.
The full checklist, for any state, is on what a sewer bid should include.
Red flags in Arizona
- No ROC license number, or one the Contractor Search shows as suspended or expired.
- A claim that Phoenix needs no permit for a lateral repair in the yard.
- No caliche or rock allowance in an Arizona bid, meaning a change order later.
- Skipping the Arizona 811 ticket on a shallow line.
Finding a sewer contractor in Arizona

Where Arizona property owners ask for help most
The rules above apply statewide; the communities below are the ones that generate the most questions.
Arizona sewer contractor questions
Which Arizona ROC license covers sewers?
C-37 Plumbing covers the lateral inside property lines and out to the nearest public connection. A-12 or the dual CR-80 covers right-of-way sewer work. Check the Arizona Registrar of Contractors search to see which the company holds.
Who fixes a Phoenix lateral in the street?
For single-family and duplex homes, Phoenix repairs the damaged section in the public right-of-way itself. Commercial and multifamily owners pay for that stretch and must pull a permit first. On private property the owner is responsible across Arizona.
Does Tucson follow the same rule?
No. Pima County Regional Wastewater Reclamation treats the private house connection sewer as the owner's responsibility all the way to the public pipe, including the connection. Arizona has no statewide rule, so the utility decides.
Why do Arizona bids add excavation fees?
Caliche. This cemented soil layer sits shallow across the Phoenix and Tucson basins and must be broken mechanically, which slows trenching. A bid without a caliche line item is a bid that will grow once digging starts.
Is there a recovery fund in Arizona?
Yes. The Residential Contractors' Recovery Fund, administered by the Arizona Registrar of Contractors, can compensate homeowners harmed by a licensed residential contractor. Hiring an unlicensed company forfeits that protection, which is one more reason to check.
The short version for Arizona
Order of operations in Arizona: camera inspection first, with a recording you keep. Confirm the ROC license number and classification on the Contractor Search, then ask the city or county which permit applies and who pulls it. Compare bids on caliche, restoration and the tap, not footage. Insist on the open-trench inspection and a final video before paying the balance.

How a job runs
Camera first. Always.
A sewer quote given without video is a guess, and guesses are how homeowners end up paying for a liner that was never going to fix the problem. Here's the sequence we follow on every job.
-
Step 1
Describe the symptom, then stop talking price
Backups, gurgling, a wet patch in the yard, or a sewer-scope report from a home inspection. A contractor who names a number at this point is guessing, and a guess is what you will be paying for.
-
Step 2
Camera through the full line, recorded
From the cleanout to the main, with distances on screen and each defect located from above with its depth. You keep the recording. No price exists until this is done.
-
Step 3
License, insurance and permit, checked by you
Look the license number up on the state or local register named in your state's guide. Ask for the insurance certificate. Ask who pulls the permit and which inspections follow; your state page says what the answer should be.
-
Step 4
A written scope that names the alternatives
Footage, diameter, method, access points, reinstated connections, restoration, warranty, and a sentence on why the other methods were set aside. Two or three of these are what you compare, not two or three phone quotes.
-
Step 5
The work, with the inspections on the calendar
A lined lateral is usually a day; a burst lateral one to two; an open cut depends on depth and surface. The utility inspection and the post-work video are scheduled before the crew arrives, not remembered afterward.
-
Step 6
Final video, warranty and permit sign-off in your file
The camera goes back through the finished pipe while you watch. That recording, the written warranty and the closed permit are what the next buyer's inspector will ask for.
