How to Hire a Sewer Contractor in Missouri
Missouri has no state plumbing license. Every license a sewer contractor shows you in Kansas City, St. Louis or Springfield was issued by a city or county, and they do not honor one another automatically. This page explains how to check a local license, who permits lateral work on each side of the state, and how the St. Louis area's fee-funded lateral repair programs change the conversation.

Who licenses sewer contractors in Missouri
Missouri leaves plumbing licensure to local government, a patchwork. Kansas City licenses journeyman and master plumbers through the Permits Division of its City Planning and Development department, which keeps a public search of licensed contractors; work there also needs a city business license. St. Louis City has a Plumbers and Drainlayers Board of Examiners, and its Building Division issues the plumbing contractor license needed to pull a permit. St. Louis County's Public Works code enforcement office licenses plumbers and drainlayers, drainlaying being the sewer and water service work outside the building. There is no statewide register, so the check is a call or an online search at the issuing city or county. Missouri does not license general or utility contractors statewide either, though cities usually require a business license and a bond before right-of-way work. Request the liability certificate directly.
Permits and inspections
Who permits the work depends on which side of the state you are on. In St. Louis City the Building Division issues the plumbing permit, and replacing a lateral requires that permit and its inspections; the Metropolitan St. Louis Sewer District owns the public sewers, so confirm whether the connection needs its sign-off, and the street department handles any right-of-way opening. St. Louis County municipalities issue their own permits, often to a licensed drainlayer. In Kansas City, KC Water owns the sewers and permits come through the City Planning and Development Permits Division, with a separate right-of-way permit for street cuts; Independence and Lee's Summit run their own utilities. In Springfield, confirm with the city which office handles the lateral permit. Inspectors want the trench open and the connection exposed; for lining, most jurisdictions accept the post-installation video. Missouri One Call needs two working days' notice.
Who owns the pipe under the street
Across Missouri's big cities the owner is responsible for the whole lateral, house to main, street included. What differs is the help available. St. Louis City charges residential owners of six or fewer units a small annual fee on the tax bill, and the Street Department's lateral repair program pays to fix a break under the public right-of-way, not one on private ground. Many St. Louis County municipalities, Kirkwood and Brentwood among them, run their own fee-funded programs with their own caps; the sewer district itself does not fund lateral repairs. Kansas City's ordinance places the sewer service lateral on the owner, and a cut into recently paved street can add a resurfacing charge. Lee's Summit holds the owner responsible under the street too but offers a repair program. No statewide point-of-sale inspection exists.
What is under Missouri, and why it shapes the bid
Missouri sits on clay. Kansas City and the western counties have shrink-swell clay that moves pipe seasonally; St. Louis has loess over clay, and karst limestone lies close to the surface in the south and west, so rock allowances appear in Springfield and Joplin bids. Frost depth is roughly three feet, so laterals are moderate in depth but need shoring in soft clay. St. Louis brick neighborhoods from the 1890s through the 1930s have vitrified clay laterals, many draining to combined sewers. Kansas City's 1920s bungalows and 1950s ranches have clay and Orangeburg; PVC dominates after the mid-1970s. Street trees and old brick sewers are what a Missouri camera most often finds.

What a Missouri sewer bid must include
- The local license: a Kansas City master plumber number, a St. Louis County drainlayer license or the equivalent for the city where the house sits.
- The St. Louis City plumbing permit or the equivalent county or municipal sewer permit, plus the right-of-way permit for street work.
- Whether a St. Louis area lateral repair program applies, and how the bid coordinates with it.
- Rock allowances in the Ozark counties and clay dewatering in Kansas City, priced separately.
- The Missouri One Call ticket, the inspection schedule and a post-work camera recording to the main.
The full checklist, for any state, is on what a sewer bid should include.
Red flags in Missouri
- A contractor who says Missouri licenses plumbers statewide; it does not, so ask which city or county issued the license.
- A St. Louis County quote for lateral work under the street that ignores the municipal lateral repair program.
- A Kansas City bid with no line item for the street-cut and resurfacing charge the city can impose on a recently paved street.
- No Missouri One Call ticket.

Missouri sewer contractor questions
Does Missouri have a state plumbing license?
No. Missouri leaves plumbing and drainlayer licensing to cities and counties, so Kansas City, St. Louis City, St. Louis County and Springfield each keep their own rolls. Verify with the jurisdiction where the property sits.
What is the St. Louis lateral repair program in Missouri?
St. Louis City and many St. Louis County municipalities collect a small annual fee from residential owners and use it to repair defective laterals, usually the part under the public right-of-way, with caps and eligibility rules. Coverage varies by municipality, so call city hall before hiring a Missouri contractor.
Who owns the sewer lateral under a Kansas City, Missouri street?
The owner does. Kansas City's ordinance makes the property owner responsible for repairing and maintaining the sewer service lateral to the city main, and digging in the right-of-way needs a permit. A recently paved street can add a resurfacing charge.
Who issues a sewer permit in the St. Louis area of Missouri?
In St. Louis City the Building Division issues the plumbing permit a licensed plumbing contractor needs to replace a lateral, with inspections attached; the sewer district and street department may also sign off. In Kansas City, Missouri, the City Planning and Development Permits Division issues the permit, plus a right-of-way permit for the street.
Why do Springfield and Joplin, Missouri bids mention rock?
Southwest Missouri is karst country, with limestone near the surface and the occasional void. A trench there can hit rock at a few feet, so a Missouri bid in the Ozarks should carry a unit price for rock excavation, not a vague note about extras.
The short version for Missouri
In Missouri, geography decides everything. Camera first, then call the city or sewer district to confirm the permit path and whether a lateral repair program covers your address. Verify the license with the issuing city or county, since there is no state board. Compare bids that name the permits and the soil allowances, and keep the video for your records.

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.
