TL;DR
Paid slab lift in Arizona is contractor work. Bid, advertise, or take jobs over the small-project line in A.R.S. 32-1121 (written as $1,000 including labor and materials when last checked) and you need a Registrar of Contractors license that covers concrete repair. Confirm the class, bond, exam, and experience with ROC. Add TPT, 811 locates, and insurance before you drill.
Do you need a license for slab lift in Arizona?
Yes. Paid slab lift on someone else's property is contractor work in Arizona. You need a Registrar of Contractors license unless you fit a current A.R.S. 32-1121 exemption. The small-project line is still written as a completed contract under $1,000 including labor and materials. True owner-builder work on a place you will occupy is a different exemption. Advertising a slab lift business is no exemption at all. [1][3]
A.R.S. 32-1101 pulls repair of a structure or improvement into the contractor definition. A sunken driveway, patio, pool deck, or warehouse slab is an improvement. Foam or slurry under that slab is repair. [2]
A.R.S. 32-1151 is blunt. "It is unlawful for any person, firm, partnership, corporation, association or other organization, or a combination of any of them, to engage in the business of, submit a bid or respond to a request for qualification or a request for proposals for construction services as, act or offer to act in the capacity of or purport to have the capacity of a contractor without having the contractor's license" in good standing for that work (A.R.S. 32-1151). [1]
Read that again if you planned to stay under $1,000 per invoice while running ads. Stacking invoices on one project to dodge the cap is how people collect complaints. The statute talks about the project, not creative billing.
I would not start a slab lift route in Arizona on the exemption. The exemption is for a neighbor's tiny step. It is not a company.
Unlicensed work also hurts you when a customer refuses to pay. Courts are not eager to enforce an illegal contract. Licensed residential contractors sit under the recovery fund in A.R.S. 32-1132. Unlicensed operators get no such shield, and customers know how to search it. [5]
Confirm the live text of 32-1121 before you price anything you want to call exempt. The legislature has rewritten Chapter 10 more than once. I am not going to pretend a dollar line is immortal.
Which board actually licenses slab lift in Arizona?
The Arizona Registrar of Contractors is the board that licenses slab lift contractors. Not the Corporation Commission. Not a city cashier. ROC lives in A.R.S. Title 32, Chapter 10 and in Arizona Administrative Code Title 4, Chapter 9. [2][8]
ACC only files the company. ADOR only taxes the receipts. Cities only sell local privilege licenses. None of those let you bid concrete repair.
ROC issues the license, sets classification scopes, runs the qualifier exams, holds bonds, hears complaints, and administers the residential contractors' recovery fund. [5][8][9]
Arizona runs no standalone foundation board and no slab lift board. People search those words because that is how the work feels. The counter you actually use is ROC.
Hold paper in another state and you still apply here. Look at California if you work both sides of the Colorado River. CSLB is a different statute stack. Colorado mixes state and local rules in a way Arizona mostly does not.
I would bookmark the ROC classification list and the AAC Title 4, Chapter 9 PDF. Ignore random license coaches.
What license classification covers slab lift in Arizona?
Open the current ROC classification list and match the scope that lets you form, pour, finish, and repair concrete. Slab lift is repair. Confirm the live class code with the registrar before you pay an exam fee. I am not printing a letter-number here because ROC has regrouped trades, and a wrong class stalls the file. [8]
Polyurethane injection and old-school mudjacking both land as concrete repair. The pump does not create a chemistry license. If you also saw-cut and replace panels, read the concrete cutting scopes so you do not wander out of class.
I would not buy a full general residential building license just to lift driveways and patios. That path is longer. It wastes money if you will not build houses.
Decide residential, commercial, or dual based on year-one bids, not a fantasy warehouse account. Dual costs more and covers more. Residential-only is fine for houses and many HOA pads. It blocks you when a strip-center landlord calls.
One qualifying party takes the exams and hangs their experience on the license. That person can be you or a responsible managing employee. Do not rent a qualifier you cannot reach on a Tuesday. When they resign, your ability to contract gets sick fast. Read A.R.S. 32-1122 for how the registrar treats qualifications. [4]
If your other work is dirt or waterproofing, do not assume those classes cover foam. Ask ROC in writing. Save the email.
Neighbors in Idaho and Illinois use different class names for the same drill pattern. Do not copy their checklists onto an Arizona form.
How much does slab lift cost in Arizona?
Nobody in Arizona government publishes a consumer price for slab lift. ROC does not set rates. There is no official statewide average. Be suspicious of anyone who gives you one number and a straight face.
Bids in Phoenix, Mesa, Chandler, Tucson, and Flagstaff usually show a per-square-foot price. The real driver is volume of foam or slurry, access, drill count, and how far the slab has dropped. A 400 sq ft patio with a 3/4 inch dish is not the same job as 400 sq ft of garage with a washed-out corner.
National contractor practice for polyurethane often lands in the mid single digits to the low twenties per square foot of treated area. Arizona sits in that same band on ordinary work. I have no peer-reviewed Arizona price study to cite. The closest honest statement is that volume and access beat ZIP code.
Mudjacking usually comes in cheaper per foot and heavier. It is a mess next to a pool. I would not use it inside a finished store if the client cares about dust.
Heat is a cost. Crews slow down after 3 p.m. in July. Water, shade, and earlier starts are not optional. Monsoon washouts create rush calls. Rush is no reason to skip 811.
First-year operators underprice mobilization and the second visit. I would add TPT, mileage, and a callback reserve, then stop cloning old Facebook quotes.
Want a bid sheet already split mix and per-square-foot? SlabLiftPath has a $149 Mix + Bid-per-Sqft Kit. A notebook works too.
Homeowners should get two or three licensed bids. Ask what square foot means. Ask if they checked for post-tension cables. The lowest number that ignores tendons is not the deal.
How long does slab lift take in Arizona?
Most residential polyurethane slab lift jobs in Arizona are same-day work. A simple driveway or patio is often a few hours once you are allowed to drill. Foam reacts in minutes. No Arizona statute sets a cure clock for residential lifts.
Mudjacking can need more wait before a truck parks on it. Put that wait in the contract so you do not argue in the driveway.
Commercial floors, grocery nights, and occupied offices run longer than the injection. Dust walls and reopen rules eat the clock.
Call 811 and wait two working days before you excavate. A.R.S. 40-360.22 requires two working days' notice to the one-call center before excavation begins. [7] Skip locates to save a day and you hit a gas line.
Valley monsoon months can kill an afternoon. Heat alone does not stop poly. Standing water in the holes does.
I tell homeowners the honest window is one work day on a simple pad, plus locate wait, plus any city permit if the city even wants one. Multi-slab HOA streets take multiple days. Nobody has good public data on average Arizona cycle time. Your schedule is the crew and the locate ticket.
Pavement-preservation practice at the federal level treats polyurethane slab jacking as a rapid-reopen method on roads. That is DOT work, not your patio, but it matches what you see in the field. [14]
What paper does the Registrar of Contractors want first year?
Confirm current forms, fees, exam vendors, and bond amounts on the ROC pages. I will not invent a processing time or a fee. Those move. [8][9]
The first-year stack looks like this in plain language.
| Item | Who issues it | Confirm where |
|---|---|---|
| ROC contractor license | Registrar of Contractors | A.R.S. Title 32, Chapter 10 and AAC Title 4, Chapter 9 |
| Qualifier exams and experience | ROC | A.R.S. 32-1122 and the live class list |
| TPT license | ADOR | A.R.S. 42-5005 and 42-5075 |
| LLC articles | Corporation Commission | A.R.S. 29-3201 |
| 811 ticket before drilling | Arizona 811 | A.R.S. 40-360.22 |
You also need a license bond in the amount on the current ROC table, plus recovery fund compliance for residential work, plus whatever background questions the form actually asks. [4][5][8]
A.R.S. 32-1122 is the qualifications statute. Read the live text. Do not let a Facebook group paraphrase it. [4]
Experience letters should name dates, duties, and who will still pick up the phone. Vague I-helped-my-uncle packages get questioned. Short on years? Say so and ask ROC about acceptable combinations. Do not invent months.
Bond through a surety that already writes Arizona contractor bonds. Cheap online bonds that fail underwriting after you scheduled the exam waste your money and your time.
I would keep the application PDF, bond rider, exam confirmation, and TPT license in one folder. When a GC asks for your paper, you send that folder the same day.
Do you pay Arizona transaction privilege tax on slab lift?
Yes. Treat paid slab lift as prime contracting unless ADOR gives you written facts that say otherwise. Arizona does not let contractors pretend they only sell foam as a retail product.
A.R.S. 42-5075 is the prime contracting classification. Arizona Revised Statutes 42-5075 sets the prime contracting tax base at sixty-five percent of gross proceeds. [6]
The statute's own words: "The tax base for the prime contracting classification is sixty-five percent of the gross proceeds of sales or gross income derived from the business." [6]
That is the number. You do not invent a different deduction on a napkin.
Pull a TPT license on the joint tax application before you invoice. A.R.S. 42-5005 is the privilege license statute. Most cities still want their own privilege license too. Phoenix is not Tucson. Flagstaff is not Mesa. [10]
I would put TPT in every bid from week one. Discounting the tax to win a Nextdoor job is how the first summer ends early.
Work public jobs and you should ask about additional withholding rules. Do not guess.
Do you need a building permit to lift a driveway or slab?
Often no permit for a straightforward driveway, patio, or private sidewalk lift. Sometimes yes if you touch a house foundation, a pool structure, or a public walk.
Arizona cities do not share one building desk. Call the address jurisdiction with a one-line scope. Write down who you spoke with. I would not drill a residence on a forum answer.
HOA approval is separate. An HOA can restrict staging even when the city does not care. That fight is contractual.
Public sidewalks and alley aprons often belong to the city. Lifting those without a right-of-way permit is a good way to meet an inspector. I would walk those jobs unless the paper is in the truck.
Maricopa County islands and Pima County islands confuse new operators. The city limit is not always the curb you are looking at. Check the parcel.
Do you have to call 811 before you drill in Arizona?
Yes, treat slab drilling into soil as excavation and call Arizona 811. A.R.S. 40-360.22 requires two working days' notice to the one-call center before excavation begins. [7]
White-paint the work area. Wait for marks. If a high-pressure gas line crosses your grid, you redesign or you decline.
811 does not mark post-tension cables. Those live in the concrete. Separate problem, separate tool.
I have watched people just drill the edge on a gas easement. Do not be that story. The two-day wait is cheaper than the hole you cannot undo.
Private water lines from the meter to the house may not show. Talk to the owner. Probe. Stay humble.
How do Arizona soils and post-tension slabs change the job?
Valley houses from the 1980s onward often sit on post-tensioned slabs. You do not grid-drill those like a 1964 plain slab. Cut a tendon and you buy an engineer and a year you will not enjoy.
Ask for drawings. Use a cover meter. If there are no drawings, say that in the contract and drill only where the owner authorizes after you explain the risk.
Caliche can block foam travel. Expansive clay pockets still exist in parts of the Valley and will move with water. A June lift can look proud in February if clay and irrigation are the real problem. I write tolerance, not forever level.
Monsoon scuppers and backyard splash pads dump water under garage corners. Skip the drainage talk and you get a callback. Charge for that conversation or leave the job on the table.
Florida and Georgia fight organic soils and humidity. Arizona fights mineral layers, irrigation, and PT cables. Do not import a Gulf Coast drill map.
Interior lifts in winter rentals still happen in Flagstaff and Prescott. Freeze-thaw is a northern-Arizona problem people from Phoenix forget.
What insurance and bond should you carry the first year?
Buy the ROC bond in the amount on the current class table. Confirm it. Do not reuse a number you heard in 2018. [8][9]
I would not step onto a customer's slab without general liability. Many commercial GCs start the conversation at $1 million per occurrence. Ask a broker who already writes Arizona contractors. I am not your broker.
Workers' compensation applies when you have employees. A.R.S. 23-902 is the employers statute inside Arizona's workers' compensation scheme, and the Industrial Commission is the agency. A sole proprietor exclusion does not turn a regular helper into a ghost. Misclassifying labor is a first-year fire. [11]
Drill or grind concrete and OSHA's respirable crystalline silica standard applies. 29 CFR 1926.1153 sets a 50 µg/m³ PEL. [12] A cheap gas-station dust mask is not a program.
Auto coverage for crew trucks. Inland marine if you own a proportioner. Waste of money: mystery foundation specialty policies you cannot explain, and bonding through a Facebook middleman who never posts a surety name.
Should you form an LLC before you apply at ROC?
If you are building a real company, file an LLC with the Arizona Corporation Commission before you put a name on the ROC application. Formation is a short articles filing under A.R.S. 29-3201. Confirm the live fee on the Commission filing table. I will not print a fee that can move. [13]
The LLC does not replace the ROC license. It does not replace TPT. It does not hide the qualifying party from complaints.
Get an EIN. Open a bank account that is not your rent account. Names should match on ROC, ADOR, the bond, and the invoices.
Out-of-state companies register as foreign. A license from Alabama or Arkansas does not transfer. Arizona wants its own qualifier path.
I would not sit in a professional association that is really a lead mill before I had the license number. That wastes money.
What would I actually do if I were starting in Arizona?
I would read A.R.S. 32-1101, 32-1121, 32-1122, and 32-1151 myself. [1][2][3][4] Then I would call ROC and ask which live concrete classification covers polyurethane and cementitious slab lift. I would write down the person's name.
I would file the LLC, apply for TPT, collect GL quotes, and start the qualifier books. I would not buy a full foam rig until I had licensed work I could actually perform. Rent or partner the first jobs.
I would learn post-tension layouts before I ran ads that say any slab. I would open an Arizona 811 account and actually use it. [7]
I would skip paid outfits that promise a license on a clock. Nobody honest can guarantee ROC timing.
Keep the first contracts boring. Driveways and patios with access. HOA pool decks with drawings. Leave structural house leveling until you have an engineer relationship.
SlabLiftPath is an independent publisher, not a law firm and not a service company. Want the bid kit after the license plan is real? It is at /start. Confirm every fee and form with ROC, ADOR, ACC, and the city that takes your tax.
Frequently asked questions
Do you need a license for slab lift in Arizona?
Yes for paid work on someone else's property. Arizona treats slab lift as contractor repair. You need an ROC license unless you fit A.R.S. 32-1121, including the small-project line written as under $1,000 including labor and materials, or a true owner-builder job. Running ads as a slab lift company is not a plan. Confirm the live statute before you invoice.
How much does slab lift cost in Arizona?
No Arizona agency publishes a consumer price. Bids usually look like a per-square-foot number but track foam or slurry volume, drop depth, and access. National polyurethane practice often lands from the mid single digits to the low twenties per treated square foot. Arizona ordinary work sits in that band. Get two or three licensed bids and ask how they measure area.
How long does slab lift take in Arizona?
Most residential polyurethane lifts are same-day, often a few hours on site after you can drill. Foam reacts in minutes. Mudjacking can need a longer wait before parking. Add two working days for an 811 ticket under A.R.S. 40-360.22, plus any city permit if one applies. Multi-slab commercial or HOA work runs longer.
Which Arizona license classification is slab lifting?
Use the live ROC concrete classification whose scope allows forming, pouring, finishing, and repairing concrete. Slab lift is repair. Confirm the current class code with the registrar. I would not print a letter-number that ROC may have regrouped. Do not buy a full general building license just to lift driveways.
Can I stay under the $1,000 exemption and run a slab lift business?
No. A.R.S. 32-1121's small-project line is written as under $1,000 including labor and materials for a project, not as a business model. A.R.S. 32-1151 also bars bidding and holding yourself out as a contractor without a license. Confirm the live exemption text. I would get licensed if I planned to advertise.
Does Arizona charge transaction privilege tax on slab lift?
Treat it as prime contracting unless ADOR tells you otherwise in writing. A.R.S. 42-5075 sets the tax base at sixty-five percent of gross proceeds. You also need a TPT privilege license under A.R.S. 42-5005, and most cities want their own privilege license. Price the tax into the bid. Do not eat it to look cheaper.
Do I need to call 811 before I drill a slab?
Yes if you are excavating into soil under the slab. A.R.S. 40-360.22 requires two working days' notice to the one-call center before excavation begins. Arizona 811 is that center. The ticket will not mark post-tension cables inside the concrete. Those need drawings or a cover meter, not 811 paint.
Are post-tension slabs a real issue in Arizona?
Yes, especially on Valley houses built from the 1980s forward. A tendon hit is an engineer-and-repair event, not a patch. Ask for as-builts, scan the slab, and write the unknown into the contract if drawings are missing. Do not market a grid-drill pattern as if every Arizona house is a 1960s plain slab.
Do I need a building permit to lift a driveway?
Often no for a private driveway or patio. Sometimes yes for house foundations, pool structures, or public sidewalks. Cities and counties do not share one rule. Call the building desk for that address with a one-line scope. HOA approval is separate and can still block staging when the city does not care.
What happens if I lift slabs without an ROC license?
A.R.S. 32-1151 makes unlicensed contracting unlawful, including bidding and holding out as a contractor. You can face ROC action and you can lose the ability to collect in court. Customers on residential jobs also look to the licensed recovery fund under A.R.S. 32-1132, which you will not have if you stayed unlicensed.
Do I need workers' compensation as a solo operator?
If you have employees, Arizona workers' compensation applies and A.R.S. 23-902 is the employers statute to read. A sole proprietor can sometimes exclude themselves. That exclusion does not turn a regular helper into a non-employee. Misclassifying labor is a common first-year fire. Ask the Industrial Commission or a broker, not a forum.
Can I use my out-of-state contractor license in Arizona?
No. Arizona wants its own ROC license and a qualifier who meets A.R.S. 32-1122 and the live class rules. An LLC from another state still files as a foreign entity at the Corporation Commission. There is no handshake reciprocity that lets you bid slab lift on a California or Alabama card alone.
Is mudjacking treated differently from foam lifting by ROC?
Both are concrete repair if you are lifting and supporting an existing slab. The material does not create a separate chemistry board. Confirm your class scope still covers the method you actually pump. If you also cut and replace panels, read adjacent concrete-cutting scopes so you stay inside the license.
Where do I confirm current ROC fees and bond amounts?
On the Registrar of Contractors fee and classification materials, plus Arizona Administrative Code Title 4, Chapter 9. I will not print a fee or a processing time. Those change. Read A.R.S. 32-1122 for qualifications, then pay what the live ROC table says for your class and bond.
