TL;DR
Arizona treats slab lift as licensed contracting, not a handyman side gig. Form an entity, open tax accounts, then apply to the Registrar of Contractors in the concrete class that fits your work. Paid jobs of $1,000 or more usually need that license. File TPT and post a bond. Confirm every fee with the board. The state does not set prices.
Do you need a license for slab lift in Arizona?
Yes. Take money to raise or stabilize a slab in Arizona and you are contracting, which means you need a Registrar of Contractors license for any real job. Statute makes unlicensed contracting unlawful. A small-job exemption exists, but only when the work is casual and the total price stays under the statutory cap.
Arizona statute sets that small-project exemption at less than one thousand dollars. [2]
A.R.S. 32-1121 describes exempt work as an undertaking for which "the aggregate contract price, including labor, materials and all other items, is less than one thousand dollars." That same section says the break dies the moment a larger job is carved into small contracts to dodge the chapter. [2]
A.R.S. 32-1151 is blunter. It is unlawful "to engage in the business, act or offer to act in the capacity of or purport to have the capacity of a contractor without having the license required by this chapter." [3]
Slab lift on driveways, patios, pool decks, garage floors, and warehouse aisles is improvement of a structure. A.R.S. 32-1101 is the definition section for "contractor." Read the current text. Do not trust a group chat. [1]
The $1,000 figure is not a business model. Material plus a morning of labor on a two-car driveway is already over it. I would not put a magnet on a truck, run ads, or bid an HOA without the license in hand. ROC finds people through advertising and complaints.
Working as a W-2 employee of a licensed shop is a different story. You can learn the gun that way. You cannot invoice the homeowner yourself.
For the license-only walkthrough, use slab lift license in Arizona. This page is the full start path, tax and first-year operations included.
Which Arizona license class covers slab lift?
Slab lift is concrete repair. On the commercial list, Arizona's C-9 Concrete class matches install and repair of concrete and the accessories that ride with it. Confirm that wording on the current ROC classifications page, because class names get edited. [8]
Residential house slabs and driveways need a residential or dual license. A commercial-only ticket will not cover a kitchen floor in Chandler. People miss this and then wonder why a complaint sticks.
I would apply for the narrow concrete class that matches the work I actually sell. A full general residential B license can include concrete as part of house work, but the exam and experience net is wider. That is extra pain if all you do is inject foam.
Polyurethane versus mudjacking does not change the license family. You are repairing a slab either way. The chemical is not a separate Arizona contractor class.
Confirm the exact class code with ROC before you pay for an exam seat. I am not the board, and this is not an approval.
How much does it cost to start slab lift in Arizona?
Nobody publishes an honest statewide startup total for this trade. Costs stack in pieces, and several of those pieces are board fees that move. Confirm every dollar with ROC, the Corporation Commission, and your insurer.
You will pay some mix of entity filing with the Arizona Corporation Commission, an IRS EIN (that filing is free), a TPT license with the Department of Revenue, ROC application and exam fees, a contractor bond under A.R.S. 32-1152, and workers' compensation if you hire anyone. [5][13][9][14][15]
I will not invent today's ROC fee. Sites that print a fee as if it were carved in granite are sloppy. Open the current ROC fee schedule and the surety's quote for your class.
The expensive part is not the paper. It is the rig. A working polyurethane injection setup (proportioner, hoses, power, drill, PPE, A/B chemical) is a five-figure decision, and it climbs fast if you buy new and wrap a truck. I would not finance shiny iron before the license prints. Line up three real bids, then buy used equipment a foam tech will still service.
Waste of money in year one: a downtown office, a second helper you cannot keep busy in July, and any vendor "certification" sold as if it were an Arizona license. Vendor training is useful. It is not ROC paper.
Insurance deposits and a month of chemical sitting in a hot van will surprise you. I like enough cash to cover several slow weeks of overhead before I quit other work. That is preference, not a rule. Nobody has good public data on first-year failure rates in this niche.
How much does slab lift cost in Arizona?
The state does not set slab lift prices. There is no Arizona tariff, no ROC rate sheet, and no university study I trust that publishes a Valley-wide average per square foot. Anyone handing you one "Arizona price" is selling something.
Owners pay by the job. Foam usually prices higher per square foot than slurry because the material costs more and the equipment is different. Access, slab thickness, void size, irrigation conflicts, interior finishes, and drive time move the number more than the city name does.
I price from yield and time, not from a national blog. Weigh the foam. Time the drill pattern. Add TPT. Add a desert heat factor from June through September, because deck surface temps change how fast two-part urethane reacts. Then decide if you even want the work.
When a homeowner asks this on the phone, I give a range only after I know square footage and access. A small patio is not a warehouse aisle that has settled two inches. I would rather lose a tire-kicker than mail a fake number.
For a structured bid sheet, the $149 Mix + Bid-per-Sqft Kit at /start is the one product SlabLiftPath sells for this. Run it against your real foam yield and your TPT rate. A kit does not replace a license.
How long does slab lift take in Arizona?
On a normal house job, you are on site a half day to a day. Drill, inject, watch the lift, patch the holes, blow off the dust. Closed-cell polyurethane often reaches handling strength in minutes. Slurry takes longer to set and makes a bigger mess.
I have not seen an Arizona agency time this. Treat those hours as field practice, not a code section.
Big warehouse or multi-unit work runs days. So does anything with interior finishes you cannot get dirty, or a slab sitting over live utilities you have to locate first.
Summer changes the clock. A west-facing Phoenix pool deck at 4 p.m. in July is a chemistry problem. I start those at dawn or I wait. Monsoon week is a soil problem. Do not promise a Friday party on a Thursday lift with storms in the forecast.
The license itself has no published guaranteed processing time I will repeat. Exam seats, bond issuance, and ROC review all move. Confirm status with the board. No approval promise belongs in your plan.
What paper do you file before you bid any job?
File the entity and tax accounts first, then the contractor license. Bidding while "the application is in" is how people get complaint files.
| Filing | Agency | What it does |
|---|---|---|
| Articles of organization (LLC) | Arizona Corporation Commission | Creates the company [15] |
| EIN | IRS | Tax ID, banking, payroll [13] |
| TPT license | Arizona Department of Revenue | Collect and remit privilege tax [9] |
| Contractor license | Registrar of Contractors | Legal authority to contract [3][4] |
| License bond | Surety, filed with ROC | Required by A.R.S. 32-1152 [5] |
A.R.S. 32-1122 is the application statute. It covers what the registrar can require, including examinations and proof that you are qualified. [4]
I form an LLC for this work. Sole prop is legal. I still want entity paper between my house and a cracked marble foyer. Confirm current ACC filing steps on the Commission site. I will not quote a filing fee here because those move.
Many cities now ride on the state TPT license through AZTaxes. Check the city you will work in anyway. A Phoenix rate stack is not an unincorporated county stack.
Keep a job file. Signed scope, photos before and after, foam lot numbers, an invoice that matches the contract. ROC complaints are document fights.
What exams and experience does Arizona want?
ROC wants a qualifying party. That person sits the exams and anchors the license technically. Arizona Administrative Code Title 4, Chapter 9 sets the experience and exam rules. Open the chapter. Do not use a forum post. [7]
For standard trade classes, the rules have long required years of practical or management experience in the work. Confirm the current year-count for your class inside R4-9. I will not treat a remembered number as gospel if the board edited the rule.
You will take a trade exam and a business or statutes exam. Testing runs through the state's exam vendor, not through ROC staff. Pass scores and retake waits sit on the current candidate bulletin. Confirm them there.
Experience letters should come from people who actually saw you do the work. Relatives make a weak file. If your background is "I watched videos and bought a used proportioner," you are not ready to apply. Go work for a licensed concrete or lift shop first. That year pays better than a denied application.
I would not pay a license mill that promises to get you qualified with a packet of vague affidavits. ROC can ask questions. So can a later complaint.
Out-of-state licenses do not stamp through. California paper can help you tell a story about experience. It does not replace Arizona exams. Compare the other path in how to start slab lift in California and the narrower slab lift license in California. Colorado is its own board too (how to start slab lift in Colorado).
What bond and insurance do you need in Arizona?
A.R.S. 32-1152 requires a contractor bond. Amounts depend on license type and what the statute and ROC currently list. Confirm the figure on the ROC bond instructions before you call a surety. [5]
The bond is for the public and the registrar. It is not general liability. Buy GL anyway. I would not step on a finished interior with a $1 million occurrence policy missing. Add an umbrella once you start doing commercial floors.
With employees, Arizona requires workers' compensation. A.R.S. 23-961 is the duty-to-secure statute. Sole proprietors can often exclude themselves. Confirm with the Industrial Commission and your carrier. [14]
Commercial auto on the rig. Hired or non-owned coverage if helpers use personal trucks. Inland marine on the proportioner if it rides on a trailer.
Isocyanate and silica exposures are real. A cheap GL policy with a total pollution exclusion can leave you naked after a foam spill in a house. Ask the broker that question in writing. Vendor installer stickers do not fill that hole.
Residential licenses also sit in the Residential Contractors' Recovery Fund under A.R.S. 32-1132. Assessments and claim rules are statutory. Confirm the current assessment with ROC. [12]
How does Arizona tax slab lift work?
Slab lift billed by a contractor is generally prime contracting for Transaction Privilege Tax. A.R.S. 42-5075 sets the prime contracting tax base at sixty-five percent of gross proceeds. [6]
The statute says "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]
You do not apply the rate to 100 percent of the invoice under that classification. You also do not invent your own percentage. Sixty-five is the number in the law.
City and county rates stack on the state rate. A job inside Phoenix is not taxed like a job in unincorporated Mohave County. The Department of Revenue TPT license page is where you start, then AZTaxes for filing frequency. [9]
I would hire a bookkeeper who has filed Arizona contractor TPT before. This is a place people get assessments. Do not mix retail chemical sales (if you ever sell drums) with contracting income on the same line without advice.
Keep exemption certificates if you ever work as a qualifying sub under a prime who handles the TPT. The paper trail matters more than the story.
I file on time even in a dead month. Late TPT is how a good license year turns into a collections problem.
What safety rules apply to slab lift crews?
You drill concrete. That is respirable crystalline silica. OSHA sets the respirable crystalline silica PEL for construction at 50 micrograms per cubic meter as an 8-hour TWA. [10]
29 CFR 1926.1153 is the rule. Table 1 has specified exposure control methods for many drill tasks. Follow it or do air monitoring. Arizona runs a state plan (ADOSH), and it still expects a silica plan you can show a visitor.
Two-part polyurethane uses isocyanates. OSHA's isocyanates guidance is blunt about sensitization and asthma. [11] I would not inject without the gloves and respirator your SDS names. Heat makes people sloppy. Heat is most of the Arizona year.
Call 811 before you punch a grid of holes in a slab that might hide post-tension cables or electrical. A PT slab in a newer Valley house is no place to freestyle a drill pattern. If you do not know how to locate PT, do not bid the house.
Hearing protection on the rotary hammer. Wet method or a shroud and vac on the bit. Shade and water for the crew. That last part is not in 1926.1153. It is how you keep people.
What does the first year of operations look like?
Slow, then lumpy. January through March you can work all day. June through August you work mornings and chase monsoon washouts and irrigation leaks. Some HOAs want you gone before the afternoon heat.
Your first marketing that works is still other trades. Foundation repair crews and pool remodelers send work when they trust you. Paid leads can wait until your close rate stops embarrassing you.
Write a one-page scope. What you lift. What you do not guarantee, because soils keep moving. What happens if a tile cracks. Photograph every crack with a tape in the frame. Arizona owners talk. A sloppy job in Gilbert follows you to Queen Creek.
I would not hire a second full-time tech until I have repeating weekly volume that survives July. Overtime on a helper is cheaper than a truck payment for someone I lay off.
TPT, bond renewal, and ROC renewal are calendar items. Put them in a shared reminder. Lapsed paper is a stupid way to stop working.
Steal process ideas from how to start slab lift in Alabama or how to start slab lift in Arkansas if you like checklists. Their boards are not yours.
What is a waste of money when you start?
Skip the national myth that a foam manufacturer licenses you to work in Arizona. They sell chemical. ROC licenses contractors.
Skip bidding interiors before you have interior foam control. A brown stain on white tile is a year of angry calls.
Skip buying every accessory the supplier catalog shows. You need a drill that survives hard aggregate, a proportioner you can get parts for in the Southwest, and PPE that people will actually wear. The extra wand kit can wait.
Skip promising "permanent" on soil that is still getting flood irrigation. Be honest in the contract. Nobody has clean data on 20-year foam performance under every Arizona soil. The closest you get is your own callback log.
Skip a second branded truck in month two. Earn the miles first.
How do you stay legal after the license prints?
Put the license number on ads, the truck, and the contract. ROC looks for that. Confirm the current display rule in Title 32 and AAC Title 4, Chapter 9. [7]
Renew on time. Recovery fund assessments, if they apply to your class, are not optional. [12]
If you add a partner or change the qualifying party, file the change. A license is not a hoodie you lend out. Compare how another western board handles the same idea in slab lift license in Colorado if you operate across a state line. Still apply in Arizona.
Keep SDS books in the truck. Keep the silica plan in the same binder. When ADOSH shows up, you want paper, not a story.
SlabLiftPath is an independent publisher. We are not a law firm and not a slab lift company. Confirm fees, class codes, and processing with the Registrar of Contractors and the Department of Revenue before you spend money. Use /start only after you know which license you are chasing.
Frequently asked questions
Do you need a license for slab lift in Arizona?
Yes for almost every paid job. Arizona treats slab lift as contracting. A.R.S. 32-1151 makes unlicensed contracting unlawful. A casual job under $1,000 can fall under A.R.S. 32-1121, but one driveway usually blows past that. Confirm the current statute text with ROC before you rely on the exemption.
How much does slab lift cost in Arizona?
The state does not set a price. No ROC tariff and no solid public study pins a Valley-wide average per square foot. Foam usually costs the owner more than slurry. Access, void size, interiors, heat, and travel move the number. Bid from yield and time, then add TPT. Be wary of anyone quoting one statewide figure.
How long does slab lift take in Arizona?
Most house patios, driveways, and garage slabs are a half day to a day on site. Foam handles in minutes. Slurry is slower and messier. Warehouses and interiors run longer. Summer decks and monsoon soils stretch the calendar. License processing has no time I will guarantee. Confirm application status with ROC.
Can I run slab lift as a handyman under $1,000?
Not as a real business. A.R.S. 32-1121 can exempt a casual undertaking under $1,000, and it blocks splitting a larger job to stay under the cap. One foam driveway is usually over the line. Advertising yourself as the slab lift person is holding out as a contractor. Get the ROC license if this is the trade.
Is mudjacking licensed the same as polyurethane slab lift?
Yes in the license family. Both are concrete repair. Arizona does not publish a separate contractor class for the chemical. You still pick residential, commercial, or dual based on who you serve. Confirm C-9 and the matching residential or dual concrete class on the current ROC classifications page before you sit an exam.
Do I need a Phoenix or Tucson city license too?
Many cities now ride on the state Transaction Privilege Tax license through AZTaxes, but local rules still differ. Check the city where the job sits, more than where you park the truck. Rate stacks change by city. Confirm licensing and tax with ADOR and the city, not with a Facebook group.
How long does the Arizona ROC license take?
There is no honest public guarantee. Time depends on a complete file, exam seats, bond issuance, and ROC review. Anyone selling a fixed number of days is guessing. Confirm current intake steps and status with the Registrar of Contractors. Do not bid while the application is pending.
What exam do I take for slab lift in Arizona?
A qualifying party takes a trade exam plus a business or statutes exam through the state's testing vendor. Content follows your license class, often the concrete trade if that is the class ROC assigns. Pass scores and retakes are on the current candidate bulletin. Confirm that bulletin. AAC Title 4, Chapter 9 is the rule book.
Can I just subcontract under a licensed general contractor?
You can work as an employee. If you bid, invoice, or hold yourself out, you are contracting and need your own license. Some primes will use a licensed specialty sub. Keep the paper clean. Unlicensed contracting is still unlawful even if a general "said it was fine."
Do I need workers' compensation if I work solo?
If you have employees, A.R.S. 23-961 requires you to secure workers' compensation. Sole proprietors can often exclude themselves. Confirm with the Industrial Commission and a carrier. A solo year can become a crew year fast. Do not wait until the first helper is already on a slab.
Does Arizona regulate the foam as a pesticide or special chemical?
Typical two-part polyurethane slab foam is handled as a workplace chemical, not as a contractor class of its own. Follow the SDS, OSHA isocyanate guidance, and hazard communication. I have not seen a separate Arizona applicator license just for residential slab foam. Confirm any odd product claim with the manufacturer and DEQ if someone tells you otherwise.
What if I only lift commercial warehouse floors?
You still need the correct ROC commercial class, usually the concrete classification, plus TPT and a bond. Skip the residential recovery fund path only if you truly never touch houses. The moment you take a patio on the weekend, the residential license problem comes back. Confirm class limits with ROC in writing.
Will my out-of-state contractor license transfer to Arizona?
No simple stamp-through. Experience earned elsewhere can support your qualifying-party story. You still apply in Arizona, sit Arizona exams, and post an Arizona bond. California and Colorado paper does not replace ROC. Confirm any limited reciprocity story directly with the registrar, not with a license mill.
What happens if I do slab lift unlicensed in Arizona?
A.R.S. 32-1151 makes acting as a contractor without the required license unlawful. You can face ROC action, money you cannot collect cleanly, and complaint-driven penalties. Advertising is how many files start. I would stop bidding, talk to a construction lawyer, and start the real application. Confirm current penalties in Title 32.
