Do You Need a License or Permit for a Bathroom Remodel in Knoxville?
Usually both. Knox County requires a state license for contractor jobs of $3,000 and up. Knoxville and Knox County require permits when you replace or move fixtures, pipes, valves or circuits. Tile, paint, cabinets and countertops alone usually need none.
This guide is general information, not legal advice. Rules change, so confirm with your permit office. Last reviewed October 2026.

What License Does a Knoxville Bathroom Contractor Need?
It depends on the total price. Count materials and labor together.
| Project total | License needed | Notes |
|---|---|---|
| Under $3,000 | No Home Improvement license | Plumbing and electrical still follow trade rules |
| $3,000 to $24,999 | Home Improvement license | Knox County has adopted this law |
| $25,000 and up | Tennessee contractor license | Needed before the contractor bids or quotes a price |
Sources: County information on the Home Improvement law and the Tennessee Board for Licensing Contractors. A license is required whether or not a permit is needed.
What Does a Home Improvement License Require?
- $10,000 in financial responsibility. A surety bond, cash bond, property bond or letter of credit.
- $100,000 in liability insurance plus workers’ comp for employees.
- $250 for a two-year license. No exam.
- A written contract. Licensed contractors must put the job in writing.
Do Plumbing and Electrical Need Their Own License?
Yes. The Home Improvement license does not cover plumbing, electrical or HVAC.
| Trade | What the rule says |
|---|---|
| Plumbing | Jobs under $25,000 need a Limited Licensed Plumber, unless the contractor holds a CMC or CMC-A plumbing license. Nobody may split a job to stay under the limit. |
| Electrical | The state Limited Licensed Electrician license applies only where the local office has no licensing of its own. Ask the city or county. |

How Do You Check a Contractor License?
Lookup: verify.tn.gov.
What Happens If a Contractor Has No License?
- No lien rights. An unlicensed contractor cannot file a lien for the work.
- Limited pay. In court, an unlicensed contractor may recover only documented expenses, not the full price.
- Criminal exposure. Contracting without a required license is a Class A misdemeanor under T.C.A. 62-6-120.
- You carry the risk. A contractor working under your homeowner permit can leave you open to injury, nonpayment and lien problems.

Which Bathroom Jobs Need a Permit?
| Job | Permit? |
|---|---|
| Paint, tile, cabinets, countertops | Usually no |
| Fixing a leak or clearing a clog | No |
| Taking out and reinstalling a toilet with no new pipes, valves or fixtures | No |
| Replacing a toilet, vanity or tub with new fixtures or valves | Likely yes. Ask your office first |
| Moving a drain, shower or sink | Yes, a plumbing permit |
| Replacing a hidden bad drain or vent | Yes, it counts as new work |
| Adding or moving circuits for lights, outlets or heated floors | Yes, an electrical permit |
| Changing the layout or framing | Yes, a building permit |
Based on the City of Knoxville residential permit guide and its 2018 IRC exemptions. Farragut and Knox County set their own rules.
Which Permits Does a Typical Remodel Pull?
- Residential Alteration or Repair. The building permit for layout or finish changes.
- Plumbing. Covers pipes, valves, fixtures and gas piping.
- Electrical. Covers new or moved circuits.
- Mechanical. Covers HVAC work.
The city takes applications online through its Accela portal or KnoxPlans. Alteration permits ask for existing and proposed floor plans and written scope notes.
How Does the Permit Process Run?
A permitted alteration also triggers safety upgrades. The city requires AFCI protection on modified circuits and smoke and CO alarms in the home.
Can You Pull Your Own Permit as a Homeowner?
Sometimes. Each office sets its own conditions.
| Rule | City of Knoxville | Knox County |
|---|---|---|
| The home | Your owner-occupied primary residence | Your own residence, for your own use |
| Not allowed if you plan to | Sell, rent or lease it | Resell, rent or lease it |
| Limit | One application at one location in two years. The unlicensed route covers residential work under $3,000 | One home every two years |
| Who does the work | You may do electrical, plumbing and mechanical work only in an owner-occupied single-family home, with no owner permit at another address in five years | You must do the work yourself. Hired workers must show license proof |
LLC-owned property does not qualify in the city. Hire someone to work under your owner permit and the risk moves to you.

What Happens If You Skip the Permit?
- Work can stop. Farragut Codes halts jobs that start without a needed permit.
- Sale trouble. Unpermitted work can block financing when you sell.
- Lost permits. False information on a city permit can mean revocation and loss of the certificate of occupancy.
- Hidden defects. Rough inspections catch bad drains and wiring before tile covers them.
Does the Lead Paint Rule Apply to Your Bathroom?
Yes, if your home was built before 1978 and you hire a pro. Paid work that disturbs paint must follow EPA lead-safe rules. The firm must be EPA certified.
Six Checks Before You Sign a Remodeling Contract
- License. Verify it at verify.tn.gov.
- Insurance. Ask for the certificate.
- Written contract. Scope, price and dates on paper.
- Permit line. The contract names who pulls each permit.

FAQs About Bathroom Remodel Licenses and Permits in Knoxville
Where do I verify a Tennessee contractor license?
Use verify.tn.gov. Check the classification, dollar limit and expiration date.
What if my contractor says I do not need a permit?
Call the permit office yourself. It takes five minutes and protects your sale later.
Who pulls the permit, me or the contractor?
Your contractor normally does. State law puts each contractor’s license number on the permit.
Does a tub-to-shower conversion need a permit?
Yes. It moves the drain and valve, so it needs a plumbing permit. Framing changes add a building permit.
How much does a bathroom permit cost?
Fees depend on the office and the project value. We list permit fees as their own line in your written estimate.
Can I remodel my own bathroom without a contractor?
Often, as an owner-occupant. You still need permits where the work calls for them. See the homeowner rules above.
Does a handyman need a license in Knox County?
On jobs of $3,000 and up, yes. Plumbing and electrical follow their own trade rules, so a handyman may still need more.
How long does a permit take?
The city pages list no timeline for bathroom remodels. We never promise a date. Ask the office for current review times.
Do I need a permit to replace a vanity?
The cabinet and countertop do not. New plumbing connections might. Ask your office, and we will confirm for your address.
Do I need a permit to replace a bathtub in Knoxville?
Likely yes. A new tub usually means new valves or drain work, which needs a plumbing permit. Ask your permit office before you start.
