No obligation. A real person answers, walks the job with a free consultation, and gives you a straight price.

The permitting authority is Knox County Codes Administration. Start there.

Most contractor pages about permits are vague on purpose, because being specific means being accountable for the specifics. Here is what Knox County Codes Administration actually publishes, with nothing added.

The office

City County Building, Suite 547, 400 Main Street, Knoxville, TN 37902. Phone 865-215-2325. Its stated mission is protecting the safety, health, welfare and property of Knox County citizens through administration, education and enforcement of building regulatory codes. Check the county's own site for current office hours.

The permit categories that touch a bathroom

Knox County references remodeling and alteration, plumbing, electrical and mechanical permits. A bathroom remodel can involve all four, depending on scope: alteration for the room itself, plumbing if anything moves, electrical for lighting and outlets, mechanical for ventilation. Whether your specific job triggers any of them is the county's call, and the way to find out is the phone number above.

Who can apply

Both homeowners and licensed contractors can apply. Homeowners must provide an affidavit, and the county publishes a Homeowner Permit Affidavit form for it. There is also a Worker's Comp Exemption Affidavit on the same forms list.

You may not need to go downtown

Knox County states it directly: if the permit is filled out and submitted online, you do not need to visit the office.

Fees

The county publishes a schedule of fees, including one effective July 1, 2023. Read the current one on the county's own site rather than trusting a number republished elsewhere, including here.

Inspections

Knox County runs a Permit Inspection Lookup where you can view inspection results and look up scheduled inspections. If your job is permitted, inspections are part of it and they sit in the schedule, which is worth knowing when you are planning around the room being out of service.

Which codes

Every construction handout Knox County Codes Administration publishes carries a 2018 prefix, and the list names 2018 IBC ADA Information, 2018 Mechanical Ventilation, 2018 Energy Requirements, 2018 Gas Pipe Sizing and 2018 Smoke & Carbon Monoxide Alarms among others. Two of those are directly relevant to a bathroom: mechanical ventilation, because a bathroom exhaust is a code item and not a preference, and the alarm requirements, which get looked at when electrical work happens. The county is the authority on what applies. This page is a starting point and a phone number.

What to ask on your own call

  • Does this specific scope need a permit, and which categories
  • Who is pulling it, you or the contractor
  • What inspections come with it, and at which stages
  • What that does to the schedule

The first question goes to Knox County at 865-215-2325. The rest are worth raising with the crew at the free consultation. Call (865) 269-6735.

Frequently asked

Who issues building permits for a bathroom remodel around Knoxville?
Knox County Codes Administration, at the City County Building, Suite 547, 400 Main Street, Knoxville, TN 37902, on 865-215-2325. Check their office hours on the county's own site before you drive anywhere.
Does my bathroom remodel need a permit?
The county decides that, not this page and not a contractor's website. What is published is that remodeling and alteration, plumbing, electrical and mechanical are all permit categories, which covers most of what a bathroom remodel touches. Call 865-215-2325 and describe your job, and you will get an answer that applies to you.
Can I pull the permit myself?
Knox County states that both homeowners and licensed contractors can apply, and that homeowners must provide an affidavit. The county publishes a Homeowner Permit Affidavit form for that. Whether you should is a different question from whether you can, and it is worth raising on the call so everyone knows who is doing it.
Do I have to go downtown?
Not necessarily. Knox County states plainly that if the permit is filled out and submitted online, you do not need to visit the office.
What do permits cost?
Knox County publishes a schedule of fees, including one effective July 1, 2023. The amounts are on the county's own documents rather than here, because a fee schedule someone else maintains is not a number this page should be repeating from memory.
How do I find out when my inspection is, or how it went?
The county runs a Permit Inspection Lookup that shows inspection results and scheduled inspections.
Which code edition applies?
Every construction handout Knox County Codes Administration publishes is on the 2018 cycle, and the list names 2018 IBC ADA Information, 2018 Mechanical Ventilation, 2018 Energy Requirements and 2018 Smoke & Carbon Monoxide Alarms among others. The county is the authority on what applies to your project.
Do you handle the permit for me?
This page does not promise that, because the operator does not publish it. Ask on the call who is pulling the permit for your job and get a direct answer rather than an assumption. Either way the county is the one issuing it.

Questions about scope, not about code?

One call, a free consultation at the house, and a straight price. No pressure, no obligation.
