Tiny Homes in Tennessee: Laws, Communities and Real Tours

Updated November 4, 2026. Some laws may have changed since then. Confirm with your city or county before you buy land or a home.

The short answer

Yes, you can live in a tiny home full time in Tennessee. On a permanent foundation it is a house under the state residential code or your local code, and the state code includes the national tiny house appendix. On wheels, local zoning decides where you can live in one. We found no statewide ADU law, and a 2026 bill to create one stalled, so each city sets its own ADU rules. Tennessee has the 9th lowest cost of living of the 50 states, no state income tax, an effective property tax rate of 0.52 percent (10th lowest), and homeowners insurance averaging $4,220 a year. We have filmed more than a dozen tiny homes here.

On this page. Quick facts, the rules in plain words, where to start, living in Tennessee, communities, our tours and common questions.

Tennessee has a statewide residential code, but who enforces it depends on where you are. Larger cities and counties enforce their own codes, the State Fire Marshal's Office enforces the state code in other places, and some counties and cities have voted out of residential code enforcement. A tiny home on a permanent foundation, meaning it is anchored to a base built into the ground, like a concrete slab or piers, is treated as a house under whichever code applies. A tiny home on wheels, built on a trailer so it can be towed, is a zoning question for your city or county.

This guide covers how the code works and who enforces it, the city ADU rules, septic, where the communities are, and the Tennessee homes we have toured.

Quick facts

  • On a foundation (anchored to a base in the ground): treated as a house under the state residential code or the code your city or county enforces.
  • On wheels (built on a trailer): we found no state law that allows or bans living full time in one, so local zoning decides.
  • Building code in force: the state uses the 2018 International Residential Code with amendments. Nashville, Knoxville and Sevier County use the 2024 code. In some counties and cities there is no residential code enforcement at all.
  • Sleeping lofts (a raised sleeping area reached by a ladder or stairs): covered by the tiny house appendix, which is part of the state residential code. Cities and counties with their own codes choose their own appendices. Knoxville, Knox County, Sevier County and Rutherford County include it; Nashville, Memphis and Shelby County, and Chattanooga do not.
  • ADUs (a second, smaller home on the same lot as a house): we found no statewide law. Nashville, Knoxville and Chattanooga each have their own rules.
  • Septic (an underground system that treats wastewater where there is no city sewer): you need a permit to build a septic system. It comes from the state, or from the county in nine counties, and is separate from building codes.

Can you live in a tiny home full time in Tennessee?

Yes. The answer depends on the home type and on your city or county.

  • On a foundation, a tiny home is a house. It has to meet the code that applies where you build, and it needs an approved septic system or sewer.
  • On wheels, we found no state law that allows or bans living full time in one. Local zoning decides, so ask your planning office before you buy land.
  • The state residential code includes the tiny house appendix, which has rules made for homes of 400 square feet or less, such as lofts and ceiling heights. Where a city or county enforces its own code, ask whether it uses the appendix.

The rules in plain words

Building code

The state's residential code is the 2018 International Residential Code with amendments and Appendix Q, in effect since July 16, 2020. Where it is enforced, and by whom, depends on the local government.

  • Exempt. A city or county can enforce its own code instead of the state's, generally one within seven years of the latest edition, unless the State Fire Marshal approves another version in writing. Nashville, Knoxville and Knox County, Chattanooga, Memphis and Shelby County, and Sevier and Blount counties all enforce their own codes.
  • State enforcement. Where a local government has not taken over, the State Fire Marshal's Office enforces the state code.
  • Opt out. A county or city can vote out of residential code enforcement by a two-thirds vote of its governing body. An opt-out vote expires 180 days after the next election for that governing body, and if the new body does not vote to opt out again, the State Fire Marshal starts enforcing the code. The State Fire Marshal's list shows 37 opt-out counties as of October 26, 2026, plus a number of cities. The list changes, so check it for your county. Even in an opt-out area, an owner can ask the State Fire Marshal for an inspection. Ask your county whether electrical and septic permits are required.

Codes differ among the big cities. Nashville adopted the 2024 codes effective July 16, 2025, and Knoxville adopted the 2024 residential code in October 2024. Sevier County moved to the 2024 codes on July 1, 2026. Memphis and Shelby County use the 2021 code, and Chattanooga uses the 2018 code.

The tiny house appendix

The national code has an appendix with rules for tiny houses, called Appendix Q in the 2018 code and Appendix BB in the 2024 code. Whether it applies to your home depends on who enforces the code where you build, and the answer is different from place to place.

  • Where the State Fire Marshal enforces the code, it applies. The state rule adopts the 2018 code "and Appendix Q."
  • Where a city or county enforces its own code, its own adoption decides. Knoxville adopted the 2024 code with Appendix BB in October 2024. Knox County includes Appendix Q in its 2018 code, which applies where the county enforces the code. Sevier County adopted the 2024 code with Appendix BB, in effect July 1, 2026. Rutherford County's tiny home construction guidelines use Appendix BB of the 2024 code, on a permanent foundation with an approved septic system, for homes of 400 square feet or less, not counting lofts.
  • Other large places with their own codes have not adopted it. Nashville's 2024 code lists five other appendices but not Appendix BB. Memphis and Shelby County adopted the 2021 code with no appendices. Chattanooga's 2018 code lists four other appendices, not Appendix Q. We could not find Blount County's adopted code online.
  • Where a county or city opted out, there is no residential code enforcement at all.

What this means for you. Without the appendix, a loft is held to the main code's rules for stairs, ceiling heights and emergency exits, which can rule out a loft ladder. Ask the building office which code edition and appendices it enforces before you design a loft.

Some cities define tiny houses in their own zoning. Union City, for example, defines a tiny house as under 900 square feet of heated living space on a permanent foundation. If you would rather skip the loft ladder, see tiny home layouts without a loft.

A state inspection program for preassembled tiny homes

In 2021 the State Fire Marshal's Office announced an inspection program for preassembled tiny homes built off site, either on a chassis or set on a permanent foundation, through its Modular Building Program. Homes that pass get a decal showing they meet the state's building and electrical codes. The rule behind it is still in the state's published rules. Since June 29, 2021, the modular building rule lets a unit its maker calls a tiny home be built to the state residential code if it is on a fixed chassis, is not a HUD-code home, has permanent water and sanitation, and has an engineered anchoring system for permanent installation. The office's current Modular Building Program page does not mention tiny homes, so ask the office how to apply before you plan around it. If a tiny home is built on site where a city or county enforces its own code, that local office permits and inspects it. Local zoning still decides where the home can go.

Tiny homes on wheels

A state rule defines a park trailer, often called a park model, as a unit on a single chassis, on wheels, "designed to provide seasonal or temporary living quarters," and no more than 400 square feet when set up. We found no state law that allows or bans living full time in an RV or a tiny home on wheels. Where you can live in one, and for how long, is up to local zoning.

Modular and manufactured homes

Modular homes built to the state code go through the State Fire Marshal's Modular Building Program, under the Tennessee Modular Buildings Act. The same office licenses manufacturers, retailers and installers of HUD-code manufactured homes and inspects their installation.

ADU rules

We found no statewide ADU law in Tennessee. A 2026 bill to regulate ADUs statewide (HB 2031 and SB 2131) was taken off notice in a House subcommittee on March 11, 2026, and had no further action before the 2026 session ended. Cities set their own rules.

  • Nashville allows one detached ADU on a lot with one single-family home, in the Urban Services District and other areas where its zoning allows them. Living space is capped at 700 square feet on lots under 10,000 square feet and 850 square feet on larger lots, and the owner must live in one of the two homes.
  • Knoxville allows one ADU on a lot of at least 5,000 square feet with one single-family home. It can be inside, attached to or separate from the house, but it cannot be larger than 40 percent of the house's floor area or have more than two bedrooms. The owner must live in one of the two homes, and the ADU needs one off-street parking space.
  • Chattanooga allows one ADU of up to 800 square feet, measured from the outside walls with conditioned lofts counted, on a lot with a detached single-family home. There is no minimum parking for the ADU and no owner occupancy requirement. The ADU must sit on a permanent foundation, and recreational vehicles and shipping containers are not allowed as ADUs.

Check your HOA covenants and deed restrictions too.

Building your own home

State law lets a property owner build one home every two years for their own use without a contractor's license, according to the State Fire Marshal's Office. The home cannot be sold, leased or rented under that rule.

Where to start

  1. Not sure which office covers your land? USA.gov's local government finder points to a directory of Tennessee's counties and cities, with their websites and contacts.
  2. Look up your county or city on the State Fire Marshal's jurisdiction list to see whether it enforces its own code, uses the state program, or has opted out.
  3. Call the planning and zoning office for your land. Ask what zoning the land has, whether a home of your size and type is allowed, and whether a tiny home on wheels can be lived in there. Get the answer in writing.
  4. If the land is not on sewer, start with the septic permit. The Tennessee Department of Environment and Conservation handles it, except in nine counties that run their own programs: Blount, Davidson, Hamilton, Jefferson, Knox, Madison, Sevier, Shelby and Williamson.
  5. For a private well, you or your licensed driller must file a Notice of Intent with the state, at least one hour before drilling by fax or email, or postmarked five days ahead by mail.
  6. Pick the home type that fits the answers: site-built or modular on a foundation, a manufactured home, a park model, or a tiny home on wheels in a community or park.
  7. For a factory-built or preassembled home, contact the State Fire Marshal's Modular Building Program. For a manufactured home, use a state-licensed installer.

Frequently asked questions

Is it legal to live in a tiny house in Tennessee?

Yes. On a permanent foundation, a tiny home is a house and must meet the code that applies where you build, with sewer or an approved septic system. For a tiny home on wheels, we found no state law that allows or bans full-time living, so local zoning decides.

Can I park a tiny home on wheels on my own land in Tennessee?

It depends on your county or city. Zoning decides whether you can live in one on your land and for how long. Ask your planning office and get the answer in writing before you buy.

Does Tennessee use Appendix Q for tiny houses?

Yes, where the State Fire Marshal enforces the code, since the state code adopts the 2018 code with Appendix Q. Cities and counties that enforce their own codes decide for themselves. Knoxville, Knox County, Sevier County and Rutherford County include it; Nashville, Memphis and Shelby County, and Chattanooga do not. Areas that opted out have no residential code enforcement. Ask your local building office which code edition and appendices it enforces.

Can I build an ADU in Tennessee?

We found no statewide ADU law, so it depends on your city or county. Nashville allows detached ADUs of up to 700 or 850 square feet depending on lot size, with the owner living on the property. Knoxville allows one ADU of up to 40 percent of the house's floor area, with the owner living on the property and one off-street parking space. Chattanooga allows ADUs of up to 800 square feet on a permanent foundation, with no owner occupancy requirement.

Do I need a septic permit for a tiny home in Tennessee?

Yes, if the land is not on sewer. You need a permit to build a septic system. The Tennessee Department of Environment and Conservation issues it, except in nine counties that run their own programs. It is a separate program from building codes.
