Tiny Homes in Kansas: Laws, Rules and Communities

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 Kansas, on a permanent foundation and where your city or county allows it. Kansas has no statewide building code for homes, so each city or county picks its own code, and Lawrence is one city that adopted the code's tiny house appendix. A tiny home on wheels has no category of its own in state law, and where you can live in one is up to local zoning. A 2026 state law, Senate Bill 418, in effect since July 1, 2026, requires every city and county to allow a lot as small as 3,000 square feet for a new single-family home under 2,500 square feet, and speeds up approval for homes that meet local zoning. Kansas has the 5th lowest cost of living of the 50 states, an income tax of 5.2 to 5.58 percent, an effective property tax rate of 1.21 percent (13th highest), and homeowners insurance averaging $5,455 a year.

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

In Kansas, your city or county decides almost everything about a tiny home, from zoning to which building code applies. A tiny home on a permanent foundation, meaning it is anchored to a base built into the ground, like a concrete slab or a crawl space, is treated as a house under whatever code your city or county uses. A tiny home on wheels, built on a trailer so it can be towed, has no category of its own in state law, and how it is labeled is not settled.

This guide covers local building codes and the tiny house appendix, homes on wheels, manufactured and modular homes, ADUs, the 2026 by-right housing law, septic, wells and water rights, and what we found when we looked for communities.

Quick facts

On a foundation (anchored to a base in the ground): a house, under the code your city or county has adopted.
Building code in force: no statewide code for homes. Each city or county adopts its own.
Tiny house rules: Appendix Q is not adopted statewide. Lawrence has adopted it. Whether SB 418's 2018 code rule brings it along is not settled.
New small homes: since SB 418 took effect on July 1, 2026, every city and county must allow lots as small as 3,000 square feet (subject to reasonable setbacks), a single-car garage and a 2018 version of the national residential code for a new single-family home under 2,500 square feet.
Minimum house size: none in state law that we found. Local zoning may set one.
On wheels (built on a trailer): no category of its own in state law. Local zoning decides where you can live in one.
ADUs (a second, smaller home on the same lot as a house): approved by right under SB 418 when they meet local zoning and the law's conditions. Whether the law makes cities allow them where zoning does not is not settled.
Septic (an underground system that treats wastewater where there is no city sewer): a county permit under the county sanitary code, or state minimum standards where a county has no code.

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

Yes, on a permanent foundation where local zoning allows it. On wheels, it depends on your city or county.

On a foundation, a tiny home is a house. It has to meet the building code your city or county uses, and it needs sewer or a septic system that meets county or state standards.
On wheels, we found no state law that allows or bans living full time in one. Local zoning decides. Douglas County, for example, allows a travel trailer or RV as a temporary second dwelling while you build your main home, for up to two years.
We found no statewide minimum house size. Ask your city or county whether it sets one.

The rules in plain words

Building code

Kansas does not enforce a statewide building code for homes. The state applies building codes to buildings on state owned property, and it leaves homes to cities and counties, which may adopt their own codes. That means the code edition, and whether you need a permit at all, depends on where the land is. Ask the city or county building department which edition it uses before you buy plans.

The tiny house appendix

The national residential code has an appendix with rules for tiny houses, called Appendix Q. It covers homes of 400 square feet or less, not counting lofts, and sets ceiling heights, loft sizes, and stair and ladder rules. In Kansas it applies only where a city or county adopts it.

Lawrence adopts the 2018 code and states that "Appendix Q, 'TINY HOUSES,' ... is hereby specifically adopted." Every appendix Lawrence does not name is deleted.
Topeka's code, which adopts the 2021 edition, names "Appendix AQ, Tiny Houses, in its entirety" in its adoption sentence. Ask the city how it applies.
SB 418 (below) requires every city and county to allow a 2018 version of the code for new single-family homes under 2,500 square feet. The law does not say whether the 2018 code's tiny house appendix comes with it. The city or county picks which 2018 version it allows, and one choice the law names is a version another local government adopted, such as Lawrence's, which includes the appendix. We found no court ruling or state guidance on the point. Until there is one, ask your building department in writing whether it will accept the appendix for your home.

If you would rather skip the loft, see tiny home layouts without a loft.

The 2026 by-right housing law (SB 418)

Senate Bill 418, the by-right housing development act, was approved by the Governor on April 7, 2026. The act says it takes effect on publication in the statute book, and the Kansas Secretary of State lists its effective date as July 1, 2026. In plain words, it does five things.

For a new single-family home under 2,500 square feet of livable floor area, on its own lot, every city, county and other local government must allow four things. These are the 2018 edition of the national residential code (as published, or the 2018 version it or another local government adopted, at the local government's choice), single-car garages, architectural finish on only one side of the house, and a minimum lot size of 3,000 square feet, "subject to any reasonable setback requirements." Local rules that conflict are void for that property.
Inside city limits, all land zoned for any kind of housing now also counts as zoned for single-family homes. Cities can still set reasonable setback, utility, subdivision, grading and platting rules.
Single-family homes (which the law defines to include duplexes), townhouses and ADUs that meet the local zoning code and the law's conditions must be approved by right, without discretionary review by a planning commission or zoning board. The conditions include no federal or state discharge permit or stormwater study, no more than 12 attached townhouse units, no added impervious surface, such as paving, that harms drainage into a special flood hazard area, and no site in a National Register historic district or under historic preservation review.
A complete application is approved automatically unless it is denied within 30 days, or 60 days when it needs a subdivision plat, or 90 days for a plat of more than 40 single-family homes. A subdivision plat is not approved this way unless it meets subdivision law.
When an owner asks to rezone their land to a single-family district, the city or county still publishes notice and holds a hearing, but neighbors no longer get mailed notice or a protest petition.

The law also lets a city or county opt in to third-party plan review and inspection when its own office takes more than 30 days. It does not override deed restrictions or HOA rules.

What it means for a tiny home. A new small home on a foundation, on its own lot, falls under the 2,500 square foot rule, so a city or county must allow a lot as small as 3,000 square feet for it, subject to reasonable setbacks. The law does not set a minimum house size and does not say a city or county must drop one, so ask whether yours has one.

Tiny homes on wheels

Kansas law has no category of its own for a tiny home on wheels, and how one is labeled is not settled. Three things point different ways.

The vehicle code defines a "travel trailer" as a towed vehicle "constructed primarily for recreational purposes." A tiny home on wheels sold for recreation fits that wording.
The Kansas manufactured housing act defines a "mobile home" as a towable structure that is not subject to the federal HUD code, is at least 8 feet wide and 36 feet long while traveling, is built on a permanent chassis and is designed to be used as a dwelling. A long tiny home on wheels built as a full-time home matches those words.
A shorter tiny home on wheels built as a home fits neither definition cleanly, and we found no state agency guidance that names tiny homes on wheels.

The label can decide where zoning lets you live in it and how it is titled and taxed. The manufactured housing act places its titles with the Division of Vehicles at the Kansas Department of Revenue, so ask the division how yours will be titled, and get your city or county's zoning answer in writing before you buy or build. For a homemade trailer, the Kansas Highway Patrol says to bring the trailer and its documents to a Highway Patrol VIN inspection station before you title and tag it, and that the documents needed depend on who built it, its size or weight, and its intended use.

We found no state law that allows or bans living full time in an RV or a tiny home on wheels. That is a local zoning question. Douglas County, for example, lets its zoning director approve a travel trailer or RV as a temporary second dwelling while your main home is being built, only while the building permit is valid, for up to two years, and with the county health department approving the sanitary setup.

Modular and manufactured homes

A manufactured home is built to the federal HUD code. Kansas law (K.S.A. 12-763) stops zoning from shutting manufactured homes out of an entire city or county, and stops it from keeping "residential-design manufactured homes" out of single-family districts just because they are manufactured. A residential-design home sits on a permanent foundation, is at least 22 body feet wide, and has a pitched roof and siding and roofing like a site-built house. Cities and counties can still set looks standards, and deed restrictions still apply. A tiny home is much narrower than 22 feet, so this law helps larger manufactured homes, not tiny ones.

The Kansas Housing Resources Corporation sets installation standards for manufactured homes and licenses the people who install them, and it can help settle disputes between owners and installers.

State law defines a modular home as one built in sections for a permanent foundation and certified by its maker to a nationally recognized building code. We did not find a state program that inspects or labels modular homes, so ask your building department what it needs to see.

ADU rules

Kansas has no law that sets size, parking or other standards for an ADU. SB 418 defines one as "a secondary housing unit that is subordinate to the primary dwelling unit on the same lot," which may have its own kitchen, bathroom and entrance, and it makes ADUs that meet the local zoning code approvable by right.

Whether SB 418 makes cities and counties allow ADUs where their zoning does not is not settled.

The law's wording ties by-right approval to projects that meet "the criteria outlined in the zoning code and land use regulations," and its definition covers projects that "comply with established land use regulations." Read that way, a city that does not allow ADUs in a zone does not have to approve one there.
The same law names ADUs in its purpose, alongside single-family homes and townhouses. A September 2026 report from The Beacon, carried by KCUR, said the law requires by-right ADU development without setting standards, and that the Unified Government of Wyandotte County and Kansas City, Kansas, was writing local ADU rules as a result.
Wichita still requires a conditional use permit for an accessory apartment as of October 2026.

No court or state agency has ruled on it that we found. The law's own wording leans toward the first reading, and the second comes from one local government's response, as reported. Until your city or county says otherwise, its current ADU rules decide what you can build, so ask for the answer in writing.

Cities set their own rules. Two examples:

Lawrence's Land Development Code, in effect since April 1, 2025, allows an ADU only as an accessory to a single detached house. In residential districts the owner must live in either the house or the ADU, with narrow exceptions. An ADU inside or attached to the house can be no more than 50 percent of the house's gross floor area, and one in or above a detached building, such as a garage, can fill that building if it meets the zone's size and setback rules. Whether it needs an extra parking space depends on the street, and it must be registered with the city before it is set up.
In Wichita, an accessory apartment needs a conditional use in the rural residential, single-family, two-family, manufactured housing and neighborhood office zones, under the zoning code the city shares with Sedgwick County. The Sedgwick County Commission adopted changes to the accessory apartment rules on September 16, 2026, and the Wichita City Council had not voted on them as of October 28, 2026.

Septic

Kansas leaves septic permits to counties. A state rule (K.A.R. 28-5-7) says private sewer systems must meet the county sanitary code the state health department approved, or, where a county has no code, the state's minimum design standards in KDHE Bulletin 4-2. County codes require a septic permit before you install a system. In slow-draining clay soils a lagoon may be the better fit, and a three-bedroom home's system can need from about 2,000 square feet for a tank and field to more than 6,000 square feet for a lagoon, according to K-State Research and Extension.

If you plan to use a composting toilet, ask the county sanitarian first how it affects the permit, since the home will still produce sink and shower water.

Wells and water rights

The Kansas Department of Health and Environment oversees how water wells are built and plugged, requires a well log for each one, and licenses water well contractors. Kansas law requires the chief engineer's approval for a new water right "for other than domestic use," so household use is outside that approval. Ask the county whether it requires its own well permit.

Where to start

Not sure which office covers your land? USA.gov's local government finder points to a directory of Kansas's counties and cities, with their websites and contacts.
Call the city planning department, or the county zoning office if the land is outside city limits. Ask whether tiny homes and ADUs are allowed, whether there is a minimum house size, and whether a tiny home on wheels can be lived in there. Get the answer in writing.
Ask the building department which code edition it uses, whether it has adopted the tiny house appendix, and how it applies SB 418's rules for homes under 2,500 square feet.
If the land is not on sewer, ask the county sanitarian or health department for a site evaluation and septic permit before you buy.
For a well, hire a contractor licensed by the Kansas Department of Health and Environment.
For a manufactured home, use a licensed installer and ask whether the home meets the 22 foot residential-design test for a single-family zone.
For a tiny home on wheels, ask the Kansas Division of Vehicles how it will be titled before you buy. If it was homemade, plan on a Kansas Highway Patrol VIN inspection first.
Before buying land, check the flood map, any deed restrictions and any HOA covenants, which SB 418 does not override.

Kansas has the fifth lowest cost of living of the 50 states, and housing is the lowest part of that index. The state income tax runs from 5.2 to 5.58 percent, and the effective property tax rate is 1.21 percent. Homeowners insurance averages $5,455 a year with $400,000 in dwelling coverage, compared with a U.S. average of $2,490. U.S. News ranks Kansas 20th in education and 31st in health care, and WalletHub ranks it 23rd happiest.

Rankings mix many factors, and statewide averages hide big differences between regions. The Kansas City suburbs, the Flint Hills and the High Plains of western Kansas differ in weather, land prices and local rules, so look at the area where you plan to live.

Tiny home communities in Kansas

We do not have a Kansas tiny home community on file yet. We could not confirm, on its own website, a tiny home community in Kansas where you can buy or rent a place. KCUR reports a tiny home community in Kansas City, Kansas, built for people leaving chronic homelessness, which is not listed here. The places we could check from directory listings were RV parks or a lake lot owners association whose own websites do not mention tiny homes or park models, or listings with no website at all. We also found no RV park whose own site says it takes tiny homes or park models for monthly or longer stays.

For now, the path we can point to in Kansas is your own land, where local zoning allows a small home.

Frequently asked questions

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

Yes, on a permanent foundation where local zoning allows it, if it meets the building code your city or county uses and has sewer or a permitted septic system. Kansas has no statewide building code for homes. For a tiny home on wheels, local zoning decides.

Does Kansas use Appendix Q for tiny houses?

Not statewide. Kansas has no statewide building code for homes, and Lawrence is one city that has adopted Appendix Q. SB 418 requires cities and counties to allow a 2018 version of the code for new homes under 2,500 square feet, but it does not say whether the tiny house appendix comes with it, and we found no court ruling or state guidance on the point. Ask your building department in writing whether it will accept the appendix for your home.

Can I live in a tiny home on wheels in Kansas?

It depends on your city or county. We found no state law that allows or bans living full time in one, and state law has no category of its own for it. Douglas County, for example, allows a travel trailer or RV as a temporary second dwelling while you build your main home, for up to two years. Get your county's answer in writing before you buy.

Does Kansas's 2026 housing law allow ADUs?

It makes ADUs that meet local zoning approvable by right, without discretionary review by a planning commission or zoning board. Whether it makes cities and counties allow ADUs where their zoning does not is not settled. KCUR has reported it that way and Kansas City, Kansas, was writing ADU rules, while Wichita still requires a conditional use permit. Ask your city or county what its current rules are.

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

Yes, if the home will not be on a sewer. County sanitary codes require a permit before you install a system, and where a county has no code, the state's minimum standards apply. Ask the county sanitarian or health department.
