Tiny Homes in Ohio: Laws, Rules and Communities

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

The short answer

Yes, you can live in a tiny home full time in Ohio. On a permanent foundation, a site-built or modular tiny home is a house under the Residential Code of Ohio, which applies statewide but is only enforced where a certified local building department covers your land. Ohio's code does not include the tiny house appendix yet. A 2026 draft update would add it, but it has not been adopted and has no start date. Ohio sets no statewide minimum house size; your township, county or city zoning decides that. A tiny home on wheels is usually titled as a travel trailer or other trailer at the county title office, and state law lets local zoning keep travel trailers and park models out of residential districts. There is no statewide ADU law. Ohio has the 19th lowest cost of living of the 50 states, an income tax of 2.75 percent on income over $26,050, an effective property tax rate of 1.36 percent (8th highest), and homeowners insurance averaging $2,080 a year.

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

In Ohio, two local offices decide most of what you can do. Zoning comes from your township, county or city, and some townships have no zoning at all. Building inspections come from a certified local building department, and where none covers the land, the state code still applies but no one reviews plans or inspects. 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 a house under the state code. A tiny home on wheels, built on a trailer so it can be towed, is a vehicle under state law.

This guide covers the state code and its pending tiny house update, homes on wheels, RV parks, modular and manufactured homes, city ADU rules, septic and wells, and where to find a community.

Quick facts

  • On a foundation (anchored to a base in the ground): a site-built or modular home is a house under the Residential Code of Ohio. HUD-code manufactured homes follow the federal code instead.
  • On wheels (built on a trailer): titled at the county title office, usually as a travel trailer if built to RV standards. Local zoning decides where you can live in one.
  • Building code in force: the Residential Code of Ohio, based on the 2018 International Residential Code, in effect since July 1, 2019 and amended March 1, 2024.
  • Inspections: only where a certified local building department covers the land. Where none does, no plans, inspections or certificate of occupancy are required.
  • Sleeping lofts (a raised sleeping area reached by a ladder or stairs): the tiny house appendix is not in Ohio's code yet. A 2026 draft update would add it, with no start date set as of November 2, 2026.
  • Minimum house size: none in state law. Local zoning may set one.
  • ADUs (a second, smaller home on the same lot as a house): no statewide law. Columbus, Cincinnati and Toledo have their own rules.
  • Septic (an underground system that treats wastewater where there is no city sewer): permitted by your local health district under state rules.

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

Yes. The answer depends on the home type and on your local zoning.

  • On a foundation, a site-built or modular tiny home is a house. It has to meet the Residential Code of Ohio, and it needs sewer or an approved septic system.
  • On wheels, we found no state law that allows or bans living full time in one. Local zoning decides, and state law lets townships, counties and cities keep travel trailers and park models out of residential districts.
  • Minimum house sizes are local. Some townships set large ones, so check before you buy land.

The rules in plain words

Building code

The Residential Code of Ohio covers one-, two- and three-family homes across the state. It adopts the 2018 International Residential Code with Ohio changes, took effect July 1, 2019, and was amended March 1, 2024.

Who enforces it depends on where you are. Local building departments certified by the state Board of Building Standards for residential work review plans and inspect homes. Where no certified residential department covers the land, the code says the owner does not have to submit plans, get approvals, request inspections or get a certificate of occupancy. The Board of Building Standards' online Building Department Look Up map shows which department, if any, covers an address.

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. It covers homes of 400 square feet or less, not counting lofts. Ohio's current code does not include it.

That may change, but not on a date anyone can give yet. On July 1, 2026, the Board of Building Standards released a draft update to the Residential Code of Ohio that would add the 2024 tiny house provisions as a new Section 329 and add definitions of a tiny house and a loft. The draft keeps the 2018 national code as its base. The Board sent the draft to the Governor's Common Sense Initiative office on August 21, 2026, revised it on September 23, 2026, and took comments through September 30, 2026. The Board says it will next decide whether to formally file the rules with the legislature's rule review committee (JCARR), and if it does, it will hold a public hearing before adopting them. As of November 2, 2026, its page lists the hearing as "Coming Soon." No effective date has been set, and the final text could still change.

What this means for you. Until an update takes effect, a tiny house on a foundation is reviewed under the current code, which has no tiny house section. Dayton's tiny home page warns that loft bedrooms may have trouble meeting the code's minimum room requirements. If your plans include a loft, ask the building department that covers your land how it will review it, and do not count on the draft section yet.

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

Minimum house size

Ohio sets no statewide minimum house size. Local zoning does.

  • Concord Township in Lake County requires 1,200 square feet for a one-story home in several residential districts.
  • Dayton says there is no minimum size for a home, though there are minimum sizes for certain rooms, and homes must be on a permanent foundation.

Tiny homes on wheels

Under Ohio law a travel trailer is a recreational vehicle up to 40 feet long, not counting the bumper and hitch. A park model, called a park trailer in the law, is built to the ANSI A119.5 standard, is 400 square feet or less when set up, and is "designed for seasonal or temporary living quarters." Travel trailers are titled through the county Clerk of Courts title office. A tiny home on wheels not built to RV standards may be titled as a trailer instead, since Ohio titles trailers that weigh over 4,000 pounds, so ask the title office.

We found no state law that allows or bans living full time in an RV or a tiny home on wheels. State law lets townships, counties and cities keep travel trailers and park trailers out of residential districts, so local zoning decides. Not every township has zoning. In Stark County, for example, about 12 of 17 unincorporated townships have adopted zoning.

  • Dayton says homes on wheels or without a permanent foundation are not allowed.

RV parks and campgrounds

Local health districts license RV parks and campgrounds every year, and the Ohio Department of Health approves the plans for new ones. State rules do not cap how long a guest can stay; that comes from each park's own rules and local zoning. Ask each park whether it is open in winter and whether it allows year-round stays.

Modular and manufactured homes

Modular homes, called industrialized units in Ohio, are built to the state residential code and carry an insignia from the Board of Building Standards. New rules for them took effect April 1, 2025.

HUD-code manufactured homes are overseen by the Manufactured Homes Program in the Ohio Department of Commerce, which licenses installers, inspects installations and regulates manufactured home parks. State law requires townships, counties and cities to allow a "permanently sited manufactured home" wherever single-family homes are allowed. To qualify, it must be on a permanent foundation and connected to utilities, have at least 900 square feet of living area and measure at least 22 feet wide and 22 feet long, have a 3:12 roof pitch, residential siding and eaves with gutters, be built after January 1, 1995, and sit outside a manufactured home park. A smaller home does not get that protection.

ADU rules

Ohio has no statewide ADU law. A few cities have their own.

  • Columbus council approved ADUs on November 24, 2025 (Ordinance 2526-2025, which allows them in all residential and apartment residential districts), and the city's handbook lists residential and mixed-use districts, up to 1,000 square feet or 65 percent of the main home, whichever is larger, and smaller than the main home. Its handbook says tiny homes and mobile homes do not qualify as ADUs.
  • Cincinnati has allowed one ADU per single-family lot since October 2, 2023. The owner or a designated responsible person must live on the property, and RVs do not qualify.
  • Toledo adopted ADU rules in September 2025: one ADU per lot, a footprint up to 60 percent of the main home's, the owner living in the main home, and no RVs, travel trailers or mobile homes.
  • Cleveland Heights is considering Ordinance 142-2026, which would allow ADUs. Council held its public hearing on October 15, 2026, and the city's page showed no vote as of November 2, 2026.
  • Akron has considered a zoning proposal that we could not confirm as adopted as of October 2026.

Where to start

  1. Not sure which office covers your land? USA.gov's local government finder points to a directory of Ohio's counties and cities, with their websites and contacts.
  2. Find out who zones your land: the township zoning inspector, the county where it zones, or the city or village. Ask whether the land is zoned, the minimum house size, and whether an RV, park model or tiny home on wheels can be lived in there. Get the answer in writing.
  3. Check the Board of Building Standards' Building Department Look Up map to see whether a certified residential building department covers the address. If one does, ask about plans and permits.
  4. If the land is not on sewer, contact the local health district about a septic permit before you build.
  5. For a private well, get a permit from the local health district and use a registered contractor.
  6. For a modular home, look for the Board of Building Standards insignia. For a manufactured home, use an installer licensed by the state's Manufactured Homes Program.
  7. Before buying land near water, check the flood map with the local floodplain administrator.

How Ohio compares with the other 49 states on the things people weigh before a move. Figures as of November 2026.

  • Happiness score (WalletHub 2026). 45.94 out of 100, 39th happiest
  • Cost of living (MERIC, Q2 2026; U.S. average is 100). 93.0, 19th lowest
  • State income tax. 2.75 percent on income over $26,050, plus $332 (2026); many cities and school districts add their own
  • Property tax, effective rate on owner-occupied homes (Tax Foundation, 2024 data). 1.36 percent, 8th highest
  • Homeowners insurance, average a year with $400,000 in dwelling coverage (NerdWallet 2026; U.S. average $2,490). $2,080
  • Health care (U.S. News 2026). 36th
  • Education (U.S. News 2026). 29th
  • Average temperature, 1991 to 2020. 51.7 degrees F
  • Average precipitation, 1991 to 2020. 41.1 inches a year
  • Sunshine in Columbus. 50 percent of daylight hours, 72 clear days a year
  • Outdoor recreation, share of the state economy (BEA 2024). 2.2 percent (U.S. 2.4 percent)
  • State parks. 76 state parks
  • People 65 and older (Census estimates, 2024). 19.1 percent (U.S. 18.0 percent)

Ohio's cost of living is below the national average, and homeowners insurance averages below the national figure. The state income tax rate is 2.75 percent above $26,050, though many cities and school districts add their own income tax, and the effective property tax rate is 1.36 percent. U.S. News ranks Ohio 29th in education and 36th in health care, and WalletHub ranks it 39th happiest.

Rankings mix many factors, and statewide averages hide big differences between regions. Lake Erie's shore and the southern hills have different weather, so look at the area where you plan to live.

Tiny home communities in Ohio

Few Ohio tiny home communities publish their details online. Rules, prices and openings change, so contact each one directly before you plan around it.

  • Cedar Springs Tiny Village, New Paris and Millersburg. Its website says residents own certified tiny homes on wheels and lease their sites, from $520 a month on leases of 12 months or longer at New Paris. The community told us in October 2026 that residents can live at either location year-round, that New Paris has a wait list and that Millersburg has sites available.

Frequently asked questions

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

Yes. On a permanent foundation, a site-built or modular tiny home is a house under the Residential Code of Ohio, 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.

Does Ohio have a minimum house size?

Not in state law. Townships, counties and cities set their own minimums through zoning, and some are large. Ask your zoning office.

Does Ohio use Appendix Q for tiny houses?

Not yet. Ohio's code is based on the 2018 national code without the tiny house appendix. A 2026 draft update would add the 2024 tiny house provisions, but as of November 2, 2026 the Board of Building Standards had not formally filed it for rule review or held its public hearing, and no effective date had been set.

Do I need a building permit for a tiny house in Ohio?

Only where a certified local building department covers the land. Where none does, the state code still applies, but no plans, inspections or certificate of occupancy are required. Zoning and health district permits can still apply.

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

It depends on your local zoning. State law lets townships, counties and cities keep travel trailers and park models out of residential districts, and some townships have no zoning. Ask and get the answer in writing before you buy.

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

Yes, if the land is not on sewer. Your local health district issues the permit under state household sewage rules.
