Custom Plans in Ohio

Barndominium plans are easy to buy online and harder to build from. A stock plan from a plan store is a floor plan and a set of elevations drawn for no site in particular; it rarely shows a foundation for your frost depth, a roof for your snow load or a septic layout for your bedroom count. We draw custom barndominium plans from scratch and adapt stock barndominium floor plans you already like, then turn either into a complete set for your parcel. The Residential Code of Ohio sets a 115 mph design wind speed statewide and leaves frost-line depth and ground snow load to the local jurisdiction, so we get those figures from the department that covers your land before the framing is drawn. The result is one set of barndominium plans for Ohio that a kit supplier can price, a lender can appraise from and a certified building department can review.

Custom Plans: how the work runs

Four stages, in this order. The sequence matters more than it looks: getting engineering and permitting settled before anything is fabricated is what keeps a build from stalling.

1

Stock or custom barndominium plans

Bring a stock plan you like, a sketch, or just a list of rooms and a shop size. Stock plans are the fastest start and work well when the layout already fits your life. Custom plans make sense when the site, the view, a large shop bay or a specific room count does not match anything in a catalogue. Either way we start with how you will live in it and what you want to park in it.

2

Fit the plan to your parcel

We place the building on your land with the driveway, well, septic area and setbacks, then collect the design criteria for your location. The Residential Code of Ohio fixes the wind speed and ice-barrier requirement statewide. Frost depth and ground snow load come from the local jurisdiction, and those decide the footings and roof framing.

3

Draw the complete set

Floor plan, elevations, sections, foundation plan, framing and roof plans, and the design criteria on the cover sheet. If you are building from a kit, the supplier's frame drawings are coordinated with ours. Where a sealed sheet is wanted, a licensed Ohio professional engineer engaged for the project seals it; we do not.

4

Submit, price and build

Where a certified residential building department covers your land, the set goes to it for review, and the septic design goes to the health district. The same set is what kit suppliers and trades quote from, so the prices you collect compare like with like. From there we can supply a kit, build the shell or take it through as a turnkey home.

A floor plan is not a building plan until it knows where it is

Most barndominium floor plans sold online show rooms, doors and a roofline. They do not know your frost depth, your ground snow load or how many bedrooms your septic system has to be sized for. In Ohio those answers come from three places. The Residential Code of Ohio sets a 115 mph design wind speed statewide. The local jurisdiction fills in frost-line depth and ground snow load. The health district sizes the septic system by bedroom count, at 120 gallons per day per bedroom with a 240-gallon minimum under the state rule. We draw those answers into the plan before it goes to a kit supplier or a building department, which is far cheaper than finding them at review.

Where we deliver custom plans

In Ohio the code is the same everywhere, but who enforces it is not. A city, a village, a township or the county may run the certified building department that reviews your drawings, and in some unincorporated areas none does. Township and county zoning, the health district that permits your septic system and well, and the frost depth and snow load your department publishes all change from one parcel to the next. We work out which of them apply to your land before anything is priced.

Every locality we build in has its own reviewer, its own fee schedule and its own filled-in design criteria. The service area pages set out what each one publishes.

What actually decides the price

Square footage is the number everyone leads with, and it is rarely the one that moves a barndominium budget. These four do.

  • Stock plan, adapted plan or fully custom

    Adapting a stock plan you already own is the smallest scope. Moving walls, adding a shop bay or changing the roof shape adds work, and a plan drawn from a blank page adds the most. We tell you which one your list of changes really is before we start.

  • Size, shape and the shop

    A simple rectangle with one roofline is the most straightforward set to draw and to build. Wraparound porches, lofts, a second storey, tall shop doors and mixed ceiling heights each add sheets and details, and each one changes the frame.

  • Loads and foundation for your site

    The footings follow the frost depth your local department publishes, and the roof follows its ground snow load together with the statewide wind speed. A sloping site, a walkout or poor soil adds foundation detail that a flat-site stock plan never shows.

  • Sealed sheets and review comments

    Ohio does not require a seal on plans for a one-, two- or three-family home, but a kit supplier, a lender or a reviewer may still want one. An independent licensed professional's fee for that, and any revisions after plan review, are part of the plan budget.

Custom Plans in Ohio: common questions

8 questions we get asked most often about building in Ohio. If yours is not on the list, ask it directly.

Start your project
What is the difference between stock and custom barndominium plans?
A stock plan is a finished design sold to many buyers. It is quick and affordable to start from, but it was drawn for no particular site. A custom plan is drawn for you and your land, around your room list, your shop and your view. Most of our clients land in between: a stock barndominium floor plan they like, adapted for their parcel, their loads and the changes they want.
Can I use barndominium plans I bought online in Ohio?
Usually, once they are adapted. The Residential Code of Ohio uses a 115 mph design wind speed statewide, and your local jurisdiction sets the frost depth and ground snow load. A plan drawn for a warmer market may need deeper footings, heavier roof framing or more bracing. It also needs a site plan, a foundation for your ground, and a bedroom count the septic design can match. We check the plan against all of that and redraw what needs redrawing.
Do barndominium plans in Ohio need an engineer's or architect's seal?
Not by law for a one-, two- or three-family home. Ohio lets someone who is not an architect or engineer prepare residential plans. A seal can still be wanted for other reasons: a kit supplier's frame design, a lender, or a reviewer asking about a particular detail. When that happens, a licensed Ohio professional engineer who is independent of us reviews and seals those sheets. We do not describe ourselves as architects or engineers, and we do not seal anything.
What goes into a complete plan set for a barndominium?
A site plan with the building, drive, well, septic area and setbacks. A foundation plan to the local frost depth. Floor plans, elevations and building sections. Framing and roof plans, or the kit supplier's frame drawings coordinated with ours. A cover sheet with the design wind speed, snow load and frost depth. Door and window schedules, plus the energy details the reviewer needs. The health district may also ask for building and plumbing plans with the septic application.
Does every building department in Ohio review plans?
No. Ohio has one statewide residential code, but whether your build is plan-reviewed and inspected depends on whether a building department certified by the Board of Building Standards for residential work covers your land. Where none has jurisdiction, ORC 3791.04 says the owner is not required to submit plans for approval. The code still applies to the house, and the health district still issues the septic and well permits, so a complete set is worth having either way.
How long is an approved plan good for?
Under ORC 3791.04, plan approval lapses if work does not begin within twelve months of approval, or if work stops for more than six months. Extensions are available. That is one reason we line up financing, the kit order and site work before the set is submitted, so an approval is not sitting unused.
How many bedrooms should I plan for if I am on septic?
As many as you will really use, because the bedroom count sizes the system. Ohio's sewage treatment rules size a household system at 120 gallons per day per bedroom, with a minimum of 240, and the local board of health can require more. A fourth bedroom or a bonus room that reads as one can mean a bigger system and a bigger drain field area on the lot. We settle the bedroom count with you before the septic design starts.
Can you turn my plans into a kit order or a full build?
Yes. A complete set is exactly what a kit supplier needs to quote accurately, and it is what our crews and trades build from. You can take the plans and build yourself, buy a kit and erect it with us, or have us carry the whole project through as a turnkey home under one written contract. The plans work either way.
