Cost guide

How much does it cost to build a barndominium in Maryland?

We do not publish a price list, because on a Maryland barndominium the land and the approvals move the number more than the floor plan does: the driveway, the pad, how far power has to run, the perc test, the septic system and the well, what the building department asks for and the fees that come with the permit. The cost guide sets out published third-party cost data, every figure with its source, and walks through what pushes a build to the top or bottom of the range.

How a build runs

Land to keys, in four stages

Barndominium projects go wrong early, at zoning, access and site checks, long before anyone pours concrete. Here is the order we work in and why.

Start your plans

Start the survey. We take your program, the rooms, the shop bay, how you actually want to live in it, and start a floor plan drawn for your land rather than pulled off a shelf, whether you bring a sketch, a saved layout or a blank sheet. This is where most of the useful decisions get made.

That is how a build runs. Step one is a plan drawn for your land, and that starts with the survey.

Building a barndominium in Maryland

Four things shape a Maryland build before anyone pours concrete.

Permits are county-run

Maryland homes are built to the Maryland Building Performance Standards, which adopt the International Residential Code; the state edition in force today is the 2021 code. The Maryland Department of Labor adopts the statewide code, and your county (or, inside some towns, the town) issues the building permit, reviews plans, inspects the work and issues the occupancy certificate. Counties can amend the state code, but they cannot weaken its energy-efficiency, wind-design or home-sprinkler requirements.

How we handle permitting

The Chesapeake Bay Critical Area

Land within 1,000 feet of tidal water or tidal wetlands is usually in the Chesapeake Bay Critical Area. There you face a buffer of at least 100 feet from the water, lot-coverage limits (commonly 15 percent) and, in resource conservation areas, one home per 20 acres. On the Eastern Shore, in Southern Maryland and in Anne Arundel County, check the county’s Critical Area map before you buy; we go through it with you before anything is drawn.

Can you build a barndominium in Maryland?

Perc test, septic and well

Before a county will issue a building permit for a home on septic and a well, the health department must issue the septic permit and the well permit. Where the water table rises seasonally, the perc test is run in the wet season. New homes in the Critical Area need a nitrogen-removing (BAT) septic system; outside it a conventional system is allowed unless the county requires BAT. The well is drilled by a Maryland-licensed well driller.

Site preparation

Home and shop under one roof

Shop bays, tall doors, equipment and RV storage, guest wings and mudrooms. A shouse puts the living space and a working shop in one new building, planned around how you actually use both, in a pole barn or steel frame.

Shouses

Building in Maryland: common questions

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

Start the survey
Do you build barndominiums across Maryland?
Yes. Maryland Barndominium Builders plans and builds barndominiums, pole barn homes and metal building homes on private land across Maryland. Most of that land is outside the Baltimore and D.C. suburbs: Frederick County and Carroll County; Washington County, Allegany County and Garrett County in Western Maryland; Harford County and northern Baltimore County; Charles, Calvert and St. Mary’s Counties in Southern Maryland; and the farm country of the Eastern Shore, from Cecil County down to Worcester County. See the areas we serve, or start the survey with your parcel.
Can I build a barndominium in Baltimore, Columbia or Silver Spring?
Rarely inside those places themselves, to be honest. A barndominium needs room for the building, the shop bay, the driveway and often a well and a septic system, and there is very little open acreage inside Baltimore City, Columbia, Ellicott City, Silver Spring, Aspen Hill, Germantown or Severn. For people who live there the land is further out: for Baltimore, northern Baltimore County, Harford County and Carroll County; for Columbia and Ellicott City, western Howard County and Carroll County; and for the Montgomery County suburbs, upper Montgomery County and Frederick County. If you already own an in-town lot, tell us about it in the survey and we will say plainly what it can take.
Do you build on land I already own?
Yes, and that is most of the work: farmland, family land, wooded acreage and newer rural lots outside town. We walk the property with you, check access for concrete trucks and delivery equipment, and work out where power, a well and a septic system can go. If you have not bought land yet, we can look at a parcel with you before you close on it, which matters in Maryland because a lot that fails its perc test, or sits close to tidal water, may not take the house you have in mind. Tell us where it is in the survey.
Are there barndominiums for sale in Maryland, or do I have to build one?
Finished barndominiums do come up for resale, but not often, and rarely where you want one. Most people searching for a barndominium for sale in Maryland end up buying one of three things: a barndominium kit (the steel or pole barn building package) erected on their own land, a dried-in shell they finish themselves, or a turnkey build from bare land to keys. Our barndominium kits page sets out what each option includes and how prefab, modular and manufactured homes differ from a kit.
Is a barndominium kit the same as a prefab, modular or manufactured home?
No. A barndominium kit is a package of parts, the frame, roof and wall panels, trim and fasteners, delivered to your land and put up there on a foundation poured on site. A modular home is built in a factory, certified by the Maryland Department of Labor and marked with a green state label (Public Safety Article §12-306); a manufactured home is built to the federal HUD code on a permanent chassis and carries a red HUD label (§12-301). A steel or pole barn kit is neither: it is erected on your land and permitted and inspected by your county like any site-built home. Our barndominium kits page explains what that means for permits, financing and resale.
What is the difference between a barndominium, a pole barn home and a metal building home?
Barndominium describes what the building is: a home, usually open-plan and often with a shop or garage bay under the same roof. Pole barn home and post-frame home name the same structural system: large wood posts, spaced wide apart, carry the roof and wall loads, with girts and purlins running between them. A metal building home is framed in steel instead. Inside, any of them is finished like a conventional house. We build both pole barn and steel-frame barndominiums.
How much does it cost to build a barndominium in Maryland?
We do not publish a price list, because on a Maryland barndominium the land and the approvals move the number more than the floor plan does: the driveway, the pad, how far power has to run, the perc test, the septic system and the well, what the building department asks for, and the fees that come with the permit. Our Maryland barndominium cost guide sets out published third-party cost data with its sources. For a number against your own parcel, start the survey and we will put a written quote in front of you before anything is ordered.
Is a barndominium cheaper to build than a traditional house?
Sometimes, but not automatically. A pole barn or steel shell spans wide without interior load-bearing walls, but a barndominium is finished inside like any house, and insulation, drywall, cabinets, flooring, plumbing, electrical and HVAC cost much the same whatever frame they sit in. The land work (driveway, pad, power, well and septic) often decides the comparison. Our barndominium vs. house cost guide sets the two side by side with cited data.
What is included in a barndominium kit, and what does it leave out?
A kit is typically the structural shell: the frame, roof and wall panels, trim and fasteners, and the doors the package names. The slab, site work, delivery and erection, insulation, and the whole interior finish usually sit outside it, so the kit price is only part of what the finished home costs. Ask exactly what a kit quote covers before comparing two. Our barndominium kits page and the cost guide walk through the line items.
What size barndominium can I build on my budget?
That depends on the finish level and on the land work more than on square footage alone, which is why we do not publish a price per square foot of our own. Our size-for-budget guide works through the trade-offs using published third-party cost data, and the survey is where you tell us the budget and the parcel so we can put a written quote against both.
Can you build a shouse, with living space and a shop under one roof?
Yes. A shouse, or shop house, puts a working shop or equipment bay and the living space under one roof, and it is one of the most common reasons people choose a barndominium. The shop door size, the ceiling height in the bay and how the living space is separated from it are the decisions that shape the plan. We build shouses as new homes on land; a shop added beside an existing house is a different kind of project that we do not take on.
Can I finance a barndominium like a normal house?
Often, but not with every lender. Some treat a barndominium as ordinary residential construction; others are less familiar with it, and the appraisal is where that tends to show. We can provide the plans, specifications and cost breakdown a lender asks for during approval and the construction draw process. Our Maryland barndominium financing guide walks through the options.
Do I need a building permit for a barndominium in Maryland?
Yes. A barndominium is a house under the building code. Maryland homes are built to the Maryland Building Performance Standards, which adopt the International Residential Code; the state edition in force today is the 2021 code (COMAR 09.12.51), and the state has proposed moving to the 2024 edition. The Maryland Department of Labor adopts the statewide code, and your county (or, inside some towns, the town) issues the building permit, reviews plans, inspects the work and issues the occupancy certificate (Public Safety Article §12-505). Waldorf, Columbia, Ellicott City, Germantown and Silver Spring are not incorporated, so the county handles them. Each county adopts a new state edition on its own timetable, within 12 months of the state, so ask the county which edition applies to your permit. Counties can amend the state code, but they cannot weaken its energy-efficiency, wind-design or home-sprinkler requirements (§12-504). Snow load, wind speed and frost depth are set for your site by the county building official. Our permitting service explains how we handle it, and can you build a barndominium in Maryland? covers the wider question.
Does a new barndominium in Maryland need fire sprinklers?
Yes. New one- and two-family homes in Maryland need an automatic fire sprinkler system (IRC R313.2); a county can relax this only for a home that is not connected to the electric utility (Public Safety Article §12-504). It applies whatever the frame, so it belongs in the budget from the start, which is why the cost guide covers it.
What if my land is near the Chesapeake Bay or a tidal creek?
Then check the county’s Critical Area map before you buy. Land within 1,000 feet of tidal water or tidal wetlands is usually in the Chesapeake Bay Critical Area (Natural Resources Article §8-1807). There you face a buffer of at least 100 feet from the water, lot-coverage limits (commonly 15 percent) and, in resource conservation areas, one home per 20 acres (COMAR 27.01.02.05). A new home there also needs a nitrogen-removing (BAT) septic system, maintained every year (COMAR 26.04.02.07). It matters most on the Eastern Shore, in Southern Maryland and in Anne Arundel County, and we go through the map with you before anything is drawn.
Will my land need a perc test, a septic system and a well?
If it is off public sewer and water, usually yes. Before a county will issue a building permit for a home on septic and a well, the health department must issue the septic permit and the well permit (COMAR 26.04.02.03F), and the perc test is what shows whether, and where, the ground can take a septic system. Where the water table rises seasonally, the health department runs the perc test in the wet season, when the water table is highest; ask your county when its testing season is. New homes in the Critical Area need a nitrogen-removing (BAT) septic system; outside it a conventional system is allowed unless the county requires BAT. Your well is drilled by a Maryland-licensed well driller, who gets the permit from the county’s approving authority, and the water must pass lab tests before the well is used for drinking water. That is why we like to see a parcel before you close on it; site preparation covers the rest of the land work.
Do barndominium plans need an architect or an engineer in Maryland?
Not an architect’s seal for the house as a whole: Maryland lets a builder draw the plans for a single-family home it is building, and lets you draw plans for your own home, without an architect’s seal (Business Occupations and Professions Article §3-103). Our design team draws your custom plans. Steel-frame and pole barn homes usually fall outside the code’s standard framing tables, so the structure is designed by a licensed professional engineer working as a third party (IRC R301.1.3); the county decides what sealed drawings it needs, and we confirm that with the building department before we submit.
Can I put up a barndominium kit myself?
Yes, on your own land and for your own use. You can pull the permit yourself as an owner-builder when you build on your own land for your own use; the county will ask you to sign a statement saying so (Business Regulation Article §4.5-601). The home is still permitted and inspected like any other, and the sprinkler, septic and Critical Area rules still apply. Our barndominium kits page sets out what a kit includes and what it leaves to you.
Do you build additions, or a shop next to my existing house?
No. We build new barndominiums on land, the house and any shop under one new roof. The Home Improvement Commission licenses work on existing homes; building a brand-new house is outside it (Business Regulation Article §8-101). Additions, remodels, conversions and a garage or shop built beside an existing house fall on the other side of that line, and we do not offer them.
Who handles plumbing, electrical and HVAC?
Licensed trade contractors handle plumbing, electrical and HVAC. On a turnkey build we schedule that work as part of the project, so you deal with one point of contact from the first drawing to the final walkthrough rather than a chain of separate contractors.
How do I get started?
Start the survey. It asks where the land is, what you want to build, roughly how big, how you want to buy it (kit, shell or turnkey) and when. That is enough for us to come back with the questions that matter for your parcel. There is no charge for that conversation.
