Looking for a Place for a New Barndominium
Reader PATTI in MINNESOTA writes:
“My husband and I are knocking around the idea of doing a Barndominium.
We need a 4-5 car garage space and we can barely afford a traditional preloved home that has a 3-car garage which will require us to add another stall or two onto an already taxing home price!
I’m optimistic that we can pull off everything that’s needed and hopefully within the budget!
I’m doing the bulk of the research and found your site to be so packed with worthwhile information. I want to see what you’d be able to do for us to make this as seamless and headache free as possible?
I started looking for property and messaged the City Halls for the locations we want to see if they’d allow such a structure. Not sure how to handle the siding issue.
Inver Grove Heights, MN
Will consider it a single family home. Needs to meet setback, height and doesn’t exceed allowed impervious surface for the lot.
Exterior siding regulations require horizontal lap type siding or similar. Vertical siding like a pole barn is not acceptable material.
**** Is this even possible to meet this request or is there a way we can argue against it. Any knowledge you can offer would be so helpful****
Rosemount, MN
“The structure would function as a single family home, and therefore the exterior materials would need to be complementary to a residential structure (no metal siding, etc.). Additionally, the foundation would need to meet the building code requirements for frost footings. Also, the zoning code regulates the size of attached garages as follows: The footprint of an attached garage is a maximum of 1,000 square feet but can be increased up to a maximum of 1,500 square feet so long as the garage does not exceed 50 percent of the gross floor area of the principal building (garage and living area combined).”
Farmington, MN
*Considers this Agricultural that would need a minimum of 40 acres, what!!!
****Is this common and is there anything we can do to fight this so we get this under a single family home that we could put on a .25 acre plot?****”

Thank you for reaching out to us and for your kind words.

Planning Departments are an extension of a jurisdiction’s ruling body (city council, county commissioners) and have basically power of life and death. They can dictate footprints, heights, setbacks, type of cladding (roofing and/or siding), and even colors. They ARE limited to ordinances written by their ruling body, so if you do not hear an answer you like, ask for a copy of their written ordinance. If they cannot produce one, then it does not exist and can be disregarded.
One beauty of fully engineered post frame construction is a broad variety of siding and/or roofing options are readily available.
Inver Grove Heights – exterior siding is within their realm of control. At www ighmn.gov go to “City Code” in the left hand menu list and click on it. Scroll down to Chapter 15, then 10-15-17. B.2 gives your options with steel being none of them.
Rosemont – you do not have to pour a concrete foundation to meet Code requirements for frost. You will have to insulate the perimeter of your building to at least four feet below grade, not a big deal and can be done with rigid insulation (this insulation is typical for any type of structure). If you erect a 3000 square foot (sft) building, as much as 1500 sft can be garage.
Farmington – you threw them off at “pole barn house”. You are building a fully engineered custom designed wood frame home. This should be allowable anywhere zoned for single family residences. You may have exterior appearance and footprint issues once they have gotten this into their heads as being a SFR (Single Family Residence).
You will find as you get farther away from Minneapolis and into county rather than city controlled areas, things tend to become more property owner friendly. You also might consider South Dakota as an option, as our Planning and Zoning restrictions are few and far between.

We can create your ideal dream floor plan with this look. Every barndominium Hansen Pole Buildings provides is 100% custom designed to best meet the wants and needs of our clients and their loved ones. Please see #3 here to assist in determining needed spaces and approximate sizes, and to have professional floor plans and elevation drawings produced affordably.
Now we do have a fair number of clients using wet set brackets, keeping their building columns above ground (
Perhaps stick built construction’s biggest advantage is builders and tradespeople are very comfortable working in and around stick framing. All registered architects and most building inspectors are very familiar with stick framing. International Residential Code (IRC) provides a prescriptive ‘cook book’ to follow for adequate structural assembly, within certain limitations. These limitations include, but are not limited to, no story height of greater than 11 feet 7 inches (R301.3), no hurricane prone areas with a design wind speed of 130 mph or greater located south of Virginia, or 140 mph elsewhere (R301.2(5)B), and no ground snow loads over 70 psf (R301.2.3).
Once you have completed a business plan, find a lender who specializes in construction loans. To determine if you are qualified for a construction loan, your lender will need to verify your income, cash reserves, debt–to-income ratio and credit score and know you can provide necessary down payment. Down payment will be up to 30 percent of requested loan amount. Borrowers may use land equity as a substitute for a down payment. These requirements will allow your lender to see if you are able to repay the loan. Lenders are skeptical about providing construction loans to individuals. Providing a business plan for them to review will demonstrate you have researched and understand what is involved in constructing your barndominium.
Commonly (when addressed at all during construction) solutions to this problem have often involved creating a thermal break. A thermal break reduces contact between a structure’s warm interior air and cooler metal roofing, thereby reducing or eliminating overall condensation. Installing a reflective radiant barrier, often termed Vapor Barrier, involves laying rolls of faced ‘bubble wrap’ across your building’s purlins prior to roof steel installation. Ideal weather conditions are required for this as even a slight wind can make this a challenging or altogether impossible task. This can cause jobsite delays and may bring progress to a halt while a structure remains unprotected to weather. Even when ideal weather conditions are present, installing a reflective radiant barrier can be a very dangerous task, requiring builders to expose themselves to awkward material handling on a building’s bare roof framing. These risks and delays often generate additional costs for both owners and builders, but have often been necessary with reflective radiant barrier being the only relatively affordable option to prevent interior dripping.
Even with all of my years as a manager of owner of truss plants, 48 feet is as wide as I have participated in – although for our own personal shouse (Shop/house), we wish we would have gone 12 feet wider (no matter what size you build, it is never big enough). Your added investment, for floor itself, between having a myriad of internal columns, or clearspanning is roughly four dollars per square foot. For what it adds in downstairs usability by not having columns or walls to work around, it is worth every cent in my mind. Add to this it allows for all utilities to be hidden from view and they are a winning combination. As we are providing more barndominiums seemingly every day, we have many clients taking advantage of clearspan floor trusses and have never heard a regret from having done so!
DEAR RON: Most often (and most cost effective) is to effectively increase sidewall (eave height) and use a raised wood floor. To prevent rodent infiltration, clients have either used this:
DEAR POLE BARN GURU: Do you have an option to put the posts on a concrete wall or pylon? Where the posts don’t go in the ground. DREW in HAW RIVER
DEAR POLE BARN GURU: Not too sure if you’re able to help answer my question. I’m a homeowner looking to build a 24x24x10 pole barn with a 6/12 roof pitch. Looking to build my rafters for a more open ceiling instead of using trusses. My question is should I use 2×10 or 2×12 for rafters and do you recommend 24” or 48” spacing? I will have 12” over hangs. FRANK in MILFORD
1) Why would you want to use your own posts, when we have available and affordable stronger glulaminated columns than anywhere else in America?
DEAR POLE BARN GURU: I am getting ready to pour a concrete slab in my 24’x30′ pole barn. I calculated the thermal contraction along the 30′ length to be just over 1/8″. Would it be a good idea to install a foam sill sealer type material onto the inside of the grade boards to accommodate any thermal movement of the slab? DAVID in WESTFIELD
DEAR POLE BARN GURU: O great pole barn genius, what would I want to store an RV, also be at least a 2 car garage, and workshop, with a couple finished rooms for living quarters? What’s that beast called, and what should I budget for it low/high in KY? KIM in PAYNEVILLE 
DEAR BJ: Absolutely a bad idea. Pole barns “work” (e.g. stay standing) due to shear strength of steel sheeting (or OSB, plywood, etc., if used). When you place insulation boards between steel and framing, you are severely impacting ability of steel to carry those loads, as steel can shift slightly under wind loads. Eventually this will cause screw shank deformation (would take some very long screws), as well as slotting under screw gaskets, creating leaking (provided building doesn’t just fail first). If you really want to use XPS sheets, cut them to fit snugly between purlins and girts, taping all edges to achieve a tight seal.
DEAR POLE BARN GURU: I would like to think of something for my 2 boys and I. One story 3 bed 2 bath. Living room dining room kitchen, laundry room with walk in closets. About what size would you recommend? SHANNON in KIPTON
DEAR MICHAEL: A caution – if your shed roof ties in at any height other than exactly at eave, or is not at same slope as existing roof, you have a snow slide off/drift load to contend with and are best to engage an engineer to account for this extra loading. An exception would be if you have a snow retention system on your existing roof. Assuming above is not an issue, please read on. As I do not know your loads, you can fill in blanks in this formula to find out: (roof live load + roof dead load) x spacing (in your instance 96″) x span in feet squared (14′ squared for you). Divide this answer by: 8 x Rafter Section Modulus x Fb (fiberstress in bending of lumber proposed to be used) x 1.15 (duration of load for snow) If your result is 1.0 or less, then you are golden. Section Modulus is depth of member squared x width of member divided by 6 Example : 2×12 = 11.25″^2 x 1.5″ / 6 = 31.64 Fb for #2 grade Southern Pine will be 2×8 = 925; 2×10 = 800; 2×12 = 750
DEAR GLEN: Maybe, provided your existing building footings are adequate to support weight you will be adding. Easiest and safest way is to set a row of columns directly alongside existing building wall, so you can treat new structure as being self-supporting. You will not have to pour a foundation, you can auger holes, place UC-4B pressure treated columns in holes, then backfill bottom 16-18″ with premix concrete to create a bottom collar. If your new lean-to has a pitch break, or is lower than main roof on high side, you do need to account for weight of slide off/drifting snow onto it. This can be avoided, by installing a snow retention system on your existing roof.
DEAR POLE BARN GURU: What is the difference between a pole barn home and a barndominium? SHARON in WESTCLIFFE
DEAR TERRI: Fully engineered post frame, modest tastes, totally DIY, move in ready, budget roughly $70-80 per sft of floor space for living areas, $35 for all others. Does not include land, site prep, utilities, permits. Your new Hansen Pole Building kit is designed for an average physically capable person, who can and will read and follow instructions, to successfully construct your own beautiful building shell, without extensive prior construction knowledge (and most of our clients do DIY – saving tens of thousands of dollars). We’ve had clients ranging from septuagenarians to fathers bonding with their teenage daughters erect their own buildings, so chances are – you can as well! Your new building investment includes full multi-page 24” x 36” structural blueprints detailing location and attachment of every piece (as well as suitable for obtaining Building Permits), our industry’s best, fully illustrated, step-by-step installation manual, and unlimited technical support from people who have actually built post frame buildings. Even better – it includes our industry leading Limited Lifetime Structural warranty! If hiring it done turnkey, expect to pay two to three times as much. This is why so many of our clients do some or all work themselves.
DEAR MATT: While it would certainly make for a larger screw target, when wall steel panels are predrilled, keeping screw lines straight and hitting commercial girts really is not an issue. Outside of extra materials and more labor, there are a couple of areas of possible concern: 6×6 columns vary in dimension. With a 2×8 commercial girt, extending 1-1/2″ outside of columns, a 6×6 up to 5-3/4″ can easily be hidden. If your idea is to use a 2×6 commercial girt, behind a 2×4 external girt, if columns run over dimension they will leave an uneven surface for internal finish. Of course, should you mount a 2×4 external girt above or below a 2×8 commercial girt (forming an “L”), then this concern goes away. Your other possible challenge would be in connecting these two members. Greatest force on wall girts is outward suction, so your 2×4 external girt and 2×6 bookshelf commercial girt will need to be adequately connected so as to not have external girt pull away and fail. This connection should be analyzed by an engineer.
Skillion roofs have a single sloped flat surface. Other names for this style include lean-to, mono-pitched or mono-slope, or shed roof. They are popular for minimal and contemporary-style buildings.
If it was my own roof – I would remove all fiberglass roof plane insulation, increase thickness of closed cell spray foam to at least two inches, then fill balance of 2×8 cavity with either open cell spray foam or rock wool batts (rock wool is not affected by moisture and does not lose R value during cold temperatures).
When considering energy costs, there is a false preconception solar panels are extremely expensive and cost-ineffective. However,

There are jurisdictions sadly attempting to prevent ‘pole barn houses’ in their neighborhoods. Scenarios usually go something like this – a potential homeowner inquires to their local building permit issuing authority and asks, “Can I build a pole barn home here”? Too often (in my opinion one time is too often) they are told flatly no. Most of these who do move forward, automatically default to an easy route and stick frame.
When I first began selling pole barn kits in Oregon, back in 1980, they were almost universally no permit required farm buildings. As our service area expanded into states such as California and Nevada, engineering was required in most instances, however there was never a concern about a pole building not being approved for use in any jurisdiction.
We have also added an in-house Barndominium Floor Plan Specialist to our team. This service creates for you your ideal dream floor plan, as every barndominium Hansen Pole Buildings provides is 100% custom designed to best meet our clients and their loved ones wants and needs. Professional floor plans and elevation drawings can be yours for as little as $695 and should you happen to move forward and order your barndominium from us, we offer a credit back against your investment of $695 – effectively making this a free service for a one story barndominium!

“Greetings – I’ve got a pole barn style home that’s about 2.5 years old and I’m having moisture issues in the attic. Hoping I can talk with someone to get a consult or second opinion to resolve as quickly as possible. Let me know if it is something you can connect on. Attached is an image from the attic where you can see moisture on the underside of the metal roof. It freezes at night and then during the day when the sun is out, it melts and drips into the attic insulation. 


Easiest solve is to have two inches of closed cell spray foam applied to underside of roof purlins. Any other solutions will take removal of roof steel panels, adding a thermal break, and then reinstalling roofing.

Closed cell spray foam applied directly to steel roofing and siding can be a great product for controlling condensation, achieving an air tight barndominium and at R-7 per inch is a great insulation solution. So good, I strongly encourage its use, especially for those buildings in Climate Zones one and two (deep South).

Syracuse, Nebraska was laid out in 1869 when it was certain railroads would be extended to it. With a population of roughly 2000, Syracuse is pretty well smack dab centered in Nebraska, in Otoe county.
Most post frame buildings have shells erected then slab poured, so this should not be an issue. A pressure preservative treated splash plank should be in place around this building’s perimeter. It will become forms for your slab. Snap a chalk line on the inside of splash planks up 3-1/2″ from bottom, this will be top of your slab. 




Your new building will be designed for an average physically capable person who can and will read instructions to successfully construct your own beautiful buildings (and many of our clients do DIY).

Fully engineered post-frame buildings (pole barn houses in this article) can be entirely Code conforming structural systems. There may be a thought pole barn houses are ‘unsightly’ to some, due to being most often sided with roll formed steel panels. Post frame buildings can have any roofing and/or siding materials found on other structural systems, such as stud wall (stick frame). Sidings can include wood, vinyl, masonry, stucco, the possibilities being endless. To place a restriction only upon one structural system, rather than all systems universally could be seen as prejudicial, as well as a restriction of free trade and Interstate Commerce.
“Please be aware that the Land Development Code and adopted Building Codes 
Fully engineered post frame homes and barndominiums (barn homes) are beautiful because they only limit your heights under Building Codes to three stories and a 40 foot wall height (add another story and 10 feet for having fire suppression sprinklers – a good idea anyhow). My lovely bride and I live in a post frame home with a 44 foot overall height (and a cupola on top of it). Although this article is written for two story homes it may prove helpful:

#3 Have professional floor plans

Our particular building site had significant amounts of clay and we chose to excavate it out (over excavate) and replace with compactable fill. Our site is also built up, so any rain or snowmelt runs away from our home. After 15 years of service we have only minimal hairline cracks in our slab on grade – even though we have been through winters of seven feet of frost! Our building has no perimeter grade beams and our columns are embedded in concrete six feet below grade.
At Hansen Pole Buildings, we are literally “All About the Building” and we strive to provide “The Ultimate Post Frame Building Experience™”. Every single one of our fully engineered post frame buildings is custom designed to best fit our client’s wants and needs. Rarely will we be least expensive, however we will always provide a best value solution.

Your fully engineered post frame home is 100% Building Code Compliant and most typically has pressure preservative treated columns embedded in ground with both concrete footings and bottom collars. Alternatively your home can be mounted to steel brackets set in concrete piers.

The topic was brought up at the Aug. 6 meeting after Szokola reported he had seen more than one house come through requesting permits in which the house didn’t quite fit with what a typical house in the area might look like.
Now let them work. Don’t try to supervise every blow of a hammer or placement of every stud. These guys are professionals and they know more about their trades than you do, and probably, if they came to you well recommended, they take pride in their work. Let them do it.

Another thing we did in building our cabinets was to put the dishwashers on a wood pedestal by the seating for the bar area. Dishes are easier to add or remove at that height for both Mike and myself. I’m in a tall power wheelchair so access to appliances is paramount for me.
The aisleways between an island or peninsula should also be plenty wide for two people working in a kitchen at the same time. Again, without knowing we’d need more width between counters and appliances, we designed the kitchen with 52″ between the kitchen sink and island. We used a full 5′ between the island and fridge/freezer area due to the doors possibly being open when the other one of want’s to get by. Both allow Mike and I to be working in the kitchen at the same time and he can zip around my chair if need be.
Have lots of children? Rather than having all sorts of very small bedrooms so each child has their own space – institute room sharing, incorporating larger bedrooms with walk in closets. While lots of small bedrooms may work well for your lifestyle, it is a personal design choice not appealing to most potential buyers.
Curb appeal describes a potential buyer’s feeling of a home as he or she approaches it, based on how it looks from outside. In recent years, this initial impression has extended beyond just physical and into a realm of virtual reality. How a home looks online can also greatly influence a buyer’s interest — in fact, in today’s highly competitive market, this is where curb appeal really begins.


Seemingly millions of canned house plans are available (for a small to large fee) across a plethora of internet websites. 99.9% of these plans have a similar problem – they were designed for a flat lot in suburbia! Yep, they look stunning on a website. Considering spending your hard earned money on one thinking you will save money by using cheap house plans? This would be an equivalent to everyone buying 34 inch waist 36 inch inseam Levi’s. They fit me just fine, but what if you are not 6’5”? Or maybe you do not even like Levi’s?
“We would like to build a post frame home but I would like to have a whole house fan to cut down on cooling costs. Most barndos we see under construction use spray foam insulation directly against the metal roofing/ siding which would prevent the use of a whole house fan. You talk about blown in insulation and roof venting which sounds similar to stick built homes. So is it safe to assume that your designs would allow us to install a whole house fan in the attic space with adequate venting? I fondly recall the ancient airplane engine attic fans 3 or 4 ft wide from years ago and was pleasantly surprised to see the new ones drastically reduced in size and volume. What is your opinion on this?”



I know that the costs for SIPs mostly comes from the manufacturer having to essentially custom make each piece. In this application the SIP panels could be made as rectangles that are as wide as your center to center post distance and as tall as is convenient. Any angled pieces for gable ends and any fenestrations could be cut on site, reducing SIP manufacturing costs. The SIPs also would likely not have to have much dimensional lumber built into the SIP because it is just holding up itself and windows, not the whole building thereby drastically reducing your thermal bridging. You could also foam seal between the SIP panels to provide air sealing (which I believe is standard for SIPs anyway.)

In most parts of our country (and probably most other developed countries), it will be a necessity to acquire a building permit in order to construct a new barndominium, shouse (shop/house) or post frame home. Easiest way to find out is to contact your local authorities to find out if indeed this is your case.
A few years ago, our oldest son Jake needed a new post frame garage at their home near Knoxville, Tennessee. His mom convinced him this plan would be so much better with a mother-in-law apartment upstairs. We used 4×2 (2x4s turned flat) floor trusses to span a 24 foot width!

For those who have been following along, I have covered preliminary steps leading to actually designing a functional and affordable floor plan.
Thank you for your interest in a new Hansen Pole Building. We have wholesale relationships all across America and will ship bulkiest items, in most cases lumber and trusses, from your locale – freight costs will be no more for you, than they would be to any other location.
Yes we can provide plans with a third-party engineered design for bracket set columns, as well as brackets.
Home sizes can be split up into three groups – small (under 2000 square feet), medium (2000-2999 square feet) and large (over 3000 square feet). In discussions about possible rooms and sizes average square footage (sft) for each size will be indicated.
