Information on Codes and Shouses

Information on Codes and Shouses

I have to admit it was rather flattering to have Southwest Iowa’s Planning Council reach out to me regarding information on Codes and Shouses recently.

“Hello. My name is Ashley and I’m a community development specialist with Southwest Iowa Planning Council out of Atlantic, IA. I am currently working on some Zoning and Building codes for smaller towns and they want to include zones and/or building codes for shouses. Since this is relatively new to this area, within city limits at least, I was curious what issues your company has come across regarding codes and if you had any sample codes from communities that you would be willing to share with me?”

Mike the Pole Barn Guru responds:

Thank you for reaching out to us. We have provided hundreds of post frame shouses and barndominiums in nearly every state. Good news for you (and these jurisdictions) is this project will involve very little extra efforts beyond what is currently in place.

Use of terms such as “pole barn”, “pole building” or “post frame” home, barndominium, shouse or shop/house oftentimes cause permitting waters to become clouded – yet they need not be.

From a Zoning/Planning standpoint – shouses (I will use this as an all encompassing term) should be treated no differently than any other code compliant structural system. Any existing requirements for setbacks, footprint requirements, heights, living area to garage/shop ratios, siding and/or roofing materials, color restrictions, etc., should remain the same as currently adopted. What is important is to not place restrictions upon shouses not existing for other dwellings, as this could end up leading to costly and protracted legal battles.

Currently adopted Building Codes (IRC, IBC, IECC) do not have to be amended for shouses.

In “Effective Use of the International Residential Code”:

Paragraph 4:

“It is important to understand that the IRC contains coverage for what is conventional and common in residential construction practice. While the IRC will provide all of the needed coverage for most residential construction, it might not address construction practices and systems that are atypical or rarely encountered in the industry.”

IRC R301.1.3 Engineered design.

“When a building of otherwise conventional construction contains structural elements exceeding the limits of Section R301 or otherwise not conforming to this code, these elements shall be designed in accordance with accepted engineering practice. The extent of such design need only demonstrate compliance of nonconventional elements with other applicable provisions and shall be compatible with the performance of the conventional framed system. Engineered design in accordance with the International Building Code is permitted for all buildings and structures, and parts thereof, included in the scope of this code.”

In summary (and in my humble opinion), any shouse outside of IRC prescriptive requirements, should be designed and have structural plans signed by a Registered Design Professional (architect or engineer) to meet or exceed jurisdictional climactic conditions.

Please feel free (or direct any jurisdiction) to reach out to me directly with any questions or concerns.

Dry Set Brackets, Snow Loads, and Winch Boxes

The Pole Barn Guru continues to be inundated with reader questions, so we will be adding some mid-week PBG responses. First off is a questions about attaching posts to a square footing with dry set brackets, whether or not a Hansen Building can withstand a 40lb snow load (they most certainly can), and the use of winch boxes to raise trusses.

DEAR POLE BARN GURU: Can poles or square posts be attached to cement footings? 30 years ago we started working on a post and beam barn, cutting traditional joints, etc. Well that project was not completed you can guess why. Now we still have the footings that were going to have sills attached and the timber frame joined to that. My other half thinks we can essentially build a pole barn by bolting posts to footings. I have my doubts because as I understand it part of the stability of the pole barn depends on the integrity of the pole and its depth in the ground.

Thanks, MIMI in CATHARPIN

DEAR MIMI: There are dry set brackets designed for attaching post frame building columns to existing concrete, however our third party engineers will no longer certify them for use as they will not resist moment (bending) loads.

DEAR POLE BARN GURU: Do your buildings support a snow load of 60+ lbs per square foot? JARED in BONE

DEAR JARED: Every Hansen Pole Building is designed and engineered specifically for loading (wind, snow and seismic) conditions at your particular site. We have provided buildings with ground snow loads in excess of 400 psf (pounds per square foot), so your snow load should not be a difficulty. A Hansen Pole Buildings’ Designer will be reaching out to you for further information and to assist you with your new post frame building.

 

DEAR POLE BARN GURU: I am working with Mindi on my quote. I found info on using hand crank winches to raise preconstructed sections of the trusses and purlins. In the different articles, the construct a steel box that the winch is attached to and the box/winch is placed on the top of the poles. If I use wet set brackets, how much extra length is provided on the column? Would I be able to use the winch method with columns bolted into brackets? If I have a 24 ft span and 3:12 pitch, about how much would one truss weigh?
Thanks, LEE in HUNTSVILLE

DEAR LEE: Kudos for you to look to using winch boxes! Your savings in time (and safety) will more than pay to build a set of boxes. With wet set brackets you might want to have Mindi add two feet in length to your truss supporting columns, otherwise you will end up very tight for column above trusses. Cranking up trusses with purlins attached works equally well with either embedded or wet set brackets. Two pairs of trusses and all purlins for a bay will weigh somewhere under a thousand pounds.
