Occupancy, a Single-Slope Residence, and Lean-to Addition

This week the Pole Barn Guru take care of reader questions about getting an occupancy permit in Victor ID, the size and scope of building a single-slope with a loft, and the addition of a lean-to to an existing structure.

DEAR POLE BARN GURU: I follow your posts and have seen some who question if a pole building can be built as a home and get an occupancy permit. I have some property in Victor Idaho, Teton County Idaho building department. My question is: Can I build a small (about 1200 square feet) building in Teton County Idaho and get an occupancy permit to live in it? Thanks! AL in SURPRISE

DEAR AL: My first experience with Teton County was nearly 30 years ago – when, as a General Contractor, we built a post frame building for Driggs Plumbing. Fully engineered post frame buildings are 100% Code conforming structures and when designed appropriately for Risk Category II and a R-3 (residential) occupancy they make for excellent homes. I have read through Teton County’s Building Department information online and see no minimum footprint requirements for homes, however you would be best served to give a call to Teton County’s Planning and Zoning Department at 208.354.2593. https://www.hansenpolebuildings.com/2020/01/your-barndominiums-planning-department/

 

DEAR POLE BARN GURU: Hello. We are in the planning stages of designing our home and are thinking of building a 40×60, single slope home with a loft on the tall side. Have you ever designed anything like this? I am having a hard time figuring out what height walls I would need and what pitch roof in order to accommodate a loft. I am thinking that i would like 10’ ceilings and 8’ ceiling for the loft, but worried that being vaulted, I will lose usable room space fast. Please let me know if you can help. Thanks! NATE in BIXBY

DEAR NATE: For sake of discussion, let’s work from a 12′ loft width. Allowing for your requested ceiling heights at low side of loft, and thickness of floor and roof system, a 22′ height is not unrealistic at this point. With a 3/12 roof slope (typically a minimum to prevent voiding roof steel paint warranty) your eave heights would be 25′ down to 15′.

 

DEAR POLE BARN GURU: How to tie a self-supporting lean-to onto my existing pole building? Ham Lake city inspector said my existing pole building footings don’t support the added weight of a lean-to and therefore need posts on the high side of the lean-to. Pole Building is 30×64. Lean-to is 19×64. Ham Lake inspector says you don’t need to tie the buildings together other than the lean-to roof tucked underneath the existing roof. The 9 posts on the high side lean-to will be 1′ away from the existing 9 post on the Pole Building. I want to tie these two posts together. I’m thinking of cutting a hole in the siding and nailing a 2×6 onto each post at the top somewhere. Do you have any suggestions? Thanks. KEITH in HAM LAKE

DEAR KEITH: Your Building Inspector is absolutely correct. I see far too many cases similar to yours where a lean-to is added onto an existing building and due to inadequate footings results in an up-and-down roofline. Not certain why you would want to go through efforts of trying to connect those columns, and any meaningful connection could result in loads being inadvertently transferred between buildings. To me, it sounds like more work and efforts than it could ever be worth. We had this very same situation when we added a 30′ x 96′ lean-to to our 96′ x 96′ warehouse. We did not tie columns together and have never experienced any sort of negative challenges from it.

 

 

Residential Building, I-Joist Purlins, and Post Proximity

This week the Pole Barn Guru answers reader questions about whether or not Hansen can provide a residential building kit in their area, if Mike advises the use of I-Joists as purlins, and post proximity– how close can two posts be to each other?

DEAR POLE BARN GURU: I’ve read your reasonings and seen your snippets of engineering drawings that spec 2x purlins hanging between trusses. I’m wondering if now that I-joists are becoming so popular for residential use, if you’ve ever tried to use them as purlins. A 9.5″ I-joist would allow for 8″ of mixed closed and open cell spray foam, and a bottom flange of 1.5″ for light fixtures, wiring, etc. And I think I-joists would be lighter than 2x10s (and in this economy maybe even cost less!).
Thank you,
Thinking About A Hansen Handsome Barndominium, Or more accurately, GUY in JOHNSON CITY

DEAR GUY: I’ve used engineered floor trusses for roof purlins, but never I-joists. While I do not personally like them for floors (I find them bouncy), they do work as a replacement for dimensional lumber joists and rafters. I-joists are fairly strong when loads are applied directly perpendicular, however they are not strong in weak axis bending (e.g. loads applied when they are rotated from vertical). While they might work as roof purlins, it would take a significant amount of blocking and/or bracing plus some healthy engineering analysis in order to design a system to restrain them from buckling.

 

DEAR POLE BARN GURU: How close can the posts actually be to each other? Are there physical limitations to drilling two holes 12 inches apart? The reason I ask is I want to build a garage that mirrors the garage on my house, and the first 9 foot wide door is 25 inches from a corner and the spacing between the two doors is only 15 inches, rough opening to rough opening. Does one just dig a hole large enough for both posts? Or should two holes be drilled that overlap? SCOTT in BROOKSTON


DEAR SCOTT:
Two posts can actually be in direct contact with each other, if necessary to support things like door openings. When two columns are close together, it is usually easiest to end up digging what resembles a trench, rather than a larger diameter hole (effectively drilling two overlapping holes).
