Today’s “Ask the Guru” addresses reader questions about Perma Column Cast Concrete pole bottoms) that seems to be the ticket to eliminate any concern about rot, a list of what is included in a Hansen Building Kit, and if Hansen designs are classified as single family dwellings.
DEAR POLE BARN GURU: As a prospective customer, doing as much research and educating myself your site and information has been a wonderful tool. Through my educational journey the most confusing area is with post construction being set in concrete. Your blog has answered many questions and worked to dispel myths about rotting wood. But, there is a product or system (Perma Column Cast Concrete pole bottoms) that seems to be the ticket to eliminate any concern about rot, Valid or not. What are your thoughts on this approach? Any insights are very much appreciated. BRIAN in POULSBO
DEAR BRIAN: Thank you for your kind words. Having provided and/or built close to 10,000 post frame buildings in Washington state since 1980, I have yet to receive a report of a properly pressure preservative treated column decaying prematurely. However, this does not mean you could not be a first. With this said, there is an easier and less costly option than precast PermaColumns. I have expounded upon it here: https://www.hansenpolebuildings.com/2025/10/perma-column-2/

DEAR POLE BARN GURU: Are any of your barndominiums classified as a single family dwellings? JOHN in EAST CANTON
DEAR JOHN: Most of our barndominiums are single family dwellings, although we can provide multi-family and even as apartment buildings. Limitations being 40-foot tall sidewalls and three stories.
DEAR BILL: Your idea is totally possible. I have done it myself. In my case I had 12 feet of grade change across my building’s 40 foot width. I used ICFs full height on one sidewall and stepping down across rear endwall. Columns on these two walls were mounted using wet set brackets, other two walls had embedded columns. This process could also be used with poured concrete or block walls. We have also developed a system to use columns placed in a permanent wood foundation.
DEAR POLE BARN GURU:
DEAR KELLY: Pressure preservative treated wood standards can be confusing even for lumber dealers, professional builders and building inspectors. For structural building columns, all end tags should have UC-4B marked on them. UC-4B is for “Heavy Duty” use. This American Wood Preservers Association infographic might prove helpful to understanding proper uses for pressure preservative treated wood:
Reader MATT in PIERRE writes: “Is there any possibility that the ICC will adopt an appendix related to pole-frame buildings. We require engineering in our local jurisdiction at this time and it would be much simpler for customers who want to build a pole-barn if there was a way to construct these buildings without engineering. They do have an appendix for straw bale houses, of which I have seen exactly 0. Thank you!” 
DEAR JASON & ERIN: Your plans did not arrive as an attachment, so I am unable to speak to them. If your concern is with properly pressure preservative columns prematurely decaying when embedded in ground, then Permacolumn Sturdi-Wall Plus brackets are indeed your best design solution. Unlike other, cheaper, brackets, these actually will resist moment (bending) forces and have ICC-ESR approvals as being Building Code conforming. For extended reading on Sturdi-Wall Plus brackets:
DEAR POLE BARN GURU: How tall would a barn have to be to accommodate horses on the bottom and eventually a 2 bed 2 bath apartment in the loft? JUSTINE in LITTLETON 
DEAR TAMI: Provided footings beneath your CMU wall are adequate in dimension, probably. In areas of your existing wall where ICC ESR approved engineered wet-set brackets for columns will be placed, existing blocks will need to be removed and replaced, so brackets can be properly poured into wall.
DEAR POLE BARN GURU: I see a lot of discussion about using the Sturdi-wall wet set bracket when using a concrete pier for posts. I was wondering if the Simpson CB (column base) is used in post frame construction? From their documentation it looks like that is what it was designed for. RON in HILO
DEAR POLE BARN GURU: I have a barn that doesn’t have soffit vents but it does have a ridge vent. I installed reflective insulation which seems to have dropped the temperature quite a bit. I also have a gable powered fan that does 2000 CFM. However it is about 8 to 10 feet lower than the ridge vent. Are these two things fighting each other do you think or should I take a pipe and vent it up to my ridge vent and to my fan to take the hot air out from the top or should I turn my gable fan off completely.
DEAR LOUIE: Drives me absolutely bonkers when providers or builders make no true efforts to advise customers on perils of condensation and how to prevent it. So easily, and inexpensively, done at time of construction.
DEAR DENNIS: Properly pressure preservative treated columns, embedded in ground are unlikely to decay within lifetimes of anyone alive on our planet today
