post frame building code requirements?

[StevenMorgan]

New member with a dream to build a 26x52 post frame garage. I am a 25 year old aircraft design engineer, and have been drawing up floorplans and pricing kits for my shop/garage. I will be restoring and building airplanes in one half of the space, and parking my truck and my wifes suv in the other half.

Here is where the questions arise. I have a narrow lot to build on, and need to place the two 12' garage doors on the eave wall. The overhead doors need to be 12' so I can easily and consistently "swing" my truck into the garage (the driveway is parallel to the long eave wall)

My concern is post spacing and the header required to span at least 12' if not more like 15'. I can easily overbuild it with several 2x12 laminated together or LVL beam, but do I need this to pass an inspection? Do I need stamped engineering drawings to use a wide post spacing and large header?

I know most areas require stamped truss plans and I will get those... I am planning 10/12 attic trusses spaced 2', but I am concerned about the walls and door headers... any recommendations?

Since codes very from place to place, you should visit your local bldg code officials office or zoning office. They should be able to point you in the right direction.

most likely will not require engineered drawings for a wood framed construction header, lumber yards size these things all the time and the towns have no issue with it. regarding your truss plans i hope you mean the truss company is stamping them and you arent paying an outside engineer to stamp them

Since I had to have a permit to build I worked with a local pole building supplier to design and put together a 'kit'. Part of the deal I required them to provide the building permit so that they would have to deal with the county on engineering drawings and such. I received the permit and engineering drawings BEFORE I accepted and paid for the materials. Worked for me.

This sounds like what I will eventually be doing... I am in the preliminary "dreaming" phase and have yet to call the local pole barn company. I just put my info in a couple different pole barn kit websites...

I did call a local truss shop who would provide stamped drawings with their trusses for a reasonable price. I am just trying to see how much money I am going to have to allocate for this.

I had to have stamped engineer drawings for my trusses, and the company who built mine provided them.

I'm building a garage with three 12x12 doors, got the garage/pole barn from Menards and it has LVL header boards on the inside and outside of the wall with 2,2x12 boards on the inside of those so it's pretty much solid. good luck.
