Hello,

I removed a load bearing wall and installed a header made from 2 2 x 10's. The new opening is 8 foot wide. This is on the fisrt floor of my 2 story home. I believe the new header is supporting part of the roof load.

I was wondering if there is a "rule of thumb" as to how many jack studs are needed on each side to support the header.

I currently have 3 2x4's on each side supporting the header and I would like to remove as many of them as possible.

Is one 2x4 jack stud enough on each side?

Thanks!

Little confused on how to read those charts.

The bearning wall is on the first floor and right under where the second floor joists overlapped or extended. For example, there is a joist running from the fron tof the house to where the wall was, this joist ends about 3 inches past the bearing wall and another joist continues to the back of the house and is nailed to the side of the original joist. Make sense?

Above is a bedroom and above the bedroom is the attic. The roof is a truss roof where the peak is parallel to the bearing wall.

Are the 2 2x10's enough?

If it is enough, how many jack studs for the 8 foot span?

If not enough, can you tell me what I need, based off those charts?


Thanks.

The table shows; 20' building width span (running with the trusses) = 2-2x12's = 8'1" span #2 grade lumber.

28' building width = 2-2x12's = NO (requires 3-2x12 + 8'10" #2 lumber)
Two jacks each side, solid blocking in floor below to beam or pier. You should get a permit for this, for the paper trail for your Homeowners Insurance carrier and when you go to sell the house.

Is it too late to get a permit once the project is started?

Also, there is a header installed already, by the builder when the house was already built that supports a span of 12 feet, it is 3 2x12's, accoring to the chart, is this not correct?

I would get a permit even though you have started. Go to your building department and speak with them. You will not be the first to have done this.

If I were buying your house and see the modifications I would be asking the permit questions. Sure is easy and better to answer yes in the future rather than having to dance or deal with it way after the fact.

"lso, there is a header installed already, by the builder when the house was already built that supports a span of 12 feet, it is 3 2x12's, accoring to the chart, is this not correct?" -------- No, it is over-spanned for the loads.

I say again, get a permit----- because you are dealing with potentially thousands of pounds unsafely carried above you.

You already removed the wall added a header and jacks--- now you want to remove some jacks to make a weak header even weaker........ Hence my first reason to get a permit might have prompted you more than loads involved....

If Joe C. (previous post) makes it unanimous, will you get a permit?

In case you don't know what Chris said about point loads are, the weight carried by whatever jacks/header you use, needs to be carried down to the foundation.
The floor alone cannot carry this weight.
