Does anybody know how far O.C. anchor bolts are supposed to be? It's been a while since I've done any framing, and I've got a garage to build next month. BTW, I'm in CT. Thanks

We start 6" in from the corner and then 24" O.C.

Or we use Titan bolts (They are like a big Tapcon), the same layout but can be put in after the concrete is cured.

But I am in Florida so it may not be applicable to where you are.

As I recall:
IRC 2003 6' OC
IRC 2006 4' OC
I have always remembered doing it at 4 but that has been awhile

Always check with your local building dept

depends on where you are in CT. Local codes supersede national so check with your local building department. Thickness also varies. For instance nassau/suffolk counties in new york have been hurricane zones for several years now - our anchor bolts are 5/8". 6"-12" off corner and then spaced depending on locality. Depends on design wind load and height of building. Anywhere from two to four feet on center.

Pretty sure here in Ohio, 12 inches in from the corners, then every 6 feet. Seems its different everywhere so hows about telling us where you are.

12" in from corner then 4' oc is standard. Then the engineers get involved. I did a 5 story condo in Ocean Shores, WA built to 130+ MPH wind loads. The anchor bolts were 5/8" at 10" oc for the entire north side wall. It was insane.

Then you add hold downs for all openings, etc.

24 from corner and 6 ft o.c is the standard around these parts
