fence post depth

I am building a picket in front of our house, fence will only be 3-3.5 feet tall. Does the 1/3 post rule apply here as far as setting the posts in concrete because that would mean i only need to dig them 1 foot underground. Thanks

The rule to me has always been 1/3 to 1/2. I'd shoot for 1 1/2 or preferably two feet. Keep in mind, the post does more than stabilize the fence it also supports it so you need the depth to handle the span, as well.

BTW, I believe parts of California have frost issues and if you're in that territory you need to be mindful of frost heaves.

While I agree with the 1/3 rule it's never a great idea to set a fence post less than 2' deep.

What I don't get is how u can install fence posts (like mine) with 4 inch concrete fastners using a post base like this above ground one: Simpson Strong-Tie 12-Gauge Black Powder-Coated E-Z Base-FPBB44 - The Home Depot

but if u want to bury the post u have to go pretty deep (fee deep), some of these codes don't make sense.... how can those small bolts will hold the post or not make wobble.
