Deck Beam Overhang

Hello,

I just took apart my old deck but kept the ledger and the posts for what i am hoping will be a bigger deck.

the original deck had beams going west-east from the ledger to the post. The length of each beam was 6.5' and each post is 5' apart.

The floor joists were sitting on top of the beams going north-south.

I wish to extend the beams from the ledger to 13' feet ideally (would go to 12' if 13' not possible) without having to put anymore posts.

Is that possible or the overhang is too big? is there another way to add support without having to put concrete posts as they have to go 4 feet deep where i live.

Thanks,
Anton.

Standard rules say you may not cantilever (overhang) a beam more then 24" but local rules can overrule that rule.

Original beams were 6 1/2' long and space between ledger to post was 5'.

You want to extend the beams to 12' or 13' with the same 5' post space?

Allowable overhang is 1/4 the span so original deck was good, you will need to move the posts or add a second set.

Do some searching on this site, somebody posted a link to a good set of deck design instructions
