I am constructing a small 4' * 7' freestanding back door stoop and
would like some feedback on beam sizing. Will the 4*6 beams span the
7' with no problem. Joist will be 16"oc. And the stoop will be
lightly used.

I'm using 2 4*6 beams attached to 4*4 posts set on concrete footings
(16*16*8). The beams are parallel to the side of the house. The first
beam is about 19 inches from the foundation wall. I plan on
cantilevering 2*6 joists on that side of the porch so that I can get
the deck boards up against the house. The beam nearest the house will
be lower than the other so that the joists rest on top of it but are
flush with the far beam.

I plan on using (2) 6" lag screws per post/beam connection. The beams
will be attached to the sides of the posts and the posts will extend up
to build a railing. I had planned to add in some minimal y-bracing if
needed.

Feedback please. This stoop will step down to a larger patio/deck when
all is said and done. If only money wasn't an issue :) I'd do it all
now.

Why not connect the deck to the house with a ledger
board?

Are you sure that the footings for the first posts will
not hit the footing for the house?

Use metal hurricane straps to attach the first beam to
the joists resting on top.

How do you know the size of your footings? Got
permit.....talked to inspector? This is hard to re -do
if it is not to code.

Peace

Nice AsciiCad Drawing :o)

umm make your life a little easier

use a 6" post
and Two 2x8s nailed together to make your beams
Use a little glue too

Then to install your posts
use a circular saw to cut yourself a ledge on the top of the post
Basicaly you are just going to cut half the thickness
of the 6x6 post away so you can rest the beam on it and use
Hot Dipped cariage bolts with nuts and lock washers

As for the footing I think maybe 2x2x2 foot block of concrete is fine
with a metal post holder to attach the post to the concrete

use 2x8 for your floor joists


However every thing you want to do is probably just on the edge of
specs for lumber sizes

Find a Span Chart

Not sure of your sizes, does 4*6 mean a doubled 2" x 6" x 7' ?

How high off the ground is the stoop?

Is the future patio/deck doing to be at ground level?

Steve.

This will probably help.

By the way, where are you? Frost line will determine how deep the posts
need to be.
