So now you've gone thru the "cosmetics" Kitchen remodel/bath remodel/opening up the floor (and don't forget the cost of the "supporting beams") , new flooring, paint, smooth ceilings; don't neglect the structural aspect and exterior - electrical upgrade?

Dustin Beam Hey there!

And let's just say the laser machine in the corner isnt my idea.

The joists are then hung from this perimeter by inserting them perpendicular between the outside perimeter and the field laminated 4x12 ((2, 2x12s lag bolted together)intermediary cross beams that are pinned to #4 rebar that I cast into smaller, interior support piers.

Spaced lumber sheathing is not allowed in Seismic Design Category D2.TABLE R803.1 MINIMUM THICKNESS OF LUMBER ROOF SHEATHING RAFTER OR BEAM SPACING (inches) MINIMUM NET THICKNESS (inches) 24 5/8 48a 11/2 T & G 60b 72c For SI: 1 inch = 25.4 mm.

@Tony Tran   would that be sharks with  laser beams  :)

Concrete that is to support a load will have a footer or beam that extends down into the earth up to a few feet.

There are wood beams on the ceiling in the living we did the same with.

Look at the rafters to see if they are pulling away from the ridge beam or is they are bowed or cracked.For the electrical, pull the panel cover and see if you have corroded connections, aluminum wire connections, wire sizes correct based on the breakers that they are attached to, ground wires visible, signs of burn marks, etc.For the plumbing, run everything at once.

Ceiling is 7' to the bottom of the exposed beams.
