Structural Framing
The house stops being a drawing. Plumb, level, square, dry.
Typical duration: 3–6 weeks

Sill Plates, Wall Framing & Layout
Plate layout, wall framing, openings, and blocking that every later trade depends on.
Framing
Prerequisites & handoff
- Slab cured and swept
- Anchor bolts verified
- Approved plans on site
Critical measurements & tolerances
- Pressure-treated sill plate with sill sealer / termite barrier on all concrete contact
- Studs 16" on center standard, 24" allowed on some non-bearing and advanced-framing walls
- Walls plumb within 1/4" over 8' and straight within 1/4" in 10'
- Rough openings: standard interior door RO = door width + 2", height + 2-1/2"; verify per manufacturer
- Header sizing per span table; king and jack stud count per plan
- Notching / boring limits: bore max 40% of stud depth, notch max 25%, hole min 5/8" from edge
- Tub / shower blocking at 32"–34" for grab bars, cabinet blocking at 54" and 84" for uppers
Permits & inspection milestones
- Shear wall / hold-down inspection where required before sheathing is covered
Field tips & tricks
- Crown every stud the same direction and cull the bananas. Drywall shows every bowed stud under raking light.
- String-line the top plate of long walls before sheathing. Straight walls make cabinets and trim fast.
- Add backing for towel bars, TVs, closet shelves and handrails now — photograph it with a tape for the drywall punch.

Shear Walls, Straps & Hold-downs
The lateral system: sheathing, nailing patterns, and the connectors that resist wind and seismic load.
Framing
Inspections
Prerequisites & handoff
- Walls framed and braced
- Structural sheet showing shear schedule
Critical measurements & tolerances
- Nailing per shear schedule, commonly 8d at 6" edge / 12" field; 4" or 3" edge for high-load panels
- Nails set flush — overdriven more than 1/16" loses shear capacity and fails inspection
- Panel edge gap 1/8" for expansion
- Hold-down anchors torqued and squarely bearing; strap nailing 100% filled
Permits & inspection milestones
- Framing / shear inspection
- Special inspection where the structural sheet calls for it
Field tips & tricks
- Set the nail gun pressure with a test panel each morning. Overdriven nails are the #1 shear failure.
- Fill every hole in every strap. A half-nailed strap is worth nothing to an engineer or inspector.

Floor System, Roof Trusses & Sheathing
Set the floor and roof structure, brace it permanently, and sheathe.
Framing
Roofing
Prerequisites & handoff
- Walls plumb and braced
- Truss package approved by engineer
- Crane access confirmed
Critical measurements & tolerances
- Subfloor glued and screwed; deflection / squeak-free, flat within 1/4" in 10'
- Truss bearing min 3" on wood, per truss drawing; never cut or notch a truss
- Permanent lateral bracing and web bracing exactly per truss engineering
- Roof sheathing H-clips where specified, 1/8" panel gap
- Attic access min 22" x 30" with 30" headroom above
Permits & inspection milestones
- Framing inspection including truss bracing
Field tips & tricks
- Keep the stamped truss drawings on site. Inspectors check bracing against them, not against habit.
- Any truss modification needs written engineering. Field-cutting a web is a rebuild, not a repair.

Roof Dry-in, Windows & Exterior Doors
Get the house watertight — the milestone that lets interior trades start.
Roofing
Framing
Prerequisites & handoff
- Roof sheathed
- Windows on site and inspected for damage
Critical measurements & tolerances
- Underlayment laps 2" horizontal, 4" vertical minimum; ice barrier from eave to 24" inside the warm wall in cold climates
- Valley and step flashing min 4" each side; kickout flashing at every roof-to-wall termination
- Window flashing sequence: sill pan first, jambs, then head flashing over the WRB
- WRB laps shingle-style: upper course over lower, 6" min vertical laps
Permits & inspection milestones
- Weather barrier / window flashing inspection in many jurisdictions
Field tips & tricks
- The kickout flashing is the single cheapest part on the job and the cause of the most expensive wall rot. Never skip it.
- Shim windows at the sill only at bearing points, and never through the sill pan.
- Flash sill pans before the window, tape jambs over the flange, leave the head lap under the WRB — water always wins arguments about order.
