📋 Step-by-Step Guide (6 Steps)
Anchor Sill Plates to Foundation
Roll out sill gasket foam along the concrete foundation perimeter to create a capillary break. Drill holes in pressure-treated 2x6 lumber matching foundation anchor bolt locations. Slide boards over bolts and torque down heavy-duty washers and nuts until flush.
- • Continuous white/blue foam visible beneath treated plate
- • Washers compressed tight to timber on every bolt
- • Chalk line reveals straight alignment along slab edge
- • Forgetting sill gasket beneath treated wood
- • Overtightening nuts and splitting the wood
Assemble and Raise Wall Frames
Layout top and sole plates together, marking stud locations every 16 inches on center. Lay studs between plates on the subfloor deck and drive two 16d nails per stud connection. Lift the wall assembly upright, align the bottom plate with your chalk line, and nail temporary diagonal 2x4 braces to secure it.
- • Vertical studs aligned plumb at 16-inch on-center spacing
- • Diagonal 2x4 kickers anchored firmly to subfloor deck
- • Top and bottom plates flush with outer floor boundary
- • Failing to mark stud layout on both plates simultaneously
- • Leaving wall unbraced while standing next section
Sheathe Exterior Walls with OSB
Fasten 7/16-inch OSB panels vertically or horizontally across the exterior studs with 8d ring-shank nails. Space nails 6 inches apart on panel edges and 12 inches apart along intermediate field studs. Leave a 1/8-inch expansion gap between adjacent panel edges to prevent buckling from humidity.
- • Panels fully cover wall frame with staggered horizontal seams
- • Nail heads flush with surface without piercing the outer veneer
- • Visible 1/8-inch coin-width gaps between panel edges
- • Butting OSB sheets tight against each other with zero gap
- • Over-driving nails deep through the outer strand layer
Set and Brace Roof Trusses
Lift engineered trusses onto the double top plates using mechanical hoists or team lifts according to structural plans. Plumb each truss and secure it to the top plate using metal hurricane ties and specified structural screws. Nail continuous lateral bracing across truss webs to lock the roof structure in plane.
- • Truss peaks form a straight, level horizontal ridge line
- • Metal hurricane ties seated flush and fully nailed at top plates
- • Continuous 2x4 lateral bracing running perpendicular across truss chords
- • Omitting web/lateral bracing before roof sheathing
- • Toe-nailing top plates without approved hurricane clips
Install Weather-Resistant Barrier and Flashing
Wrap the exterior sheathing with housewrap, starting from the bottom of the wall and working upward with a 6-inch horizontal overlap. Fasten with plastic-capped cap nails or staples every 12 to 18 inches. Seal all horizontal and vertical seams tightly using manufacturer-approved acrylic seam tape.
- • Smooth, unwrinkled housewrap covering all exterior wood sheathing
- • Upper courses overlapping lower courses in shingle fashion
- • All seams completely covered with red or white building tape
- • Reverse-lapping housewrap so water can funnel behind sheets
- • Leaving seams un-taped or using standard duct tape
Rough-In Mechanical, Electrical, and Plumbing
Bore holes through the center of studs for electrical Romex cables, PEX water lines, and DWV drain pipes. Pull wiring to outlet and switch boxes, leaving 8 inches of free conductor inside each box. Install steel nail plates on the face of every framing member where pipes or wires pass within 1-1/4 inches of the stud edge.
- • Wires and pipes run dead-center through stud depth
- • Metal anti-puncture nail plates installed on stud faces over all bore holes
- • Electrical boxes rigidly attached and protruding 1/2 inch past stud face for drywall
- • Drilling holes too close to the front edge of the stud without nail plates
- • Overfilling bored holes with too many Romex cables
