• All headers properly sized for openings per approved plans
• Cripples, trimmers, and king studs installed at all windows and doors
• Blocking installed where required — mid-height in tall walls, at drywall butt joints, at grab bar locations in bathrooms
• Bearing walls properly supported — no unsupported point loads
• All framing members within 1/4" of plumb and straight
• Top and bottom plates doubled where required

☐ Electrical Checklist

• All rough-in wiring run and boxes installed per approved electrical plans

• Wire stapled within 12" of boxes and every 4.5 ft per CEC 334.30
• Wire not kinked, damaged, or run against sharp edges without protection
• Nail plates installed wherever wire passes through framing within 1-1/4" of face — CEC 300.4(A)
• Box fill not exceeded — verify conductors, devices, and clamps against NEC/CEC table
• All boxes at correct height and set depth for finished wall thickness
• AFCI and GFCI locations per plan
• Smoke detector and CO detector locations roughed in per plans

☐ Plumbing Checklist

• Water supply lines pressure-tested and test documented

• Vent pipes continuous to roof — no missing sections
• Access panels provided for shutoffs and cleanouts per plan

☐ Fireblocking Checklist

• Fireblocking at all top plate penetrations — every pipe, wire, and duct passing through a top plate requires blocking or approved intumescent sealant
• Fireblocking between floors — required at floor-to-floor interfaces in balloon framing
• Fireblocking in soffits, drop ceilings, and furred spaces — at maximum 10-foot intervals
• Fireblocking at stair stringers where stairs run adjacent to a concealed space
• Fireblocking material correct — 2x lumber, 2 layers of 1x, 23/32" wood structural panel, 3/4" particleboard, 1/2" gypsum, or listed intumescent sealant

• Plates cover the full width of the framing member at the penetration
• Both supply and drain pipes protected
• Electrical wires protected at notched studs and holes near the edge of framing
• Gas lines — nail plates or sleeve protection at all penetrations

☐ Insulation Checklist

• Exterior walls insulated to R-value required by California Energy Code Title 24 — typically R-15 or R-21 in San Diego's climate zone
