Blocking and backing
Blocking and backing is the added wood or steel a framer installs between studs so that whatever gets hung later has real backing to grab. Grab bars, cabinets, handrails, wall-mounted equipment, TVs and hardware all need a solid anchor, and drywall alone won't hold them. Because it's decided by finishes and fixtures that come much later, blocking has to be planned and placed before the walls close, then verified against the fixture layout.

Why it matters
Miss a piece of backing and the fix after drywall is cutting open a finished wall to add it: expensive, ugly and always at the worst time. It's a classic pre-drywall catch, because once the board goes up nobody can see where the blocking is or isn't.
What an inspector looks at
The check is that backing is present, at the right height and location, and sized for what it carries, matched against the fixture and casework plans rather than guessed. Missing or mislocated blocking gets logged while the framing is still open.
RTI is photo gated, so blocking is documented before drywall: shots that show each piece and its location against the wall, the only proof once the cavity is closed.
Guides that use it
- How to inspect drywall before closeRun the pre-drywall walk while the walls are open, then inspect board install: backing, fastening, board type, joints and finish level, with proof at each stage.
- How to inspect framingCheck framing before it's covered (members, connections, blocking, and openings against the drawings) so nothing gets buried behind sheathing or drywall.
- How to inspect doors and hardwareInspect doors and hardware against the door and hardware schedules (frames, fire ratings, hardware function, clearances, and closing) so every opening operates and latches.
- How to inspect acoustical ceilingsInspect acoustical ceilings from the grid up (layout, suspension and seismic bracing, level, panel fit, and coordination with everything landing in the tile) before they're loaded.

Related terms
- Dry-inThe point at which a building is closed to weather: roof, wall barrier and openings sealed enough to keep water out and let interior work start.
- SheathingThe structural panel skin over studs, rafters or joists that braces the frame and gives cladding, roofing and the barrier a base to attach to.
- Rough openingThe framed hole left for a window or door, sized a bit oversize so the unit can be set, shimmed plumb and square, and flashed.
- Weep holeA small opening left at the base of a cavity wall or window so water that gets behind the face has a path back out.
- Control jointA planned weak line cut or tooled into concrete or masonry so shrinkage cracks form where you want them instead of at random.
- Cold jointA weak seam left in concrete when fresh material is placed against a batch that has already started to set, so the two never fully bond.
Knowing the term is step one. Proving it is the job.
RTI holds the submit button until every mandatory item is answered and the photos are attached, then chains the record so it can be proven untouched later.
