Framing Inspection: Pass on First Try
The framing inspection is where structural integrity is verified. This is your chance to prove the skeleton of your house is built to code—and it's one of the most detailed inspections you'll face. Here's everything you need to pass on the first attempt.
All framing must be complete before calling for inspection, but no interior wall covering can be installed. Once you drywall, the inspector can't verify the framing. This is a common mistake that forces you to tear out drywall.
When to Schedule
Schedule after all framing is complete but BEFORE any wall covering (drywall, sheathing on interior). Notice required: 24-48 hours typically, up to 72 hours in busy seasons.
Critical windows:
- All walls, floors, and roof structure must be complete
- All structural beams and headers installed
- Stair framing complete
- Fire blocking installed
- Structural sheathing on exterior is OK (inspectors expect it)
- Interior wall covering must NOT be installed yet
Schedule for mid-week (Tuesday-Thursday). Gives you the weekend to finish any last-minute items, and you'll get re-inspection faster if needed.
Weather consideration: Inspectors will inspect in light rain but typically won't climb wet roofs. Have a backup date ready.
What the Inspector Checks
The inspector works the structure top to bottom: structural members, floor framing, wall framing, roof framing, connections, fire/draft stopping, and stairs. The spec tables below are what they verify against your approved plans and the IRC.
Structural Members

| Fastening schedule | Proper nail size and type; correct spacing; toe-nailing where specified; metal connectors properly installed |
| Hurricane ties/seismic ties (if required) | Installed at every rafter/truss to top plate connection; correct type for wind/seismic zone; all nail holes filled |
Fire and Draft Stopping
Fire blocking and draft stopping are often forgotten and easy to overlook on inspection day. Mark every location clearly before the inspector arrives.
Fire blocking (IRC R302.11):
- At 10' vertical in walls
- At soffits
- At cove molding spaces
- Between stories
- In furred spaces
Draft stopping (IRC R302.12 — verify your jurisdiction's adopted edition):
- Floor/ceiling assemblies with usable space above and below (so concealed space does not exceed 1,000 sq ft)
Note: the "attic every 3,000 sq ft" rule is an IBC provision (commercial-type construction), not IRC R302.12. Under the IRC, attic draftstopping is generally not triggered the same way; confirm any attic requirement with your building department.
Stairs
| Requirement | Value / spec |
|---|---|
| Maximum rise | 7-3/4" per IRC R311.7.5.1 |
| Minimum run | 10" |
| Variation between risers | Maximum 3/8" |
| Minimum width | 36" |
| Minimum headroom | 6'8" |
| Stringers | Properly sized for span; minimum 3 stringers for 36" width; proper bearing at top and bottom; attached securely to structure |
| Landing | Minimum 36" deep; width at least as wide as stairway; level (maximum 1/4" slope) |

Top 15 Failure Points
Based on a multitude of framing inspections, these are the issues that most often send owner-builders back for a re-inspection.
1. Missing or Improper Joist Hangers
Hangers missing nails, wrong size, or installed incorrectly. Code requirement: IRC R502.6 — all joints must be properly supported and connected.
| Re-inspect | Cost |
|---|---|
| 2-4 days | $300-$800 (carpenter callback to fix hangers throughout house) |
Specific issues:
- Not every nail hole filled (each hole must have a nail)
- Wrong size hanger for joist dimension (2x8 hanger for 2x10 joist)
- Using common nails instead of joist hanger nails
- Hanger installed upside down or sideways
- Hanger nails too long and poking through
How to fix: Replace incorrect hangers, fill all nail holes with proper hanger nails
Prevention: Buy correct hangers, use only joist hanger nails, fill every hole, double-check before calling inspection
2. Headers Undersized or Improperly Supported
Header too small for span or not bearing on jack studs. Code requirement: IRC R602.7 — headers must be sized per span tables.
| Re-inspect | Cost |
|---|---|
| 3-7 days (significant structural work) | $500-$2,000 depending on number of openings and complexity |
Specific issues:
- Header one size too small (4x8 when 4x10 required)
- Header spanning to king stud instead of jack stud
- Built-up header not properly nailed together
- No jack studs under header ends
- Header not bearing on full width of jack stud
How to fix: Install properly sized header with correct support
Prevention: Calculate header sizes before framing, verify against IRC span tables, ensure jack studs under all headers
3. Missing Fire Blocking
Required fire blocking not installed in walls or concealed spaces. Code requirement: IRC R302.11 — fire blocking required at specific locations.
| Re-inspect | Cost |
|---|---|
| 1-3 days | $200-$600 (if walls still open; much more if drywall started) |
Where required:
- Walls at 10' vertical intervals
- Connection between horizontal/vertical concealed spaces
- Soffits and drop ceilings
- Cove molding areas
- Between floors
How to fix: Install 2x blocking or two layers 1x material at required locations
Prevention: Mark fire blocking locations during layout, install as you frame, verify before calling inspection
4. Improper Stair Dimensions
Stair risers or treads outside code requirements. Code requirement: IRC R311.7.5 — specific stair dimension requirements.
| Requirement | Value |
|---|---|
| Maximum riser | 7-3/4" |
| Minimum tread | 10" |
| Maximum riser variation | 3/8" |
| Minimum width | 36" |
| Minimum headroom | 6'8" |
| Re-inspect | 3-7 days |
| Cost | $800-$2,500 (complete stair rebuild) |
Common issues:
- Last riser different height (forgot to account for flooring)
- Inconsistent riser heights
- Insufficient headroom
- Winders don't meet minimums
How to fix: Rebuild stairs to correct dimensions
Prevention: Carefully calculate rise/run before cutting stringers, verify actual floor-to-floor height including finish flooring, measure each riser/tread
5. Excessive Notching or Boring of Joists
Joists notched or drilled beyond code limits. Code requirement: IRC R502.8 — specific limits on notching and boring.
| Re-inspect | Cost |
|---|---|
| 2-5 days | $400-$1,500 depending on number of joists and accessibility |
Limits:
- Notches: Maximum 1/6 depth at ends, 1/3 depth in middle third
- Holes: Maximum 1/3 depth, minimum 2" from edges, no closer than 2" to other holes
- Never notch middle third of span
- Never notch engineered lumber or I-joists
How to fix: Sister reinforcing joist alongside damaged member, or install full sister if severely compromised
Prevention: Route plumbing and electrical properly, know limits before cutting, never let plumber/electrician cut without supervision
6. Insufficient Bearing for Beams
Beams don't have adequate bearing surface at supports. Code requirement: IRC R502.6 — minimum 1.5" bearing for sawn lumber, 3" for engineered beams.
| Re-inspect | Cost |
|---|---|
| 3-7 days (structural modification) | $400-$1,200 per beam/post connection |
Specific issues:
- Beam bearing on less than required width
- Beam overhanging post
- No positive connection between beam and post
- Bearing surface not level
- Posts not adequately sized for load
How to fix: Add proper bearing, install correct post caps, resize posts if needed
Prevention: Use post caps for all beam-to-post connections, measure bearing surface, ensure minimum bearing
7. Roof Truss Modifications
Any field modification to engineered roof trusses. Code requirement: IRC R802.10.3 — trusses shall not be altered.
| Re-inspect | Cost |
|---|---|
| 1-3 weeks (engineering time + repairs) | $2,000-$8,000 (engineering + reinforcement) |
What I see:
- Cut bottom chord for attic access
- Cut webs for HVAC duct
- Cut top chord for valley
- Notched or drilled anywhere
- Missing bracing per engineer drawings
How to fix: Usually requires structural engineer to design repair (expensive)
Prevention: NEVER cut trusses. Route all mechanicals around trusses. Get engineer involved before any modifications.
8. Missing Hurricane Ties or Seismic Clips
No hurricane ties connecting rafters/trusses to top plate. Code requirement: IRC R802.11 — connection required per wind speed and seismic zone.
| Re-inspect | Cost |
|---|---|
| 2-4 days | $300-$1,000 (ties + labor to install on all rafters) |
Requirements vary by location:
- Basic wind speed determines connection strength
- Seismic zone determines requirements
- May need specific tie model (check approved plans)
- Must be installed on every rafter/truss
How to fix: Install proper ties at every rafter/truss location
Prevention: Know your wind/seismic requirements, buy correct ties, install on every rafter as you frame roof
9. Improper Wall Bracing
Insufficient or incorrectly installed wall bracing. Code requirement: IRC R602.10 — braced wall panels required.
| Re-inspect | Cost |
|---|---|
| 3-7 days | $500-$2,000 depending on amount needed |
Methods (depends on seismic/wind zone):
- Let-in bracing at 45 degrees
- Structural sheathing panels
- Diagonal metal strapping
- Portal frames
Common issues:
- Not enough braced wall panels for building configuration
- Bracing doesn't meet length requirements
- Improper nailing of sheathing
- Let-in bracing not continuous
How to fix: Add additional bracing per code requirements
Prevention: Calculate bracing requirements before framing, follow approved plans, verify proper installation
10. Inadequate Headroom Over Stairs
Headroom less than 6'8" at any point along stairs. Code requirement: IRC R311.7.2 — minimum 6'8" headroom measured vertically.
| Re-inspect | Cost |
|---|---|
| 3-7 days (can be complex) | $800-$3,000 depending on what's blocking |
How it happens:
- Ductwork installed too low
- Beam placed incorrectly
- Ceiling height not calculated properly
- Attic access door location
How to fix: Raise obstruction, reroute ductwork, or rebuild stairs with different pitch
Prevention: Calculate headroom before building stairs, verify clearance at all points along stair run
11. Rafters with Improper Bird's Mouth
Bird's mouth cut removes too much material from rafter. Code requirement: IRC R802.7.1 — notch depth shall not exceed 1/3 rafter depth.
| Re-inspect | Cost |
|---|---|
| 3-7 days | $600-$2,000 (sistering or replacing rafters) |
Typical requirement:
- Maximum bird's mouth depth: 1/3 of rafter depth
- Remaining rafter depth must be adequate for span
- Must bear on full width of top plate
How to fix: Sister rafters to reinforce if cut too deep, or replace rafters
Prevention: Mark bird's mouth depth before cutting, verify against 1/3 depth rule, cut conservatively
12. No Blocking or Bridging Where Required
Missing blocking between joists or under bearing walls above. Code requirement: IRC R502.7 — blocking required at bearing points.
| Re-inspect | Cost |
|---|---|
| 2-4 days | $300-$800 (accessing and installing blocking) |
Where required:
- Under all bearing walls above
- At joist laps over beam
- Cantilever ends
- Joist runs over 8' (depending on jurisdiction)
How to fix: Install solid blocking at required locations
Prevention: Install blocking as you frame, mark locations on plans, verify before inspection
13. Subfloor Not Properly Fastened
Subfloor not glued and nailed per schedule, or improper spacing. Code requirement: IRC R503.2.1 — fastening per approved plans and manufacturer.
| Re-inspect | Cost |
|---|---|
| 2-4 days | $400-$1,200 (labor to add fasteners) |
Requirements:
- Glued (construction adhesive) and nailed
- 6" OC at edges, 12" OC in field (typical)
- 1/8" spacing between sheets for expansion
- Tongue and groove oriented correctly
How to fix: Add additional fasteners, may require replacing sheets not glued
Prevention: Glue every sheet, follow nailing schedule, use proper spacing
14. Openings Not Properly Framed
Window or door openings missing king studs, jack studs, or cripples. Code requirement: IRC R602.7 — opening framing requirements.
| Re-inspect | Cost |
|---|---|
| 2-4 days | $200-$600 per opening |
Proper framing:
- King studs full height each side of opening
- Jack studs (trimmers) supporting header
- Cripples above header to top plate
- Cripples below sill (windows)
- Double sill for wider windows
How to fix: Add missing framing members
Prevention: Follow standard framing practices, verify each opening has all required members
15. Built-Up Beams Not Properly Fastened
Doubled or tripled beams not nailed together properly. Code requirement: IRC R602.7.2 — built-up beams must be fastened together.
| Re-inspect | Cost |
|---|---|
| 1-3 days | $150-$400 (labor to add nails) |
Requirements:
- Nailed together with proper schedule (typically 16d at 16" OC staggered)
- All layers of same dimension
- No gaps between layers
- Bearing on jack studs, not king studs
How to fix: Add fasteners to meet schedule
Prevention: Nail built-up beams as you assemble them, don't rely on a few nails
If You Fail
Stay Calm
Framing inspection failures are common. Most are straightforward fixes.
Get Written Details
Ask inspector for:
- Specific code section violated
- Exact location of problem
- How to correct it properly
- Whether correction requires engineer review
Common Fixes and Timeline
| Issue | Fix | Cost | Timeline |
|---|---|---|---|
| Missing fire blocking | Install blocking in walls | $200-$600 | 1-3 days |
| Joist hangers incomplete | Add missing nails | $100-$300 | 1-2 days |
| Undersized header | Replace with correct size | $500-$2,000 | 3-7 days |

| Stair dimensions wrong | Rebuild stairs to code | $800-$2,500 | 3-7 days |
| Cut or modified truss | Engineer design repair | $2,000-$8,000 | 1-3 weeks |
Re-Inspection Process
- Make all corrections noted (don't skip any)
- Take photos of corrections
- Call for re-inspection
- Be present for re-inspection
- Show inspector what was corrected
Usually 2-4 days for scheduling.
Cost of Delay
One week delay = $1,500-$3,000 in direct costs plus schedule disruption. Pass on first try by preparing thoroughly.
Each day framing inspection is delayed costs:
- Holding costs: Construction loan interest, insurance, etc. ($50-150/day)
- Subcontractor delays: Electrician, plumber, HVAC scheduled but can't start
- Weather risk: Longer exposure before weather-tight
- Cascade delays: Every trade after framing is now delayed
Special Considerations
Engineered Lumber
They'll verify no field modifications.
Special rules:
- Follow manufacturer installation instructions exactly
- Don't notch or drill I-joists (web knockouts only)
- Proper bearing and blocking required
- Temporary bracing often needed during installation
Shear Walls and Hold-Downs
If you need to change anything, get an engineer involved early.
If required (seismic/wind zones):
- Location must match approved plans exactly
- Proper fastening schedule critical (often closer spacing)
- Hold-down bolts must be installed correctly
- No deviation from engineered design allowed
