Structural Inspection
Getting official approval before covering. The framing inspection verifies all structural work meets code and matches approved plans before insulation and drywall hide everything.
Why Structural Inspection Matters
The structural (framing) inspection is a critical checkpoint in your attic conversion. This is when a building official verifies that all the structural work - reinforced joists, support columns, collar ties, knee walls, and partition framing - meets building codes and matches your approved plans. Once you pass this inspection, you're cleared to proceed with insulation and drywall that will permanently cover the framing. Skipping or rushing this inspection can result in serious problems: uncovered code violations, structural issues that become expensive to fix later, or inability to get final approval for your project. Take time to self-inspect your work against plans before calling for official inspection - catching issues yourself is faster and cheaper than failed inspections.
What You'll Need Ready
Step-by-Step Guide
Complete All Structural Work
Ensure every structural element is finished before requesting inspection:
- Floor joist reinforcement complete with all sistering and blocking
- Support columns installed from foundation to attic
- Collar ties in place at correct height and spacing
- Knee walls framed with proper stud spacing
- All partition walls complete including door openings
- Headers installed over all openings
- Stair framing complete (if part of this inspection)
- Egress window rough opening correct size
Timing Note: Don't schedule inspection until ALL structural work is complete. Partial inspections waste everyone's time and may require re-inspection fees for the remaining work.
Self-Inspect Against Plans
Walk through your work as if you were the inspector:
Check Lumber Sizes:
- Joists match specified dimensions
- Posts/columns correct size
- Headers properly sized for spans
- Studs at correct spacing (16" OC)
Check Connections:
- Metal connectors where specified
- Correct nail/screw count per connection
- No missing fasteners or hangers
- Blocking at all intersections
Pro Tip: Create a checklist from your plans and physically check off each item. Take photos of completed work - useful for your records and for showing the inspector specific details.
Schedule the Inspection
Contact your building department to request the framing inspection:
- Call building department or use online scheduling system
- Have your permit number ready (on your posted permit)
- Request "framing" or "structural" inspection
- Ask about scheduling window (usually 1-5 business days)
- Confirm morning or afternoon time slot
- Get inspector's direct number if possible
- Ask what documents to have on-site
Scheduling Tip: Many jurisdictions now offer online inspection scheduling and can text you when the inspector is en route. Sign up for these services if available - they save time and reduce waiting.
Prepare Site for Inspector
Make the inspection go smoothly with proper preparation:
Site Preparation:
- Clear debris and materials from access paths
- Provide safe, stable access to all areas (ladder, temporary stairs)
- Ensure adequate lighting (have flashlights ready)
- Post permit in visible location
- Have approved plans accessible and organized
Be Present and Prepared:
- Be on-site or have contractor present
- Know where all structural elements are located
- Be prepared to answer questions about methods used
- Have tape measure ready for verification measurements
- Don't argue - ask questions respectfully if unclear
Address Any Corrections
If the inspection identifies issues, handle them promptly:
Common Issues Found:
- Missing or incorrect metal connectors
- Insufficient nailing at connections
- Wrong lumber size for spans
- Missing blocking at wall corners
- Headers undersized for openings
- Deviations from approved plans
Correction Process:
- Get written list of required corrections
- Ask for clarification if anything unclear
- Complete all corrections before calling back
- Schedule re-inspection (often free first time)
- Keep records of corrections made
Important: Never cover framing with insulation or drywall until you have passed inspection and have written approval. Covering before approval may require you to remove materials for re-inspection at your expense.
Pro Tips
- ✓Build a good relationship with your inspector - they can be a valuable resource for advice and clarification
- ✓Take photos of all structural work before inspection - useful for your records and for future reference
- ✓If using a contractor, have them present for the inspection - they can answer technical questions directly
- ✓Ask the inspector what they'll look for in the next inspection (mechanical/insulation) so you can prepare
- ✓Keep a copy of the passed inspection card or report - you'll need it for final inspection and potentially for insurance or sale
Frequently Asked Questions
What does a structural inspector look for in an attic conversion?▼
Inspectors verify that all structural work matches the approved plans and meets building codes. Key items include: floor joist sizing and spacing, support column placement and connections, collar tie installation, knee wall framing, partition wall construction, header sizes over openings, stair framing and rise/run dimensions, egress window rough opening size, and proper fastener types and spacing. They also check that any structural engineer specifications were followed exactly.
Can I do insulation or drywall before the framing inspection?▼
No. Installing insulation or drywall before framing inspection covers the work that needs to be verified. If you proceed without inspection, the inspector may require you to remove the covering at your expense to verify the underlying structure. Always wait for inspection approval before moving to the next phase. Some jurisdictions require separate inspections for framing, mechanical, insulation, and final.
What happens if I fail the framing inspection?▼
A failed inspection means corrections are required before work can continue. The inspector will provide a written list of deficiencies. Common issues include undersized lumber, incorrect spacing, missing connections or hardware, and deviations from approved plans. Make all corrections, then schedule a re-inspection (usually free for the first re-inspection, fees may apply for subsequent ones). Most issues can be corrected within a day or two.
How long does a framing inspection take?▼
A typical attic conversion framing inspection takes 30-60 minutes, depending on the project size and complexity. The inspector will walk through the space, check measurements, verify connections, and compare the work to approved plans. Being present to answer questions and provide access can speed the process. Schedule inspections for when you or your contractor can be on-site.
