Inspect Access Routes
The access inspection verifies your stairs and egress window meet safety codes. Passing this milestone allows you to proceed with closing walls.
Why This Inspection Matters
The access and egress inspection is a critical checkpoint in your attic conversion. It verifies that your stairs are safe for daily use and your egress window provides a viable emergency escape route. Failing this inspection after closing walls means expensive demolition and rework. More importantly, these features protect your family - stairs are a leading cause of home injuries, and egress windows save lives in fires. Taking time to prepare thoroughly ensures you pass the first time and can move forward confidently.
Tools & Materials You'll Need
Step-by-Step Guide
Pre-Inspect Stair Dimensions
Verify all stair measurements meet code before scheduling inspection:
Self-Check Measurements:
- *Stair width: Minimum 36" clear between walls/rails
- *Headroom: Minimum 6'8" at all points along walking line
- *Riser height: Maximum 7.75", all within 3/8" of each other
- *Tread depth: Minimum 10" from nosing to nosing
- *Nosing: 3/4" to 1.25" projection beyond riser
- *Landing: Minimum 36" in direction of travel at top and bottom
Critical: Measure every riser. The most common failure is riser variation exceeding 3/8 inch. Use a story pole to compare all risers quickly.
Verify Handrail Installation
Handrails are carefully scrutinized for safety compliance:
Height Requirements
- * 34-38 inches above tread nosing
- * Measured vertically from nosing
- * Consistent height throughout
Graspability
- * 1.25-2 inch diameter circular section
- * Or equivalent graspable profile
- * Smooth, continuous surface
- *Continuity: No breaks along full stair length
- *Returns: Ends must return to wall or post (no sharp ends)
- *Balusters: Maximum 4 inches apart - test with 4" sphere
- *Stability: No wobble when pulled firmly
Test Egress Window Operation
The egress window must function properly for emergency escape:
Egress Window Checklist:
- ☐Minimum 5.7 square feet clear opening (measure actual opening)
- ☐Minimum 24 inches opening height
- ☐Minimum 20 inches opening width
- ☐Maximum 44 inches sill height from floor
- ☐Opens without tools or special knowledge
- ☐Opens fully and stays open
- ☐Screen removes easily from inside
Test Tip: Have a family member who didn't install the window try to open it. If they struggle, an inspector or someone escaping a fire will too.
Review Structural Framing
Ensure structural elements are visible and properly installed:
- *Stairwell headers: Double headers with proper joist hangers
- *Trimmers: Double trimmers on sides of opening
- *Hangers: Properly sized and nailed joist hangers at all connections
- *Egress framing: Header, jack studs, sill visible
- *Stringer attachment: Securely fastened at top and bottom
Photo Documentation: Take photos of all framing connections before inspection. This creates a record and helps if questions arise later.
Schedule and Attend Inspection
Prepare for a smooth inspection process:
- Call building department to schedule (often 24-48 hours notice required)
- Confirm what specific inspections are included
- Have all permits posted visibly at the job site
- Clear access paths - inspector needs to see and measure everything
- Be present during inspection to answer questions
- Bring tape measure and notepad for inspector comments
- Ask questions if anything is unclear
If You Fail:
- * Get specific written details on what failed and required corrections
- * Ask for code section references
- * Schedule re-inspection after making corrections
- * Don't proceed with other work until passed
Pro Tips
- ✓Do your own pre-inspection walk-through with the code book in hand
- ✓Clean up the work area - inspectors appreciate organized, professional job sites
- ✓Have good lighting available - bring work lights if needed
- ✓Ask the inspector if they want to see anything specific before they leave
- ✓Keep inspection records with your home documents for future reference
Frequently Asked Questions
What does the inspector check during a stair inspection?▼
Inspectors verify: stair width (minimum 36 inches), headroom (minimum 6'8"), riser height (maximum 7.75 inches), tread depth (minimum 10 inches), handrail height (34-38 inches), baluster spacing (maximum 4 inches), structural framing, and that stairs have landings at top and bottom.
What are common reasons for failing a stair inspection?▼
Common failures include: uneven riser heights (variations over 3/8 inch), inadequate headroom at any point, handrails at wrong height or not graspable, balusters spaced more than 4 inches apart, missing handrail on required side, and insufficient structural support at stairwell opening.
What egress requirements does the inspector verify?▼
Inspectors verify the egress window: minimum 5.7 square feet clear opening, minimum 24 inches high opening, minimum 20 inches wide opening, maximum 44 inches sill height from floor, opens without tools or special knowledge, and is accessible for emergency rescue from outside.
Can I cover walls before the access inspection?▼
No, do not install drywall or other wall coverings until the access inspection is passed. Inspectors need to see the structural framing around the stairwell opening, headers, joist hangers, and egress window framing. Covering these areas before inspection will require removal.
