Core Answer
Check the true clear opening, door swing or panel removal, nearby obstructions, insulation, and the actual service task before locating the door.

What to Check First
- Identify the device or area that must be reached
- Measure the clear opening, not only nominal door size
- Check hinge swing, latch access, and panel removal path
- Account for external insulation and ceiling access
- Test reach with the expected hand tool or inspection method
Ask Foreman
Will this access door give a real clear opening to inspect, reset, clean, or service the device after all finishes are installed?

Do Not Do This
Do not size the door by habit, place the hinge against an obstruction, or count a ceiling tile opening as usable duct access.
Why This Matters
A door can technically exist and still be useless when the technician cannot reach the device or operate a tool.
Verify against: device manufacturer instructions, approved details, project access requirements, commissioning/maintenance needs.
