I apologize as this may be a silly question. New home to friend has a second floor addition (might be original but hard to tell) with walk out attic. There is a little clearance between the ceiling and the roof. Issue is the bathroom exhaust fan vents to attic. To access, would have to get in attic and crawl about 30 feet on the joists. Any chance that the second floor ceiling could not support a 225 pound man.
You can go in the attic as long as you support your weight on the joists. I find it easier to take a series of 12" x 3/4" boards or strips of plywood into the attic to lay across the joists. Then I can belly slide. Trying to crawl on joists is pretty difficult and painful.
Thank you, thought that was the case but just wanted to make sure there would usually not be an instance where it could not support all that weight, me specifically.
Standard ceiling joists.... 2x6's - 2x8's..... on 16" centers are fine to be on.
It's attic truss systems you need to be careful of with 24" spacing and undersized "joists".
The attic is walkout with 4 foot doors and plywood (floor) from each bedroom with a bathroom, stairs in the middle. I have not ventured to check the system on top of the bedroom, bathrooms on the second floor but will keep that in mind when I get to check on the weekend.

Just to clarify, I will be getting on the second floor bedroom and bathroom but will access it from those attic doors. Will check the spacing on the ceiling before moving forward.

Lookup for best way to install header to support the 2, 2x10 joists, to enable installing a door?
There are 2, 2x4 ceiling trusses, so I think that the wall studs are non support.
I'm thinking that I could install a doubled up 2x4 header. Support it at the 1st stud on the left and attach the right side to the 4th stud on the left with jack studs and joists hangars.
I welcome any suggestions.
I want to add an opening under my stairs for storage. Can I cut this stud without
compromising the landing?
