Modular home built without using hangers for floor joists or trusses

I inspected a modular home and it appeared that the floor joists did not have hangers or ledgers for end support; also roof trusses where they connect to the center beam did not have joist hangers. They were just face nailed. Conventional framing would not allow this but maybe modular has a different standard? Any thought or comments on this?

Have any photos?

I have but I doubt they would amplify what I’ve said…but here’s the long view of trusses…at the beam no hangers were installed.

Did you see any problems associated with the lack of hangers, Ray?

Those manufactured homes are engineered to the bare minimum at the factory but it seems like hangers would make the connection to the beam stronger, for sure.

Not much attic insulation either.

If I didn’t see any issues concerning that, I would probably move on. JMHO

Thanks…it had a permanent foundation…no steel chassis…I wonder if there is a printed standard for modular homes? I know I’ve had to remodel a few and if you ever had to take one apart it can be a lot of work…as they are put together better than most would think…

You know Ray, they’ve changed so much over the years that it could be called a modular. I just saw the hinged trusses and marriage wall and assumed it was a manufactured home. IDK for sure. I would have to be there. :smile:

What type of “truss” is this? what’s with all the missed roof decking nails?

Simon, they didn’t miss by much nailing the decking! I guess they figured close enough!

The QC must of been on break and when he came back it was time to go home when that unit was being built. :wink: :grin:

The problem with these units is there are no inspections. They are “engineered” homes the engineer says it meets standards and if the units are built off site there is no over sight. You would need to refer to the manufacturer to find out weather or not they required hangers.

A modular home has to comply to the local building code. A manufactured home has to comply with HUD.

Roy’s got it… :smile:

I guess from what I’ve noticed…for modular homes that the parts of the home built at the factory are still controlled by the manufacturer…and the parts that are assembled at the site are subject to local codes…Do you think that would be an accurate statement?

It still has to comply with the local code in all aspects…

Would architectural or engineered drawings take precedence over local standards? For instance if the engineered drawing indicate that the structure is designed to withstand certain wind speeds or loads, wouldn’t that take precedence over prescriptive standards that require certain nailing patterns or strapping?

Yes it would.

If the AHJ agreed.

Simon you should come to Florida & see the crazy CRAP I see!

Very nice! Makes one wonder the point of anchoring with nailing like that, especially in a place like Florida with the hurricanes. Yes, unfortunately I see it here, too. How else do you get the roof done in one day :slight_smile: Everyone is in a rush, speed vs quality.

Often when framers are nailing off a roof with a nail gun it’s easy to miss a rafter occasionally. The gun makes a different sound when it misses so they will just put in another row of nails beside it. So it doesn’t always mean that it’s not nailed.
