Remodelling and improvements
What you can change, what needs approval, and the structural limits that are not obvious.
1 min read
Manufactured homes take cosmetic work well, flooring, paint, fixtures, cabinets, worktops. Structural changes are a different matter, and the constraints are not obvious from inside.
Walls may be structural in ways they would not be in a house. In a manufactured home the roof load path and the way the sections hold together mean an apparently ordinary partition can be doing real work. Do not remove or open a wall without an opinion from someone who understands manufactured-home construction, and on a multi-section home, treat anything near the marriage line as structural until told otherwise.
Additions and attached structures need care. A deck, carport, awning, or room addition must generally be self-supporting on its own foundation rather than hung off the home, because the home moves as its piers settle and a rigidly attached structure will either tear at the join or transfer load the frame was not designed for.
Anything touching the roof, the exterior envelope, plumbing, gas, or electrics is worth a professional and, usually, a permit. HUD-code homes are federally regulated as manufactured, but alterations and site work are typically governed locally, so check before rather than after.
If you are in a community, get written approval before starting. Rules commonly cover decks, sheds, carports, fences, and exterior colour, and improvements made without approval may have to be removed at your expense, and may not be yours when you sell.
Key points
- Cosmetic work is straightforward; structural change is not.
- Walls may be load-bearing in non-obvious ways, get an opinion first.
- Decks and additions should be self-supporting, not attached to the home.
- In a community, get written approval before you start.
Watch out
Attaching a deck or addition rigidly to the home is a common and costly mistake. The home settles and moves on its piers; the attached structure does not, and something has to give.
