HUD-code vs. modular vs. non-coded crew units
In Texas, HUD-code manufactured homes are built to the federal HUD code and regulated by TDHCA. Modular and industrialized buildings, including most dorm-style crew units, fall under TDLR's Industrialized Housing and Buildings program and are built to state-adopted building codes. "Non-coded" in the oilfield usually means a crew unit built as an industrialized building, not a HUD home. Which you need depends on the site's rules, how long you'll stay, and how you'll resell.
| HUD-code home | Modular / industrialized (TDLR) | "Non-coded" crew unit | |
|---|---|---|---|
| Built to | Federal HUD code | State-adopted IBC/IRC | Typically treated as an industrialized building |
| Texas regulator | TDHCA | TDLR | TDLR (bunkhouses not exempt) |
| Foundation | Installed per HUD/TDHCA rules | Per approved design | Non-permanent typical for dorm-type |
| Zoning acceptance | Widest for housing | Varies | Rural/industrial sites |
| Resale market | Homes and crew buyers | Commercial buyers | Crew and camp buyers |
| Max rooms per 16×76 | Typically 4–5 | Varies | Up to 7 |
