Quick answer
A triple wide manufactured home is a HUD-certified residence built in three separate sections at the factory, transported on chassis, and joined on-site into a single home up to 42′ wide and 4,500 sq ft. Triple wides accommodate 4–5 bedrooms, 2–3 bathrooms, and expansive great rooms that single and double wides physically can’t deliver. Typical 2026 factory price: $135,000–$425,000 depending on size and finish. All-in installed: $185,000–$535,000. Triple wides represent under 8% of manufactured-home production in 2026 because they require specialized transport coordination (three oversize-load permits, three crane setups) and wider lots. Tiny Homes USA ships triple wides through our Custom Build program.
What makes a triple wide different
The basic geometry: instead of one section (single wide) or two sections (double wide), a triple wide ships in three sections joined along two marriage lines. Each section caps at 14′ wide for legal interstate transport. Three sections joined = 42′ of total width.
That extra section unlocks:
- 4–5 bedroom layouts: double wides max at 4BR; triple wides comfortably fit 5BR + 3BA
- Larger great rooms: 30′+ wide open spaces possible with proper engineering across two marriage lines
- Dual primary suites: in-law accommodations on one section, family primary on another
- Real formal dining + breakfast nook: single and double wide layouts compromise on this
- Bonus rooms: game room, home theater, office — in addition to the bedroom count
The flip side: more complex transport, longer setup, wider lot required, and higher price point.
Triple wide sizes and 2026 pricing
| Size | Bedrooms | Factory price | All-in |
|---|---|---|---|
| 2,000 sq ft (entry) | 4BR/2BA | $135K–$170K | $185K–$245K |
| 2,800 sq ft | 4BR/2.5BA | $185K–$235K | $245K–$325K |
| 3,400 sq ft | 5BR/3BA | $245K–$315K | $325K–$425K |
| 4,200 sq ft | 5BR/3.5BA | $315K–$425K | $415K–$535K |
Compare against equivalent site-built construction at $175–$300/sq ft: 3,400 sq ft stick-built runs $595K–$1,020K. Triple wide saves 40–55%.
Triple wide transport and setup complexity
Setting a triple wide is more complex than single or double wide:
- Three transports: each section ships separately on a flatbed trailer under oversize-load permits. Three trucks coordinate arrival to the lot, often a day or two apart.
- Three crane setups: a crane sets each section onto the foundation in sequence. Each section needs marriage-line alignment to the previous one.
- Two marriage-line joins: after all three sections are set, the marriage seams between section 1-2 and section 2-3 are finished out. Plumbing, HVAC ducts, and electrical that cross marriage lines are connected.
- Larger lot requirements: minimum 60-70′ of buildable width to accommodate the 42′ assembled home + setbacks. Crane needs 80′ of overhead clearance and equipment-staging space.
- Setup timeline: 3–7 days to set and join all three sections. Add 2–4 weeks for finish-out after set.
Who triple wide is right for (and who it isn't)
Triple wide makes sense if:
- You need 5BR + 3BA in a single-story layout
- You have a large rural or suburban lot (1+ acre, 70′+ buildable width)
- You’re downsizing from a 3,000+ sq ft site-built home and want similar space at lower cost
- You’re building a multi-generation home (in-law suite + family)
- You want manufactured-home pricing efficiency without the size compromise
Triple wide doesn’t make sense if:
- Your lot is narrower than 60′ of buildable width
- You need only 3BR or 4BR — a double wide handles that for less money and faster delivery
- You want HOA approval — most HOAs that allow manufactured homes still cap at double wide
- Your timeline is tight — triple wide build + setup adds 4–6 weeks vs double wide
- You want 2-story — HUD code is single-story; use modular for multi-story large homes
