Triple wide modular homes typically cost more than standard single-family builds, but they can be quicker to install and more energy efficient. Major cost drivers include foundation and site prep, interior finishes, and regional labor rates. This guide provides cost estimates in USD with clear low–average–high ranges to help with budgeting.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Base price (shell, 2,400–3,000 sq ft) | $360,000 | $420,000 | $660,000 | Includes factory-built modules, roof, exterior, basic interior walls |
| Delivery & set-up | $20,000 | $30,000 | $40,000 | Land travel, crane, site prep coordination |
| Foundation & site prep | $10,000 | $25,000 | $40,000 | Grading, footing, utilities rough-in |
| Permits & fees | $1,000 | $4,000 | $8,000 | Local permits, inspections |
| Interior finishes (optional upgrades) | $20,000 | $60,000 | $120,000 | Flooring, cabinets, countertops, fixtures |
| Electrical & plumbing upgrades | $5,000 | $15,000 | $40,000 | High-end systems, smart home prep |
| HVAC & energy features | $8,000 | $20,000 | $40,000 | SEER rating, heat pumps, insulation |
| Delivery/installation contingency | $5,000 | $15,000 | $30,000 | Unforeseen site constraints |
| Warranty & service packages | $2,000 | $6,000 | $12,000 | Structural and systems coverage |
| Taxes | $0 | $20,000 | $60,000 | Depends on location and price |

Overview Of Costs
Triplex-wide modular home pricing combines factory-built efficiencies with on-site work. Typical total project ranges from about $450,000 to $900,000, depending on size, finishes, and land costs. A shell-only approach lowers the initial outlay, while full custom interiors push toward the higher end. For budgeting, it helps to separate totals into base price, site work, and interior upgrades. Below are per-unit and total ranges to frame planning.
Cost Breakdown
4–6 key cost components influence overall price, with several niche drivers. A table below outlines common categories, typical ranges, and what commonly drives each line item.
| Category | Low | Average | High | What drives it |
|---|---|---|---|---|
| Materials | $360,000 | $420,000 | $660,000 | Module size, wall finishes, roofing, exterior siding |
| Labor | $30,000 | $60,000 | $120,000 | On-site assembly, utility hookups, interior finish trades |
| Equipment | $0 | $5,000 | $20,000 | On-site cranes, temporary power, heavy equipment rental |
| Permits | $1,000 | $4,000 | $8,000 | Local jurisdiction requirements, plan checks |
| Delivery/Disposal | $5,000 | $15,000 | $30,000 | Distance, site access, debris removal |
| Warranty | $2,000 | $6,000 | $12,000 | Structural and system coverage |
| Taxes | $0 | $20,000 | $60,000 | Location and purchase price |
What Drives Price
Key price drivers include module size and layout, energy efficiency, and site conditions. Larger footprints drive both base price and interior finishes. Regional labor rates vary, and added structure like vaulted ceilings or luxury kitchens can quickly raise totals. For triple wide homes, the footprint is typically 2,400–3,000 sq ft, with per-square-foot costs ranging from roughly $150 to $220 excluding land and site work.
Ways To Save
Cut costs by prioritizing essential features and staged upgrades. Consider a mid-range finish package initially, with later updates as budgets allow. Options like standard cabinetry, mid-tier flooring, and conventional countertops can reduce upfront costs while preserving long-term value. Plan for long-term savings through improved insulation, air sealing, and high-efficiency HVAC.
Regional Price Differences
Prices vary across regions, reflecting labor markets and permitting climates. In the Northeast, higher labor and permitting costs can add 10–20% versus the Midwest or South. Urban markets may see +15% compared with rural sites due to logistics and crane fees. A midwest rural project could be closer to the lower end of the range, while coastal urban builds trend higher overall.
Labor, Hours & Rates
Labor is a major portion of on-site costs. Typical labor hours for assembly and interior work scale with size, complexity, and finish level. A 2,400–3,000 sq ft triple wide often requires 6–12 weeks from delivery to move-in readiness, including interior trades and utility hookups. Hourly rates for on-site crews commonly run from $50 to $120 per hour depending on region and trades.
