Prefab House Cost 2026: What You Actually Pay, From Factory to Foundation
Prefab house prices are quoted in two very different ways, and the gap between them confuses most buyers. A factory may quote USD 50-150 per square foot, but that figure covers only the structure at the factory gate. The real cost of a prefab home includes freight, import duty, tax, foundation, crane hire, utility connections, and finishing. This guide breaks the full chain down so you can budget accurately, whichever type of prefab you are comparing.
The Two Ways Prefab Prices Are Quoted
- Per square foot (USD/sq ft): commonly used for panelized and modular homes. USD 50-300 per sq ft depending on finish level and local labour content.
- Per unit (container house, cabin, tiny home): quoted as an FOB unit price, e.g. USD 3,800-13,800 for a 10ft-40ft expandable container house, with everything else itemised separately.
Always ask which basis a quote uses, and insist on a line-item breakdown before comparing suppliers.
2026 Price Guide: Full Chain From Factory to Installed
The table below models a mid-size prefab project (about 60-100 sq m / 650-1,100 sq ft of living space) using either a modular kit or container-based units. Figures are indicative ranges in USD; local conditions move every line.
| Cost item | Range (USD) | Notes |
|---|---|---|
| Factory price (FOB) | 15,000-60,000 | USD 50-150/sq ft for modular kits; USD 3,800-13,800 per container unit for container-based homes |
| Ocean freight | 2,000-8,000 | Container load from China to most destinations; varies with port and season |
| Marine insurance (0.3-0.5% of CIF) | 60-300 | Recommended on every shipment |
| Import duty | 0-30% of goods value | HS 9406 (prefabricated buildings): 0% under many FTAs (China-ASEAN Form E, ChAFTA Australia, NZ-China FTA); 2.0-2.7% into the EU; 25% Section 301 into the US for Chinese-origin steel buildings |
| VAT / GST / sales tax | 5-23% of landed value | 10% GST Australia, 15% GST New Zealand, 5% GST Canada, 20% VAT UK, 23% VAT Ireland |
| Customs clearance & inland delivery | 500-3,000 | Broker fees plus haulage to site |
| Foundation | 3,000-20,000 | Concrete slab, screw piles, or pier-and-beam; depends on soil and frost depth |
| Crane / placement | 1,000-5,000 | One to two days of lifting for modular or container units |
| Assembly, utilities & finishing | 8,000-30,000 | Connecting modules, electrical, plumbing, HVAC, interior finish |
| Total installed cost | 35,000-140,000 | For a 60-100 sq m prefab project; the wide range reflects finish level, country, and duty/tax treatment |
The pattern is consistent: the factory price is usually 40-60% of the final installed cost. Budget for the full chain, not the FOB number.
Prefab Types and Their Price Ranges
- Container house (10ft-40ft): USD 3,800-13,800 per unit FOB. Fastest to install; good for cabins, site offices, and small homes. Expandable and folding designs double the usable area.
- Modular home: USD 80-200/sq ft delivered. Best for full-size houses; factory-built modules joined on a permanent foundation.
- Panelized kit: USD 50-120/sq ft. Flat-packed panels assembled on site; most labour involved, but lowest transport cost.
- Tiny home on wheels: USD 30,000-90,000. Built to trailer standards; classed as a vehicle in many jurisdictions, which affects permit rules.
Where the Money Goes: Hidden Costs to Plan For
- Import duty and tax: the largest variable between countries. Two identical USD 10,000 units can land at very different totals depending on FTA coverage.
- Site access: narrow driveways, overhead wires, and soft ground add crane and transport cost.
- Permits and engineering: structural certification, electrical inspection, and council fees typically run USD 1,000-6,000.
- Connection fees: water, sewer, and power connection charges vary widely by utility and region.
- Finishing upgrades: the factory base price often excludes flooring, kitchen, and bathroom fixtures.
Frequently Asked Questions
How much does a prefab house cost in 2026?
A prefab home costs USD 35,000-140,000 installed for a 60-100 sq m project, depending on type, finish, country, and duty. The factory price alone is typically 40-60% of the total.
Is prefab cheaper than traditional construction?
Usually yes, by 10-25% on the build cost, and the gap widens when you include time savings. A prefab home can be occupied in 2-4 months from order, versus 8-14 months for conventional building.
What is the cheapest type of prefab?
A container house is the lowest entry point — a 10ft unit from USD 3,800 FOB — but it is a small space. For a full house, panelized kits offer the lowest cost per square metre, with modular homes mid-range.
Do prefab prices include installation?
Rarely. FOB quotes exclude freight, duty, tax, foundation, and assembly. Always ask for a landed-and-installed quote with line items.
Are prefab homes mortgageable?
Yes, but lenders treat modular homes on permanent foundations as standard property. Units classed as vehicles or temporary structures (tiny homes on wheels, container cabins without a foundation) usually need alternative financing.
How long does a prefab home last?
Steel-frame and modular homes are engineered for 50+ year service life with normal maintenance. The main factors are corrosion protection, roofing quality, and climate.
