What Does a Factory-Built Home Really Cost?
The true cost of a factory-built home depends on whether you choose a manufactured home or a modular home. Advertised "base prices" only cover the structure itself. [1]
To estimate the actual move-in price, follow the 60/40 rule: the factory structure accounts for roughly 60% of your budget, while the remaining 40% covers land preparation, local permits, foundation installation, and utility hookups. [2]
The shell of the home is highly affordable due to factory optimization. According to the U.S. Census Bureau and recent industry reports, base costs scale by size: [3, 4, 5]
Manufactured (HUD Code) Base Costs: Single-section models average $95,000 to $123,000. Multi-section (double or triple-wide) models average $156,000 to $162,000. The average cost is roughly $87 to $110 per square foot. [4, 6, 7]
Modular (Local Code) Base Costs: Standard modular structures range from $100,000 to $250,000+ just for the floor plans before site delivery. They average $80 to $175 per square foot for the factory modules. [2, 8]
To move into a factory-built house, you must budget for five distinct site-work phases: [1]
Expense Category | Estimated Budget Range | What it Covers |
1. Delivery & Set | $3,000 – $25,000 | State highway permits, pilot cars, transport, and craning modules onto foundations. |
2. Land Prep | $1,250 – $30,000 | Clearing trees, brush removal, rough grading, soil "perc testing", and driveway gravel. |
3. Foundation | $6,000 – $80,000+ | Simple gravel/concrete pads (cheaper) vs. engineered crawl spaces or full basements. |
4. Utility Hookups | $3,000 – $35,000 | Drilling a new well, septic tank installation, and trenching lines to the local electrical grid. |
5. Permits & Fees | $500 – $8,000 | Local municipal building permits, structural engineering reviews, and final impact fees. |
When all site work, structural assembly, and standard utility additions are factored together, total final costs average out to the following: [1]
Small Starter Setup: A 1,000 sq. ft. build on standard property generally costs $80,000 to $150,000 all-in.
Mid-Range Family Size: A standard 1,500 to 2,000 sq. ft. floor plan ranges from $160,000 to $350,000 all-in.
Premium or Remote Setup: Large, highly customized modular structures on rural raw land can run $350,000 to $400,000+. [1, 2, 8]
Even with site costs included, factory-built construction routinely saves 10% to 30% in overall expenses compared to building a custom "stick-built" home from scratch, largely due to minimized labor overhead and protection from weather damage during the build. [1, 3, 9]
