A prefabricated house is a project that usually costs $85,000 to $300,000 before land, depending on whether you choose a manufactured or modular home. In April 2026, U.S. average sales prices were $84,600 for single-section manufactured homes and $164,000 for double-section homes. A 1,500-square-foot modular home often needs a budget of $150,000 to $250,000 before land when the lot has road access and nearby utilities.
Land preparation, foundations, utility connections, permits and landscaping can add $20,000 to $100,000 or more.
Prefabricated House Costs at a Glance
| Type of prefabricated house | Typical cost | What the figure usually means |
|---|---|---|
| Single-section manufactured home | About $84,600 | Average home sales price, excluding many site costs |
| Double-section manufactured home | About $164,000 | Average home sales price, excluding many site costs |
| Modular home, base unit | $50 to $100 per sq. ft. | Factory-built home before site completion |
| Modular home, installed and finished | $80 to $160 per sq. ft. | Home, delivery, installation and typical finishing |
| 1,500-square-foot modular home | $120,000 to $240,000 | Common completed estimate before land |
| Custom modular home | $130 to $310 per sq. ft. | Higher-cost layouts, finishes and upgrades |
The U.S. Census Bureau and Federal Reserve reported April 2026 average sales prices of $84,600 for single-section manufactured homes, $164,000 for double-section homes and $134,800 for all new manufactured homes. These figures cover the home sale price, not the complete cost of developing a finished property.
Published estimates vary by home size, finish level and site conditions. A modular home may cost $120,000 to $270,000 installed, while a custom or high-end project can cost $300,000 or more.
What Is Included in a Prefabricated House Price?
A base modular-home price usually covers factory construction and standard interior systems, but it may leave much of the site work to the buyer.
The base price may include:
- Factory construction
- Standard kitchens and bathrooms
- Basic electrical, plumbing and HVAC systems
- Delivery to the property
- Crane placement or setting the modules
It may exclude:
- Land
- Clearing and grading
- Foundation work
- Utility connections
- Building permits
- Interior or exterior finishing
- Driveway, porch, garage and landscaping
- Sales tax and local fees
HomeGuide estimates that a modular-home base unit costs about $50 to $100 per square foot. Installation, site work and finishing can raise the completed cost to about $80 to $160 per square foot.
How Much Does a 1,000-, 1,500- or 2,000-Square-Foot Modular Home Cost?
A modular home costs about $80 to $160 per square foot when installed and finished, although difficult sites and upgraded features can push the total higher.
| Home size | Base modular unit | Completed estimate |
|---|---|---|
| 1,000 sq. ft. | $50,000 to $100,000 | $80,000 to $160,000 |
| 1,500 sq. ft. | $75,000 to $150,000 | $120,000 to $240,000 |
| 2,000 sq. ft. | $100,000 to $180,000 | $160,000 to $300,000 |
A 1,500-square-foot modular home therefore has a broad completed estimate of $120,000 to $240,000 before land. A planning budget of $150,000 to $250,000 is more practical when delivery, site access and utility work still need to be confirmed. Garages, basements, premium finishes and difficult lots can increase the total.
Manufactured Home Versus Modular Home Cost
Manufactured homes and modular homes are both built in factories, but they are priced and completed differently.
Manufactured Homes
A manufactured home is generally the lower-cost option. It is built as a single-section or multi-section home and transported to the property. The April 2026 average sales prices were $84,600 for single-section homes and $164,000 for double-section homes.
The advertised price may not include:
- Foundation or support system
- Transportation
- Installation and anchoring
- Steps and skirting
- Utility connections
- Site preparation
- Permits and local fees
Modular Homes
A modular home is built in factory sections and assembled on a permanent foundation. It generally costs more than a manufactured home because it allows more floor-plan flexibility, finishes and upgrades.
A modular home generally costs $80 to $160 per square foot when installed and finished, according to current cost estimates.
Additional Prefabricated House Costs
The house itself is only one part of the project. Common additional costs include:
| Project item | Typical estimate |
|---|---|
| Land preparation | $4,000 to $11,000 |
| Foundation | $6,000 to $20,000 |
| Delivery | $3,000 to $12,000 |
| Installation and finishing | $10,000 to $50,000 |
| Utility construction | $2,500 to $25,000 or more |
| Permits and fees | $500 to $4,000 |
| Garage, porch or deck | $5,000 to $50,000 |
| Taxes | $5,000 to $15,000 |
These figures can overlap, so do not add every row automatically. Delivery may already be included in the manufacturer's quote. Utility work may also be priced separately by a local contractor.
Site Conditions Can Change the Budget
A serviced suburban lot with road access, electricity, water and sewer connections will usually cost less to develop than a rural or wooded lot.
Costs can increase when the property requires:
- Tree removal
- Excavation or extensive grading
- A long driveway
- A well and septic system
- Long electrical or water lines
- A basement foundation
- Retaining walls
- Special transportation access for large modules
Angi estimates that a modular-home project may require $3,000 to $20,000 for delivery and $4,000 to $14,900 for a foundation, along with separate costs for water, sewer, electricity and gas connections.
Does a Prefabricated House Include the Land?
Usually, no. The advertised price for a prefabricated house generally excludes the land.
You may also need to pay for:
- Land surveys
- Soil tests
- Zoning approvals
- Impact fees
- Property taxes
- Driveway construction
- Drainage
- Landscaping
- Financing and closing costs
Land can add tens of thousands of dollars or substantially more in high-demand areas. The price depends on location, zoning, road access and whether utilities are already available.
How Should You Compare Prefabricated-Home Quotes?
Compare the complete project price, not just the advertised base price. Ask each builder for a written quote that identifies whether it includes:
- Delivery to your property
- Crane or setting costs
- Foundation construction
- Interior completion after delivery
- Exterior siding, roofing and trim
- HVAC, appliances and fixtures
- Electrical, water and sewer connections
- Building permits and inspections
- Transportation taxes and local fees
- Porches, garages, stairs and landscaping
A lower base price may not produce the lower final cost if it excludes delivery, foundation work or utility connections. A higher quote with more of those items included may be easier to compare and less likely to change later.
Bottom Line
Before land, a typical U.S. buyer should budget approximately:
- $100,000 to $200,000 for a manufactured-home project, depending on size and site conditions
- $150,000 to $300,000 for a standard modular-home project
- $300,000 or more for a custom modular design, upgraded finishes, a basement, garage or difficult building site
The most useful quote separates the cost of the home, delivery, foundation, installation, utilities, permits and land development. That breakdown gives a better estimate than the manufacturer's base price alone.
